However, the same engine is also proven to be useful for other graphical applications, like the Prism editor. + +Although I developed this on macOS, it has been tested on Windows, Linux, iOS, iPadOS and tvOS machines. Apart from some platform glue, these share a majority of the same code! + +## Features +Here is a list of some of the notable features of Prism: + +* Cross platform graphics API is used for rendering + * Vulkan and Metal backends available + * Shaders are written in GLSL, and compiled to SPIR-V or MSL offline and at runtime using SPIRV-Cross. +* Windowing and System abstraction + * main() and other platform-specific tidbits are abstracted as well, for easy support on non-desktop platforms. + * HiDPI is also supported! + * If available, support for multiple windows as well. +* Dear ImGui used for debug/editor UIs + * Includes the new docking/viewport branch! + * Automatic DPI scaling on fonts for crisp rendering when the window is in a HiDPI environment. + * Custom backend built on top the GFX api and other platform agnostic systems. + * Plenty of custom widgets available for easy debug tooling, see imgui_stdlib.h and imgui_utility.hpp! +* Entity-Component system for scene authoring + * No runtime polymorphism is involved and leverages the native C++ type system. Components are simple structs. +* Asset management + * Custom model pipeline allowing for blazingly fast model loading and authoring. + * Includes a custom blender addon for easy export! + * Assets are referenced from disk, and only loaded once - unloaded once they are no longer referenced. + * Thumbnails are created by the editor and stored on disk until further use. +* Custom UI system for easy authoring + * UIs are declared in JSON, and there is a graphical editor available as well. + * They can even be placed in the world with the UI component! +* Custom math library + * Quaternions, matrices, vectors, rays, and more are available! + * Infinite perspective matrices are created by default. +* Advanced rendering techniques + * Rendering is consistent regardless of platform or API used! + * Where older or underperforming GPUs are supported (for example, an Apple TV 4K, or a Thinkpad X230), the engine supports disabling expensive features like IBL or point light shadows along with other scalability options. + * Real-time physically based rendering including scene probes used for image-based lighting. + * Material node editor for easy and fast material authoring. + * Skinned mesh support with animation. + * PCSS for soft shadows, supported on every type of light. +* Editors supporting scene, cutscene, material authoring + * Multidocument workflow similar to UE4. + * Transform handles for easy object manipulation. + +## Usage +### Requirements +* CMake +* Support for Vulkan or Metal +* C++ compiler that fully supports C++17 + * MSVC, Clang, and GCC have been tested + +There is no example available, but if you clone this repository and include it in your cmake tree, use the function `add_platform_executable` from AddPlatformExecutable.cmake to create a new

The UI can be highly dynamic, there are no construction + or destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, less bugs. + - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. + - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. + - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). + You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in the FAQ. + - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. + For every application frame your UI code will be called only once. This is in contrast to e.g. Unity's own implementation of an IMGUI, + where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. + - Our origin are on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. + - This codebase is also optimized to yield decent performances with typical "Debug" builds settings. + - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). + If you get an assert, read the messages and comments around the assert. + - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace. + - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. + See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. + However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase. + - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!). + + + HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI + ---------------------------------------------- + - Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h) + - Or maintain your own branch where you have imconfig.h modified. + - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. + If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed + from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will + likely be a comment about it. Please report any issue to the GitHub page! + - Try to keep your copy of dear imgui reasonably up to date. + + + GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE + --------------------------------------------------------------- + - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. + - In the majority of cases you should be able to use unmodified back-ends files available in the examples/ folder. + - Add the Dear ImGui source files to your projects or using your preferred build system. + It is recommended you build and statically link the .cpp files as part of your project and NOT as shared library (DLL). + - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. + - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. + - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application. All rendering information are stored into command-lists that you will retrieve after calling ImGui::Render(). + - Refer to the bindings and demo applications in the examples/ folder for instruction on how to setup your code. + - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. + + + HOW A SIMPLE APPLICATION MAY LOOK LIKE + -------------------------------------- + EXHIBIT 1: USING THE EXAMPLE BINDINGS (= imgui_impl_XXX.cpp files from the examples/ folder). + The sub-folders in examples/ contains examples applications following this structure. + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Initialize helper Platform and Renderer bindings (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) + ImGui_ImplWin32_Init(hwnd); + ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); + + // Application main loop + while (true) + { + // Feed inputs to dear imgui, start new frame + ImGui_ImplDX11_NewFrame(); + ImGui_ImplWin32_NewFrame(); + ImGui::NewFrame(); + + // Any application code here + ImGui::Text("Hello, world!"); + + // Render dear imgui into screen + ImGui::Render(); + ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); + g_pSwapChain->Present(1, 0); + } + + // Shutdown + ImGui_ImplDX11_Shutdown(); + ImGui_ImplWin32_Shutdown(); + ImGui::DestroyContext(); + + EXHIBIT 2: IMPLEMENTING CUSTOM BINDING / CUSTOM ENGINE + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Build and load the texture atlas into a texture + // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer) + int width, height; + unsigned char* pixels = NULL; + io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); + + // At this point you've got the texture data and you need to upload that your your graphic system: + // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'. + // This will be passed back to your via the renderer.

For more advanced uses, you may want to read from: + - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set. + - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used). + - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions. + Please reach out if you think the game vs navigation input sharing could be improved. + - Gamepad: + - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. + - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame(). + Note that io.NavInputs[] is cleared by EndFrame(). + - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values: + 0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks. + - We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone. + Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.). + - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://goo.gl/9LgVZW. + - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo + to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. + - Mouse: + - PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. + - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard. + - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. + Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements. + When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. + When that happens your back-end NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the binding in examples/ do that. + (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse as moving back and forth!) + (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want + to set a boolean to ignore your other external mouse positions until the external source is moved again.) + + + API BREAKING CHANGES + ==================== + + Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix. + Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. + When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files. + You can read releases logs https://github.com/ocornut/imgui/releases for more details. + + (Docking/Viewport Branch) + - 2019/XX/XX (1.XX) - when multi-viewports are enabled, all positions will be in your natural OS coordinates space. It means that: + - reference to hard-coded positions such as in SetNextWindowPos(ImVec2(0,0)) are probably not what you want anymore. + you may use GetMainViewport()->Pos to offset hard-coded positions, e.g. SetNextWindowPos(GetMainViewport()->Pos) + - likewise io.MousePos and GetMousePos() will use OS coordinates. + If you query mouse positions to interact with non-imgui coordinates you will need to offset them, e.g. subtract GetWindowViewport()->Pos. + - 2019/XX/XX (1.XX) - Moved IME support functions from io.ImeSetInputScreenPosFn, io.ImeWindowHandle to the PlatformIO api. + + + - 2020/04/23 (1.77) - Removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). + - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. + - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. + - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. + - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): + - ShowTestWindow() -> use ShowDemoWindow() + - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) + - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) + - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f) + - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() + - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg + - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding + - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap + - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS + - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was the vaguely documented and rarely if ever used). Instead we added an explicit PrimUnreserve() API. + - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). + - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. + - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): + - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed + - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) + - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() + - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) + - ImFont::Glyph -> use ImFontGlyph + - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. + if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. + The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. + - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). + - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). + - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. + - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have + overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. + This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. + Please reach out if you are affected. + - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). + - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). + - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. + - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). + - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). + - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). + - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with a dummy small value! + - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). + - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! + - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. + - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. + - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. + - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). + - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. + If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. + - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. + - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). + - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). + - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). + - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. + - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. + - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. + - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). + - 2018/06/08 (1.62) - examples: the imgui_impl_xxx files have been split to separate platform (Win32, Glfw, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). + old bindings will still work as is, however prefer using the separated bindings as they will be updated to support multi-viewports. + when adopting new bindings follow the main.cpp code of your preferred examples/ folder to know which functions to call. + in particular, note that old bindings called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. + - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. + - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. + - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. + - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). + - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. + - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some binding ahead of merging the Nav branch). + - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. + - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. + - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. + - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. + - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. + - 2018/02/07 (1.60) - reorganized context handling to be more explicit, + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. + - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. + - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. + - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. + - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). + - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags + - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. + - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. + - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). + - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). + - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). + - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). + - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). + - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. + - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. + - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. + - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. + - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. + - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); + - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. + - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. + - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. + removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. + IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) + IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] + - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! + - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). + - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). + - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your binding if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". + - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! + - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). + - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). + - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. + - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix. + - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. + - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. + - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). + - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). + - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). + - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. + - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. + - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))' + - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse + - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. + - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' + ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. + ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. + - each ImDrawList now contains both a vertex buffer and an index buffer.

Having + two buttons labeled "OK" in different windows or different tree locations is fine. + We used "..." above to signify whatever was already pushed to the ID stack previously: + + Begin("MyWindow"); + Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "OK") + End(); + Begin("MyOtherWindow"); + Button("OK"); // Label = "OK", ID = hash of ("MyOtherWindow", "OK") + End(); + + - If you have a same ID twice in the same location, you'll have a conflict: + + Button("OK"); + Button("OK"); // ID collision! Interacting with either button will trigger the first one. + + Fear not! this is easy to solve and there are many ways to solve it! + + - Solving ID conflict in a simple/local context: + When passing a label you can optionally specify extra ID information within string itself. + Use "##" to pass a complement to the ID that won't be visible to the end-user. + This helps solving the simple collision cases when you know e.g. at compilation time which items + are going to be created: + + Begin("MyWindow"); + Button("Play"); // Label = "Play", ID = hash of ("MyWindow", "Play") + Button("Play##foo1"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo1") // Different from above + Button("Play##foo2"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo2") // Different from above + End(); + + - If you want to completely hide the label, but still need an ID: + + Checkbox("##On", &b); // Label = "", ID = hash of (..., "##On") // No visible label, just a checkbox! + + - Occasionally/rarely you might want change a label while preserving a constant ID. This allows + you to animate labels. For example you may want to include varying information in a window title bar, + but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID: + + Button("Hello###ID"); // Label = "Hello", ID = hash of (..., "###ID") + Button("World###ID"); // Label = "World", ID = hash of (..., "###ID") // Same as above, even though the label looks different + + sprintf(buf, "My game (%f FPS)###MyGame", fps); + Begin(buf); // Variable title, ID = hash of "MyGame" + + - Solving ID conflict in a more general manner: + Use PushID() / PopID() to create scopes and manipulate the ID stack, as to avoid ID conflicts + within the same window. This is the most convenient way of distinguishing ID when iterating and + creating many UI elements programmatically. + You can push a pointer, a string or an integer value into the ID stack. + Remember that ID are formed from the concatenation of _everything_ pushed into the ID stack. + At each level of the stack we store the seed used for items at this level of the ID stack. + + Begin("Window"); + for (int i = 0; i < 100; i++) + { + PushID(i); // Push i to the id tack + Button("Click"); // Label = "Click", ID = hash of ("Window", i, "Click") + PopID(); + } + for (int i = 0; i < 100; i++) + { + MyObject* obj = Objects[i]; + PushID(obj); + Button("Click"); // Label = "Click", ID = hash of ("Window", obj pointer, "Click") + PopID(); + } + for (int i = 0; i < 100; i++) + { + MyObject* obj = Objects[i]; + PushID(obj->Name); + Button("Click"); // Label = "Click", ID = hash of ("Window", obj->Name, "Click") + PopID(); + } + End(); + + - You can stack multiple prefixes into the ID stack: + + Button("Click"); // Label = "Click", ID = hash of (..., "Click") + PushID("node"); + Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click") + PushID(my_ptr); + Button("Click"); // Label = "Click", ID = hash of (..., "node", my_ptr, "Click") + PopID(); + PopID(); + + - Tree nodes implicitly creates a scope for you by calling PushID(). + + Button("Click"); // Label = "Click", ID = hash of (..., "Click") + if (TreeNode("node")) // <-- this function call will do a PushID() for you (unless instructed not to, with a special flag) + { + Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click") + TreePop(); + } + + - When working with trees, ID are used to preserve the open/close state of each tree node. + Depending on your use cases you may want to use strings, indices or pointers as ID. + e.g. when following a single pointer that may change over time, using a static string as ID + will preserve your node open/closed state when the targeted object change. + e.g. when displaying a list of objects, using indices or pointers as ID will preserve the + node open/closed state differently.

Ogg logical bitstream framing

+ +

Ogg bitstreams

+ +

The Ogg transport bitstream is designed to provide framing, error +protection and seeking structure for higher-level codec streams that +consist of raw, unencapsulated data packets, such as the Vorbis audio +codec or Theora video codec.

+ +

Application example: Vorbis

+ +

Vorbis encodes short-time blocks of PCM data into raw packets of +bit-packed data. These raw packets may be used directly by transport +mechanisms that provide their own framing and packet-separation +mechanisms (such as UDP datagrams). For stream based storage (such as +files) and transport (such as TCP streams or pipes), Vorbis uses the +Ogg bitstream format to provide framing/sync, sync recapture +after error, landmarks during seeking, and enough information to +properly separate data back into packets at the original packet +boundaries without relying on decoding to find packet boundaries.

+ +

Design constraints for Ogg bitstreams

+ +
    +
  1. True streaming; we must not need to seek to build a 100% + complete bitstream.
    2. +
  2. Use no more than approximately 1-2% of bitstream bandwidth for + packet boundary marking, high-level framing, sync and seeking.
    3. +
  3. Specification of absolute position within the original sample + stream.
    4. +
  4. Simple mechanism to ease limited editing, such as a simplified + concatenation mechanism.
    5. +
  5. Detection of corruption, recapture after error and direct, random + access to data at arbitrary positions in the bitstream.
    6. +
+ +

Logical and Physical Bitstreams

+ +

A logical Ogg bitstream is a contiguous stream of +sequential pages belonging only to the logical bitstream. A +physical Ogg bitstream is constructed from one or more +than one logical Ogg bitstream (the simplest physical bitstream +is simply a single logical bitstream). We describe below the exact +formatting of an Ogg logical bitstream. Combining logical +bitstreams into more complex physical bitstreams is described in the +Ogg bitstream overview. The exact +mapping of raw Vorbis packets into a valid Ogg Vorbis physical +bitstream is described in the Vorbis I Specification.

+ +

Bitstream structure

+ +

An Ogg stream is structured by dividing incoming packets into +segments of up to 255 bytes and then wrapping a group of contiguous +packet segments into a variable length page preceded by a page +header. Both the header size and page size are variable; the page +header contains sizing information and checksum data to determine +header/page size and data integrity.

+ +

The bitstream is captured (or recaptured) by looking for the beginning +of a page, specifically the capture pattern. Once the capture pattern +is found, the decoder verifies page sync and integrity by computing +and comparing the checksum. At that point, the decoder can extract the +packets themselves.

+ +

Packet segmentation

+ +

Packets are logically divided into multiple segments before encoding +into a page. Note that the segmentation and fragmentation process is a +logical one; it's used to compute page header values and the original +page data need not be disturbed, even when a packet spans page +boundaries.

+ +

The raw packet is logically divided into [n] 255 byte segments and a +last fractional segment of < 255 bytes. A packet size may well +consist only of the trailing fractional segment, and a fractional +segment may be zero length. These values, called "lacing values" are +then saved and placed into the header segment table.

+ +

An example should make the basic concept clear:

+ +
+
+raw packet:
+  ___________________________________________
+ |______________packet data__________________| 753 bytes
+
+lacing values for page header segment table: 255,255,243
+
+
+ +

We simply add the lacing values for the total size; the last lacing +value for a packet is always the value that is less than 255. Note +that this encoding both avoids imposing a maximum packet size as well +as imposing minimum overhead on small packets (as opposed to, eg, +simply using two bytes at the head of every packet and having a max +packet size of 32k. Small packets (<255, the typical case) are +penalized with twice the segmentation overhead). Using the lacing +values as suggested, small packets see the minimum possible +byte-aligned overhead (1 byte) and large packets, over 512 bytes or +so, see a fairly constant ~.5% overhead on encoding space.

+ +

Note that a lacing value of 255 implies that a second lacing value +follows in the packet, and a value of < 255 marks the end of the +packet after that many additional bytes. A packet of 255 bytes (or a +multiple of 255 bytes) is terminated by a lacing value of 0:

+ +

+raw packet:
+  _______________________________
+ |________packet data____________|          255 bytes
+
+lacing values: 255, 0
+
+ +

Note also that a 'nil' (zero length) packet is not an error; it +consists of nothing more than a lacing value of zero in the header.

+ +

Packets spanning pages

+ +

Packets are not restricted to beginning and ending within a page, +although individual segments are, by definition, required to do so. +Packets are not restricted to a maximum size, although excessively +large packets in the data stream are discouraged.

+ +

After segmenting a packet, the encoder may decide not to place all the +resulting segments into the current page; to do so, the encoder places +the lacing values of the segments it wishes to belong to the current +page into the current segment table, then finishes the page. The next +page is begun with the first value in the segment table belonging to +the next packet segment, thus continuing the packet (data in the +packet body must also correspond properly to the lacing values in the +spanned pages. The segment data in the first packet corresponding to +the lacing values of the first page belong in that page; packet +segments listed in the segment table of the following page must begin +the page body of the subsequent page).

+ +

The last mechanic to spanning a page boundary is to set the header +flag in the new page to indicate that the first lacing value in the +segment table continues rather than begins a packet; a header flag of +0x01 is set to indicate a continued packet. Although mandatory, it +is not actually algorithmically necessary; one could inspect the +preceding segment table to determine if the packet is new or +continued. Adding the information to the packet_header flag allows a +simpler design (with no overhead) that needs only inspect the current +page header after frame capture. This also allows faster error +recovery in the event that the packet originates in a corrupt +preceding page, implying that the previous page's segment table +cannot be trusted.

+ +

Note that a packet can span an arbitrary number of pages; the above +spanning process is repeated for each spanned page boundary. Also a +'zero termination' on a packet size that is an even multiple of 255 +must appear even if the lacing value appears in the next page as a +zero-length continuation of the current packet. The header flag +should be set to 0x01 to indicate that the packet spanned, even though +the span is a nil case as far as data is concerned.

+ +

The encoding looks odd, but is properly optimized for speed and the +expected case of the majority of packets being between 50 and 200 +bytes (note that it is designed such that packets of wildly different +sizes can be handled within the model; placing packet size +restrictions on the encoder would have only slightly simplified design +in page generation and increased overall encoder complexity).

+ +

The main point behind tracking individual packets (and packet +segments) is to allow more flexible encoding tricks that requiring +explicit knowledge of packet size. An example is simple bandwidth +limiting, implemented by simply truncating packets in the nominal case +if the packet is arranged so that the least sensitive portion of the +data comes last.

+ + +

Page header

+ +

The headering mechanism is designed to avoid copying and re-assembly +of the packet data (ie, making the packet segmentation process a +logical one); the header can be generated directly from incoming +packet data. The encoder buffers packet data until it finishes a +complete page at which point it writes the header followed by the +buffered packet segments.

+ +

capture_pattern

+ +

A header begins with a capture pattern that simplifies identifying +pages; once the decoder has found the capture pattern it can do a more +intensive job of verifying that it has in fact found a page boundary +(as opposed to an inadvertent coincidence in the byte stream).

+ +

+ byte value
+
+  0  0x4f 'O'
+  1  0x67 'g'
+  2  0x67 'g'
+  3  0x53 'S'  
+
+ +

stream_structure_version

+ +

The capture pattern is followed by the stream structure revision:

+ +

+ byte value
+
+  4  0x00
+
+ +

header_type_flag

+ +

The header type flag identifies this page's context in the bitstream:

+ +

+ byte value
+
+  5  bitflags: 0x01: unset = fresh packet
+	               set = continued packet
+	       0x02: unset = not first page of logical bitstream
+                       set = first page of logical bitstream (bos)
+	       0x04: unset = not last page of logical bitstream
+                       set = last page of logical bitstream (eos)
+
+ +

absolute granule position

+ +

(This is packed in the same way the rest of Ogg data is packed; LSb +of LSB first. Note that the 'position' data specifies a 'sample' +number (eg, in a CD quality sample is four octets, 16 bits for left +and 16 bits for right; in video it would likely be the frame number. +It is up to the specific codec in use to define the semantic meaning +of the granule position value). The position specified is the total +samples encoded after including all packets finished on this page +(packets begun on this page but continuing on to the next page do not +count). The rationale here is that the position specified in the +frame header of the last page tells how long the data coded by the +bitstream is. A truncated stream will still return the proper number +of samples that can be decoded fully.

+ +

A special value of '-1' (in two's complement) indicates that no packets +finish on this page.

+ +

+ byte value
+
+  6  0xXX LSB
+  7  0xXX
+  8  0xXX
+  9  0xXX
+ 10  0xXX
+ 11  0xXX
+ 12  0xXX
+ 13  0xXX MSB
+
+ +

stream serial number

+ +

Ogg allows for separate logical bitstreams to be mixed at page +granularity in a physical bitstream. The most common case would be +sequential arrangement, but it is possible to interleave pages for +two separate bitstreams to be decoded concurrently. The serial +number is the means by which pages physical pages are associated with +a particular logical stream. Each logical stream must have a unique +serial number within a physical stream:

+ +

+ byte value
+
+ 14  0xXX LSB
+ 15  0xXX
+ 16  0xXX
+ 17  0xXX MSB
+
+ +

page sequence no

+ +

Page counter; lets us know if a page is lost (useful where packets +span page boundaries).

+ +

+ byte value
+
+ 18  0xXX LSB
+ 19  0xXX
+ 20  0xXX
+ 21  0xXX MSB
+
+ +

page checksum

+ +

32 bit CRC value (direct algorithm, initial val and final XOR = 0, +generator polynomial=0x04c11db7). The value is computed over the +entire header (with the CRC field in the header set to zero) and then +continued over the page. The CRC field is then filled with the +computed value.

+ +

(A thorough discussion of CRC algorithms can be found in "A +Painless Guide to CRC Error Detection Algorithms" by Ross +Williams ross@ross.net.)

+ +

+ byte value
+
+ 22  0xXX LSB
+ 23  0xXX
+ 24  0xXX
+ 25  0xXX MSB
+
+ +

page_segments

+ +

The number of segment entries to appear in the segment table. The +maximum number of 255 segments (255 bytes each) sets the maximum +possible physical page size at 65307 bytes or just under 64kB (thus +we know that a header corrupted so as destroy sizing/alignment +information will not cause a runaway bitstream. We'll read in the +page according to the corrupted size information that's guaranteed to +be a reasonable size regardless, notice the checksum mismatch, drop +sync and then look for recapture).

+ +

+ byte value
+
+ 26 0x00-0xff (0-255)
+
+ +

segment_table (containing packet lacing values)

+ +

The lacing values for each packet segment physically appearing in +this page are listed in contiguous order.

+ +

+ byte value
+
+ 27 0x00-0xff (0-255)
+ [...]
+ n  0x00-0xff (0-255, n=page_segments+26)
+
+ +

Total page size is calculated directly from the known header size and +lacing values in the segment table. Packet data segments follow +immediately after the header.

+ +

Page headers typically impose a flat .25-.5% space overhead assuming +nominal ~8k page sizes. The segmentation table needed for exact +packet recovery in the streaming layer adds approximately .5-1% +nominal assuming expected encoder behavior in the 44.1kHz, 128kbps +stereo encodings.

Decoding

+

Libogg contains a set of functions used in the decoding process. +

+All the libogg specific functions are declared in "ogg/ogg.h". +

+

Decoding is based around the ogg synchronization layer. The ogg_sync_state struct coordinates between incoming data and the decoder. We read data into the synchronization layer, submit the data to the stream, and output raw packets to the decoder. +

Decoding through the Ogg layer follows a specific logical sequence. A read loop follows these logical steps: +

+

In practice, streams are more complex, and Ogg also must handle headers, incomplete or dropped pages, and other errors in input. +

Raw packets are inserted into the stream, and an ogg_page is output when enough packets have been written to create a full page. The pages output are pointers to buffered packet segments, and can then be written out and saved as an ogg stream. +

There are a couple of basic steps: +

    +
  • Use the encoding engine to produce a raw packet of data. +
  • Call ogg_stream_packetin to submit a raw packet to the stream. +
  • Use ogg_stream_pageout to output a page, if enough data has been submitted. Otherwise, continue submitting data. +
+

+ + + + + + + + + + + + + + + + + + + + + + + + + + +

General Functions

+

Libogg contains several functions which are generally useful when using Ogg streaming, whether encoding or decoding. +

+All the libogg specific functions are declared in "ogg/ogg.h". +

+

These functions can be used to manipulate some of the basic elements of Ogg - streams and pages. Streams and pages are important during both the encode and decode process. +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
functionpurpose
ogg_stream_initInitializes an Ogg bitstream.
ogg_stream_clearClears the storage within the Ogg stream, but does not free the stream itself. +
ogg_stream_resetResets the stream status to its initial position.
ogg_stream_destroyFrees the entire Ogg stream.
ogg_stream_checkCheck for asynchronous errors.
ogg_stream_eosIndicates whether we are at the end of the stream.
ogg_page_versionReturns the version of ogg_page that this stream/page uses
ogg_page_continuedIndicates if the current page contains a continued packet from the last page.
ogg_page_packetsIndicates the number of packets contained in a page.
ogg_page_bosIndicates if the current page is the beginning of the stream.
ogg_page_eosIndicates if the current page is the end of the stream.
ogg_page_granuleposReturns the precise playback location of this page.
ogg_page_serialnoReturns the unique serial number of the logical bitstream associated with this page.
ogg_page_pagenoReturns the sequential page number for this page.
ogg_packet_clearClears the ogg_packet structure.
ogg_page_checksum_setChecksums an ogg_page.

    ogg_page

    declared in "ogg/ogg.h"

    + +

    +The ogg_page struct encapsulates the data for an Ogg page. +

    +Ogg pages are the fundamental unit of framing and interleave in an ogg bitstream. +They are made up of packet segments of 255 bytes each. There can be as many as +255 packet segments per page, for a maximum page size of a little under 64 kB. +This is not a practical limitation as the segments can be joined across +page boundaries allowing packets of arbitrary size. In practice many +applications will not completely fill all pages because they flush the +accumulated packets periodically order to bound latency more tightly. +

    +

    For a complete description of ogg pages and headers, please refer to the framing document. + + + + + +

+int ogg_page_version(ogg_page *og);
+
+
    +
    + +

    Parameters

    +
    +
    og
    +
    Pointer to the current ogg_page struct.
    +
    + + +

    Return Values

    +
    +
  • +n is the version number. In the current version of Ogg, the version number is always 0. Nonzero return values indicate an error in page encoding.

    + +

    ogg_stream_check

    + +

    declared in "ogg/ogg.h";

    + +

    This function is used to check the error or readiness condition of an ogg_stream_state structure. +

    It is safe practice to ignore unrecoverable errors (such as an internal error caused by a malloc() failure) returned by ogg stream synchronization calls. Should an +internal error occur, the ogg_stream_state structure will be cleared (equivalent to a +call to +ogg_stream_clear) and subsequent calls +using this ogg_stream_state will be +noops. Error detection is then handled via a single call to +ogg_stream_check at the end of the operational block.

    + +

    + + + + +
    +
    
+int ogg_stream_check(ogg_stream_state *os);
+
    +
    + +

    Parameters

    +
    +
    os
    +
    Pointer to a previously declared ogg_stream_state struct.
    +
    + + +

    Return Values

    +
    +
  • +0 is returned if the ogg_stream_state structure is initialized and ready.
    • +
  • +nonzero is returned if the structure was never initialized, or if an unrecoverable internal error occurred in a previous call using the passed in ogg_stream_state struct.
    • +

    ogg_stream_destroy

    + +

    declared in "ogg/ogg.h";

    + +

    This function frees the internal memory used by +the ogg_stream_state struct as +well as the structure itself. + +

    This should be called when you are done working with an ogg stream. +It can also be called to make sure that the struct does not exist.

    It calls free() on its argument, so if the ogg_stream_state +is not malloc()'d or will otherwise be freed by your own code, use +ogg_stream_clear instead.

    ogg_stream_flush

    + +

    declared in "ogg/ogg.h";

    + +

    This function checks for remaining packets inside the stream and forces remaining packets into a page, regardless of the size of the page. +

    This should only be used when you want to flush an undersized page from the middle of the stream. Otherwise, ogg_stream_pageout or ogg_stream_pageout_fill should always be used. +

    This function can also be used to verify that all packets have been flushed. If the return value is 0, all packets have been placed into a page. Like ogg_stream_pageout, it should generally be called in a loop until available packet data has been flushes, since even a single packet may span multiple pages. + +

    + + + + +
    +
    
+int ogg_stream_flush(ogg_stream_state *os, ogg_page *og);

    +
    os
    +
    Pointer to a previously declared ogg_stream_state struct, which represents the current logical bitstream.
    +
    og
    +
    Pointer to a page of data. The remaining packets in the stream will be placed into this page, if any remain. +
    + + +

    Return Values

    +
    +
  • 0 means that all packet data has already been flushed into pages, and there are no packets to put into the page. 0 is also returned in the case of an ogg_stream_state that has been cleared explicitly or implicitly due to an internal error.

    ogg_stream_flush_fill

    + +

    declared in "ogg/ogg.h";

    + +

    This function flushes available packets into pages, similar to +ogg_stream_flush(), but +allows applications to explicitly request a specific page spill +size.

    + +

    This function checks for remaining packets inside the stream and forces remaining packets into pages of approximately the requested size. +This should be used when you want to flush all remaining data from a stream. ogg_stream_flush may be used instead if a particular page size isn't important. +

    This function can be used to verify that all packets have been flushed. If the return value is 0, all packets have been placed into a page. Generally speaking, it should be called in a loop until all packets are flushed, since even a single packet may span multiple pages. + +

    +
    
+int ogg_stream_flush_fill(ogg_stream_state *os, ogg_page *og, int fillbytes);
+
    +
    + +

    Parameters

    +
    +
    os
    +
    Pointer to a previously declared ogg_stream_state struct, which represents the current logical bitstream.
    +
    og
    +
    Pointer to a page of data. The remaining packets in the stream will be placed into this page, if any remain. +
    fillbytes
    +
    Packet data watermark in bytes.
    +
    + + +

    Return Values

    +
    +
  • 0 means that all packet data has already been flushed into pages, and there are no packets to put into the page. 0 is also returned in the case of an ogg_stream_state that has been cleared explicitly or implicitly due to an internal error.

    ogg_stream_packetout

    + +

    declared in "ogg/ogg.h";

    + +

    This function assembles a data packet for output to the codec +decoding engine. The data has already been submitted to the +ogg_stream_state and broken +into segments. Each successive call returns the next complete packet +built from those segments.

    + +

    In a typical decoding situation, this should be used after calling +ogg_stream_pagein() to submit a +page of data to the bitstream. If the function returns 0, more data is +needed and another page should be submitted. A non-zero return value +indicates successful return of a packet.

    + +

    The op is filled in with pointers to memory managed by +the stream state and is only valid until the next call. The client +must copy the packet data if a longer lifetime is required.

    + + + + +
    +
    
+int ogg_stream_packetout(ogg_stream_state *os,ogg_packet *op);

    Parameters

    +
    +
    os
    +
    Pointer to a previously declared ogg_stream_state struct. Before this function is called, an ogg_page should be submitted to the stream using ogg_stream_pagein().
    +
    op
    +
    Pointer to the packet to be filled in with pointers to the new data. +This will typically be submitted to a codec for decode after this +function is called. The pointers are only valid until the next call +on this stream state.
    +
    + + +

    Return Values

    +
    +
      +
    • -1 if we are out of sync and there is a gap in the data. This is usually a recoverable error and subsequent calls to ogg_stream_packetout are likely to succeed. op has not been updated.
      • +
    • 0 if there is insufficient data available to complete a packet, or on unrecoverable internal error occurred. op has not been updated. +
    • 1 if a packet was assembled normally. op contains the next packet from the stream.

    + +

    ogg_stream_pageout

    + +

    declared in "ogg/ogg.h";

    + +

    This function forms packets into pages.

    + +

    In a typical encoding situation, this would be called after using ogg_stream_packetin() to submit +data packets to the bitstream. Internally, this function assembles +the accumulated packet bodies into an Ogg page suitable for writing +to a stream. The function is typically called in a loop until there +are no more pages ready for output.

    + +

    This function will only return a page when a "reasonable" amount of +packet data is available. Normally this is appropriate since it +limits the overhead of the Ogg page headers in the bitstream, and so +calling ogg_stream_pageout() after ogg_stream_packetin() should be the +common case. Call ogg_stream_flush() +if immediate page generation is desired. This may be occasionally +necessary, for example, to limit the temporal latency of a variable +bitrate stream.

    + +

    + + + + +
    +
    
+int ogg_stream_pageout(ogg_stream_state *os, ogg_page *og);
+
    +
    + +

    Parameters

    +
    +
    os
    +
    Pointer to a previously declared ogg_stream struct, which represents the current logical bitstream.
    +
    og
    +
    Pointer to an ogg_page structure to fill +in. Data pointed to is owned by libogg. The structure is valid until the +next call to ogg_stream_pageout(), ogg_stream_packetin(), or +ogg_stream_flush().
    +
    + + +

    Return Values

    +
    +
  • Zero means that insufficient data has accumulated to fill a page, or an internal error occurred. In +this case og is not modified.
    • +
  • Non-zero means that a page has been completed and returned.
    • +

    ogg_stream_pageout_fill

    + +

    declared in "ogg/ogg.h";

    + +

    This function forms packets into pages, similar +to ogg_stream_pageout(), but +allows applications to explicitly request a specific page spill +size.

    + +

    In a typical encoding situation, this would be called after using ogg_stream_packetin() to submit +data packets to the bitstream. Internally, this function assembles +the accumulated packet bodies into an Ogg page suitable for writing +to a stream. The function is typically called in a loop until there +are no more pages ready for output.

    + +

    This function will return a page when at least four packets have +been accumulated and accumulated packet data meets or exceeds the +specified number of bytes, and/or when the accumulated packet +data meets/exceeds the maximum page size regardless of accumulated +packet count. +Call ogg_stream_flush() or +ogg_stream_flush_fill() if +immediate page generation is desired regardless of accumulated data.

    + +

    + + + + +
    +
    
+int ogg_stream_pageout_fill(ogg_stream_state *os, ogg_page *og, int fillbytes);

    +
    + +

    Parameters

    +
    +
    os
    +
    Pointer to a previously declared ogg_stream struct, which represents the current logical bitstream.
    +
    og
    +
    Pointer to an ogg_page structure to fill +in. Data pointed to is owned by libogg. The structure is valid until the +next call to ogg_stream_pageout(), ogg_stream_packetin(), or +ogg_stream_flush().
    +
    fillbytes
    +
    Packet data watermark in bytes.
    +
    + + +

    Return Values

    +
    +
  • Zero means that insufficient data has accumulated to fill a page, or an internal error occurred. In +this case og is not modified.

    ogg_sync_buffer

    + +

    declared in "ogg/ogg.h";

    + +

    This function is used to provide a properly-sized buffer for writing. +

    Buffer space which has already been returned is cleared, and the buffer is extended as necessary by the size plus some additional bytes. Within the current implementation, an extra 4096 bytes are allocated, but applications should not rely on this additional buffer space. +

    The buffer exposed by this function is empty internal storage from the ogg_sync_state struct, beginning at the fill mark within the struct. +

    A pointer to this buffer is returned to be used by the calling application. + +

    + + + + +
    +

    oy
    +
    Pointer to a previously declared ogg_sync_state struct.
    +
    size
    +
    Size of the desired buffer. The actual size of the buffer returned will be this size plus some extra bytes (currently 4096). +

    ogg_sync_check

    + +

    declared in "ogg/ogg.h";

    + +

    This function is used to check the error or readiness condition of an ogg_sync_state structure. +

    It is safe practice to ignore unrecoverable errors (such as an internal error caused by a malloc() failure) returned by ogg stream synchronization calls. Should an +internal error occur, the ogg_sync_state structure will be cleared (equivalent to a +call to +ogg_sync_clear) and subsequent calls +using this ogg_sync_state will be +noops. Error detection is then handled via a single call to +ogg_sync_check at the end of the operational block.

    + +

    + + + + +
    +
    
+int ogg_sync_check(ogg_sync_state *oy);
+
    +
    + +

    Parameters

    +
    +
    oy
    +
    Pointer to a previously declared ogg_sync_state struct.
    +
    + + +

    Return Values

    +
    +
  • +0 is returned if the ogg_sync_state structure is initialized and ready.
    • +
  • +nonzero is returned if the structure was never initialized, or if an unrecoverable internal error occurred in a previous call using the passed in ogg_sync_state struct.

    This function takes the data stored in the buffer of the ogg_sync_state struct and inserts them into an ogg_page. + +

    Caution:This function should be called before reading into the buffer to ensure that data does not remain in the ogg_sync_state struct. Failing to do so may result in a memory leak. See the example code below for details. + +

    + + + + +
    +
    
+int ogg_sync_pageout(ogg_sync_state *oy, ogg_page *og);
+
    +
    + +

    Parameters

    +
    +
    oy
    +
    Pointer to a previously declared ogg_sync_state struct. Normally, the internal storage of this struct should be filled with newly read data and verified using ogg_sync_wrote.
    +
    og
    +
    Pointer to page struct filled by this function. +
    + + +

    Return Values

    +
    +
  • -1 returned if stream has not yet captured sync (bytes were skipped).
    • +
  • 0 returned if more data needed or an internal error occurred.
    • +
  • 1 indicated a page was synced and returned.
    • +
    +

    + +

    Example Usage

    +
    +if (ogg_sync_pageout(&oy, &og) != 1) {
+	buffer = ogg_sync_buffer(&oy, 8192);
+	bytes = fread(buffer, 1, 8192, stdin);
+	ogg_sync_wrote(&oy, bytes);
+}
+

    ogg_sync_pageseek

    + +

    declared in "ogg/ogg.h";

    + +

    This function synchronizes the ogg_sync_state struct to the next ogg_page. +

    This is useful when seeking within a bitstream. ogg_sync_pageseek will synchronize to the next page in the bitstream and return information about how many bytes we advanced or skipped in order to do so. + +

    + + + + +
    +
    
+int ogg_sync_pageseek(ogg_sync_state *oy, ogg_page *og);
+
    +
    + +

    Parameters

    +
    +
    oy
    +
    Pointer to a previously declared ogg_sync_state struct.
    +
    og
    +
    Pointer to a page (or an incomplete page) of data. This is the page we are attempting to sync. +
    + + +

    Return Values

    +
    +
  • -n means that we skipped n bytes within the bitstream.
    • +
  • +0 means that the page isn't ready and we need more data, or than an internal error occurred. No bytes have been skipped.
    • +
  • +n means that the page was synced at the current location, with a page length of n bytes. +
    • +

    ogg_sync_wrote

    + +

    declared in "ogg/ogg.h";

    + +

    This function is used to tell the ogg_sync_state struct how many bytes we wrote into the buffer. + +

    +The general procedure is to request a pointer into an internal +ogg_sync_state buffer by calling +ogg_sync_buffer(). The buffer +is then filled up to the requested size with new input, and +ogg_sync_wrote() is called to advance the fill pointer by however +much data was actually available.

    oy
    +
    Pointer to a previously declared ogg_sync_state struct.
    +
    bytes
    +
    Number of bytes of new data written.
    +
    + + +

    Return Values

    +
    +

    oggpack_writecheck

    + +

    declared in "ogg/ogg.h";

    + +

    This function checks the readiness status of +an oggpack_buffer previously +initialized for writing using the +Ogg bitpacking functions. A write +buffer that encounters an error (such as a failed malloc) will clear +its internal state and release any in-use memory, flagging itself as +'not ready'. Subsequent attempts to write using the buffer will +silently fail. This error state may be detected at any later time by +using oggpack_writecheck(). It is safe but not necessary to +call oggpack_writeclear() on a buffer that +has flagged an error and released its resources. + +

    Important note to developers: Although libogg checks the +results of memory allocations, these checks are only useful on a +narrow range of embedded platforms. Allocation checks perform no +useful service on a general purpose desktop OS where pages are +routinely overallocated and all allocations succeed whether memory is +available or not. The only way to detect an out of memory condition +on the vast majority of OSes is to watch for and capture segmentation +faults. This function is useful only to embedded developers. + +

    Parameters

    b
    +

  • zero: buffer is ready for writing

  • nonzero: buffer is not ready or encountered an error

    Page Multiplexing and Ordering in a Physical Ogg Stream

    + +

    The low-level mechanisms of an Ogg stream (as described in the Ogg +Bitstream Overview) provide means for mixing multiple logical streams +and media types into a single linear-chronological stream. This +document specifies the high-level arrangement and use of page +structure to multiplex multiple streams of mixed media type within a +physical Ogg stream.

    + +

    Design Elements

    + +

    The design and arrangement of the Ogg container format is governed by +several high-level design decisions that form the reasoning behind +specific low-level design decisions.

    + +

    Linear media

    + +

    The Ogg bitstream is intended to encapsulate chronological, +time-linear mixed media into a single delivery stream or file. The +design is such that an application can always encode and/or decode a +full-featured bitstream in one pass with no seeking and minimal +buffering. Seeking to provide optimized encoding (such as two-pass +encoding) or interactive decoding (such as scrubbing or instant +replay) is not disallowed or discouraged, however no bitstream feature +must require nonlinear operation on the bitstream.

    + +

    Multiplexing

    + +

    Ogg bitstreams multiplex multiple logical streams into a single +physical stream at the page level. Each page contains an abstract +time stamp (the Granule Position) that represents an absolute time +landmark within the stream. After the pages representing stream +headers (all logical stream headers occur at the beginning of a +physical bitstream section before any logical stream data), logical +stream data pages are arranged in a physical bitstream in strict +non-decreasing order by chronological absolute time as +specified by the granule position.

    + +

    The only exception to arranging pages in strictly ascending time order +by granule position is those pages that do not set the granule +position value. This is a special case when exceptionally large +packets span multiple pages; the specifics of handling this special +case are described later under 'Continuous and Discontinuous +Streams'.

    + +

    Seeking

    + +

    Ogg is designed to use an interpolated bisection search to +implement exact positional seeking. Interpolated bisection search is +a spec-mandated mechanism.

    + +

    An index may improve objective performance, but it seldom +improves subjective performance outside of a few high-latency use +cases and adds no additional functionality as bisection search +delivers the same functionality for both one- and two-pass stream +types. For these reasons, use of indexes is discouraged, except in +cases where an index provides demonstrable and noticeable performance +improvement.

    + +

    Seek operations are by absolute time; a direct bisection search must +find the exact time position requested. Information in the Ogg +bitstream is arranged such that all information to be presented for +playback from the desired seek point will occur at or after the +desired seek point. Seek operations are neither 'fuzzy' nor +heuristic.

    + +

    Although key frame handling in video appears to be an exception to +"all needed playback information lies ahead of a given seek", +key frames can still be handled directly within this indexless +framework. Seeking to a key frame in video (as well as seeking in other +media types with analogous restraints) is handled as two seeks; first +a seek to the desired time which extracts state information that +decodes to the time of the last key frame, followed by a second seek +directly to the key frame. The location of the previous key frame is +embedded as state information in the granulepos; this mechanism is +described in more detail later.

    + +

    Continuous and Discontinuous Streams

    + +

    Logical streams within a physical Ogg stream belong to one of two +categories, "Continuous" streams and "Discontinuous" streams. +Although these are discussed in more detail later, the distinction is +important to a high-level understanding of how to buffer an Ogg +stream.

    + +

    A stream that provides a gapless, time-continuous media type with a +fine-grained timebase is considered to be 'Continuous'. A continuous +stream should never be starved of data. Clear examples of continuous +data types include broadcast audio and video.

    + +

    A stream that delivers data in a potentially irregular pattern or with +widely spaced timing gaps is considered to be 'Discontinuous'. A +discontinuous stream may be best thought of as data representing +scattered events; although they happen in order, they are typically +unconnected data often located far apart. One possible example of a +discontinuous stream types would be captioning. Although it's +possible to design captions as a continuous stream type, it's most +natural to think of captions as widely spaced pieces of text with +little happening between.

    + +

    The fundamental design distinction between continuous and +discontinuous streams concerns buffering.

    + +

    Buffering

    + +

    Because a continuous stream is, by definition, gapless, Ogg buffering +is based on the simple premise of never allowing any active continuous +stream to starve for data during decode; buffering proceeds ahead +until all continuous streams in a physical stream have data ready to +decode on demand.

    + +

    Discontinuous stream data may occur on a fairly regular basis, but the +timing of, for example, a specific caption is impossible to predict +with certainty in most captioning systems. Thus the buffering system +should take discontinuous data 'as it comes' rather than working ahead +(for a potentially unbounded period) to look for future discontinuous +data. As such, discontinuous streams are ignored when managing +buffering; their pages simply 'fall out' of the stream when continuous +streams are handled properly.

    + +

    Buffering requirements need not be explicitly declared or managed for +the encoded stream; the decoder simply reads as much data as is +necessary to keep all continuous stream types gapless (also ensuring +discontinuous data arrives in time) and no more, resulting in optimum +implicit buffer usage for a given stream. Because all pages of all +data types are stamped with absolute timing information within the +stream, inter-stream synchronization timing is always explicitly +maintained without the need for explicitly declared buffer-ahead +hinting.

    + +

    Further details, mechanisms and reasons for the differing arrangement +and behavior of continuous and discontinuous streams is discussed +later.

    + +

    Whole-stream navigation

    + +

    Ogg is designed so that the simplest navigation operations treat the +physical Ogg stream as a whole summary of its streams, rather than +navigating each interleaved stream as a separate entity.

    + +

    First Example: seeking to a desired time position in a multiplexed (or +unmultiplexed) Ogg stream can be accomplished through a bisection +search on time position of all pages in the stream (as encoded in the +granule position). More powerful searches (such as a key frame-aware +seek within video) are also possible with additional search +complexity, but similar computational complexity.

    + +

    Second Example: A bitstream section may consist of three multiplexed +streams of differing lengths. The result of multiplexing these +streams should be thought of as a single mixed stream with a length +equal to the longest of the three component streams. Although it is +also possible to think of the multiplexed results as three concurrent +streams of different lengths and it is possible to recover the three +original streams, it will also become obvious that once multiplexed, +it isn't possible to find the internal lengths of the component +streams without a linear search of the whole bitstream section. +However, it is possible to find the length of the whole bitstream +section easily (in near-constant time per section) just as it is for a +single-media unmultiplexed stream.

    + +

    Granule Position

    + +

    Description

    + +

    The Granule Position is a signed 64 bit field appearing in the header +of every Ogg page. Although the granule position represents absolute +time within a logical stream, its value does not necessarily directly +encode a simple timestamp. It may represent frames elapsed (as in +Vorbis), a simple timestamp, or a more complex bit-division encoding +(such as in Theora). The exact encoding of the granule position is up +to a specific codec.

    + +

    The granule position is governed by the following rules:

    + +
      + +
    • Granule Position must always increase forward or remain equal from +page to page, be unset, or be zero for a header page. The absolute +time to which any correct sequence of granule position maps must +similarly always increase forward or remain equal. (A codec may +make use of data, such as a control sequence, that only affects codec +working state without producing data and thus advancing granule +position and time. Although the packet sequence number increases in +this case, the granule position, and thus the time position, do +not.)
      • + +
    • Granule position may only be unset if there no packet defining a +time boundary on the page (that is, if no packet in a continuous +stream ends on the page, or no packet in a discontinuous stream begins +on the page. This will be discussed in more detail under Continuous +and Discontinuous streams).
      • + +
    • A codec must be able to translate a given granule position value +to a unique, deterministic absolute time value through direct +calculation. A codec is not required to be able to translate an +absolute time value into a unique granule position value.
      • + +
    • Codecs shall choose a granule position definition that allows that +codec means to seek as directly as possible to an immediately +decodable point, such as the bit-divided granule position encoding of +Theora allows the codec to seek efficiently to key frame without using +an index. That is, additional information other than absolute time +may be encoded into a granule position value so long as the granule +position obeys the above points.
      • + +
    + +

    Example: timestamp

    + +

    In general, a codec/stream type should choose the simplest granule +position encoding that addresses its requirements. The examples here +are by no means exhaustive of the possibilities within Ogg.

    + +

    A simple granule position could encode a timestamp directly. For +example, a granule position that encoded milliseconds from beginning +of stream would allow a logical stream length of over 100,000,000,000 +days before beginning a new logical stream (to avoid the granule +position wrapping).

    + +

    Example: framestamp

    + +

    A simple millisecond timestamp granule encoding might suit many stream +types, but a millisecond resolution is inappropriate to, eg, most +audio encodings where exact single-sample resolution is generally a +requirement. A millisecond is both too large a granule and often does +not represent an integer number of samples.

    + +

    In the event that audio frames are always encoded as the same number of +samples, the granule position could simply be a linear count of frames +since beginning of stream. This has the advantages of being exact and +efficient. Position in time would simply be [granule_position] * +[samples_per_frame] / [samples_per_second].

    + +

    Example: samplestamp (Vorbis)

    + +

    Frame counting is insufficient in codecs such as Vorbis where an audio +frame [packet] encodes a variable number of samples. In Vorbis's +case, the granule position is a count of the number of raw samples +from the beginning of stream; the absolute time of +a granule position is [granule_position] / +[samples_per_second].

    + +

    Example: bit-divided framestamp (Theora)

    + +

    Some video codecs may be able to use the simple framestamp scheme for +granule position. However, most modern video codecs introduce at +least the following complications:

    + +
      + +
    • video frames are relatively far apart compared to audio samples; +for this reason, the point at which a video frame changes to the next +frame is usually a strictly defined offset within the frame 'period'. +That is, video at 50fps could just as easily define frame transitions +<.015, .035, .055...> as at <.00, .02, .04...>.
      • + +
    • frame rates often include drop-frames, leap-frames or other +rational-but-non-integer timings.
      • + +
    • Decode must begin at a 'key frame' or 'I frame'. Keyframes usually +occur relatively seldom.
      • + +
    + +

    The first two points can be handled straightforwardly via the fact +that the codec has complete control mapping granule position to +absolute time; non-integer frame rates and offsets can be set in the +codec's initial header, and the rest is just arithmetic.

    + +

    The third point appears trickier at first glance, but it too can be +handled through the granule position mapping mechanism. Here we +arrange the granule position in such a way that granule positions of +key frames are easy to find. Divide the granule position into two +fields; the most-significant bits are an absolute frame counter, but +it's only updated at each key frame. The least significant bits encode +the number of frames since the last key frame. In this way, each +granule position both encodes the absolute time of the current frame +as well as the absolute time of the last key frame.

    + +

    Seeking to a most recent preceding key frame is then accomplished by +first seeking to the original desired point, inspecting the granulepos +of the resulting video page, extracting from that granulepos the +absolute time of the desired key frame, and then seeking directly to +that key frame's page. Of course, it's still possible for an +application to ignore key frames and use a simpler seeking algorithm +(decode would be unable to present decoded video until the next +key frame). Surprisingly many player applications do choose the +simpler approach.

    + +

    granule position, packets and pages

    + +

    Although each packet of data in a logical stream theoretically has a +specific granule position, only one granule position is encoded +per page. It is possible to encode a logical stream such that each +page contains only a single packet (so that granule positions are +preserved for each packet), however a one-to-one packet/page mapping +is not intended to be the general case.

    + +

    Because Ogg functions at the page, not packet, level, this +once-per-page time information provides Ogg with the finest-grained +time information is can use. Ogg passes this granule positioning data +to the codec (along with the packets extracted from a page); it is the +responsibility of codecs to track timing information at granularities +finer than a single page.

    + +

    start-time and end-time positioning

    + +

    A granule position represents the instantaneous time location +between two pages. However, continuous streams and discontinuous +streams differ on whether the granulepos represents the end-time of +the data on a page or the start-time. Continuous streams are +'end-time' encoded; the granulepos represents the point in time +immediately after the last data decoded from a page. Discontinuous +streams are 'start-time' encoded; the granulepos represents the point +in time of the first data decoded from the page.

    + +

    An Ogg stream type is declared continuous or discontinuous by its +codec. A given codec may support both continuous and discontinuous +operation so long as any given logical stream is continuous or +discontinuous for its entirety and the codec is able to ascertain (and +inform the Ogg layer) as to which after decoding the initial stream +header. The majority of codecs will always be continuous (such as +Vorbis) or discontinuous (such as Writ).

    + +

    Start- and end-time encoding do not affect multiplexing sort-order; +pages are still sorted by the absolute time a given granulepos maps to +regardless of whether that granulepos represents start- or +end-time.

    + +

    Multiplex/Demultiplex Division of Labor

    + +

    The Ogg multiplex/demultiplex layer provides mechanisms for encoding +raw packets into Ogg pages, decoding Ogg pages back into the original +codec packets, determining the logical structure of an Ogg stream, and +navigating through and synchronizing with an Ogg stream at a desired +stream location. Strict multiplex/demultiplex operations are entirely +in the Ogg domain and require no intervention from codecs.

    + +

    Implementation of more complex operations does require codec +knowledge, however. Unlike other framing systems, Ogg maintains +strict separation between framing and the framed bitstream data; Ogg +does not replicate codec-specific information in the page/framing +data, nor does Ogg blur the line between framing and stream +data/metadata. Because Ogg is fully data-agnostic toward the data it +frames, operations which require specifics of bitstream data (such as +'seek to key frame') also require interaction with the codec layer +(because, in this example, the Ogg layer is not aware of the concept +of key frames). This is different from systems that blur the +separation between framing and stream data in order to simplify the +separation of code. The Ogg system purposely keeps the distinction in +data simple so that later codec innovations are not constrained by +framing design.

    + +

    For this reason, however, complex seeking operations require +interaction with the codecs in order to decode the granule position of +a given stream type back to absolute time or in order to find +'decodable points' such as key frames in video.

    + +

    Unsorted Discussion Points

    + +

    flushes around key frames? RFC suggestion: repaginating or building a +stream this way is nice but not required

    Ogg bitstream overview

    + +

    This document serves as starting point for understanding the design +and implementation of the Ogg container format. If you're new to Ogg +or merely want a high-level technical overview, start reading here. +Other documents linked from the index page +give distilled technical descriptions and references of the container +mechanisms. This document is intended to aid understanding. + +

    Container format design points

    + +

    Ogg is intended to be a simplest-possible container, concerned only +with framing, ordering, and interleave. It can be used as a stream delivery +mechanism, for media file storage, or as a building block toward +implementing a more complex, non-linear container (for example, see +the Skeleton or Annodex/CMML). + +

    The Ogg container is not intended to be a monolithic +'kitchen-sink'. It exists only to frame and deliver in-order stream +data and as such is vastly simpler than most other containers. +Elementary and multiplexed streams are both constructed entirely from a +single building block (an Ogg page) comprised of eight fields +totalling twenty-eight bytes (the page header) a list of packet lengths +(up to 255 bytes) and payload data (up to 65025 bytes). The structure +of every page is the same. There are no optional fields or alternate +encodings. + +

    Stream and media metadata is contained in Ogg and not built into +the Ogg container itself. Metadata is thus compartmentalized and +layered rather than part of a monolithic design, an especially good +idea as no two groups seem able to agree on what a complete or +complete-enough metadata set should be. In this way, the container and +container implementation are isolated from unnecessary metadata design +flux. + +

    Streaming

    + +

    The Ogg container is primarily a streaming format, +encapsulating chronological, time-linear mixed media into a single +delivery stream or file. The design is such that an application can +always encode and/or decode all features of a bitstream in one pass +with no seeking and minimal buffering. Seeking to provide optimized +encoding (such as two-pass encoding) or interactive decoding (such as +scrubbing or instant replay) is not disallowed or discouraged, however +no container feature requires nonlinear access of the bitstream. + +

    Variable Bit Rate, Variable Payload Size

    + +

    Ogg is designed to contain any size data payload with bounded, +predictable efficiency. Ogg packets have no maximum size and a +zero-byte minimum size. There is no restriction on size changes from +packet to packet. Variable size packets do not require the use of any +optional or additional container features. There is no optimal +suggested packet size, though special consideration was paid to make +sure 50-200 byte packets were no less efficient than larger packet +sizes. The original design criteria was a 2% overhead at 50 byte +packets, dropping to a maximum working overhead of 1% with larger +packets, and a typical working overhead of .5-.7% for most practical +uses. + +

    Simple pagination

    + +

    Ogg is a byte-aligned container with no context-dependent, optional +or variable-length fields. Ogg requires no repacking of codec data. +The page structure is written out in-line as packet data is submitted +to the streaming abstraction. In addition, it is possible to +implement both Ogg mux and demux as MT-hot zero-copy abstractions (as +is done in the Tremor sourcebase). + +

    Capture

    + +

    Ogg is designed for efficient and immediate stream capture with +high confidence. Although packets have no size limit in Ogg, pages +are a maximum of just under 64kB meaning that any Ogg stream can be +captured with confidence after seeing 128kB of data or less [worst +case; typical figure is 6kB] from any random starting point in the +stream. + +

    Seeking

    + +

    Ogg implements simple coarse- and fine-grained seeking by design. + +

    Coarse seeking may be performed by simply 'moving the tone arm' to a +new position and 'dropping the needle'. Rapid capture with +accompanying timecode from any location in an Ogg file is guaranteed +by the stream design. From the acquisition of the first timecode, +all data needed to play back from that time code forward is ahead of +the stream cursor. + +

    Ogg implements full sample-granularity seeking using an +interpolated bisection search built on the capture and timecode +mechanisms used by coarse seeking. As above, once a search finds +the desired timecode, all data needed to play back from that time code +forward is ahead of the stream cursor. + +

    Both coarse and fine seeking use the page structure and sequencing +inherent to the Ogg format. All Ogg streams are fully seekable from +creation; seekability is unaffected by truncation or missing data, and +is tolerant of gross corruption. Seek operations are neither 'fuzzy' nor +heuristic. + +

    Seeking without use of an index is a major point of the Ogg +design. There two primary reasons why Ogg transport forgoes an index: + +

      + +
    1. An index is only marginally useful in Ogg for the complexity +added; it adds no new functionality and seldom improves performance +noticeably. Empirical testing shows that indexless interpolation +search does not require many more seeks in practice than using an +index would. + +
    2. 'Optional' indexes encourage lazy implementations that can seek +only when indexes are present, or that implement indexless seeking +only by building an internal index after reading the entire file +beginning to end. This has been the fate of other containers that +specify optional indexing. + +
    + +

    In addition, it must be possible to create an Ogg stream in a +single pass. Although an optional index can simply be tacked on the +end of the created stream, some software groups object to +end-positioned indexes and claim to be unwilling to support indexes +not located at the stream beginning. + +

    All this said, it's become clear that an optional index is a +demanded feature. For this reason, the OggSkeleton now defines a +proposed index. + +

    Simple multiplexing

    + +

    Ogg multiplexes streams by interleaving pages from multiple elementary streams into a +multiplexed stream in time order. The multiplexed pages are not +altered. Muxing an Ogg AV stream out of separate audio, +video and data streams is akin to shuffling several decks of cards +together into a single deck; the cards themselves remain unchanged. +Demultiplexing is similarly simple (as the cards are marked). + +

    The goal of this design is to make the mux/demux operation as +trivial as possible to allow live streaming systems to build and +rebuild streams on the fly with minimal CPU usage and no additional +storage or latency requirements. + +

    Continuous and Discontinuous Media

    + +

    Ogg streams belong to one of two categories, "Continuous" streams and +"Discontinuous" streams. + +

    A stream that provides a gapless, time-continuous media type with a +fine-grained timebase is considered to be 'Continuous'. A continuous +stream should never be starved of data. Examples of continuous data +types include broadcast audio and video. + +

    A stream that delivers data in a potentially irregular pattern or +with widely spaced timing gaps is considered to be 'Discontinuous'. A +discontinuous stream may be best thought of as data representing +scattered events; although they happen in order, they are typically +unconnected data often located far apart. One example of a +discontinuous stream types would be captioning such as Ogg Kate. Although it's +possible to design captions as a continuous stream type, it's most +natural to think of captions as widely spaced pieces of text with +little happening between. + +

    The fundamental reason for distinction between continuous and +discontinuous streams concerns buffering. + +

    Buffering

    + +

    A continuous stream is, by definition, gapless. Ogg buffering is based +on the simple premise of never allowing an active continuous stream +to starve for data during decode; buffering works ahead until all +continuous streams in a physical stream have data ready and no further. + +

    Discontinuous stream data is not assumed to be predictable. The +buffering design takes discontinuous data 'as it comes' rather than +working ahead to look for future discontinuous data for a potentially +unbounded period. Thus, the buffering process makes no attempt to fill +discontinuous stream buffers; their pages simply 'fall out' of the +stream when continuous streams are handled properly. + +

    Buffering requirements in this design need not be explicitly +declared or managed in the encoded stream. The decoder simply reads as +much data as is necessary to keep all continuous stream types gapless +and no more, with discontinuous data processed as it arrives in the +continuous data. Buffering is implicitly optimal for the given +stream. Because all pages of all data types are stamped with absolute +timing information within the stream, inter-stream synchronization +timing is always maintained without the need for explicitly declared +buffer-ahead hinting. + +

    Codec metadata

    + +

    Ogg does not replicate codec-specific metadata into the mux layer +in an attempt to make the mux and codec layer implementations 'fully +separable'. Things like specific timebase, keyframing strategy, frame +duration, etc, do not appear in the Ogg container. The mux layer is, +instead, expected to query a codec through a centralized interface, +left to the implementation, for this data when it is needed. + +

    Though modern design wisdom usually prefers to predict all possible +needs of current and future codecs then embed these dependencies and +the required metadata into the container itself, this strategy +increases container specification complexity, fragility, and rigidity. +The mux and codec code becomes more independent, but the +specifications become logically less independent. A codec can't do +what a container hasn't already provided for. Novel codecs are harder +to support, and you can do fewer useful things with the ones you've +already got (eg, try to make a good splitter without using any codecs. +Such a splitter is limited to splitting at keyframes only, or building +yet another new mechanism into the container layer to mark what frames +to skip displaying). + +

    Ogg's design goes the opposite direction, where the specification +is to be as simple, easy to understand, and 'proofed' against novel +codecs as possible. When an Ogg mux layer requires codec-specific +information, it queries the codec (or a codec stub). This trades a +more complex implementation for a simpler, more flexible +specification. + +

    Stream structure metadata

    + +

    The Ogg container itself does not define a metadata system for +declaring the structure and interrelations between multiple media +types in a muxed stream. That is, the Ogg container itself does not +specify data like 'which steam is the subtitle stream?' or 'which +video stream is the primary angle?'. This metadata still exists, but +is stored by the Ogg container rather than being built into the Ogg +container itself. Xiph specifies the 'Skeleton' metadata format for Ogg +streams, but this decoupling of container and stream structure +metadata means it is possible to use Ogg with any metadata +specification without altering the container itself, or without stream +structure metadata at all. + +

    Frame accurate absolute position

    + +

    Every Ogg page is stamped with a 64 bit 'granule position' that +serves as an absolute timestamp for mux and seeking. A few nifty +little tricks are usually also embedded in the granpos state, but +we'll leave those aside for the moment (strictly speaking, they're +part of each codec's mapping, not Ogg). + +

    As previously mentioned above, granule positions are mapped into +absolute timestamps by the codec, rather than being a hard timestamp. +This allows maximally efficient use of the available 64 bits to +address every sample/frame position without approximation while +supporting new and previously unknown timebase encodings without +needing to extend or update the mux layer. When a codec needs a novel +timebase, it simply brings the code for that mapping along with it. +This is not a theoretical curiosity; new, wholly novel timebases were +deployed with the adoption of both Theora and Dirac. "Rolling INTRA" +(keyframeless video) also benefits from novel use of the granule +position. + +

    Ogg stream arrangement

    + +

    Packets, pages, and bitstreams

    + +

    Ogg codecs place raw compressed data into packets. +Packets are octet payloads containing the data needed for a single +decompressed unit, eg, one video frame. Packets have no maximum size +and may be zero length. They do not generally have any framing +information; strung together, the unframed packets form a logical +bitstream of codec data with no internal landmarks. + +

    + + +

    Packets of raw codec data are not typically internally framed. + When they are strung together into a stream without any container to + provide framing, they lose their individual boundaries. Seek and + capture are not possible within an unframed stream, and for many + codecs with variable length payloads and/or early-packet termination + (such as Vorbis), it may become impossible to recover the original + frame boundaries even if the stream is scanned linearly from + beginning to end. + +

    + +

    Logical bitstream packets are grouped and framed into Ogg pages +along with a unique stream serial number to produce a +physical bitstream. An elementary stream is a +physical bitstream containing only a single logical bitstream. Each +page is a self contained entity, although a packet may be split and +encoded across one or more pages. The page decode mechanism is +designed to recognize, verify and handle single pages at a time from +the overall bitstream. + +

    + + +

    The primary purpose of a container is to provide framing for raw + packets, marking the packet boundaries so the exact packets can be + retrieved for decode later. The container also provides secondary + functions such as capture, timestamping, sequencing, stream + identification and so on. Not all of these functions are represented in the diagram. + +

    In the Ogg container, pages do not necessarily contain + integer numbers of packets. Packets may span across page boundaries + or even multiple pages. This is necessary as pages have a maximum + possible size in order to provide capture guarantees, but packet + size is unbounded. +

    + + +

    Ogg Bitstream Framing specifies +the page format of an Ogg bitstream, the packet coding process +and elementary bitstreams in detail. + +

    Multiplexed bitstreams

    + +

    Multiple logical/elementary bitstreams can be combined into a single +multiplexed bitstream by interleaving whole pages from each +contributing elementary stream in time order. The result is a single +physical stream that multiplexes and frames multiple logical streams. +Each logical stream is identified by the unique stream serial number +stamped in its pages. A physical stream may include a 'meta-header' +(such as the Ogg Skeleton) comprising its +own Ogg page at the beginning of the physical stream. A decoder +recovers the original logical/elementary bitstreams out of the +physical bitstream by taking the pages in order from the physical +bitstream and redirecting them into the appropriate logical decoding +entity. + +

    + + +

    Multiple media types are mutliplexed into a single Ogg stream by +interleaving the pages from each elementary physical stream. + +

    + +

    Ogg Bitstream Multiplexing specifies +proper multiplexing of an Ogg bitstream in detail. + +

    Chaining

    + +

    Multiple Ogg physical bitstreams may be concatenated into a single new +stream; this is chaining. The bitstreams do not overlap; the +final page of a given logical bitstream is immediately followed by the +initial page of the next.

    + +

    Each logical bitstream in a chain must have a unique serial number +within the scope of the full physical bitstream, not only within a +particular link or segment of the chain.

    + +

    Continuous and discontinuous streams

    + +

    Within Ogg, each stream must be declared (by the codec) to be +continuous- or discontinuous-time. Most codecs treat all streams they +use as either inherently continuous- or discontinuous-time, although +this is not a requirement. A codec may, as part of its mapping, choose +according to data in the initial header. + +

    Continuous-time pages are stamped by end-time, discontinuous pages +are stamped by begin-time. Pages in a multiplexed stream are +interleaved in order of the time stamp regardless of stream type. +Both continuous and discontinuous logical streams are used to seek +within a physical stream, however only continuous streams are used to +determine buffering depth; because discontinuous streams are stamped +by start time, they will always 'fall out' at the proper time when +buffering the continuous streams. See 'Examples' for an illustration +of the buffering mechanism. + +

    Multiplexing Requirements

    + +

    Multiplexing requirements within Ogg are straightforward. When +constructing a single-link (unchained) physical bitstream consisting +of multiple elementary streams: + +

      + +

    1. The initial header for each stream appears in sequence, each +header on a single page. All initial headers must appear with no +intervening data (no auxiliary header pages or packets, no data pages +or packets). Order of the initial headers is unspecified. The +'beginning of stream' flag is set on each initial header. + +

    2. All auxiliary headers for all streams must follow. Order +is unspecified. The final auxiliary header of each stream must flush +its page. + +

    3. Data pages for each stream follow, interleaved in time order. + +

    4. The final page of each stream sets the 'end of stream' flag. +Unlike initial pages, terminal pages for the logical bitstreams need +not occur contiguously; indeed it may not be possible for them to do so. +

    + +

    Each grouped bitstream must have a unique serial number within the +scope of the physical bitstream.

    + +

    chaining and multiplexing

    Multiplexed and/or unmultiplexed bitstreams may be chained +consecutively. Such a physical bitstream obeys all the rules of both +chained and multiplexed streams. Each link, when unchained, must +stand on its own as a valid physical bitstream. Chained streams do +not mix or interleave; a new segment may not begin until all streams +in the preceding segment have terminated.

    + +

    Codec Mapping Requirements

    + +

    Each codec is allowed some freedom in deciding how its logical +bitstream is encapsulated into an Ogg bitstream (even if it is a +trivial mapping, eg, 'plop the packets in and go'). This is the +codec's mapping. Ogg imposes a few mapping requirements +on any codec. + +

      + +

    1. The framing specification defines +'beginning of stream' and 'end of stream' page markers via a header +flag (it is possible for a stream to consist of a single page). A +correct stream always consists of an integer number of pages, an easy +requirement given the variable size nature of pages.

      + +

    2. The first page of an elementary Ogg bitstream consists of a single, +small 'initial header' packet that must include sufficient information +to identify the exact CODEC type. From this initial header, the codec +must also be able to determine its timebase and whether or not it is a +continuous- or discontinuous-time stream. The initial header must fit +on a single page. If a codec makes use of auxiliary headers (for +example, Vorbis uses two auxiliary headers), these headers must follow +the initial header immediately. The last header finishes its page; +data begins on a fresh page. + +

      As an example, Ogg Vorbis places the name and revision of the +Vorbis CODEC, the audio rate and the audio quality into this initial +header. Vorbis comments and detailed codec setup appears in the larger +auxiliary headers.

      + +

    3. Granule positions must be translatable to an exact absolute +time value. As described above, the mux layer is permitted to query a +codec or codec stub plugin to perform this mapping. It is not +necessary for an absolute time to be mappable into a single unique +granule position value. + +

    4. Codecs are not required to use a fixed duration-per-packet (for +example, Vorbis does not). the mux layer is permitted to query a +codec or codec stub plugin for the time duration of a packet. + +

    5. Although an absolute time need not be translatable to a unique +granule position, a codec must be able to determine the unique granule +position of the current packet using the granule position of a +preceding packet. + +

    6. Packets and pages must be arranged in ascending +granule-position and time order. + +

    + +

    Examples

    + +[More to come shortly; this section is currently being revised and expanded] + +

    Below, we present an example of a multiplexed and chained bitstream:

    + +

    stream

    + +

    In this example, we see pages from five total logical bitstreams +multiplexed into a physical bitstream. Note the following +characteristics:

    + +
      +
    1. Multiplexed bitstreams in a given link begin together; all of the +initial pages must appear before any data pages. When concurrently +multiplexed groups are chained, the new group does not begin until all +the bitstreams in the previous group have terminated.
      2. + +
    2. The ordering of pages of concurrently multiplexed bitstreams is +goverened by timestamp (not shown here); there is no regular +interleaving order. Pages within a logical bitstream appear in +sequence order.

Introduction + + The Ogg bitstream format has been developed as a part of a larger + project aimed at creating a set of components for the coding and + decoding of multimedia content (codecs) which are to be freely + available and freely re-implementable, both in software and in + hardware for the computing community at large, including the Internet + community. It is the intention of the Ogg developers represented by + Xiph.Org that it be usable without intellectual property concerns. + + This document describes the Ogg bitstream format and how to use it to + encapsulate one or several media bitstreams created by one or several + encoders. The Ogg transport bitstream is designed to provide + framing, error protection and seeking structure for higher-level + codec streams that consist of raw, unencapsulated data packets, such + as the Vorbis audio codec or the upcoming Tarkin and Theora video + codecs. It is capable of interleaving different binary media and + other time-continuous data streams that are prepared by an encoder as + a sequence of data packets. Ogg provides enough information to + properly separate data back into such encoder created data packets at + the original packet boundaries without relying on decoding to find + packet boundaries. + + Please note that the MIME type application/ogg has been registered + with the IANA [1]. + +2. Definitions + + For describing the Ogg encapsulation process, a set of terms will be + used whose meaning needs to be well understood. Therefore, some of + the most fundamental terms are defined now before we start with the + description of the requirements for a generic media stream + encapsulation format, the process of encapsulation, and the concrete + format of the Ogg bitstream. See the Appendix for a more complete + glossary. + + The result of an Ogg encapsulation is called the "Physical (Ogg) + Bitstream". It encapsulates one or several encoder-created + bitstreams, which are called "Logical Bitstreams". A logical + bitstream, provided to the Ogg encapsulation process, has a + structure, i.e., it is split up into a sequence of so-called + "Packets". The packets are created by the encoder of that logical + bitstream and represent meaningful entities for that encoder only + (e.g., an uncompressed stream may use video frames as packets). They + do not contain boundary information - strung together they appear to + be streams of random bytes with no landmarks. + + + + + +Pfeiffer Informational [Page 2] + +RFC 3533 OGG May 2003 + + + Please note that the term "packet" is not used in this document to + signify entities for transport over a network. + +3. Requirements for a generic encapsulation format + + The design idea behind Ogg was to provide a generic, linear media + transport format to enable both file-based storage and stream-based + transmission of one or several interleaved media streams independent + of the encoding format of the media data. Such an encapsulation + format needs to provide: + + o framing for logical bitstreams. + + o interleaving of different logical bitstreams. + + o detection of corruption. + + o recapture after a parsing error. + + o position landmarks for direct random access of arbitrary positions + in the bitstream. + + o streaming capability (i.e., no seeking is needed to build a 100% + complete bitstream). + + o small overhead (i.e., use no more than approximately 1-2% of + bitstream bandwidth for packet boundary marking, high-level + framing, sync and seeking). + + o simplicity to enable fast parsing. + + o simple concatenation mechanism of several physical bitstreams. + + All of these design considerations have been taken into consideration + for Ogg. Ogg supports framing and interleaving of logical + bitstreams, seeking landmarks, detection of corruption, and stream + resynchronisation after a parsing error with no more than + approximately 1-2% overhead. It is a generic framework to perform + encapsulation of time-continuous bitstreams. It does not know any + specifics about the codec data that it encapsulates and is thus + independent of any media codec. + +4. The Ogg bitstream format + + A physical Ogg bitstream consists of multiple logical bitstreams + interleaved in so-called "Pages". Whole pages are taken in order + from multiple logical bitstreams multiplexed at the page level. The + logical bitstreams are identified by a unique serial number in the + + + +Pfeiffer Informational [Page 3] + +RFC 3533 OGG May 2003 + + + header of each page of the physical bitstream. This unique serial + number is created randomly and does not have any connection to the + content or encoder of the logical bitstream it represents. Pages of + all logical bitstreams are concurrently interleaved, but they need + not be in a regular order - they are only required to be consecutive + within the logical bitstream. Ogg demultiplexing reconstructs the + original logical bitstreams from the physical bitstream by taking the + pages in order from the physical bitstream and redirecting them into + the appropriate logical decoding entity. + + Each Ogg page contains only one type of data as it belongs to one + logical bitstream only. Pages are of variable size and have a page + header containing encapsulation and error recovery information. Each + logical bitstream in a physical Ogg bitstream starts with a special + start page (bos=beginning of stream) and ends with a special page + (eos=end of stream). + + The bos page contains information to uniquely identify the codec type + and MAY contain information to set up the decoding process. The bos + page SHOULD also contain information about the encoded media - for + example, for audio, it should contain the sample rate and number of + channels. By convention, the first bytes of the bos page contain + magic data that uniquely identifies the required codec. It is the + responsibility of anyone fielding a new codec to make sure it is + possible to reliably distinguish his/her codec from all other codecs + in use. There is no fixed way to detect the end of the codec- + identifying marker. The format of the bos page is dependent on the + codec and therefore MUST be given in the encapsulation specification + of that logical bitstream type. Ogg also allows but does not require + secondary header packets after the bos page for logical bitstreams + and these must also precede any data packets in any logical + bitstream. These subsequent header packets are framed into an + integral number of pages, which will not contain any data packets. + So, a physical bitstream begins with the bos pages of all logical + bitstreams containing one initial header packet per page, followed by + the subsidiary header packets of all streams, followed by pages + containing data packets. + + The encapsulation specification for one or more logical bitstreams is + called a "media mapping". An example for a media mapping is "Ogg + Vorbis", which uses the Ogg framework to encapsulate Vorbis-encoded + audio data for stream-based storage (such as files) and transport + (such as TCP streams or pipes). Ogg Vorbis provides the name and + revision of the Vorbis codec, the audio rate and the audio quality on + the Ogg Vorbis bos page. It also uses two additional header pages + per logical bitstream. The Ogg Vorbis bos page starts with the byte + 0x01, followed by "vorbis" (a total of 7 bytes of identifier). + + + + +Pfeiffer Informational [Page 4] + +RFC 3533 OGG May 2003 + + + Ogg knows two types of multiplexing: concurrent multiplexing (so- + called "Grouping") and sequential multiplexing (so-called + "Chaining"). Grouping defines how to interleave several logical + bitstreams page-wise in the same physical bitstream. Grouping is for + example needed for interleaving a video stream with several + synchronised audio tracks using different codecs in different logical + bitstreams. Chaining on the other hand, is defined to provide a + simple mechanism to concatenate physical Ogg bitstreams, as is often + needed for streaming applications. + + In grouping, all bos pages of all logical bitstreams MUST appear + together at the beginning of the Ogg bitstream. The media mapping + specifies the order of the initial pages. For example, the grouping + of a specific Ogg video and Ogg audio bitstream may specify that the + physical bitstream MUST begin with the bos page of the logical video + bitstream, followed by the bos page of the audio bitstream. Unlike + bos pages, eos pages for the logical bitstreams need not all occur + contiguously. Eos pages may be 'nil' pages, that is, pages + containing no content but simply a page header with position + information and the eos flag set in the page header. Each grouped + logical bitstream MUST have a unique serial number within the scope + of the physical bitstream. + + In chaining, complete logical bitstreams are concatenated. The + bitstreams do not overlap, i.e., the eos page of a given logical + bitstream is immediately followed by the bos page of the next. Each + chained logical bitstream MUST have a unique serial number within the + scope of the physical bitstream. + + It is possible to consecutively chain groups of concurrently + multiplexed bitstreams. The groups, when unchained, MUST stand on + their own as a valid concurrently multiplexed bitstream. The + following diagram shows a schematic example of such a physical + bitstream that obeys all the rules of both grouped and chained + multiplexed bitstreams. + + physical bitstream with pages of + different logical bitstreams grouped and chained + ------------------------------------------------------------- + |*A*|*B*|*C*|A|A|C|B|A|B|#A#|C|...|B|C|#B#|#C#|*D*|D|...|#D#| + ------------------------------------------------------------- + bos bos bos eos eos eos bos eos + + In this example, there are two chained physical bitstreams, the first + of which is a grouped stream of three logical bitstreams A, B, and C. + The second physical bitstream is chained after the end of the grouped + bitstream, which ends after the last eos page of all its grouped + logical bitstreams. As can be seen, grouped bitstreams begin + + + +Pfeiffer Informational [Page 5] + +RFC 3533 OGG May 2003 + + + together - all of the bos pages MUST appear before any data pages. + It can also be seen that pages of concurrently multiplexed bitstreams + need not conform to a regular order. And it can be seen that a + grouped bitstream can end long before the other bitstreams in the + group end. + + Ogg does not know any specifics about the codec data except that each + logical bitstream belongs to a different codec, the data from the + codec comes in order and has position markers (so-called "Granule + positions"). Ogg does not have a concept of 'time': it only knows + about sequentially increasing, unitless position markers. An + application can only get temporal information through higher layers + which have access to the codec APIs to assign and convert granule + positions or time. + + A specific definition of a media mapping using Ogg may put further + constraints on its specific use of the Ogg bitstream format. For + example, a specific media mapping may require that all the eos pages + for all grouped bitstreams need to appear in direct sequence. An + example for a media mapping is the specification of "Ogg Vorbis". + Another example is the upcoming "Ogg Theora" specification which + encapsulates Theora-encoded video data and usually comes multiplexed + with a Vorbis stream for an Ogg containing synchronised audio and + video. As Ogg does not specify temporal relationships between the + encapsulated concurrently multiplexed bitstreams, the temporal + synchronisation between the audio and video stream will be specified + in this media mapping. To enable streaming, pages from various + logical bitstreams will typically be interleaved in chronological + order. + +5. The encapsulation process + + The process of multiplexing different logical bitstreams happens at + the level of pages as described above. The bitstreams provided by + encoders are however handed over to Ogg as so-called "Packets" with + packet boundaries dependent on the encoding format. The process of + encapsulating packets into pages will be described now. + + From Ogg's perspective, packets can be of any arbitrary size. A + specific media mapping will define how to group or break up packets + from a specific media encoder. As Ogg pages have a maximum size of + about 64 kBytes, sometimes a packet has to be distributed over + several pages. To simplify that process, Ogg divides each packet + into 255 byte long chunks plus a final shorter chunk. These chunks + are called "Ogg Segments". They are only a logical construct and do + not have a header for themselves. + + + + + +Pfeiffer Informational [Page 6] + +RFC 3533 OGG May 2003 + + + A group of contiguous segments is wrapped into a variable length page + preceded by a header. A segment table in the page header tells about + the "Lacing values" (sizes) of the segments included in the page. A + flag in the page header tells whether a page contains a packet + continued from a previous page. Note that a lacing value of 255 + implies that a second lacing value follows in the packet, and a value + of less than 255 marks the end of the packet after that many + additional bytes. A packet of 255 bytes (or a multiple of 255 bytes) + is terminated by a lacing value of 0. Note also that a 'nil' (zero + length) packet is not an error; it consists of nothing more than a + lacing value of zero in the header. + + The encoding is optimized for speed and the expected case of the + majority of packets being between 50 and 200 bytes large. This is a + design justification rather than a recommendation. This encoding + both avoids imposing a maximum packet size as well as imposing + minimum overhead on small packets. In contrast, e.g., simply using + two bytes at the head of every packet and having a max packet size of + 32 kBytes would always penalize small packets (< 255 bytes, the + typical case) with twice the segmentation overhead. Using the lacing + values as suggested, small packets see the minimum possible byte- + aligned overhead (1 byte) and large packets (>512 bytes) see a fairly + constant ~0.5% overhead on encoding space. + + + + + + + + + + + + + + + + + + + + + + + + + + + + +Pfeiffer Informational [Page 7] + +RFC 3533 OGG May 2003 + + + The following diagram shows a schematic example of a media mapping + using Ogg and grouped logical bitstreams: + + logical bitstream with packet boundaries + ----------------------------------------------------------------- + > | packet_1 | packet_2 | packet_3 | < + ----------------------------------------------------------------- + + |segmentation (logically only) + v + + packet_1 (5 segments) packet_2 (4 segs) p_3 (2 segs) + ------------------------------ -------------------- ------------ + .. |seg_1|seg_2|seg_3|seg_4|s_5 | |seg_1|seg_2|seg_3|| |seg_1|s_2 | .. + ------------------------------ -------------------- ------------ + + | page encapsulation + v + + page_1 (packet_1 data) page_2 (pket_1 data) page_3 (packet_2 data) +------------------------ ---------------- ------------------------ +|H|------------------- | |H|----------- | |H|------------------- | +|D||seg_1|seg_2|seg_3| | |D|seg_4|s_5 | | |D||seg_1|seg_2|seg_3| | ... +|R|------------------- | |R|----------- | |R|------------------- | +------------------------ ---------------- ------------------------ + + | +pages of | +other --------| | +logical ------- +bitstreams | MUX | + ------- + | + v + + page_1 page_2 page_3 + ------ ------ ------- ----- ------- + ... || | || | || | || | || | ... + ------ ------ ------- ----- ------- + physical Ogg bitstream + + In this example we take a snapshot of the encapsulation process of + one logical bitstream. We can see part of that bitstream's + subdivision into packets as provided by the codec. The Ogg + encapsulation process chops up the packets into segments. The + packets in this example are rather large such that packet_1 is split + into 5 segments - 4 segments with 255 bytes and a final smaller one. + Packet_2 is split into 4 segments - 3 segments with 255 bytes and a + + + +Pfeiffer Informational [Page 8] + +RFC 3533 OGG May 2003 + + + final very small one - and packet_3 is split into two segments. The + encapsulation process then creates pages, which are quite small in + this example. Page_1 consists of the first three segments of + packet_1, page_2 contains the remaining 2 segments from packet_1, and + page_3 contains the first three pages of packet_2. Finally, this + logical bitstream is multiplexed into a physical Ogg bitstream with + pages of other logical bitstreams. + +6. The Ogg page format + + A physical Ogg bitstream consists of a sequence of concatenated + pages. Pages are of variable size, usually 4-8 kB, maximum 65307 + bytes. A page header contains all the information needed to + demultiplex the logical bitstreams out of the physical bitstream and + to perform basic error recovery and landmarks for seeking. Each page + is a self-contained entity such that the page decode mechanism can + recognize, verify, and handle single pages at a time without + requiring the overall bitstream. + + The Ogg page header has the following format: + + 0 1 2 3 + 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1| Byte ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +| capture_pattern: Magic number for page start "OggS" | 0-3 ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +| version | header_type | granule_position | 4-7 ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +| | 8-11 ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +| | bitstream_serial_number | 12-15 ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +| | page_sequence_number | 16-19 ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +| | CRC_checksum | 20-23 ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +| |page_segments | segment_table | 24-27 ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ +| ... | 28- ++-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + + The LSb (least significant bit) comes first in the Bytes.

For a video stream it MAY contain the total number of video + + + +Pfeiffer Informational [Page 10] + +RFC 3533 OGG May 2003 + + + frames encoded after this page. This is a hint for the decoder + and gives it some timing and position information. Its meaning is + dependent on the codec for that logical bitstream and specified in + a specific media mapping. A special value of -1 (in two's + complement) indicates that no packets finish on this page. + + 5. bitstream_serial_number: a 4 Byte field containing the unique + serial number by which the logical bitstream is identified. + + 6. page_sequence_number: a 4 Byte field containing the sequence + number of the page so the decoder can identify page loss. This + sequence number is increasing on each logical bitstream + separately. + + 7. CRC_checksum: a 4 Byte field containing a 32 bit CRC checksum of + the page (including header with zero CRC field and page content). + The generator polynomial is 0x04c11db7. + + 8. number_page_segments: 1 Byte giving the number of segment entries + encoded in the segment table. + + 9. segment_table: number_page_segments Bytes containing the lacing + values of all segments in this page. Each Byte contains one + lacing value. + + The total header size in bytes is given by: + header_size = number_page_segments + 27 [Byte] + + The total page size in Bytes is given by: + page_size = header_size + sum(lacing_values: 1..number_page_segments) + [Byte] + +7. Security Considerations + + The Ogg encapsulation format is a container format and only + encapsulates content (such as Vorbis-encoded audio). It does not + provide for any generic encryption or signing of itself or its + contained content bitstreams.

Introduction + + This document describes media types for Ogg, a data encapsulation + format defined by the Xiph.Org Foundation for public use. Refer to + "Introduction" in [RFC3533] and "Overview" in [Ogg] for background + information on this container format. + + Binary data contained in Ogg, such as Vorbis and Theora, has + historically been interchanged using the application/ogg media type + as defined by [RFC3534]. This document obsoletes [RFC3534] and + defines three media types for different types of content in Ogg to + reflect this usage in the IANA media type registry, to foster + interoperability by defining underspecified aspects, and to provide + general security considerations. + + The Ogg container format is known to contain [Theora] or [Dirac] + video, [Speex] (narrow-band and wide-band) speech, [Vorbis] or [FLAC] + audio, and [CMML] timed text/metadata. As Ogg encapsulates binary + data, it is possible to include any other type of video, audio, + image, text, or, generally speaking, any time-continuously sampled + data. + + While raw packets from these data sources may be used directly by + transport mechanisms that provide their own framing and packet- + separation mechanisms (such as UDP datagrams or RTP), Ogg is a + solution for stream based storage (such as files) and transport (such + as TCP streams or pipes). The media types defined in this document + are needed to correctly identify such content when it is served over + HTTP, included in multi-part documents, or used in other places where + media types [RFC2045] are used. + +2. Changes Since RFC 3534 + + o The type "application/ogg" is redefined. + + o The types "video/ogg" and "audio/ogg" are defined. + + o New file extensions are defined. + + o New Macintosh file type codes are defined. + + o The codecs parameter is defined for optional use. + + o The Ogg Skeleton extension becomes a recommended addition for + content served under the new types. + + + + + + +Goncalves, et al. Standards Track [Page 2] + +RFC 5334 Ogg Media Types September 2008 + + +3. Conformance and Document Conventions + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, [RFC2119] and + indicate requirement levels for compliant implementations. + Requirements apply to all implementations unless otherwise stated. + + An implementation is a software module that supports one of the media + types defined in this document. Software modules may support + multiple media types, but conformance is considered individually for + each type. + + Implementations that fail to satisfy one or more "MUST" requirements + are considered non-compliant. Implementations that satisfy all + "MUST" requirements, but fail to satisfy one or more "SHOULD" + requirements, are said to be "conditionally compliant". All other + implementations are "unconditionally compliant". + +4. Deployed Media Types and Compatibility + + The application/ogg media type has been used in an ad hoc fashion to + label and exchange multimedia content in Ogg containers. + + Use of the "application" top-level type for this kind of content is + known to be problematic, in particular since it obfuscates video and + audio content. This document thus defines the media types, + + o video/ogg + + o audio/ogg + + which are intended for common use and SHOULD be used when dealing + with video or audio content, respectively. This document also + obsoletes the [RFC3534] definition of application/ogg and marks it + for complex data (e.g., multitrack visual, audio, textual, and other + time-continuously sampled data), which is not clearly video or audio + data and thus not suited for either the video/ogg or audio/ogg types. + Refer to the following section for more details. + + An Ogg bitstream generally consists of one or more logical bitstreams + that each consist of a series of header and data pages packetising + time-continuous binary data [RFC3533]. The content types of the + logical bitstreams may be identified without decoding the header + pages of the logical bitstreams through use of a [Skeleton] + bitstream. Using Ogg Skeleton is REQUIRED for content served under + + + + + +Goncalves, et al. Standards Track [Page 3] + +RFC 5334 Ogg Media Types September 2008 + + + the application/ogg type and RECOMMENDED for video/ogg and audio/ogg, + as Skeleton contains identifiers to describe the different + encapsulated data. + + Furthermore, it is RECOMMENDED that implementations that identify a + logical bitstream that they cannot decode SHOULD ignore it, while + continuing to decode the ones they can. Such precaution ensures + backward and forward compatibility with existing and future data. + + These media types can optionally use the "codecs" parameter described + in [RFC4281]. Codecs encapsulated in Ogg require a text identifier + at the beginning of the first header page, hence a machine-readable + method to identify the encapsulated codecs would be through this + header. The following table illustrates how those header values map + into strings that are used in the "codecs" parameter when dealing + with Ogg media types. + + Codec Identifier | Codecs Parameter + ----------------------------------------------------------- + char[5]: 'BBCD\0' | dirac + char[5]: '\177FLAC' | flac + char[7]: '\x80theora' | theora + char[7]: '\x01vorbis' | vorbis + char[8]: 'CELT ' | celt + char[8]: 'CMML\0\0\0\0' | cmml + char[8]: '\213JNG\r\n\032\n' | jng + char[8]: '\x80kate\0\0\0' | kate + char[8]: 'OggMIDI\0' | midi + char[8]: '\212MNG\r\n\032\n' | mng + char[8]: 'PCM ' | pcm + char[8]: '\211PNG\r\n\032\n' | png + char[8]: 'Speex ' | speex + char[8]: 'YUV4MPEG' | yuv4mpeg + + An up-to-date version of this table is kept at Xiph.org (see + [Codecs]). + + Possible examples include: + + o application/ogg; codecs="theora, cmml, ecmascript" + + o video/ogg; codecs="theora, vorbis" + + o audio/ogg; codecs=speex + + + + + + + +Goncalves, et al. Standards Track [Page 4] + +RFC 5334 Ogg Media Types September 2008 + + +5. Relation between the Media Types + + As stated in the previous section, this document describes three + media types that are targeted at different data encapsulated in Ogg. + Since Ogg is capable of encapsulating any kind of data, the multiple + usage scenarios have revealed interoperability issues between + implementations when dealing with content served solely under the + application/ogg type. + + While this document does redefine the earlier definition of + application/ogg, this media type will continue to embrace the widest + net possible of content with the video/ogg and audio/ogg types being + smaller subsets of it. However, the video/ogg and audio/ogg types + take precedence in a subset of the usages, specifically when serving + multimedia content that is not complex enough to warrant the use of + application/ogg. Following this line of thought, the audio/ogg type + is an even smaller subset within video/ogg, as it is not intended to + refer to visual content. + + As such, the application/ogg type is the recommended choice to serve + content aimed at scientific and other applications that require + various multiplexed signals or streams of continuous data, with or + without scriptable control of content. For bitstreams containing + visual, timed text, and any other type of material that requires a + visual interface, but that is not complex enough to warrant serving + under application/ogg, the video/ogg type is recommended. In + situations where the Ogg bitstream predominantly contains audio data + (lyrics, metadata, or cover art notwithstanding), it is recommended + to use the audio/ogg type. + +6. Encoding Considerations + + Binary: The content consists of an unrestricted sequence of octets. + + Note: + + o Ogg encapsulated content is binary data and should be transmitted + in a suitable encoding without CR/LF conversion, 7-bit stripping, + etc.; base64 [RFC4648] is generally preferred for binary-to-text + encoding. + + o Media types described in this document are used for stream based + storage (such as files) and transport (such as TCP streams or + pipes); separate types are used to identify codecs such as in + real-time applications for the RTP payload formats of Theora + [ThRTP] video, Vorbis [RFC5215], or Speex [SpRTP] audio, as well + as for identification of encapsulated data within Ogg through + Skeleton. + + + +Goncalves, et al. Standards Track [Page 5] + +RFC 5334 Ogg Media Types September 2008 + + +7. Security Considerations + + Refer to [RFC3552] for a discussion of terminology used in this + section. + + The Ogg encapsulation format is a container and only a carrier of + content (such as audio, video, and displayable text data) with a very + rigid definition. This format in itself is not more vulnerable than + any other content framing mechanism. + + Ogg does not provide for any generic encryption or signing of itself + or its contained bitstreams. However, it encapsulates any kind of + binary content and is thus able to contain encrypted and signed + content data. It is also possible to add an external security + mechanism that encrypts or signs an Ogg bitstream and thus provides + content confidentiality and authenticity. + + As Ogg encapsulates binary data, it is possible to include executable + content in an Ogg bitstream. Implementations SHOULD NOT execute such + content without prior validation of its origin by the end-user. + + Issues may arise on applications that use Ogg for streaming or file + transfer in a networking scenario. In such cases, implementations + decoding Ogg and its encapsulated bitstreams have to ensure correct + handling of manipulated bitstreams, of buffer overflows, and similar + issues. + + It is also possible to author malicious Ogg bitstreams, which attempt + to call for an excessively large picture size, high sampling-rate + audio, etc. Implementations SHOULD protect themselves against this + kind of attack. + + Ogg has an extensible structure, so that it is theoretically possible + that metadata fields or media formats might be defined in the future + which might be used to induce particular actions on the part of the + recipient, thus presenting additional security risks. However, this + type of capability is currently not supported in the referenced + specification. + + Implementations may fail to implement a specific security model or + other means to prevent possibly dangerous operations. Such failure + might possibly be exploited to gain unauthorized access to a system + or sensitive information; such failure constitutes an unknown factor + and is thus considered out of the scope of this document. + + + + + + + +Goncalves, et al. Standards Track [Page 6] + +RFC 5334 Ogg Media Types September 2008 + + +8. Interoperability Considerations + + The Ogg container format is device-, platform-, and vendor-neutral + and has proved to be widely implementable across different computing + platforms through a wide range of encoders and decoders. A broadly + portable reference implementation [libogg] is available under the + revised (3-clause) BSD license, which is a Free Software license. + + The Xiph.Org Foundation has defined the specification, + interoperability, and conformance and conducts regular + interoperability testing. + + The use of the Ogg Skeleton extension has been confirmed to not cause + interoperability issues with existing implementations. Third parties + are, however, welcome to conduct their own testing. + +9.

    The Ogg Skeleton Metadata Bitstream

    + +

    Overview

    + +

    Ogg Skeleton provides structuring information for multitrack Ogg files. It is compatible with Ogg Theora and provides extra clues for synchronization and content negotiation such as language selection.

    + +

    Ogg is a generic container format for time-continuous data streams, enabling interleaving of several tracks of frame-wise encoded content in a time-multiplexed manner. As an example, an Ogg physical bitstream could encapsulate several tracks of video encoded in Theora and multiple tracks of audio encoded in Speex or Vorbis or FLAC at the same time. A player that decodes such a bitstream could then, for example, play one video channel as the main video playback, alpha-blend another one on top of it (e.g. a caption track), play a main Vorbis audio together with several FLAC audio tracks simultaneously (e.g. as sound effects), and provide a choice of Speex channels (e.g. providing commentary in different languages). Such a file is generally possible to create with Ogg, it is however not possible to generically parse such a file, seek on it, understand what codecs are contained in such a file, and dynamically handle and play back such content.

    + +

    Ogg does not know anything about the content it carries and leaves it to the media mapping of each codec to declare and describe itself. There is no meta information available at the Ogg level about the content tracks encapsulated within an Ogg physical bitstream. This is particularly a problem if you don't have all the decoder libraries available and just want to parse an Ogg file to find out what type of data it encapsulates (such as the "file" command under *nix to determine what file it is through magic numbers), or want to seek to a temporal offset without having to decode the data (such as on a Web server that just serves out Ogg files and parts thereof).

    + +

    Ogg Skeleton is being designed to overcome these problems. Ogg Skeleton is a logical bitstream within an Ogg stream that contains information about the other encapsulated logical bitstreams. For each logical bitstream it provides information such as its media type, and explains the way the granulepos field in Ogg pages is mapped to time.

    + +

    Ogg Skeleton is also designed to allow the creation of substreams from Ogg physical bitstreams that retain the original timing information. For example, when cutting out the segment between the 7th and the 59th second of an Ogg file, it would be nice to continue to start this cut out file with a playback time of 7 seconds and not of 0. This is of particular interest if you're streaming this file from a Web server after a query for a temporal subpart such as in http://example.com/video.ogv?t=7-59

    + +

    Specification

    + +

    How to describe the logical bitstreams within an Ogg container?

    + +

    The following information about a logical bitstream is of interest to contain as meta information in the Skeleton:

    +
      +
    • the serial number: it identifies a content track
      • +
    • the mime type: it identifies the content type
      • +
    • other generic name-value fields that can provide meta information such as the language of a track or the video height and width
      • +
    • the number of header packets: this informs a parser about the number of actual header packets in an Ogg logical bitstream
      • +
    • the granule rate: the granule rate represents the data rate in Hz at which content is sampled for the particular logical bitstream, allowing to map a granule position to time by calculating "granulepos / granulerate"
      • +
    • the preroll: the number of past content packets to take into account when decoding the current Ogg page, which is necessary for seeking (vorbis has generally 2, speex 3)
      • +
    • the granuleshift: the number of lower bits from the granulepos field that are used to provide position information for sub-seekable units (like the keyframe shift in theora)
      • +
    • a basetime: it provides a mapping for granule position 0 (for all logical bitstreams) to a playback time; an example use: most content in professional analog video creation actually starts at a time of 1 hour and thus adding this additional field allows them retain this mapping on digitizing their content
      • +
    • a UTC time: it provides a mapping for granule position 0 (for all logical bitstreams) to a real-world clock time allowing to remember e.g. the recording or broadcast time of some content
      • +
    + +

    How to allow the creation of substreams from an Ogg physical bitstream?

    + +

    When cutting out a subpart of an Ogg physical bitstream, the aim is to keep all the content pages intact (including the framing and granule positions) and just change some information in the Skeleton that allows reconstruction of the accurate time mapping. When remultiplexing such a bitstream, it is necessary to take into account all the different contained logical bitstreams. A given cut-in time maps to several different byte positions in the Ogg physical bitstream because each logical bitstream has its relevant information for that time at a different location. In addition, the resolution of each logical bitstream may not be high enough to accommodate for the given cut-in time and thus there may be some surplus information necessary to be remuxed into the new bitstream.

    + +

    The following information is necessary to be added to the Skeleton to allow a correct presentation of a subpart of an Ogg bitstream:

    +
      +
    • the presentation time: this is the actual cut-in time and all logical bitstreams are meant to start presenting from this time onwards, not from the time their data starts, which may be some time before that (because this time may have mapped right into the middle of a packet, or because the logical bitstream has a preroll or a keyframe shift)
      • +
    • the basegranule: this represents the granule number with which this logical bitstream starts in the remuxed stream and provides for each logical bitstream the accurate start time of its data stream; this information is necessary to allow correct decoding and timing of the first data packets contained in a logcial bitstream of a remuxed Ogg stream
      • +
    + +

    Ogg Skeleton version 3.0 Format Specification

    + +

    Adding the above information into an Ogg bitstream without breaking existing Ogg functionality and code requires the use of a logical bitstream for Ogg Skeleton. This logical bitstream may be ignored on decoding such that existing players can still continue to play back Ogg files that have a Skeleton bitstream. Skeleton enriches the Ogg bitstream to provide meta information about structure and content of the Ogg bitstream.

    + +

    The Skeleton logical bitstream starts with an ident header that contains information about all of the logical bitstreams and is mapped into the Skeleton bos page. The first 8 bytes provide the magic identifier "fishead\0". +After the fishead follows a set of secondary header packets, each of which contains information about one logical bitstream. These secondary header packets are identified by an 8 byte code of "fisbone\0". The Skeleton logical bitstream has no actual content packets. Its eos page is included into the stream before any data pages of the other logical bitstreams appear and contains a packet of length 0.

    + +

    The fishead ident header looks as follows:

    +
    +
+  0                   1                   2                   3

    The version fields provide version information for the Skeleton track, currently being 3.0 (the number having evolved within the Annodex project).

    + +

    Presentation time and basetime are specified as a rational number, the denominator providing the temporal resolution at which the time is given (e.g. to specify time in milliseconds, provide a denominator of 1000).

    + +

    The fisbone secondary header packet looks as follows:

    The mime type is provided as a message header field specified in the same way that HTTP header fields are given (e.g. "Content-Type: audio/vorbis"). Further meta information (such as language and screen size) are also included as message header fields. The offset to the message header fields at the beginning of a fisbone packet is included for forward compatibility - to allow further fields to be included into the packet without disrupting the message header field parsing.

    + +

    The granule rate is again given as a rational number in the same way that presentation time and basetime were provided above.

    + +

    A further restriction on how to encapsulate Skeleton into Ogg is proposed to allow for easier parsing:

    +
      +
    • there can only be one Skeleton logical bitstream in a Ogg bitstream
      • +

    +     + + +RAI +codec + + + +This document defines the Ogg encapsulation for the Opus interactive speech and + audio codec. +This allows data encoded in the Opus format to be stored in an Ogg logical + bitstream. + + +     + + +
    + +The IETF Opus codec is a low-latency audio codec optimized for both voice and + general-purpose audio. +See for technical details. +This document defines the encapsulation of Opus in a continuous, logical Ogg + bitstream . +Ogg encapsulation provides Opus with a long-term storage format supporting + all of the essential features, including metadata, fast and accurate seeking, + corruption detection, recapture after errors, low overhead, and the ability to + multiplex Opus with other codecs (including video) with minimal buffering. +It also provides a live streamable format, capable of delivery over a reliable + stream-oriented transport, without requiring all the data, or even the total + length of the data, up-front, in a form that is identical to the on-disk + storage format. + + +Ogg bitstreams are made up of a series of 'pages', each of which contains data + from one or more 'packets'. +Pages are the fundamental unit of multiplexing in an Ogg stream. +Each page is associated with a particular logical stream and contains a capture + pattern and checksum, flags to mark the beginning and end of the logical + stream, and a 'granule position' that represents an absolute position in the + stream, to aid seeking. +A single page can contain up to 65,025 octets of packet data from up to 255 + different packets. +Packets can be split arbitrarily across pages, and continued from one page to + the next (allowing packets much larger than would fit on a single page). +Each page contains 'lacing values' that indicate how the data is partitioned + into packets, allowing a demultiplexer (demuxer) to recover the packet + boundaries without examining the encoded data. +A packet is said to 'complete' on a page when the page contains the final + lacing value corresponding to that packet. + + +This encapsulation defines the contents of the packet data, including + the necessary headers, the organization of those packets into a logical + stream, and the interpretation of the codec-specific granule position field. +It does not attempt to describe or specify the existing Ogg container format. +Readers unfamiliar with the basic concepts mentioned above are encouraged to + review the details in . + + +
    + +
    + +The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", + "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in . + + +
    + +
    + +An Ogg Opus stream is organized as follows (see + for an example). + + +
    + +
    + + +There are two mandatory header packets. +The first packet in the logical Ogg bitstream MUST contain the identification + (ID) header, which uniquely identifies a stream as Opus audio. +The format of this header is defined in . +It is placed alone (without any other packet data) on the first page of + the logical Ogg bitstream, and completes on that page. +This page has its 'beginning of stream' flag set. + + +The second packet in the logical Ogg bitstream MUST contain the comment header, + which contains user-supplied metadata. +The format of this header is defined in . +It MAY span multiple pages, beginning on the second page of the logical + stream. +However many pages it spans, the comment header packet MUST finish the page on + which it completes. + + +All subsequent pages are audio data pages, and the Ogg packets they contain are + audio data packets. +Each audio data packet contains one Opus packet for each of N different + streams, where N is typically one for mono or stereo, but MAY be greater than + one for multichannel audio. +The value N is specified in the ID header (see + ), and is fixed over the entire length of the + logical Ogg bitstream. + + +The first (N - 1) Opus packets, if any, are packed one after another + into the Ogg packet, using the self-delimiting framing from Appendix B of + . +The remaining Opus packet is packed at the end of the Ogg packet using the + regular, undelimited framing from Section 3 of . +All of the Opus packets in a single Ogg packet MUST be constrained to have the + same duration. +An implementation of this specification SHOULD treat any Opus packet whose + duration is different from that of the first Opus packet in an Ogg packet as + if it were a malformed Opus packet with an invalid Table Of Contents (TOC) + sequence. + + +The TOC sequence at the beginning of each Opus packet indicates the coding + mode, audio bandwidth, channel count, duration (frame size), and number of + frames per packet, as described in Section 3.1 + of . +The coding mode is one of SILK, Hybrid, or Constrained Energy Lapped Transform + (CELT). +The combination of coding mode, audio bandwidth, and frame size is referred to + as the configuration of an Opus packet. + + +Packets are placed into Ogg pages in order until the end of stream. +Audio data packets might span page boundaries. +The first audio data page could have the 'continued packet' flag set + (indicating the first audio data packet is continued from a previous page) if, + for example, it was a live stream joined mid-broadcast, with the headers + pasted on the front. +If a page has the 'continued packet' flag set and one of the following + conditions is also true: + +the previous page with packet data does not end in a continued packet (does + not end with a lacing value of 255) OR +the page sequence numbers are not consecutive, + + then a demuxer MUST NOT attempt to decode the data for the first packet on the + page unless the demuxer has some special knowledge that would allow it to + interpret this data despite the missing pieces. +An implementation MUST treat a zero-octet audio data packet as if it were a + malformed Opus packet as described in + Section 3.4 of . + + +A logical stream ends with a page with the 'end of stream' flag set, but + implementations need to be prepared to deal with truncated streams that do not + have a page marked 'end of stream'. +There is no reason for the final packet on the last page to be a continued + packet, i.e., for the final lacing value to be 255. +However, demuxers might encounter such streams, possibly as the result of a + transfer that did not complete or of corruption. +If a packet continues onto a subsequent page (i.e., when the page ends with a + lacing value of 255) and one of the following conditions is also true: + +the next page with packet data does not have the 'continued packet' flag + set OR +there is no next page with packet data OR +the page sequence numbers are not consecutive, + + then a demuxer MUST NOT attempt to decode the data from that packet unless the + demuxer has some special knowledge that would allow it to interpret this data + despite the missing pieces. +There MUST NOT be any more pages in an Opus logical bitstream after a page + marked 'end of stream'. + +

    + +The granule position MUST be zero for the ID header page and the + page where the comment header completes. +That is, the first page in the logical stream, and the last header + page before the first audio data page both have a granule position of zero. + + +The granule position of an audio data page encodes the total number of PCM + samples in the stream up to and including the last fully-decodable sample from + the last packet completed on that page. +The granule position of the first audio data page will usually be larger than + zero, as described in . + + + +A page that is entirely spanned by a single packet (that completes on a + subsequent page) has no granule position, and the granule position field is + set to the special value '-1' in two's complement. + + + +The granule position of an audio data page is in units of PCM audio samples at + a fixed rate of 48 kHz (per channel; a stereo stream's granule position + does not increment at twice the speed of a mono stream). +It is possible to run an Opus decoder at other sampling rates, + but all Opus packets encode samples at a sampling rate that evenly divides + 48 kHz. +Therefore, the value in the granule position field always counts samples + assuming a 48 kHz decoding rate, and the rest of this specification makes + the same assumption. + + + +The duration of an Opus packet as defined in can be + any multiple of 2.5 ms, up to a maximum of 120 ms. +This duration is encoded in the TOC sequence at the beginning of each packet. +The number of samples returned by a decoder corresponds to this duration + exactly, even for the first few packets. +For example, a 20 ms packet fed to a decoder running at 48 kHz will + always return 960 samples. +A demuxer can parse the TOC sequence at the beginning of each Ogg packet to + work backwards or forwards from a packet with a known granule position (i.e., + the last packet completed on some page) in order to assign granule positions + to every packet, or even every individual sample. +The one exception is the last page in the stream, as described below. + + + +All other pages with completed packets after the first MUST have a granule + position equal to the number of samples contained in packets that complete on + that page plus the granule position of the most recent page with completed + packets. +This guarantees that a demuxer can assign individual packets the same granule + position when working forwards as when working backwards. +For this to work, there cannot be any gaps. + + +
    + +In order to support capturing a real-time stream that has lost or not + transmitted packets, a multiplexer (muxer) SHOULD emit packets that explicitly + request the use of Packet Loss Concealment (PLC) in place of the missing + packets. +Implementations that fail to do so still MUST NOT increment the granule + position for a page by anything other than the number of samples contained in + packets that actually complete on that page. + + +Only gaps that are a multiple of 2.5 ms are repairable, as these are the + only durations that can be created by packet loss or discontinuous + transmission. +Muxers need not handle other gap sizes. +Creating the necessary packets involves synthesizing a TOC byte (defined in +Section 3.1 of )—and whatever + additional internal framing is needed—to indicate the packet duration + for each stream. +The actual length of each missing Opus frame inside the packet is zero bytes, + as defined in Section 3.2.1 of . + + + +Zero-byte frames MAY be packed into packets using any of codes 0, 1, + 2, or 3. +When successive frames have the same configuration, the higher code packings + reduce overhead. +Likewise, if the TOC configuration matches, the muxer MAY further combine the + empty frames with previous or subsequent non-zero-length frames (using + code 2 or VBR code 3). + + + + does not impose any requirements on the PLC, but this + section outlines choices that are expected to have a positive influence on + most PLC implementations, including the reference implementation. +Synthesized TOC sequences SHOULD maintain the same mode, audio bandwidth, + channel count, and frame size as the previous packet (if any). +This is the simplest and usually the most well-tested case for the PLC to + handle and it covers all losses that do not include a configuration switch, + as defined in Section 4.5 of . + + + +When a previous packet is available, keeping the audio bandwidth and channel + count the same allows the PLC to provide maximum continuity in the concealment + data it generates. +However, if the size of the gap is not a multiple of the most recent frame + size, then the frame size will have to change for at least some frames. +Such changes SHOULD be delayed as long as possible to simplify + things for PLC implementations. + + + +As an example, a 95 ms gap could be encoded as nineteen 5 ms frames + in two bytes with a single CBR code 3 packet. +If the previous frame size was 20 ms, using four 20 ms frames + followed by three 5 ms frames requires 4 bytes (plus an extra byte + of Ogg lacing overhead), but allows the PLC to use its well-tested steady + state behavior for as long as possible. +The total bitrate of the latter approach, including Ogg overhead, is about + 0.4 kbps, so the impact on file size is minimal. + + + +Changing modes is discouraged, since this causes some decoder implementations + to reset their PLC state. +However, SILK and Hybrid mode frames cannot fill gaps that are not a multiple + of 10 ms. +If switching to CELT mode is needed to match the gap size, a muxer SHOULD do + so at the end of the gap to allow the PLC to function for as long as possible. + + + +In the example above, if the previous frame was a 20 ms SILK mode frame, + the better solution is to synthesize a packet describing four 20 ms SILK + frames, followed by a packet with a single 10 ms SILK + frame, and finally a packet with a 5 ms CELT frame, to fill the 95 ms + gap. +This also requires four bytes to describe the synthesized packet data (two + bytes for a CBR code 3 and one byte each for two code 0 packets) but three + bytes of Ogg lacing overhead are needed to mark the packet boundaries. +At 0.6 kbps, this is still a minimal bitrate impact over a naive, low quality + solution. + + + +Since medium-band audio is an option only in the SILK mode, wideband frames + SHOULD be generated if switching from that configuration to CELT mode, to + ensure that any PLC implementation which does try to migrate state between + the modes will be able to preserve all of the available audio bandwidth. + + +
    + +
    + +There is some amount of latency introduced during the decoding process, to + allow for overlap in the CELT mode, stereo mixing in the SILK mode, and + resampling. +The encoder might have introduced additional latency through its own resampling + and analysis (though the exact amount is not specified). +Therefore, the first few samples produced by the decoder do not correspond to + real input audio, but are instead composed of padding inserted by the encoder + to compensate for this latency. +These samples need to be stored and decoded, as Opus is an asymptotically + convergent predictive codec, meaning the decoded contents of each frame depend + on the recent history of decoder inputs. +However, a player will want to skip these samples after decoding them. + + + +A 'pre-skip' field in the ID header (see ) signals + the number of samples that SHOULD be skipped (decoded but discarded) at the + beginning of the stream, though some specific applications might have a reason + for looking at that data. +This amount need not be a multiple of 2.5 ms, MAY be smaller than a single + packet, or MAY span the contents of several packets. +These samples are not valid audio. + + + +For example, if the first Opus frame uses the CELT mode, it will always + produce 120 samples of windowed overlap-add data. +However, the overlap data is initially all zeros (since there is no prior + frame), meaning this cannot, in general, accurately represent the original + audio. +The SILK mode requires additional delay to account for its analysis and + resampling latency. +The encoder delays the original audio to avoid this problem. + + + +The pre-skip field MAY also be used to perform sample-accurate cropping of + already encoded streams. +In this case, a value of at least 3840 samples (80 ms) provides + sufficient history to the decoder that it will have converged + before the stream's output begins. + + +
    + +
    + +The PCM sample position is determined from the granule position using the + formula + +
    + +
    + + +For example, if the granule position of the first audio data page is 59,971, + and the pre-skip is 11,971, then the PCM sample position of the last decoded + sample from that page is 48,000. + + +This can be converted into a playback time using the formula + +
    + +
    + + +The initial PCM sample position before any samples are played is normally '0'. +In this case, the PCM sample position of the first audio sample to be played + starts at '1', because it marks the time on the clock + after that sample has been played, and a stream + that is exactly one second long has a final PCM sample position of '48000', + as in the example here. + + + +Vorbis streams use a granule position smaller than the number of audio samples + contained in the first audio data page to indicate that some of those samples + are trimmed from the output (see ). +However, to do so, Vorbis requires that the first audio data page contains + exactly two packets, in order to allow the decoder to perform PCM position + adjustments before needing to return any PCM data. +Opus uses the pre-skip mechanism for this purpose instead, since the encoder + might introduce more than a single packet's worth of latency, and since very + large packets in streams with a very large number of channels might not fit + on a single page. + +
    + +
    + +The page with the 'end of stream' flag set MAY have a granule position that + indicates the page contains less audio data than would normally be returned by + decoding up through the final packet. +This is used to end the stream somewhere other than an even frame boundary. +The granule position of the most recent audio data page with completed packets + is used to make this determination, or '0' is used if there were no previous + audio data pages with a completed packet. +The difference between these granule positions indicates how many samples to + keep after decoding the packets that completed on the final page. +The remaining samples are discarded. +The number of discarded samples SHOULD be no larger than the number decoded + from the last packet. + +
    + +
    + +The granule position of the first audio data page with a completed packet MAY + be larger than the number of samples contained in packets that complete on + that page, however it MUST NOT be smaller, unless that page has the 'end of + stream' flag set. +Allowing a granule position larger than the number of samples allows the + beginning of a stream to be cropped or a live stream to be joined without + rewriting the granule position of all the remaining pages. +This means that the PCM sample position just before the first sample to be + played MAY be larger than '0'. +Synchronization when multiplexing with other logical streams still uses the PCM + sample position relative to '0' to compute sample times. +This does not affect the behavior of pre-skip: exactly 'pre-skip' samples + SHOULD be skipped from the beginning of the decoded output, even if the + initial PCM sample position is greater than zero. + + + +On the other hand, a granule position that is smaller than the number of + decoded samples prevents a demuxer from working backwards to assign each + packet or each individual sample a valid granule position, since granule + positions are non-negative. +An implementation MUST treat any stream as invalid if the granule position + is smaller than the number of samples contained in packets that complete on + the first audio data page with a completed packet, unless that page has the + 'end of stream' flag set. +It MAY defer this action until it decodes the last packet completed on that + page. + + + +If that page has the 'end of stream' flag set, a demuxer MUST treat any stream + as invalid if its granule position is smaller than the 'pre-skip' amount. +This would indicate that there are more samples to be skipped from the initial + decoded output than exist in the stream. +If the granule position is smaller than the number of decoded samples produced + by the packets that complete on that page, then a demuxer MUST use an initial + granule position of '0', and can work forwards from '0' to timestamp + individual packets. +If the granule position is larger than the number of decoded samples available, + then the demuxer MUST still work backwards as described above, even if the + 'end of stream' flag is set, to determine the initial granule position, and + thus the initial PCM sample position. +Both of these will be greater than '0' in this case. + +
    + +
    + +Seeking in Ogg files is best performed using a bisection search for a page + whose granule position corresponds to a PCM position at or before the seek + target. +With appropriately weighted bisection, accurate seeking can be performed in + just one or two bisections on average, even in multi-gigabyte files. +See for an example of general implementation guidance. + + + +When seeking within an Ogg Opus stream, an implementation SHOULD start decoding + (and discarding the output) at least 3840 samples (80 ms) prior to + the seek target in order to ensure that the output audio is correct by the + time it reaches the seek target. +This 'pre-roll' is separate from, and unrelated to, the 'pre-skip' used at the + beginning of the stream. +If the point 80 ms prior to the seek target comes before the initial PCM + sample position, an implementation SHOULD start decoding from the beginning of + the stream, applying pre-skip as normal, regardless of whether the pre-skip is + larger or smaller than 80 ms, and then continue to discard samples + to reach the seek target (if any). + +
    + +
    + +
    + +An Ogg Opus logical stream contains exactly two mandatory header packets: + an identification header and a comment header. + + +
    + +
    + +
    + + +The fields in the identification (ID) header have the following meaning: + +Magic Signature: + +This is an 8-octet (64-bit) field that allows codec identification and is + human-readable. +It contains, in order, the magic numbers: + +0x4F 'O' +0x70 'p' +0x75 'u' +0x73 's' +0x48 'H' +0x65 'e' +0x61 'a' +0x64 'd' + +Starting with "Op" helps distinguish it from audio data packets, as this is an + invalid TOC sequence. + + +Version (8 bits, unsigned): + +The version number MUST always be '1' for this version of the encapsulation + specification. +Implementations SHOULD treat streams where the upper four bits of the version + number match that of a recognized specification as backwards-compatible with + that specification. +That is, the version number can be split into "major" and "minor" version + sub-fields, with changes to the "minor" sub-field (in the lower four bits) + signaling compatible changes. +For example, an implementation of this specification SHOULD accept any stream + with a version number of '15' or less, and SHOULD assume any stream with a + version number '16' or greater is incompatible. +The initial version '1' was chosen to keep implementations from relying on this + octet as a null terminator for the "OpusHead" string. + + +Output Channel Count 'C' (8 bits, unsigned): + +This is the number of output channels. +This might be different than the number of encoded channels, which can change + on a packet-by-packet basis. +This value MUST NOT be zero. +The maximum allowable value depends on the channel mapping family, and might be + as large as 255. +See for details. + + +Pre-skip (16 bits, unsigned, little + endian): + +This is the number of samples (at 48 kHz) to discard from the decoder + output when starting playback, and also the number to subtract from a page's + granule position to calculate its PCM sample position. +When cropping the beginning of existing Ogg Opus streams, a pre-skip of at + least 3,840 samples (80 ms) is RECOMMENDED to ensure complete + convergence in the decoder. + + +Input Sample Rate (32 bits, unsigned, little + endian): + +This is the sample rate of the original input (before encoding), in Hz. +This field is not the sample rate to use for + playback of the encoded data. + +Opus can switch between internal audio bandwidths of 4, 6, 8, 12, and + 20 kHz. +Each packet in the stream can have a different audio bandwidth. +Regardless of the audio bandwidth, the reference decoder supports decoding any + stream at a sample rate of 8, 12, 16, 24, or 48 kHz. +The original sample rate of the audio passed to the encoder is not preserved + by the lossy compression. + +An Ogg Opus player SHOULD select the playback sample rate according to the + following procedure: + +If the hardware supports 48 kHz playback, decode at 48 kHz. +Otherwise, if the hardware's highest available sample rate is a supported + rate, decode at this sample rate. +Otherwise, if the hardware's highest available sample rate is less than + 48 kHz, decode at the next higher Opus supported rate above the highest + available hardware rate and resample. +Otherwise, decode at 48 kHz and resample. + +However, the 'Input Sample Rate' field allows the muxer to pass the sample + rate of the original input stream as metadata. +This is useful when the user requires the output sample rate to match the + input sample rate. +For example, when not playing the output, an implementation writing PCM format + samples to disk might choose to resample the audio back to the original input + sample rate to reduce surprise to the user, who might reasonably expect to get + back a file with the same sample rate. + +A value of zero indicates 'unspecified'. +Muxers SHOULD write the actual input sample rate or zero, but implementations + which do something with this field SHOULD take care to behave sanely if given + crazy values (e.g., do not actually upsample the output to 10 MHz if + requested). +Implementations SHOULD support input sample rates between 8 kHz and + 192 kHz (inclusive). +Rates outside this range MAY be ignored by falling back to the default rate of + 48 kHz instead. + + +Output Gain (16 bits, signed, little endian): + +This is a gain to be applied when decoding. +It is 20*log10 of the factor by which to scale the decoder output to achieve + the desired playback volume, stored in a 16-bit, signed, two's complement + fixed-point value with 8 fractional bits (i.e., + Q7.8 ). + +To apply the gain, an implementation could use +
    + +
    + where output_gain is the raw 16-bit value from the header. + +Players and media frameworks SHOULD apply it by default. +If a player chooses to apply any volume adjustment or gain modification, such + as the R128_TRACK_GAIN (see ), the adjustment + MUST be applied in addition to this output gain in order to achieve playback + at the normalized volume. + +A muxer SHOULD set this field to zero, and instead apply any gain prior to + encoding, when this is possible and does not conflict with the user's wishes. +A nonzero output gain indicates the gain was adjusted after encoding, or that + a user wished to adjust the gain for playback while preserving the ability + to recover the original signal amplitude. + +Although the output gain has enormous range (+/- 128 dB, enough to amplify + inaudible sounds to the threshold of physical pain), most applications can + only reasonably use a small portion of this range around zero. +The large range serves in part to ensure that gain can always be losslessly + transferred between OpusHead and R128 gain tags (see below) without + saturating. + +     +Channel Mapping Family (8 bits, unsigned): + +This octet indicates the order and semantic meaning of the output channels. + +Each currently specified value of this octet indicates a mapping family, which + defines a set of allowed channel counts, and the ordered set of channel names + for each allowed channel count. +The details are described in . + +Channel Mapping Table: +This table defines the mapping from encoded streams to output channels. +Its contents are specified in . + +     +     + + +All fields in the ID headers are REQUIRED, except for the channel mapping + table, which MUST be omitted when the channel mapping family is 0, but + is REQUIRED otherwise. +Implementations SHOULD treat a stream as invalid if it contains an ID header + that does not have enough data for these fields, even if it contain a valid + Magic Signature. +Future versions of this specification, even backwards-compatible versions, + might include additional fields in the ID header. +If an ID header has a compatible major version, but a larger minor version, + an implementation MUST NOT treat it as invalid for containing additional data + not specified here, provided it still completes on the first page. + + +
    + +An Ogg Opus stream allows mapping one number of Opus streams (N) to a possibly + larger number of decoded channels (M + N) to yet another number of + output channels (C), which might be larger or smaller than the number of + decoded channels. +The order and meaning of these channels are defined by a channel mapping, + which consists of the 'channel mapping family' octet and, for channel mapping + families other than family 0, a channel mapping table, as illustrated in + . + + +
    + +
    + + +The fields in the channel mapping table have the following meaning: + +Stream Count 'N' (8 bits, unsigned): + +This is the total number of streams encoded in each Ogg packet. +This value is necessary to correctly parse the packed Opus packets inside an + Ogg packet, as described in . +This value MUST NOT be zero, as without at least one Opus packet with a valid + TOC sequence, a demuxer cannot recover the duration of an Ogg packet. + +For channel mapping family 0, this value defaults to 1, and is not coded. + + +Coupled Stream Count 'M' (8 bits, unsigned): +This is the number of streams whose decoders are to be configured to produce + two channels (stereo). +This MUST be no larger than the total number of streams, N. + +Each packet in an Opus stream has an internal channel count of 1 or 2, which + can change from packet to packet. +This is selected by the encoder depending on the bitrate and the audio being + encoded. +The original channel count of the audio passed to the encoder is not + necessarily preserved by the lossy compression. + +Regardless of the internal channel count, any Opus stream can be decoded as + mono (a single channel) or stereo (two channels) by appropriate initialization + of the decoder. +The 'coupled stream count' field indicates that the decoders for the first M + Opus streams are to be initialized for stereo (two-channel) output, and the + remaining (N - M) decoders are to be initialized for mono (a single + channel) only. +The total number of decoded channels, (M + N), MUST be no larger than + 255, as there is no way to index more channels than that in the channel + mapping. + +For channel mapping family 0, this value defaults to (C - 1) + (i.e., 0 for mono and 1 for stereo), and is not coded. + + +Channel Mapping (8*C bits): +This contains one octet per output channel, indicating which decoded channel + is to be used for each one. +Let 'index' be the value of this octet for a particular output channel. +This value MUST either be smaller than (M + N), or be the special + value 255. +If 'index' is less than 2*M, the output MUST be taken from decoding stream + ('index'/2) as stereo and selecting the left channel if 'index' is even, and + the right channel if 'index' is odd. +If 'index' is 2*M or larger, but less than 255, the output MUST be taken from + decoding stream ('index' - M) as mono. +If 'index' is 255, the corresponding output channel MUST contain pure silence. + +The number of output channels, C, is not constrained to match the number of + decoded channels (M + N). +A single index value MAY appear multiple times, i.e., the same decoded channel + might be mapped to multiple output channels. +Some decoded channels might not be assigned to any output channel, as well. + +For channel mapping family 0, the first index defaults to 0, and if + C == 2, the second index defaults to 1. +Neither index is coded. + + + + + +After producing the output channels, the channel mapping family determines the + semantic meaning of each one. +There are three defined mapping families in this specification. + + +
    + +Allowed numbers of channels: 1 or 2. +RTP mapping. +This is the same channel interpretation as . + + + +1 channel: monophonic (mono). +2 channels: stereo (left, right). + +Special mapping: This channel mapping value also + indicates that the contents consists of a single Opus stream that is stereo if + and only if C == 2, with stream index 0 mapped to output + channel 0 (mono, or left channel) and stream index 1 mapped to + output channel 1 (right channel) if stereo. +When the 'channel mapping family' octet has this value, the channel mapping + table MUST be omitted from the ID header packet. + +
    + +
    + +Allowed numbers of channels: 1...8. +Vorbis channel order (see below). + + +Each channel is assigned to a speaker location in a conventional surround + arrangement. +Specific locations depend on the number of channels, and are given below + in order of the corresponding channel indices. + + 1 channel: monophonic (mono). + 2 channels: stereo (left, right). + 3 channels: linear surround (left, center, right) + 4 channels: quadraphonic (front left, front right, rear left, rear right). + 5 channels: 5.0 surround (front left, front center, front right, rear left, rear right). + 6 channels: 5.1 surround (front left, front center, front right, rear left, rear right, LFE). + 7 channels: 6.1 surround (front left, front center, front right, side left, side right, rear center, LFE). + 8 channels: 7.1 surround (front left, front center, front right, side left, side right, rear left, rear right, LFE) + + + +This set of surround options and speaker location orderings is the same + as those used by the Vorbis codec . +The ordering is different from the one used by the + WAVE and + Free Lossless Audio Codec (FLAC) formats, + so correct ordering requires permutation of the output channels when decoding + to or encoding from those formats. +'LFE' here refers to a Low Frequency Effects channel, often mapped to a + subwoofer with no particular spatial position. +Implementations SHOULD identify 'side' or 'rear' speaker locations with + 'surround' and 'back' as appropriate when interfacing with audio formats + or systems which prefer that terminology. + +
    + +
    + +Allowed numbers of channels: 1...255. +No defined channel meaning. + + +Channels are unidentified. +General-purpose players SHOULD NOT attempt to play these streams. +Offline implementations MAY deinterleave the output into separate PCM files, + one per channel. +Implementations SHOULD NOT produce output for channels mapped to stream index + 255 (pure silence) unless they have no other way to indicate the index of + non-silent channels. + +
    + +
    + +The remaining channel mapping families (2...254) are reserved. +A demuxer implementation encountering a reserved channel mapping family value + SHOULD act as though the value is 255. + +
    + +
    + +An Ogg Opus player MUST support any valid channel mapping with a channel + mapping family of 0 or 1, even if the number of channels does not match the + physically connected audio hardware. +Players SHOULD perform channel mixing to increase or reduce the number of + channels as needed. + + + +Implementations MAY use the matrices in + Figures  + through  to implement + downmixing from multichannel files using + Channel Mapping Family 1, which are + known to give acceptable results for stereo. +Matrices for 3 and 4 channels are normalized so each coefficient row sums + to 1 to avoid clipping. +For 5 or more channels they are normalized to 2 as a compromise between + clipping and dynamic range reduction. + + +In these matrices the front left and front right channels are generally +passed through directly. +When a surround channel is split between both the left and right stereo + channels, coefficients are chosen so their squares sum to 1, which + helps preserve the perceived intensity. +Rear channels are mixed more diffusely or attenuated to maintain focus + on the front channels. + + +
    + + +Exact coefficient values are 1 and 1/sqrt(2), multiplied by + 1/(1 + 1/sqrt(2)) for normalization. + +

    + + +The comment header consists of a 64-bit magic signature, followed by data in + the same format as the header used in Ogg + Vorbis, except (like Ogg Theora and Speex) the final "framing bit" specified + in the Vorbis spec is not present. + +Magic Signature: + +This is an 8-octet (64-bit) field that allows codec identification and is + human-readable. +It contains, in order, the magic numbers: + +0x4F 'O' +0x70 'p' +0x75 'u' +0x73 's' +0x54 'T' +0x61 'a' +0x67 'g' +0x73 's' + +Starting with "Op" helps distinguish it from audio data packets, as this is an + invalid TOC sequence. + + +Vendor String Length (32 bits, unsigned, little endian): + +This field gives the length of the following vendor string, in octets. +It MUST NOT indicate that the vendor string is longer than the rest of the + packet. + + +Vendor String (variable length, UTF-8 vector): + +This is a simple human-readable tag for vendor information, encoded as a UTF-8 + string . +No terminating null octet is necessary. + +This tag is intended to identify the codec encoder and encapsulation + implementations, for tracing differences in technical behavior. +User-facing applications can use the 'ENCODER' user comment tag to identify + themselves. + + +User Comment List Length (32 bits, unsigned, little endian): + +This field indicates the number of user-supplied comments. +It MAY indicate there are zero user-supplied comments, in which case there are + no additional fields in the packet. +It MUST NOT indicate that there are so many comments that the comment string + lengths would require more data than is available in the rest of the packet. + + +User Comment #i String Length (32 bits, unsigned, little endian): + +This field gives the length of the following user comment string, in octets. +There is one for each user comment indicated by the 'user comment list length' + field. +It MUST NOT indicate that the string is longer than the rest of the packet. + + +User Comment #i String (variable length, UTF-8 vector): + +This field contains a single user comment encoded as a UTF-8 + string . +There is one for each user comment indicated by the 'user comment list length' + field. + + + + + +The vendor string length and user comment list length are REQUIRED, and + implementations SHOULD treat a stream as invalid if it contains a comment + header that does not have enough data for these fields, or that does not + contain enough data for the corresponding vendor string or user comments they + describe. +Making this check before allocating the associated memory to contain the data + helps prevent a possible Denial-of-Service (DoS) attack from small comment + headers that claim to contain strings longer than the entire packet or more + user comments than than could possibly fit in the packet. + + + +Immediately following the user comment list, the comment header MAY + contain zero-padding or other binary data which is not specified here. +If the least-significant bit of the first byte of this data is 1, then editors + SHOULD preserve the contents of this data when updating the tags, but if this + bit is 0, all such data MAY be treated as padding, and truncated or discarded + as desired. +This allows informal experimentation with the format of this binary data until + it can be specified later. + + + +The comment header can be arbitrarily large and might be spread over a large + number of Ogg pages. +Implementations MUST avoid attempting to allocate excessive amounts of memory + when presented with a very large comment header. +To accomplish this, implementations MAY treat a stream as invalid if it has a + comment header larger than 125,829,120 octets (120 MB), and MAY + ignore individual comments that are not fully contained within the first + 61,440 octets of the comment header. + + +
    + +The user comment strings follow the NAME=value format described by + with the same recommended tag names: + ARTIST, TITLE, DATE, ALBUM, and so on. + + +Two new comment tags are introduced here: + + +First, an optional gain for track normalization: +
    + +
    + + representing the volume shift needed to normalize the track's volume + during isolated playback, in random shuffle, and so on. +The gain is a Q7.8 fixed point number in dB, as in the ID header's 'output + gain' field. +This tag is similar to the REPLAYGAIN_TRACK_GAIN tag in + Vorbis , except that the normal volume + reference is the standard. + +Second, an optional gain for album normalization: +
    + +
    + + representing the volume shift needed to normalize the overall volume when + played as part of a particular collection of tracks. +The gain is also a Q7.8 fixed point number in dB, as in the ID header's + 'output gain' field. +The values '-573' and '111' given here are just examples. + + +An Ogg Opus stream MUST NOT have more than one of each of these tags, and if + present their values MUST be an integer from -32768 to 32767, inclusive, + represented in ASCII as a base 10 number with no whitespace. +A leading '+' or '-' character is valid. +Leading zeros are also permitted, but the value MUST be represented by + no more than 6 characters. +Other non-digit characters MUST NOT be present. + + +If present, R128_TRACK_GAIN and R128_ALBUM_GAIN MUST correctly represent + the R128 normalization gain relative to the 'output gain' field specified + in the ID header. +If a player chooses to make use of the R128_TRACK_GAIN tag or the + R128_ALBUM_GAIN tag, it MUST apply those gains + in addition to the 'output gain' value. +If a tool modifies the ID header's 'output gain' field, it MUST also update or + remove the R128_TRACK_GAIN and R128_ALBUM_GAIN comment tags if present. +A muxer SHOULD place the gain it wants other tools to use by default into the + 'output gain' field, and not the comment tag. + + +To avoid confusion with multiple normalization schemes, an Opus comment header + SHOULD NOT contain any of the REPLAYGAIN_TRACK_GAIN, REPLAYGAIN_TRACK_PEAK, + REPLAYGAIN_ALBUM_GAIN, or REPLAYGAIN_ALBUM_PEAK tags, unless they are only + to be used in some context where there is guaranteed to be no such confusion. + normalization is preferred to the earlier + REPLAYGAIN schemes because of its clear definition and adoption by industry. +Peak normalizations are difficult to calculate reliably for lossy codecs + because of variation in excursion heights due to decoder differences. +In the authors' investigations they were not applied consistently or broadly + enough to merit inclusion here. + +
    +
    + +
    + +
    + +Technically, valid Opus packets can be arbitrarily large due to the padding + format, although the amount of non-padding data they can contain is bounded. +These packets might be spread over a similarly enormous number of Ogg pages. +When encoding, implementations SHOULD limit the use of padding in audio data + packets to no more than is necessary to make a variable bitrate (VBR) stream + constant bitrate (CBR), unless they have no reasonable way to determine what + is necessary. +Demuxers SHOULD treat audio data packets as invalid (treat them as if they were + malformed Opus packets with an invalid TOC sequence) if they are larger than + 61,440 octets per Opus stream, unless they have a specific reason for + allowing extra padding. +Such packets necessarily contain more padding than needed to make a stream CBR. +Demuxers MUST avoid attempting to allocate excessive amounts of memory when + presented with a very large packet. +Demuxers MAY treat audio data packets as invalid or partially process them if + they are larger than 61,440 octets in an Ogg Opus stream with channel + mapping families 0 or 1. +Demuxers MAY treat audio data packets as invalid or partially process them in + any Ogg Opus stream if the packet is larger than 61,440 octets and also + larger than 7,680 octets per Opus stream. +The presence of an extremely large packet in the stream could indicate a + memory exhaustion attack or stream corruption. + + +In an Ogg Opus stream, the largest possible valid packet that does not use + padding has a size of (61,298*N - 2) octets. +With 255 streams, this is 15,630,988 octets and can + span up to 61,298 Ogg pages, all but one of which will have a granule + position of -1. +This is of course a very extreme packet, consisting of 255 streams, each + containing 120 ms of audio encoded as 2.5 ms frames, each frame + using the maximum possible number of octets (1275) and stored in the least + efficient manner allowed (a VBR code 3 Opus packet). +Even in such a packet, most of the data will be zeros as 2.5 ms frames + cannot actually use all 1275 octets. + + +The largest packet consisting of entirely useful data is + (15,326*N - 2) octets. +This corresponds to 120 ms of audio encoded as 10 ms frames in either + SILK or Hybrid mode, but at a data rate of over 1 Mbps, which makes little + sense for the quality achieved. + + +A more reasonable limit is (7,664*N - 2) octets. +This corresponds to 120 ms of audio encoded as 20 ms stereo CELT mode + frames, with a total bitrate just under 511 kbps (not counting the Ogg + encapsulation overhead). +For channel mapping family 1, N=8 provides a reasonable upper bound, as it + allows for each of the 8 possible output channels to be decoded from a + separate stereo Opus stream. +This gives a size of 61,310 octets, which is rounded up to a multiple of + 1,024 octets to yield the audio data packet size of 61,440 octets + that any implementation is expected to be able to process successfully. + +
    + +
    + +When encoding Opus streams, Ogg muxers SHOULD take into account the + algorithmic delay of the Opus encoder. + + +In encoders derived from the reference + implementation , the number of samples can be + queried with: + +
    + +
    + +To achieve good quality in the very first samples of a stream, implementations + MAY use linear predictive coding (LPC) extrapolation to generate at least 120 + extra samples at the beginning to avoid the Opus encoder having to encode a + discontinuous signal. +For more information on linear prediction, see + . +For an input file containing 'length' samples, the implementation SHOULD set + the pre-skip header value to (delay_samples + extra_samples), encode + at least (length + delay_samples + extra_samples) + samples, and set the granule position of the last page to + (length + delay_samples + extra_samples). +This ensures that the encoded file has the same duration as the original, with + no time offset. The best way to pad the end of the stream is to also use LPC + extrapolation, but zero-padding is also acceptable. + + +
    + +The first step in LPC extrapolation is to compute linear prediction + coefficients. +When extending the end of the signal, order-N (typically with N ranging from 8 + to 40) LPC analysis is performed on a window near the end of the signal. +The last N samples are used as memory to an infinite impulse response (IIR) + filter. + + +The filter is then applied on a zero input to extrapolate the end of the signal. +Let a(k) be the kth LPC coefficient and x(n) be the nth sample of the signal, + each new sample past the end of the signal is computed as: + +
    + +
    + +The process is repeated independently for each channel. +It is possible to extend the beginning of the signal by applying the same + process backward in time. +When extending the beginning of the signal, it is best to apply a "fade in" to + the extrapolated signal, e.g. by multiplying it by a half-Hanning window + . + + +
    + +
    + +In some applications, such as Internet radio, it is desirable to cut a long + stream into smaller chains, e.g. so the comment header can be updated. +This can be done simply by separating the input streams into segments and + encoding each segment independently. +The drawback of this approach is that it creates a small discontinuity + at the boundary due to the lossy nature of Opus. +A muxer MAY avoid this discontinuity by using the following procedure: + +Encode the last frame of the first segment as an independent frame by + turning off all forms of inter-frame prediction. +De-emphasis is allowed. +Set the granule position of the last page to a point near the end of the + last frame. +Begin the second segment with a copy of the last frame of the first + segment. +Set the pre-skip value of the second stream in such a way as to properly + join the two streams. +Continue the encoding process normally from there, without any reset to + the encoder. + + + +In encoders derived from the reference implementation, inter-frame prediction + can be turned off by calling: + +
    + +
    + +For best results, this implementation requires that prediction be explicitly + enabled again before resuming normal encoding, even after a reset. + + +

    + +
    + +Implementations of the Opus codec need to take appropriate security + considerations into account, as outlined in . +This is just as much a problem for the container as it is for the codec itself. +Malicious payloads and/or input streams can be used to attack codec + implementations. +Implementations MUST NOT overrun their allocated memory nor consume excessive + resources when decoding payloads or processing input streams. +Although problems in encoding applications are typically rarer, this still + applies to a muxer, as vulnerabilities would allow an attacker to attack + transcoding gateways. + + + +Header parsing code contains the most likely area for potential overruns. +It is important for implementations to ensure their buffers contain enough + data for all of the required fields before attempting to read it (for example, + for all of the channel map data in the ID header). +Implementations would do well to validate the indices of the channel map, also, + to ensure they meet all of the restrictions outlined in + , in order to avoid attempting to read data + from channels that do not exist. + + + +To avoid excessive resource usage, we advise implementations to be especially + wary of streams that might cause them to process far more data than was + actually transmitted. +For example, a relatively small comment header may contain values for the + string lengths or user comment list length that imply that it is many + gigabytes in size. +Even computing the size of the required buffer could overflow a 32-bit integer, + and actually attempting to allocate such a buffer before verifying it would be + a reasonable size is a bad idea. +After reading the user comment list length, implementations might wish to + verify that the header contains at least the minimum amount of data for that + many comments (4 additional octets per comment, to indicate each has a + length of zero) before proceeding any further, again taking care to avoid + overflow in these calculations. +If allocating an array of pointers to point at these strings, the size of the + pointers may be larger than 4 octets, potentially requiring a separate + overflow check. + + + +Another bug in this class we have observed more than once involves the handling + of invalid data at the end of a stream. +Often, implementations will seek to the end of a stream to locate the last + timestamp in order to compute its total duration. +If they do not find a valid capture pattern and Ogg page from the desired + logical stream, they will back up and try again. +If care is not taken to avoid re-scanning data that was already scanned, this + search can quickly devolve into something with a complexity that is quadratic + in the amount of invalid data. + + + +In general when seeking, implementations will wish to be cautious about the + effects of invalid granule position values, and ensure all algorithms will + continue to make progress and eventually terminate, even if these are missing + or out-of-order. + + + +Like most other container formats, Ogg Opus streams SHOULD NOT be used with + insecure ciphers or cipher modes that are vulnerable to known-plaintext + attacks. +Elements such as the Ogg page capture pattern and the magic signatures in the + ID header and the comment header all have easily predictable values, in + addition to various elements of the codec data itself. + +
    + +
    + +An "Ogg Opus file" consists of one or more sequentially multiplexed segments, + each containing exactly one Ogg Opus stream. +The RECOMMENDED mime-type for Ogg Opus files is "audio/ogg". + + + +If more specificity is desired, one MAY indicate the presence of Opus streams + using the codecs parameter defined in and + , e.g., + +
    + +
    + + for an Ogg Opus file. + + + +The RECOMMENDED filename extension for Ogg Opus files is '.opus'. + + + +When Opus is concurrently multiplexed with other streams in an Ogg container, + one SHOULD use one of the "audio/ogg", "video/ogg", or "application/ogg" + mime-types, as defined in . +Such streams are not strictly "Ogg Opus files" as described above, + since they contain more than a single Opus stream per sequentially + multiplexed segment, e.g. video or multiple audio tracks. +In such cases the the '.opus' filename extension is NOT RECOMMENDED. + + + +In either case, this document updates + to add 'opus' as a codecs parameter value with char[8]: 'OpusHead' + as Codec Identifier. + +
    + +
    + +This document updates the IANA Media Types registry to add .opus + as a file extension for "audio/ogg", and to add itself as a reference + alongside for "audio/ogg", "video/ogg", and + "application/ogg" Media Types. + + +This document defines a new registry "Opus Channel Mapping Families" to + indicate how the semantic meanings of the channels in a multi-channel Opus + stream are described. +IANA is requested to create a new name space of "Opus Channel Mapping + Families". +This will be a new registry on the IANA Matrix, and not a subregistry of an + existing registry. +Modifications to this registry follow the "Specification Required" registration + policy as defined in . +Each registry entry consists of a Channel Mapping Family Number, which is + specified in decimal in the range 0 to 255, inclusive, and a Reference (or + list of references) +Each Reference must point to sufficient documentation to describe what + information is coded in the Opus identification header for this channel + mapping family, how a demuxer determines the Stream Count ('N') and Coupled + Stream Count ('M') from this information, and how it determines the proper + interpretation of each of the decoded channels. + + +This document defines three initial assignments for this registry. + + +ValueReference +0[RFCXXXX] +1[RFCXXXX] +255[RFCXXXX] + + +The designated expert will determine if the Reference points to a specification + that meets the requirements for permanence and ready availability laid out + in  and that it specifies the information + described above with sufficient clarity to allow interoperable + implementations. + +

    +     + + + + + + + This document addresses minor issues that were found in the specification + of the Opus audio codec in RFC 6716. It updates the normative decoder implementation + included in the appendix of RFC 6716. The changes fixes real and potential security-related + issues, as well minor quality-related issues. + +     + + +
    + This document addresses minor issues that were discovered in the reference + implementation of the Opus codec. Unlike most IETF specifications, Opus is defined + in RFC 6716 in terms of a normative reference + decoder implementation rather than from the associated text description. + That RFC includes the reference decoder implementation as Appendix A. + That's why only issues affecting the decoder are + listed here. An up-to-date implementation of the Opus encoder can be found at + . + + Some of the changes in this document update normative behaviour in a way that requires + new test vectors. The English text of the specification is unaffected, only + the C implementation is. The updated specification remains fully compatible with + the original specification. + + + + Note: due to RFC formatting conventions, lines exceeding the column width + in the patch are split using a backslash character. The backslashes + at the end of a line and the white space at the beginning + of the following line are not part of the patch. A properly formatted patch + including all changes is available at + + and has a SHA-1 hash of 029e3aa88fc342c91e67a21e7bfbc9458661cd5f. + + +
    + +
    + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in RFC 2119. +
    + +
    + The reference implementation does not reinitialize the stereo state + during a mode switch. The old stereo memory can produce a brief impulse + (i.e. single sample) in the decoded audio. This can be fixed by changing + silk/dec_API.c at line 72: + +
    + + for( n = 0; n < DECODER_NUM_CHANNELS; n++ ) { + ret = silk_init_decoder( &channel_state[ n ] ); + } ++ silk_memset(&((silk_decoder *)decState)->sStereo, 0, ++ sizeof(((silk_decoder *)decState)->sStereo)); ++ /* Not strictly needed, but it's cleaner that way */ ++ ((silk_decoder *)decState)->prev_decode_only_middle = 0; + + return ret; + } + +]]> +
    + + This change affects the normative output of the decoder, but the + amount of change is within the tolerance and too small to make the testvector check fail. + +
    + +
    + It was discovered that some invalid packets of very large size could trigger + an out-of-bounds read in the Opus packet parsing code responsible for padding. + This is due to an integer overflow if the signaled padding exceeds 2^31-1 bytes + (the actual packet may be smaller). The code can be fixed by decrementing the + (signed) len value, instead of incrementing a separate padding counter. + This is done by applying the following changes at line 596 of src/opus_decoder.c: + +
    + + /* Padding flag is bit 6 */ + if (ch&0x40) + { +- int padding=0; + int p; + do { + if (len<=0) + return OPUS_INVALID_PACKET; + p = *data++; + len--; +- padding += p==255 ? 254: p; ++ len -= p==255 ? 254: p; + } while (p==255); +- len -= padding; + } + +]]> +
    + This packet parsing issue is limited to reading memory up + to about 60 kB beyond the compressed buffer. This can only be triggered + by a compressed packet more than about 16 MB long, so it's not a problem + for RTP. In theory, it could crash a file + decoder (e.g. Opus in Ogg) if the memory just after the incoming packet + is out-of-range, but our attempts to trigger such a crash in a production + application built using an affected version of the Opus decoder failed. +
    + +
    + The SILK resampler had the following issues: + + The calls to memcpy() were using sizeof(opus_int32), but the type of the + local buffer was opus_int16. + Because the size was wrong, this potentially allowed the source + and destination regions of the memcpy() to overlap on the copy from "buf" to "buf". + We believe that nSamplesIn (number of input samples) is at least fs_in_khZ (sampling rate in kHz), + which is at least 8. + Since RESAMPLER_ORDER_FIR_12 is only 8, that should not be a problem once + the type size is fixed. + The size of the buffer used RESAMPLER_MAX_BATCH_SIZE_IN, but the + data stored in it was actually twice the input batch size + (nSamplesIn<<1). + + The code can be fixed by applying the following changes to line 78 of silk/resampler_private_IIR_FIR.c: + +
    + + ) + { + silk_resampler_state_struct *S = \ +(silk_resampler_state_struct *)SS; + opus_int32 nSamplesIn; + opus_int32 max_index_Q16, index_increment_Q16; +- opus_int16 buf[ RESAMPLER_MAX_BATCH_SIZE_IN + \ +RESAMPLER_ORDER_FIR_12 ]; ++ opus_int16 buf[ 2*RESAMPLER_MAX_BATCH_SIZE_IN + \ +RESAMPLER_ORDER_FIR_12 ]; + + /* Copy buffered samples to start of buffer */ +- silk_memcpy( buf, S->sFIR, RESAMPLER_ORDER_FIR_12 \ +* sizeof( opus_int32 ) ); ++ silk_memcpy( buf, S->sFIR, RESAMPLER_ORDER_FIR_12 \ +* sizeof( opus_int16 ) ); + + /* Iterate over blocks of frameSizeIn input samples */ + index_increment_Q16 = S->invRatio_Q16; + while( 1 ) { + nSamplesIn = silk_min( inLen, S->batchSize ); + + /* Upsample 2x */ + silk_resampler_private_up2_HQ( S->sIIR, &buf[ \ +RESAMPLER_ORDER_FIR_12 ], in, nSamplesIn ); + + max_index_Q16 = silk_LSHIFT32( nSamplesIn, 16 + 1 \ +); /* + 1 because 2x upsampling */ + out = silk_resampler_private_IIR_FIR_INTERPOL( out, \ +buf, max_index_Q16, index_increment_Q16 ); + in += nSamplesIn; + inLen -= nSamplesIn; + + if( inLen > 0 ) { + /* More iterations to do; copy last part of \ +filtered signal to beginning of buffer */ +- silk_memcpy( buf, &buf[ nSamplesIn << 1 ], \ +RESAMPLER_ORDER_FIR_12 * sizeof( opus_int32 ) ); ++ silk_memmove( buf, &buf[ nSamplesIn << 1 ], \ +RESAMPLER_ORDER_FIR_12 * sizeof( opus_int16 ) ); + } else { + break; + } + } + + /* Copy last part of filtered signal to the state for \ +the next call */ +- silk_memcpy( S->sFIR, &buf[ nSamplesIn << 1 ], \ +RESAMPLER_ORDER_FIR_12 * sizeof( opus_int32 ) ); ++ silk_memcpy( S->sFIR, &buf[ nSamplesIn << 1 ], \ +RESAMPLER_ORDER_FIR_12 * sizeof( opus_int16 ) ); + } + +]]> +

    + + It was discovered through decoder fuzzing that some bitstreams could produce + integer values exceeding 32-bits in LPC_inverse_pred_gain_QA(), causing + a wrap-around. The C standard considers + this behavior as undefined. The following patch to line 87 of silk/LPC_inv_pred_gain.c + detects values that do not fit in a 32-bit integer and considers the corresponding filters unstable: + +
    + + /* Update AR coefficient */ + for( n = 0; n < k; n++ ) { +- tmp_QA = Aold_QA[ n ] - MUL32_FRAC_Q( \ +Aold_QA[ k - n - 1 ], rc_Q31, 31 ); +- Anew_QA[ n ] = MUL32_FRAC_Q( tmp_QA, rc_mult2 , mult2Q ); ++ opus_int64 tmp64; ++ tmp_QA = silk_SUB_SAT32( Aold_QA[ n ], MUL32_FRAC_Q( \ +Aold_QA[ k - n - 1 ], rc_Q31, 31 ) ); ++ tmp64 = silk_RSHIFT_ROUND64( silk_SMULL( tmp_QA, \ +rc_mult2 ), mult2Q); ++ if( tmp64 > silk_int32_MAX || tmp64 < silk_int32_MIN ) { ++ return 0; ++ } ++ Anew_QA[ n ] = ( opus_int32 )tmp64; + } + +]]> +
    +
    + +
    + + It was discovered -- also from decoder fuzzing -- that an integer wrap-around could + occur when decoding bitstreams with extremely large values for the high LSF parameters. + The end result of the wrap-around is an illegal read access on the stack, which + the authors do not believe is exploitable but should nonetheless be fixed. The following + patch to line 137 of silk/NLSF_stabilize.c prevents the problem: + +
    + + /* Keep delta_min distance between the NLSFs */ + for( i = 1; i < L; i++ ) +- NLSF_Q15[i] = silk_max_int( NLSF_Q15[i], \ +NLSF_Q15[i-1] + NDeltaMin_Q15[i] ); ++ NLSF_Q15[i] = silk_max_int( NLSF_Q15[i], \ +silk_ADD_SAT16( NLSF_Q15[i-1], NDeltaMin_Q15[i] ) ); + + /* Last NLSF should be no higher than 1 - NDeltaMin[L] */ + +]]> +
    + +
    + +
    + On extreme bit-streams, it is possible for log-domain band energy levels + to exceed the maximum single-precision floating point value once converted + to a linear scale. This would later cause the decoded values to be NaN (not a number), + possibly causing problems in the software using the PCM values. This can be + avoided with the following patch to line 552 of celt/quant_bands.c: + +
    + + { + opus_val16 lg = ADD16(oldEBands[i+c*m->nbEBands], + SHL16((opus_val16)eMeans[i],6)); ++ lg = MIN32(QCONST32(32.f, 16), lg); + eBands[i+c*m->nbEBands] = PSHR32(celt_exp2(lg),4); + } + for (;inbEBands;i++) + +]]> +

    + When encoding in hybrid mode at low bitrate, we sometimes only have + enough bits to code a single CELT band (8 - 9.6 kHz). When that happens, + the second band (CELT band 18, from 9.6 to 12 kHz) cannot use folding + because it is wider than the amount already coded, and falls back to + white noise. Because it can also happen on transients (e.g. stops), it + can cause audible pre-echo. + + + To address the issue, we change the folding behavior so that it is + never forced to fall back to LCG due to the first band not containing + enough coefficients to fold onto the second band. This + is achieved by simply repeating part of the first band in the folding + of the second band. This changes the code in celt/bands.c around line 1237: + +

    + + The fix does not impact compatibility, because the improvement does + not depend on the encoder doing anything special. There is also no + reasonable way for an encoder to use the original behavior to + improve quality over the proposed change. + +
    + +
    + The last issue is not strictly a bug, but it is an issue that has been reported + when downmixing an Opus decoded stream to mono, whether this is done inside the decoder + or as a post-processing step on the stereo decoder output. Opus intensity stereo allows + optionally coding the two channels 180-degrees out of phase on a per-band basis. + This provides better stereo quality than forcing the two channels to be in phase, + but when the output is downmixed to mono, the energy in the affected bands is cancelled + sometimes resulting in audible artifacts. + + As a work-around for this issue, the decoder MAY choose not to apply the 180-degree + phase shift. This can be useful when downmixing to mono inside or + outside of the decoder (e.g. user-controllable). + +

    +     + + + +General + + + + + +This document defines the Opus interactive speech and audio codec. +Opus is designed to handle a wide range of interactive audio applications, + including Voice over IP, videoconferencing, in-game chat, and even live, + distributed music performances. +It scales from low bitrate narrowband speech at 6 kb/s to very high quality + stereo music at 510 kb/s. +Opus uses both linear prediction (LP) and the Modified Discrete Cosine + Transform (MDCT) to achieve good compression of both speech and music. + + +     + + + +
    + +The Opus codec is a real-time interactive audio codec designed to meet the requirements +described in . +It is composed of a linear + prediction (LP)-based layer and a Modified Discrete Cosine Transform + (MDCT)-based layer. +The main idea behind using two layers is that in speech, linear prediction + techniques (such as Code-Excited Linear Prediction, or CELP) code low frequencies more efficiently than transform + (e.g., MDCT) domain techniques, while the situation is reversed for music and + higher speech frequencies. +Thus a codec with both layers available can operate over a wider range than + either one alone and, by combining them, achieve better quality than either + one individually. + + + +The primary normative part of this specification is provided by the source code + in . +Only the decoder portion of this software is normative, though a + significant amount of code is shared by both the encoder and decoder. + provides a decoder conformance test. +The decoder contains a great deal of integer and fixed-point arithmetic which + needs to be performed exactly, including all rounding considerations, so any + useful specification requires domain-specific symbolic language to adequately + define these operations. +Additionally, any +conflict between the symbolic representation and the included reference +implementation must be resolved. For the practical reasons of compatibility and +testability it would be advantageous to give the reference implementation +priority in any disagreement. The C language is also one of the most +widely understood human-readable symbolic representations for machine +behavior. +For these reasons this RFC uses the reference implementation as the sole + symbolic representation of the codec. + + +While the symbolic representation is unambiguous and complete it is not +always the easiest way to understand the codec's operation. For this reason +this document also describes significant parts of the codec in English and +takes the opportunity to explain the rationale behind many of the more +surprising elements of the design. These descriptions are intended to be +accurate and informative, but the limitations of common English sometimes +result in ambiguity, so it is expected that the reader will always read +them alongside the symbolic representation. Numerous references to the +implementation are provided for this purpose. The descriptions sometimes +differ from the reference in ordering or through mathematical simplification +wherever such deviation makes an explanation easier to understand. +For example, the right shift and left shift operations in the reference +implementation are often described using division and multiplication in the text. +In general, the text is focused on the "what" and "why" while the symbolic +representation most clearly provides the "how". + + +
    + +The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", + "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be + interpreted as described in RFC 2119 . + + +Various operations in the codec require bit-exact fixed-point behavior, even + when writing a floating point implementation. +The notation "Q<n>", where n is an integer, denotes the number of binary + digits to the right of the decimal point in a fixed-point number. +For example, a signed Q14 value in a 16-bit word can represent values from + -2.0 to 1.99993896484375, inclusive. +This notation is for informational purposes only. +Arithmetic, when described, always operates on the underlying integer. +E.g., the text will explicitly indicate any shifts required after a + multiplication. + + +Expressions, where included in the text, follow C operator rules and + precedence, with the exception that the syntax "x**y" indicates x raised to + the power y. +The text also makes use of the following functions: + + +
    + +The smallest of two values x and y. + +

    + +
    + + +The Opus codec scales from 6 kb/s narrowband mono speech to 510 kb/s + fullband stereo music, with algorithmic delays ranging from 5 ms to + 65.2 ms. +At any given time, either the LP layer, the MDCT layer, or both, may be active. +It can seamlessly switch between all of its various operating modes, giving it + a great deal of flexibility to adapt to varying content and network + conditions without renegotiating the current session. +The codec allows input and output of various audio bandwidths, defined as + follows: + + +Abbreviation +Audio Bandwidth +Sample Rate (Effective) +NB (narrowband) 4 kHz 8 kHz +MB (medium-band) 6 kHz 12 kHz +WB (wideband) 8 kHz 16 kHz +SWB (super-wideband) 12 kHz 24 kHz +FB (fullband) 20 kHz (*) 48 kHz + + +(*) Although the sampling theorem allows a bandwidth as large as half the + sampling rate, Opus never codes audio above 20 kHz, as that is the + generally accepted upper limit of human hearing. + + + +Opus defines super-wideband (SWB) with an effective sample rate of 24 kHz, + unlike some other audio coding standards that use 32 kHz. +This was chosen for a number of reasons. +The band layout in the MDCT layer naturally allows skipping coefficients for + frequencies over 12 kHz, but does not allow cleanly dropping just those + frequencies over 16 kHz. +A sample rate of 24 kHz also makes resampling in the MDCT layer easier, + as 24 evenly divides 48, and when 24 kHz is sufficient, it can save + computation in other processing, such as Acoustic Echo Cancellation (AEC). +Experimental changes to the band layout to allow a 16 kHz cutoff + (32 kHz effective sample rate) showed potential quality degradations at + other sample rates, and at typical bitrates the number of bits saved by using + such a cutoff instead of coding in fullband (FB) mode is very small. +Therefore, if an application wishes to process a signal sampled at 32 kHz, + it should just use FB. + + + +The LP layer is based on the SILK codec + . +It supports NB, MB, or WB audio and frame sizes from 10 ms to 60 ms, + and requires an additional 5 ms look-ahead for noise shaping estimation. +A small additional delay (up to 1.5 ms) may be required for sampling rate + conversion. +Like Vorbis and many other modern codecs, SILK is inherently designed for + variable-bitrate (VBR) coding, though the encoder can also produce + constant-bitrate (CBR) streams. +The version of SILK used in Opus is substantially modified from, and not + compatible with, the stand-alone SILK codec previously deployed by Skype. +This document does not serve to define that format, but those interested in the + original SILK codec should see instead. + + + +The MDCT layer is based on the CELT codec . +It supports NB, WB, SWB, or FB audio and frame sizes from 2.5 ms to + 20 ms, and requires an additional 2.5 ms look-ahead due to the + overlapping MDCT windows. +The CELT codec is inherently designed for CBR coding, but unlike many CBR + codecs it is not limited to a set of predetermined rates. +It internally allocates bits to exactly fill any given target budget, and an + encoder can produce a VBR stream by varying the target on a per-frame basis. +The MDCT layer is not used for speech when the audio bandwidth is WB or less, + as it is not useful there. +On the other hand, non-speech signals are not always adequately coded using + linear prediction, so for music only the MDCT layer should be used. + + + +A "Hybrid" mode allows the use of both layers simultaneously with a frame size + of 10 or 20 ms and a SWB or FB audio bandwidth. +The LP layer codes the low frequencies by resampling the signal down to WB. +The MDCT layer follows, coding the high frequency portion of the signal. +The cutoff between the two lies at 8 kHz, the maximum WB audio bandwidth. +In the MDCT layer, all bands below 8 kHz are discarded, so there is no + coding redundancy between the two layers. + + + +The sample rate (in contrast to the actual audio bandwidth) can be chosen + independently on the encoder and decoder side, e.g., a fullband signal can be + decoded as wideband, or vice versa. +This approach ensures a sender and receiver can always interoperate, regardless + of the capabilities of their actual audio hardware. +Internally, the LP layer always operates at a sample rate of twice the audio + bandwidth, up to a maximum of 16 kHz, which it continues to use for SWB + and FB. +The decoder simply resamples its output to support different sample rates. +The MDCT layer always operates internally at a sample rate of 48 kHz. +Since all the supported sample rates evenly divide this rate, and since the + the decoder may easily zero out the high frequency portion of the spectrum in + the frequency domain, it can simply decimate the MDCT layer output to achieve + the other supported sample rates very cheaply. + + + +After conversion to the common, desired output sample rate, the decoder simply + adds the output from the two layers together. +To compensate for the different look-ahead required by each layer, the CELT + encoder input is delayed by an additional 2.7 ms. +This ensures that low frequencies and high frequencies arrive at the same time. +This extra delay may be reduced by an encoder by using less look-ahead for noise + shaping or using a simpler resampler in the LP layer, but this will reduce + quality. +However, the base 2.5 ms look-ahead in the CELT layer cannot be reduced in + the encoder because it is needed for the MDCT overlap, whose size is fixed by + the decoder. + + + +Both layers use the same entropy coder, avoiding any waste from "padding bits" + between them. +The hybrid approach makes it easy to support both CBR and VBR coding. +Although the LP layer is VBR, the bit allocation of the MDCT layer can produce + a final stream that is CBR by using all the bits left unused by the LP layer. + + +
    + +The Opus codec includes a number of control parameters which can be changed dynamically during +regular operation of the codec, without interrupting the audio stream from the encoder to the decoder. +These parameters only affect the encoder since any impact they have on the bit-stream is signaled +in-band such that a decoder can decode any Opus stream without any out-of-band signaling. Any Opus +implementation can add or modify these control parameters without affecting interoperability. The most +important encoder control parameters in the reference encoder are listed below. + + +
    + +Opus supports all bitrates from 6 kb/s to 510 kb/s. All other parameters being +equal, higher bitrate results in higher quality. For a frame size of 20 ms, these +are the bitrate "sweet spots" for Opus in various configurations: + +8-12 kb/s for NB speech, +16-20 kb/s for WB speech, +28-40 kb/s for FB speech, +48-64 kb/s for FB mono music, and +64-128 kb/s for FB stereo music. + + +
    + +
    + +Opus can transmit either mono or stereo frames within a single stream. +When decoding a mono frame in a stereo decoder, the left and right channels are + identical, and when decoding a stereo frame in a mono decoder, the mono output + is the average of the left and right channels. +In some cases, it is desirable to encode a stereo input stream in mono (e.g., + because the bitrate is too low to encode stereo with sufficient quality). +The number of channels encoded can be selected in real-time, but by default the + reference encoder attempts to make the best decision possible given the + current bitrate. + +
    + +
    + +The audio bandwidths supported by Opus are listed in + . +Just like for the number of channels, any decoder can decode audio encoded at + any bandwidth. +For example, any Opus decoder operating at 8 kHz can decode a FB Opus + frame, and any Opus decoder operating at 48 kHz can decode a NB frame. +Similarly, the reference encoder can take a 48 kHz input signal and + encode it as NB. +The higher the audio bandwidth, the higher the required bitrate to achieve + acceptable quality. +The audio bandwidth can be explicitly specified in real-time, but by default + the reference encoder attempts to make the best bandwidth decision possible + given the current bitrate. + +
    + + +
    + +Opus can encode frames of 2.5, 5, 10, 20, 40 or 60 ms. +It can also combine multiple frames into packets of up to 120 ms. +For real-time applications, sending fewer packets per second reduces the + bitrate, since it reduces the overhead from IP, UDP, and RTP headers. +However, it increases latency and sensitivity to packet losses, as losing one + packet constitutes a loss of a bigger chunk of audio. +Increasing the frame duration also slightly improves coding efficiency, but the + gain becomes small for frame sizes above 20 ms. +For this reason, 20 ms frames are a good choice for most applications. + +
    + +
    + +There are various aspects of the Opus encoding process where trade-offs +can be made between CPU complexity and quality/bitrate. In the reference +encoder, the complexity is selected using an integer from 0 to 10, where +0 is the lowest complexity and 10 is the highest. Examples of +computations for which such trade-offs may occur are: + +The order of the pitch analysis whitening filter , +The order of the short-term noise shaping filter, +The number of states in delayed decision quantization of the +residual signal, and +The use of certain bit-stream features such as variable time-frequency +resolution and the pitch post-filter. + + +
    + +
    + +Audio codecs often exploit inter-frame correlations to reduce the +bitrate at a cost in error propagation: after losing one packet +several packets need to be received before the decoder is able to +accurately reconstruct the speech signal. The extent to which Opus +exploits inter-frame dependencies can be adjusted on the fly to +choose a trade-off between bitrate and amount of error propagation. + +
    + +
    + + Another mechanism providing robustness against packet loss is the in-band + Forward Error Correction (FEC). Packets that are determined to + contain perceptually important speech information, such as onsets or + transients, are encoded again at a lower bitrate and this re-encoded + information is added to a subsequent packet. + +
    + +
    + +Opus is more efficient when operating with variable bitrate (VBR), which is +the default. However, in some (rare) applications, constant bitrate (CBR) +is required. There are two main reasons to operate in CBR mode: + +When the transport only supports a fixed size for each compressed frame +When encryption is used for an audio stream that is either highly constrained + (e.g. yes/no, recorded prompts) or highly sensitive + + +When low-latency transmission is required over a relatively slow connection, then +constrained VBR can also be used. This uses VBR in a way that simulates a +"bit reservoir" and is equivalent to what MP3 (MPEG 1, Layer 3) and +AAC (Advanced Audio Coding) call CBR (i.e., not true +CBR due to the bit reservoir). + +
    + +
    + + Discontinuous Transmission (DTX) reduces the bitrate during silence + or background noise. When DTX is enabled, only one frame is encoded + every 400 milliseconds. + +
    + +
    + +
    + +
    + + +The Opus encoder produces "packets", which are each a contiguous set of bytes + meant to be transmitted as a single unit. +The packets described here do not include such things as IP, UDP, or RTP + headers which are normally found in a transport-layer packet. +A single packet may contain multiple audio frames, so long as they share a + common set of parameters, including the operating mode, audio bandwidth, frame + size, and channel count (mono vs. stereo). +This section describes the possible combinations of these parameters and the + internal framing used to pack multiple frames into a single packet. +This framing is not self-delimiting. +Instead, it assumes that a higher layer (such as UDP or RTP +or Ogg or Matroska ) + will communicate the length, in bytes, of the packet, and it uses this + information to reduce the framing overhead in the packet itself. +A decoder implementation MUST support the framing described in this section. +An alternative, self-delimiting variant of the framing is described in + . +Support for that variant is OPTIONAL. + + + +All bit diagrams in this document number the bits so that bit 0 is the most + significant bit of the first byte, and bit 7 is the least significant. +Bit 8 is thus the most significant bit of the second byte, etc. +Well-formed Opus packets obey certain requirements, marked [R1] through [R7] + below. +These are summarized in along with + appropriate means of handling malformed packets. + + +
    + +A well-formed Opus packet MUST contain at least one byte [R1]. +This byte forms a table-of-contents (TOC) header that signals which of the + various modes and configurations a given packet uses. +It is composed of a configuration number, "config", a stereo flag, "s", and a + frame count code, "c", arranged as illustrated in + . +A description of each of these fields follows. + + +
    + +
    + + +The top five bits of the TOC byte, labeled "config", encode one of 32 possible + configurations of operating mode, audio bandwidth, and frame size. +As described, the LP (SILK) layer and MDCT (CELT) layer can be combined in three possible + operating modes: + +A SILK-only mode for use in low bitrate connections with an audio bandwidth + of WB or less, +A Hybrid (SILK+CELT) mode for SWB or FB speech at medium bitrates, and +A CELT-only mode for very low delay speech transmission as well as music + transmission (NB to FB). + +The 32 possible configurations each identify which one of these operating modes + the packet uses, as well as the audio bandwidth and the frame size. + lists the parameters for each configuration. + + +Configuration Number(s) +Mode +Bandwidth +Frame Sizes +0...3 SILK-only NB 10, 20, 40, 60 ms +4...7 SILK-only MB 10, 20, 40, 60 ms +8...11 SILK-only WB 10, 20, 40, 60 ms +12...13 Hybrid SWB 10, 20 ms +14...15 Hybrid FB 10, 20 ms +16...19 CELT-only NB 2.5, 5, 10, 20 ms +20...23 CELT-only WB 2.5, 5, 10, 20 ms +24...27 CELT-only SWB 2.5, 5, 10, 20 ms +28...31 CELT-only FB 2.5, 5, 10, 20 ms + + +The configuration numbers in each range (e.g., 0...3 for NB SILK-only) + correspond to the various choices of frame size, in the same order. +For example, configuration 0 has a 10 ms frame size and configuration 3 + has a 60 ms frame size. + + + +One additional bit, labeled "s", signals mono vs. stereo, with 0 indicating + mono and 1 indicating stereo. + + + +The remaining two bits of the TOC byte, labeled "c", code the number of frames + per packet (codes 0 to 3) as follows: + +0: 1 frame in the packet +1: 2 frames in the packet, each with equal compressed size +2: 2 frames in the packet, with different compressed sizes +3: an arbitrary number of frames in the packet + +This draft refers to a packet as a code 0 packet, code 1 packet, etc., based on + the value of "c". + + +
    + +
    + + +This section describes how frames are packed according to each possible value + of "c" in the TOC byte. + + +
    + +When a packet contains multiple VBR frames (i.e., code 2 or 3), the compressed + length of one or more of these frames is indicated with a one- or two-byte + sequence, with the meaning of the first byte as follows: + +0: No frame (discontinuous transmission (DTX) or lost packet) +1...251: Length of the frame in bytes +252...255: A second byte is needed. The total length is (second_byte*4)+first_byte + + + + +The special length 0 indicates that no frame is available, either because it + was dropped during transmission by some intermediary or because the encoder + chose not to transmit it. +Any Opus frame in any mode MAY have a length of 0. + + + +The maximum representable length is 255*4+255=1275 bytes. +For 20 ms frames, this represents a bitrate of 510 kb/s, which is + approximately the highest useful rate for lossily compressed fullband stereo + music. +Beyond this point, lossless codecs are more appropriate. +It is also roughly the maximum useful rate of the MDCT layer, as shortly + thereafter quality no longer improves with additional bits due to limitations + on the codebook sizes. + + + +No length is transmitted for the last frame in a VBR packet, or for any of the + frames in a CBR packet, as it can be inferred from the total size of the + packet and the size of all other data in the packet. +However, the length of any individual frame MUST NOT exceed + 1275 bytes [R2], to allow for repacketization by gateways, + conference bridges, or other software. + +
    + +
    + + +For code 0 packets, the TOC byte is immediately followed by N-1 bytes + of compressed data for a single frame (where N is the size of the packet), + as illustrated in . + +
    + +
    +
    + +
    + +For code 1 packets, the TOC byte is immediately followed by the + (N-1)/2 bytes of compressed data for the first frame, followed by + (N-1)/2 bytes of compressed data for the second frame, as illustrated in + . +The number of payload bytes available for compressed data, N-1, MUST be even + for all code 1 packets [R3]. + +
    + +
    +
    + +
    + +For code 2 packets, the TOC byte is followed by a one- or two-byte sequence + indicating the length of the first frame (marked N1 in ), + followed by N1 bytes of compressed data for the first frame. +The remaining N-N1-2 or N-N1-3 bytes are the compressed data for the + second frame. +This is illustrated in . +A code 2 packet MUST contain enough bytes to represent a valid length. +For example, a 1-byte code 2 packet is always invalid, and a 2-byte code 2 + packet whose second byte is in the range 252...255 is also invalid. +The length of the first frame, N1, MUST also be no larger than the size of the + payload remaining after decoding that length for all code 2 packets [R4]. +This makes, for example, a 2-byte code 2 packet with a second byte in the range + 1...251 invalid as well (the only valid 2-byte code 2 packet is one where the + length of both frames is zero). + +
    + +

    + +Code 3 packets signal the number of frames, as well as additional + padding, called "Opus padding" to indicate that this padding is added at the + Opus layer, rather than at the transport layer. +Code 3 packets MUST have at least 2 bytes [R6,R7]. +The TOC byte is followed by a byte encoding the number of frames in the packet + in bits 2 to 7 (marked "M" in ), with bit 1 indicating whether + or not Opus padding is inserted (marked "p" in ), and bit 0 + indicating VBR (marked "v" in ). +M MUST NOT be zero, and the audio duration contained within a packet MUST NOT + exceed 120 ms [R5]. +This limits the maximum frame count for any frame size to 48 (for 2.5 ms + frames), with lower limits for longer frame sizes. + illustrates the layout of the frame count + byte. + +
    + +
    + +When Opus padding is used, the number of bytes of padding is encoded in the + bytes following the frame count byte. +Values from 0...254 indicate that 0...254 bytes of padding are included, + in addition to the byte(s) used to indicate the size of the padding. +If the value is 255, then the size of the additional padding is 254 bytes, + plus the padding value encoded in the next byte. +There MUST be at least one more byte in the packet in this case [R6,R7]. +The additional padding bytes appear at the end of the packet, and MUST be set + to zero by the encoder to avoid creating a covert channel. +The decoder MUST accept any value for the padding bytes, however. + + +Although this encoding provides multiple ways to indicate a given number of + padding bytes, each uses a different number of bytes to indicate the padding + size, and thus will increase the total packet size by a different amount. +For example, to add 255 bytes to a packet, set the padding bit, p, to 1, insert + a single byte after the frame count byte with a value of 254, and append 254 + padding bytes with the value zero to the end of the packet. +To add 256 bytes to a packet, set the padding bit to 1, insert two bytes after + the frame count byte with the values 255 and 0, respectively, and append 254 + padding bytes with the value zero to the end of the packet. +By using the value 255 multiple times, it is possible to create a packet of any + specific, desired size. +Let P be the number of header bytes used to indicate the padding size plus the + number of padding bytes themselves (i.e., P is the total number of bytes added + to the packet). +Then P MUST be no more than N-2 [R6,R7]. + + +In the CBR case, let R=N-2-P be the number of bytes remaining in the packet + after subtracting the (optional) padding. +Then the compressed length of each frame in bytes is equal to R/M. +The value R MUST be a non-negative integer multiple of M [R6]. +The compressed data for all M frames follows, each of size + R/M bytes, as illustrated in . + + +
    + +
    + + +In the VBR case, the (optional) padding length is followed by M-1 frame + lengths (indicated by "N1" to "N[M-1]" in ), each encoded in a + one- or two-byte sequence as described above. +The packet MUST contain enough data for the M-1 lengths after removing the + (optional) padding, and the sum of these lengths MUST be no larger than the + number of bytes remaining in the packet after decoding them [R7]. +The compressed data for all M frames follows, each frame consisting of the + indicated number of bytes, with the final frame consuming any remaining bytes + before the final padding, as illustrated in . +The number of header bytes (TOC byte, frame count byte, padding length bytes, + and frame length bytes), plus the signaled length of the first M-1 frames themselves, + plus the signaled length of the padding MUST be no larger than N, the total size of the + packet. + + +

    + +A receiver MUST NOT process packets which violate any of the rules above as + normal Opus packets. +They are reserved for future applications, such as in-band headers (containing + metadata, etc.). +Packets which violate these constraints may cause implementations of + this specification to treat them as malformed, and + discard them. + + +These constraints are summarized here for reference: + +Packets are at least one byte. +No implicit frame length is larger than 1275 bytes. +Code 1 packets have an odd total length, N, so that (N-1)/2 is an + integer. +Code 2 packets have enough bytes after the TOC for a valid frame + length, and that length is no larger than the number of bytes remaining in the + packet. +Code 3 packets contain at least one frame, but no more than 120 ms + of audio total. +The length of a CBR code 3 packet, N, is at least two bytes, the number of + bytes added to indicate the padding size plus the trailing padding bytes + themselves, P, is no more than N-2, and the frame count, M, satisfies + the constraint that (N-2-P) is a non-negative integer multiple of M. +VBR code 3 packets are large enough to contain all the header bytes (TOC + byte, frame count byte, any padding length bytes, and any frame length bytes), + plus the length of the first M-1 frames, plus any trailing padding bytes. + + +

    + +The Opus decoder consists of two main blocks: the SILK decoder and the CELT + decoder. +At any given time, one or both of the SILK and CELT decoders may be active. +The output of the Opus decode is the sum of the outputs from the SILK and CELT + decoders with proper sample rate conversion and delay compensation on the SILK + side, and optional decimation (when decoding to sample rates less than + 48 kHz) on the CELT side, as illustrated in the block diagram below. + +

    + +Opus uses an entropy coder based on range coding +, +which is itself a rediscovery of the FIFO arithmetic code introduced by . +It is very similar to arithmetic encoding, except that encoding is done with +digits in any base instead of with bits, +so it is faster when using larger bases (i.e., a byte). All of the +calculations in the range coder must use bit-exact integer arithmetic. + + +Symbols may also be coded as "raw bits" packed directly into the bitstream, + bypassing the range coder. +These are packed backwards starting at the end of the frame, as illustrated in + . +This reduces complexity and makes the stream more resilient to bit errors, as + corruption in the raw bits will not desynchronize the decoding process, unlike + corruption in the input to the range decoder. +Raw bits are only used in the CELT layer. + + +

    + + +Each symbol coded by the range coder is drawn from a finite alphabet and coded + in a separate "context", which describes the size of the alphabet and the + relative frequency of each symbol in that alphabet. + + +Suppose there is a context with n symbols, identified with an index that ranges + from 0 to n-1. +The parameters needed to encode or decode symbol k in this context are + represented by a three-tuple (fl[k], fh[k], ft), with + 0 <= fl[k] < fh[k] <= ft <= 65535. +The values of this tuple are derived from the probability model for the + symbol, represented by traditional "frequency counts". +Because Opus uses static contexts these are not updated as symbols are decoded. +Let f[i] be the frequency of symbol i. +Then the three-tuple corresponding to symbol k is given by + +
    + +
    + +The range decoder extracts the symbols and integers encoded using the range + encoder in . +The range decoder maintains an internal state vector composed of the two-tuple + (val, rng), representing the difference between the high end of the + current range and the actual coded value, minus one, and the size of the + current range, respectively. +Both val and rng are 32-bit unsigned integer values. + + +
    + +Let b0 be the first input byte (or zero if there are no bytes in this Opus + frame). +The decoder initializes rng to 128 and initializes val to + (127 - (b0>>1)), where (b0>>1) is the top 7 bits of the + first input byte. +It saves the remaining bit, (b0&1), for use in the renormalization + procedure described in , which the + decoder invokes immediately after initialization to read additional bits and + establish the invariant that rng > 2**23. + +
    + +
    + +Decoding a symbol is a two-step process. +The first step determines a 16-bit unsigned value fs, which lies within the + range of some symbol in the current context. +The second step updates the range decoder state with the three-tuple + (fl[k], fh[k], ft) corresponding to that symbol. + + +The first step is implemented by ec_decode() (entdec.c), which computes +
    + +
    +The divisions here are integer division. +     + +The decoder then identifies the symbol in the current context corresponding to + fs; i.e., the value of k whose three-tuple (fl[k], fh[k], ft) + satisfies fl[k] <= fs < fh[k]. +It uses this tuple to update val according to +
    + +
    +If fl[k] is greater than zero, then the decoder updates rng using +
    + +
    +Otherwise, it updates rng using +
    + +
    +     + +Using a special case for the first symbol (rather than the last symbol, as is + commonly done in other arithmetic coders) ensures that all the truncation + error from the finite precision arithmetic accumulates in symbol 0. +This makes the cost of coding a 0 slightly smaller, on average, than its + estimated probability indicates and makes the cost of coding any other symbol + slightly larger. +When contexts are designed so that 0 is the most probable symbol, which is + often the case, this strategy minimizes the inefficiency introduced by the + finite precision. +It also makes some of the special-case decoding routines in + particularly simple. + + +After the updates, implemented by ec_dec_update() (entdec.c), the decoder + normalizes the range using the procedure in the next section, and returns the + index k. + + +
    + +To normalize the range, the decoder repeats the following process, implemented + by ec_dec_normalize() (entdec.c), until rng > 2**23. +If rng is already greater than 2**23, the entire process is skipped. +First, it sets rng to (rng<<8). +Then it reads the next byte of the Opus frame and forms an 8-bit value sym, + using the left-over bit buffered from the previous byte as the high bit + and the top 7 bits of the byte just read as the other 7 bits of sym. +The remaining bit in the byte just read is buffered for use in the next + iteration. +If no more input bytes remain, it uses zero bits instead. +See for the initialization used to process + the first byte. +Then, it sets +
    + +
    +     + +It is normal and expected that the range decoder will read several bytes + into the raw bits data (if any) at the end of the packet by the time the frame + is completely decoded, as illustrated in . +This same data MUST also be returned as raw bits when requested. +The encoder is expected to terminate the stream in such a way that the decoder + will decode the intended values regardless of the data contained in the raw + bits. + describes a procedure for doing this. +If the range decoder consumes all of the bytes belonging to the current frame, + it MUST continue to use zero when any further input bytes are required, even + if there is additional data in the current packet from padding or other + frames. + + +

    +
    + +
    + +The reference implementation uses three additional decoding methods that are + exactly equivalent to the above, but make assumptions and simplifications that + allow for a more efficient implementation. + +
    + +The first is ec_decode_bin() (entdec.c), defined using the parameter ftb + instead of ft. +It is mathematically equivalent to calling ec_decode() with + ft = (1<<ftb), but avoids one of the divisions. + +
    +
    + +The next is ec_dec_bit_logp() (entdec.c), which decodes a single binary symbol, + replacing both the ec_decode() and ec_dec_update() steps. +The context is described by a single parameter, logp, which is the absolute + value of the base-2 logarithm of the probability of a "1". +It is mathematically equivalent to calling ec_decode() with + ft = (1<<logp), followed by ec_dec_update() with + the 3-tuple (fl[k] = 0, + fh[k] = (1<<logp) - 1, + ft = (1<<logp)) if the returned value + of fs is less than (1<<logp) - 1 (a "0" was decoded), and with + (fl[k] = (1<<logp) - 1, + fh[k] = ft = (1<<logp)) otherwise (a "1" was + decoded). +The implementation requires no multiplications or divisions. + +
    +
    + +The last is ec_dec_icdf() (entdec.c), which decodes a single symbol with a + table-based context of up to 8 bits, also replacing both the ec_decode() and + ec_dec_update() steps, as well as the search for the decoded symbol in between. +The context is described by two parameters, an icdf + ("inverse" cumulative distribution function) table and ftb. +As with ec_decode_bin(), (1<<ftb) is equivalent to ft. +idcf[k], on the other hand, stores (1<<ftb)-fh[k], which is equal to + (1<<ftb) - fl[k+1]. +fl[0] is assumed to be 0, and the table is terminated by a value of 0 (where + fh[k] == ft). + + +The function is mathematically equivalent to calling ec_decode() with + ft = (1<<ftb), using the returned value fs to search the table + for the first entry where fs < (1<<ftb)-icdf[k], and + calling ec_dec_update() with + fl[k] = (1<<ftb) - icdf[k-1] (or 0 + if k == 0), fh[k] = (1<<ftb) - idcf[k], + and ft = (1<<ftb). +Combining the search with the update allows the division to be replaced by a + series of multiplications (which are usually much cheaper), and using an + inverse CDF allows the use of an ftb as large as 8 in an 8-bit table without + any special cases. +This is the primary interface with the range decoder in the SILK layer, though + it is used in a few places in the CELT layer as well. + + +Although icdf[k] is more convenient for the code, the frequency counts, f[k], + are a more natural representation of the probability distribution function + (PDF) for a given symbol. +Therefore this draft lists the latter, not the former, when describing the + context in which a symbol is coded as a list, e.g., {4, 4, 4, 4}/16 for a + uniform context with four possible values and ft = 16. +The value of ft after the slash is always the sum of the entries in the PDF, + but is included for convenience. +Contexts with identical probabilities, f[k]/ft, but different values of ft + (or equivalently, ftb) are not the same, and cannot, in general, be used in + place of one another. +An icdf table is also not capable of representing a PDF where the first symbol + has 0 probability. +In such contexts, ec_dec_icdf() can decode the symbol by using a table that + drops the entries for any initial zero-probability values and adding the + constant offset of the first value with a non-zero probability to its return + value. + +
    +
    + +
    + +The raw bits used by the CELT layer are packed at the end of the packet, with + the least significant bit of the first value packed in the least significant + bit of the last byte, filling up to the most significant bit in the last byte, + continuing on to the least significant bit of the penultimate byte, and so on. +The reference implementation reads them using ec_dec_bits() (entdec.c). +Because the range decoder must read several bytes ahead in the stream, as + described in , the input consumed by the + raw bits may overlap with the input consumed by the range coder, and a decoder + MUST allow this. +The format should render it impossible to attempt to read more raw bits than + there are actual bits in the frame, though a decoder may wish to check for + this and report an error. + +
    + +
    + +The function ec_dec_uint() (entdec.c) decodes one of ft equiprobable values in + the range 0 to (ft - 1), inclusive, each with a frequency of 1, + where ft may be as large as (2**32 - 1). +Because ec_decode() is limited to a total frequency of (2**16 - 1), + it splits up the value into a range coded symbol representing up to 8 of the + high bits, and, if necessary, raw bits representing the remainder of the + value. +The limit of 8 bits in the range coded symbol is a trade-off between + implementation complexity, modeling error (since the symbols no longer truly + have equal coding cost), and rounding error introduced by the range coder + itself (which gets larger as more bits are included). +Using raw bits reduces the maximum number of divisions required in the worst + case, but means that it may be possible to decode a value outside the range + 0 to (ft - 1), inclusive. + + + +ec_dec_uint() takes a single, positive parameter, ft, which is not necessarily + a power of two, and returns an integer, t, whose value lies between 0 and + (ft - 1), inclusive. +Let ftb = ilog(ft - 1), i.e., the number of bits required + to store (ft - 1) in two's complement notation. +If ftb is 8 or less, then t is decoded with t = ec_decode(ft), and + the range coder state is updated using the three-tuple (t, t + 1, + ft). + + +If ftb is greater than 8, then the top 8 bits of t are decoded using +
    +> (ftb - 8)) + 1) , +]]> +
    + the decoder state is updated using the three-tuple + (t, t + 1, + ((ft - 1) >> (ftb - 8)) + 1), + and the remaining bits are decoded as raw bits, setting +
    + +
    +If, at this point, t >= ft, then the current frame is corrupt. +In that case, the decoder should assume there has been an error in the coding, + decoding, or transmission and SHOULD take measures to conceal the + error and/or report to the application that the error has occurred. +     + +
    + +
    + +The bit allocation routines in the CELT decoder need a conservative upper bound + on the number of bits that have been used from the current frame thus far, + including both range coder bits and raw bits. +This drives allocation decisions that must match those made in the encoder. +The upper bound is computed in the reference implementation to whole-bit + precision by the function ec_tell() (entcode.h) and to fractional 1/8th bit + precision by the function ec_tell_frac() (entcode.c). +Like all operations in the range coder, it must be implemented in a bit-exact + manner, and must produce exactly the same value returned by the same functions + in the encoder after encoding the same symbols. + + +ec_tell() is guaranteed to return ceil(ec_tell_frac()/8.0). +In various places the codec will check to ensure there is enough room to + contain a symbol before attempting to decode it. +In practice, although the number of bits used so far is an upper bound, + decoding a symbol whose probability model suggests it has a worst-case cost of + p 1/8th bits may actually advance the return value of ec_tell_frac() by + p-1, p, or p+1 1/8th bits, due to approximation error in that upper bound, + truncation error in the range coder, and for large values of ft, modeling + error in ec_dec_uint(). + + +However, this error is bounded, and periodic calls to ec_tell() or + ec_tell_frac() at precisely defined points in the decoding process prevent it + from accumulating. +For a range coder symbol that requires a whole number of bits (i.e., + for which ft/(fh[k] - fl[k]) is a power of two), where there are at + least p 1/8th bits available, decoding the symbol will never cause ec_tell() or + ec_tell_frac() to exceed the size of the frame ("bust the budget"). +In this case the return value of ec_tell_frac() will only advance by more than + p 1/8th bits if there was an additional, fractional number of bits remaining, + and it will never advance beyond the next whole-bit boundary, which is safe, + since frames always contain a whole number of bits. +However, when p is not a whole number of bits, an extra 1/8th bit is required + to ensure that decoding the symbol will not bust the budget. + + +The reference implementation keeps track of the total number of whole bits that + have been processed by the decoder so far in the variable nbits_total, + including the (possibly fractional) number of bits that are currently + buffered, but not consumed, inside the range coder. +nbits_total is initialized to 9 just before the initial range renormalization + process completes (or equivalently, it can be initialized to 33 after the + first renormalization). +The extra two bits over the actual amount buffered by the range coder + guarantees that it is an upper bound and that there is enough room for the + encoder to terminate the stream. +Each iteration through the range coder's renormalization loop increases + nbits_total by 8. +Reading raw bits increases nbits_total by the number of raw bits read. + + +
    + +The whole number of bits buffered in rng may be estimated via lg = ilog(rng). +ec_tell() then becomes a simple matter of removing these bits from the total. +It returns (nbits_total - lg). + + +In a newly initialized decoder, before any symbols have been read, this reports + that 1 bit has been used. +This is the bit reserved for termination of the encoder. + +
    + +
    + +ec_tell_frac() estimates the number of bits buffered in rng to fractional + precision. +Since rng must be greater than 2**23 after renormalization, lg must be at least + 24. +Let +
    + +> (lg-16) , +]]> +
    + so that 32768 <= r_Q15 < 65536, an unsigned Q15 value representing the + fractional part of rng. +Then the following procedure can be used to add one bit of precision to lg. +First, update +
    + +> 15 . +]]> +
    +Then add the 16th bit of r_Q15 to lg via +
    + +> 16) . +]]> +
    +Finally, if this bit was a 1, reduce r_Q15 by a factor of two via +
    + +> 1 , +]]> +
    + so that it once again lies in the range 32768 <= r_Q15 < 65536. +     + +This procedure is repeated three times to extend lg to 1/8th bit precision. +ec_tell_frac() then returns (nbits_total*8 - lg). + +
    + +
    + +
    + +
    + +The decoder's LP layer uses a modified version of the SILK codec (herein simply + called "SILK"), which runs a decoded excitation signal through adaptive + long-term and short-term prediction synthesis filters. +It runs at NB, MB, and WB sample rates internally. +When used in a SWB or FB Hybrid frame, the LP layer itself still only runs in + WB. + + +

    + + +The decoder feeds the bitstream (1) to the range decoder from + , and then decodes the parameters in it (2) + using the procedures detailed in + Sections  + through . +These parameters (3, 4, 5) are used to generate an excitation signal (see + ), which is fed to an optional + long-term prediction (LTP) filter (voiced frames only, see + ) and then a short-term prediction filter + (see ), producing the decoded signal (6). +For stereo streams, the mid-side representation is converted to separate left + and right channels (7). +The result is finally resampled to the desired output sample rate (e.g., + 48 kHz) so that the resampled signal (8) can be mixed with the CELT + layer. + + +
    + +
    + + +Internally, the LP layer of a single Opus frame is composed of either a single + 10 ms regular SILK frame or between one and three 20 ms regular SILK + frames. +A stereo Opus frame may double the number of regular SILK frames (up to a total + of six), since it includes separate frames for a mid channel and, optionally, + a side channel. +Optional Low Bit-Rate Redundancy (LBRR) frames, which are reduced-bitrate + encodings of previous SILK frames, may be included to aid in recovery from + packet loss. +If present, these appear before the regular SILK frames. +They are in most respects identical to regular, active SILK frames, except that + they are usually encoded with a lower bitrate. +This draft uses "SILK frame" to refer to either one and "regular SILK frame" if + it needs to draw a distinction between the two. + + +Logically, each SILK frame is in turn composed of either two or four 5 ms + subframes. +Various parameters, such as the quantization gain of the excitation and the + pitch lag and filter coefficients can vary on a subframe-by-subframe basis. +Physically, the parameters for each subframe are interleaved in the bitstream, + as described in the relevant sections for each parameter. + + +All of these frames and subframes are decoded from the same range coder, with + no padding between them. +Thus packing multiple SILK frames in a single Opus frame saves, on average, + half a byte per SILK frame. +It also allows some parameters to be predicted from prior SILK frames in the + same Opus frame, since this does not degrade packet loss robustness (beyond + any penalty for merely using fewer, larger packets to store multiple frames). + + + +Stereo support in SILK uses a variant of mid-side coding, allowing a mono + decoder to simply decode the mid channel. +However, the data for the two channels is interleaved, so a mono decoder must + still unpack the data for the side channel. +It would be required to do so anyway for Hybrid Opus frames, or to support + decoding individual 20 ms frames. + + + + summarizes the overall grouping of the contents of + the LP layer. +Figures  + and  illustrate + the ordering of the various SILK frames for a 60 ms Opus frame, for both + mono and stereo, respectively. + + + +Symbol(s) +PDF(s) +Condition + +Voice Activity Detection (VAD) flags +{1, 1}/2 + + +LBRR flag +{1, 1}/2 + + +Per-frame LBRR flags + + + +LBRR Frame(s) + + + +Regular SILK Frame(s) + + + + + +

    + +The LP layer begins with two to eight header bits, decoded in silk_Decode() + (dec_API.c). +These consist of one Voice Activity Detection (VAD) bit per frame (up to 3), + followed by a single flag indicating the presence of LBRR frames. +For a stereo packet, these first flags correspond to the mid channel, and a + second set of flags is included for the side channel. + + +Because these are the first symbols decoded by the range coder and because they + are coded as binary values with uniform probability, they can be extracted + directly from the most significant bits of the first byte of compressed data. +Thus, a receiver can determine if an Opus frame contains any active SILK frames + without the overhead of using the range decoder. + +
    + +
    + +For Opus frames longer than 20 ms, a set of LBRR flags is + decoded for each channel that has its LBRR flag set. +Each set contains one flag per 20 ms SILK frame. +40 ms Opus frames use the 2-frame LBRR flag PDF from + , and 60 ms Opus frames use the + 3-frame LBRR flag PDF. +For each channel, the resulting 2- or 3-bit integer contains the corresponding + LBRR flag for each frame, packed in order from the LSB to the MSB. + + + +Frame Size +PDF +40 ms {0, 53, 53, 150}/256 +60 ms {0, 41, 20, 29, 41, 15, 28, 82}/256 + + + +A 10 or 20 ms Opus frame does not contain any per-frame LBRR flags, + as there may be at most one LBRR frame per channel. +The global LBRR flag in the header bits (see ) + is already sufficient to indicate the presence of that single LBRR frame. + + +

    + +The LBRR frames, if present, contain an encoded representation of the signal + immediately prior to the current Opus frame as if it were encoded with the + current mode, frame size, audio bandwidth, and channel count, even if those + differ from the prior Opus frame. +When one of these parameters changes from one Opus frame to the next, this + implies that the LBRR frames of the current Opus frame may not be simple + drop-in replacements for the contents of the previous Opus frame. + + + +For example, when switching from 20 ms to 60 ms, the 60 ms Opus + frame may contain LBRR frames covering up to three prior 20 ms Opus + frames, even if those frames already contained LBRR frames covering some of + the same time periods. +When switching from 20 ms to 10 ms, the 10 ms Opus frame can + contain an LBRR frame covering at most half the prior 20 ms Opus frame, + potentially leaving a hole that needs to be concealed from even a single + packet loss (see ). +When switching from mono to stereo, the LBRR frames in the first stereo Opus + frame MAY contain a non-trivial side channel. + + + +In order to properly produce LBRR frames under all conditions, an encoder might + need to buffer up to 60 ms of audio and re-encode it during these + transitions. +However, the reference implementation opts to disable LBRR frames at the + transition point for simplicity. +Since transitions are relatively infrequent in normal usage, this does not have + a significant impact on packet loss robustness. + + + +The LBRR frames immediately follow the LBRR flags, prior to any regular SILK + frames. + describes their exact contents. +LBRR frames do not include their own separate VAD flags. +LBRR frames are only meant to be transmitted for active speech, thus all LBRR + frames are treated as active. + + + +In a stereo Opus frame longer than 20 ms, although the per-frame LBRR + flags for the mid channel are coded as a unit before the per-frame LBRR flags + for the side channel, the LBRR frames themselves are interleaved. +The decoder parses an LBRR frame for the mid channel of a given 20 ms + interval (if present) and then immediately parses the corresponding LBRR + frame for the side channel (if present), before proceeding to the next + 20 ms interval. + +
    + +
    + +The regular SILK frame(s) follow the LBRR frames (if any). + describes their contents, as well. +Unlike the LBRR frames, a regular SILK frame is coded for each time interval in + an Opus frame, even if the corresponding VAD flags are unset. +For stereo Opus frames longer than 20 ms, the regular mid and side SILK + frames for each 20 ms interval are interleaved, just as with the LBRR + frames. +The side frame may be skipped by coding an appropriate flag, as detailed in + . + +

    + +Each SILK frame includes a set of side information that encodes + +The frame type and quantization type (), +Quantization gains (), +Short-term prediction filter coefficients (), +A Line Spectral Frequencies (LSF) interpolation weight (), + +Long-term prediction filter lags and gains (), + and + +A linear congruential generator (LCG) seed (). + +The quantized excitation signal (see ) follows + these at the end of the frame. + details the overall organization of a + SILK frame. + + + +Symbol(s) +PDF(s) +Condition + +Stereo Prediction Weights + + + +Mid-only Flag + + + +Frame Type + + + +Subframe Gains + + + +Normalized LSF Stage-1 Index + + + +Normalized LSF Stage-2 Residual + + + +Normalized LSF Interpolation Weight + +20 ms frame + +Primary Pitch Lag + +Voiced frame + +Subframe Pitch Contour + +Voiced frame + +Periodicity Index + +Voiced frame + +LTP Filter + +Voiced frame + +LTP Scaling + + + +LCG Seed + + + +Excitation Rate Level + + + +Excitation Pulse Counts + + + +Excitation Pulse Locations + +Non-zero pulse count + +Excitation LSBs + + + +Excitation Signs + + + + + +
    + +A SILK frame corresponding to the mid channel of a stereo Opus frame begins + with a pair of side channel prediction weights, designed such that zeros + indicate normal mid-side coupling. +Since these weights can change on every frame, the first portion of each frame + linearly interpolates between the previous weights and the current ones, using + zeros for the previous weights if none are available. +These prediction weights are never included in a mono Opus frame, and the + previous weights are reset to zeros on any transition from mono to stereo. +They are also not included in an LBRR frame for the side channel, even if the + LBRR flags indicate the corresponding mid channel was not coded. +In that case, the previous weights are used, again substituting in zeros if no + previous weights are available since the last decoder reset + (see ). + + + +To summarize, these weights are coded if and only if + +This is a stereo Opus frame (), and +The current SILK frame corresponds to the mid channel. + + + + +The prediction weights are coded in three separate pieces, which are decoded + by silk_stereo_decode_pred() (decode_stereo_pred.c). +The first piece jointly codes the high-order part of a table index for both + weights. +The second piece codes the low-order part of each table index. +The third piece codes an offset used to linearly interpolate between table + indices. +The details are as follows. + + + +Let n be an index decoded with the 25-element stage-1 PDF in + . +Then let i0 and i1 be indices decoded with the stage-2 and stage-3 PDFs in + , respectively, and let i2 and i3 + be two more indices decoded with the stage-2 and stage-3 PDFs, all in that + order. + + + +Stage +PDF +Stage 1 +{7, 2, 1, 1, 1, + 10, 24, 8, 1, 1, + 3, 23, 92, 23, 3, + 1, 1, 8, 24, 10, + 1, 1, 1, 2, 7}/256 + +Stage 2 +{85, 86, 85}/256 + +Stage 3 +{51, 51, 52, 51, 51}/256 + + + +Then use n, i0, and i2 to form two table indices, wi0 and wi1, according to +

    + +A separate quantization gain is coded for each 5 ms subframe. +These gains control the step size between quantization levels of the excitation + signal and, therefore, the quality of the reconstruction. +They are independent of and unrelated to the pitch contours coded for voiced + frames. +The quantization gains are themselves uniformly quantized to 6 bits on a + log scale, giving them a resolution of approximately 1.369 dB and a range + of approximately 1.94 dB to 88.21 dB. + + +The subframe gains are either coded independently, or relative to the gain from + the most recent coded subframe in the same channel. +Independent coding is used if and only if + + +This is the first subframe in the current SILK frame, and + +Either + + +This is the first SILK frame of its type (LBRR or regular) for this channel in + the current Opus frame, or + + +The previous SILK frame of the same type (LBRR or regular) for this channel in + the same Opus frame was not coded. + + + + + + + +In an independently coded subframe gain, the 3 most significant bits of the + quantization gain are decoded using a PDF selected from + based on the decoded signal + type (see ). + + + +Signal Type +PDF +Inactive {32, 112, 68, 29, 12, 1, 1, 1}/256 +Unvoiced {2, 17, 45, 60, 62, 47, 19, 4}/256 +Voiced {1, 3, 26, 71, 94, 50, 9, 2}/256 + + + +The 3 least significant bits are decoded using a uniform PDF: + + +PDF +{32, 32, 32, 32, 32, 32, 32, 32}/256 + + + +These 6 bits are combined to form a value, gain_index, between 0 and 63. +When the gain for the previous subframe is available, then the current gain is + limited as follows: +

    + +
    + where the division is integer division. +However, nothing in either the reconstruction process or the + quantization process in the encoder thus far guarantees that the coefficients + are monotonically increasing and separated well enough to ensure a stable + filter . +When using the reference encoder, roughly 2% of frames violate this constraint. +The next section describes a stabilization procedure used to make these + guarantees. +     + +
    + +
    + +The normalized LSF stabilization procedure is implemented in + silk_NLSF_stabilize() (NLSF_stabilize.c). +This process ensures that consecutive values of the normalized LSF + coefficients, NLSF_Q15[], are spaced some minimum distance apart + (predetermined to be the 0.01 percentile of a large training set). + gives the minimum spacings for NB and MB + and those for WB, where row k is the minimum allowed value of + NLSF_Q[k]-NLSF_Q[k-1]. +For the purposes of computing this spacing for the first and last coefficient, + NLSF_Q15[-1] is taken to be 0, and NLSF_Q15[d_LPC] is taken to be 32768. + + + +Coefficient +NB and MB +WB + 0 250 100 + 1 3 3 + 2 6 40 + 3 3 3 + 4 3 3 + 5 3 3 + 6 4 5 + 7 3 14 + 8 3 14 + 9 3 10 +10 461 11 +11 3 +12 8 +13 9 +14 7 +15 3 +16 347 + + + +The procedure starts off by trying to make small adjustments which attempt to + minimize the amount of distortion introduced. +After 20 such adjustments, it falls back to a more direct method which + guarantees the constraints are enforced but may require large adjustments. + + +Let NDeltaMin_Q15[k] be the minimum required spacing for the current audio + bandwidth from . +First, the procedure finds the index i where + NLSF_Q15[i] - NLSF_Q15[i-1] - NDeltaMin_Q15[i] is the + smallest, breaking ties by using the lower value of i. +If this value is non-negative, then the stabilization stops; the coefficients + satisfy all the constraints. +Otherwise, if i == 0, it sets NLSF_Q15[0] to NDeltaMin_Q15[0], and if + i == d_LPC, it sets NLSF_Q15[d_LPC-1] to + (32768 - NDeltaMin_Q15[d_LPC]). +For all other values of i, both NLSF_Q15[i-1] and NLSF_Q15[i] are updated as + follows: +
    +>1) + \ NDeltaMin_Q15[k] + /_ + k=0 + d_LPC + __ + max_center_Q15 = 32768 - (NDeltaMin_Q15[i]>>1) - \ NDeltaMin_Q15[k] + /_ + k=i+1 +center_freq_Q15 = clamp(min_center_Q15[i], + (NLSF_Q15[i-1] + NLSF_Q15[i] + 1)>>1, + max_center_Q15[i]) + + NLSF_Q15[i-1] = center_freq_Q15 - (NDeltaMin_Q15[i]>>1) + + NLSF_Q15[i] = NLSF_Q15[i-1] + NDeltaMin_Q15[i] . +]]> +
    +Then the procedure repeats again, until it has either executed 20 times or + has stopped because the coefficients satisfy all the constraints. +     + +After the 20th repetition of the above procedure, the following fallback + procedure executes once. +First, the values of NLSF_Q15[k] for 0 <= k < d_LPC + are sorted in ascending order. +Then for each value of k from 0 to d_LPC-1, NLSF_Q15[k] is set to +
    + +
    +Next, for each value of k from d_LPC-1 down to 0, NLSF_Q15[k] is set to +
    + +
    +     + +
    + +
    + +For 20 ms SILK frames, the first half of the frame (i.e., the first two + subframes) may use normalized LSF coefficients that are interpolated between + the decoded LSFs for the most recent coded frame (in the same channel) and the + current frame. +A Q2 interpolation factor follows the LSF coefficient indices in the bitstream, + which is decoded using the PDF in . +This happens in silk_decode_indices() (decode_indices.c). +After either + +An uncoded regular SILK frame in the side channel, or +A decoder reset (see ), + + the decoder still decodes this factor, but ignores its value and always uses + 4 instead. +For 10 ms SILK frames, this factor is not stored at all. + + + +PDF +{13, 22, 29, 11, 181}/256 + + + +Let n2_Q15[k] be the normalized LSF coefficients decoded by the procedure in + , n0_Q15[k] be the LSF coefficients + decoded for the prior frame, and w_Q2 be the interpolation factor. +Then the normalized LSF coefficients used for the first half of a 20 ms + frame, n1_Q15[k], are +
    +> 2) . +]]> +
    +This interpolation is performed in silk_decode_parameters() + (decode_parameters.c). +     +
    + +
    + +Any LPC filter A(z) can be split into a symmetric part P(z) and an + anti-symmetric part Q(z) such that +
    + +
    +with +
    + +
    +The even normalized LSF coefficients correspond to a pair of conjugate roots of + P(z), while the odd coefficients correspond to a pair of conjugate roots of + Q(z), all of which lie on the unit circle. +In addition, P(z) has a root at pi and Q(z) has a root at 0. +Thus, they may be reconstructed mathematically from a set of normalized LSF + coefficients, n[k], as +

    +The first multiply may require up to 48 bits of precision in the result to + avoid overflow. +The second multiply must be unsigned to avoid overflow with only 32 bits of + precision. +The reference implementation uses a slightly more complex formulation that + avoids the 32-bit overflow using signed multiplication, but is otherwise + equivalent. +     + +After 10 rounds of bandwidth expansion are performed, they are simply saturated + to 16 bits: +

    +Because this performs the actual saturation in the Q12 domain, but converts the + coefficients back to the Q17 domain for the purposes of prediction gain + limiting, this step must be performed after the 10th round of bandwidth + expansion, regardless of whether or not the Q12 version of any coefficient + still overflows a 16-bit integer. +This saturation is not performed if maxabs_Q12 drops to 32767 or less prior to + the 10th round. +     +

    + +The prediction gain of an LPC synthesis filter is the square-root of the output + energy when the filter is excited by a unit-energy impulse. +Even if the Q12 coefficients would fit, the resulting filter may still have a + significant gain (especially for voiced sounds), making the filter unstable. +silk_NLSF2A() applies up to 18 additional rounds of bandwidth expansion to + limit the prediction gain. +Instead of controlling the amount of bandwidth expansion using the prediction + gain itself (which may diverge to infinity for an unstable filter), + silk_NLSF2A() uses silk_LPC_inverse_pred_gain_QA() (LPC_inv_pred_gain.c) to + compute the reflection coefficients associated with the filter. +The filter is stable if and only if the magnitude of these coefficients is + sufficiently less than one. +The reflection coefficients, rc[k], can be computed using a simple Levinson + recurrence, initialized with the LPC coefficients + a[d_LPC-1][n] = a[n], and then updated via +
    + +
    +     + +However, silk_LPC_inverse_pred_gain_QA() approximates this using fixed-point + arithmetic to guarantee reproducible results across platforms and + implementations. +Since small changes in the coefficients can make a stable filter unstable, it + takes the real Q12 coefficients that will be used during reconstruction as + input. +Thus, let +

    + +As described in , SILK uses a + linear congruential generator (LCG) to inject pseudorandom noise into the + quantized excitation. +To ensure synchronization of this process between the encoder and decoder, each + SILK frame stores a 2-bit seed after the LTP parameters (if any). +The encoder may consider the choice of seed during quantization, and the + flexibility of this choice lets it reduce distortion, helping to pay for the + bit cost required to signal it. +The decoder reads the seed using the uniform 4-entry PDF in + , yielding a value between 0 and 3, inclusive. + + + +PDF +{64, 64, 64, 64}/256 + + +

    + +SILK codes the excitation using a modified version of the Pyramid Vector + Quantization (PVQ) codebook . +The PVQ codebook is designed for Laplace-distributed values and consists of all + sums of K signed, unit pulses in a vector of dimension N, where two pulses at + the same position are required to have the same sign. +Thus the codebook includes all integer codevectors y of dimension N that + satisfy +
    + +
    +Unlike regular PVQ, SILK uses a variable-length, rather than fixed-length, + encoding. +This encoding is better suited to the more Gaussian-like distribution of the + coefficient magnitudes and the non-uniform distribution of their signs (caused + by the quantization offset described below). +SILK also handles large codebooks by coding the least significant bits (LSBs) + of each coefficient directly. +This adds a small coding efficiency loss, but greatly reduces the computation + time and ROM size required for decoding, as implemented in + silk_decode_pulses() (decode_pulses.c). +     + + +SILK fixes the dimension of the codebook to N = 16. +The excitation is made up of a number of "shell blocks", each 16 samples in + size. + lists the number of shell blocks + required for a SILK frame for each possible audio bandwidth and frame size. +10 ms MB frames nominally contain 120 samples (10 ms at + 12 kHz), which is not a multiple of 16. +This is handled by coding 8 shell blocks (128 samples) and discarding the final + 8 samples of the last block. +The decoder contains no special case that prevents an encoder from placing + pulses in these samples, and they must be correctly parsed from the bitstream + if present, but they are otherwise ignored. + + + +Audio Bandwidth +Frame Size +Number of Shell Blocks +NB 10 ms 5 +MB 10 ms 8 +WB 10 ms 10 +NB 20 ms 10 +MB 20 ms 15 +WB 20 ms 20 + + +
    + +The first symbol in the excitation is a "rate level", which is an index from 0 + to 8, inclusive, coded using the PDF in + corresponding to the signal type of the current frame (from + ). +The rate level selects the PDF used to decode the number of pulses in + the individual shell blocks. +It does not directly convey any information about the bitrate or the number of + pulses itself, but merely changes the probability of the symbols in + . +Level 0 provides a more efficient encoding at low rates generally, and + level 8 provides a more efficient encoding at high rates generally, + though the most efficient level for a particular SILK frame may depend on the + exact distribution of the coded symbols. +An encoder should, but is not required to, use the most efficient rate level. + + + +Signal Type +PDF +Inactive or Unvoiced +{15, 51, 12, 46, 45, 13, 33, 27, 14}/256 +Voiced +{33, 30, 36, 17, 34, 49, 18, 21, 18}/256 + + +

    + +The total number of pulses in each of the shell blocks follows the rate level. +The pulse counts for all of the shell blocks are coded consecutively, before + the content of any of the blocks. +Each block may have anywhere from 0 to 16 pulses, inclusive, coded using the + 18-entry PDF in corresponding to the + rate level from . +The special value 17 indicates that this block has one or more additional + LSBs to decode for each coefficient. +If the decoder encounters this value, it decodes another value for the actual + pulse count of the block, but uses the PDF corresponding to the special rate + level 9 instead of the normal rate level. +This process repeats until the decoder reads a value less than 17, and it then + sets the number of extra LSBs used to the number of 17's decoded for that + block. +If it reads the value 17 ten times, then the next iteration uses the special + rate level 10 instead of 9. +The probability of decoding a 17 when using the PDF for rate level 10 is + zero, ensuring that the number of LSBs for a block will not exceed 10. +The cumulative distribution for rate level 10 is just a shifted version of + that for 9 and thus does not require any additional storage. + + + +Rate Level +PDF +0 +{131, 74, 25, 8, 3, 3, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1}/256 +1 +{58, 93, 60, 23, 7, 3, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1}/256 +2 +{43, 51, 46, 33, 24, 16, 11, 8, 6, 3, 3, 3, 2, 1, 1, 2, 1, 2}/256 +3 +{17, 52, 71, 57, 31, 12, 5, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1}/256 +4 +{6, 21, 41, 53, 49, 35, 21, 11, 6, 3, 2, 2, 1, 1, 1, 1, 1, 1}/256 +5 +{7, 14, 22, 28, 29, 28, 25, 20, 17, 13, 11, 9, 7, 5, 4, 4, 3, 10}/256 +6 +{2, 5, 14, 29, 42, 46, 41, 31, 19, 11, 6, 3, 2, 1, 1, 1, 1, 1}/256 +7 +{1, 2, 4, 10, 19, 29, 35, 37, 34, 28, 20, 14, 8, 5, 4, 2, 2, 2}/256 +8 +{1, 2, 2, 5, 9, 14, 20, 24, 27, 28, 26, 23, 20, 15, 11, 8, 6, 15}/256 +9 +{1, 1, 1, 6, 27, 58, 56, 39, 25, 14, 10, 6, 3, 3, 2, 1, 1, 2}/256 +10 +{2, 1, 6, 27, 58, 56, 39, 25, 14, 10, 6, 3, 3, 2, 1, 1, 2, 0}/256 + + +

    + + +After the signs have been read, there is enough information to reconstruct the + complete excitation signal. +This requires adding a constant quantization offset to each non-zero sample, + and then pseudorandomly inverting and offsetting every sample. +The constant quantization offset varies depending on the signal type and + quantization offset type (see ). + + + +Signal Type +Quantization Offset Type +Quantization Offset (Q23) +Inactive Low 25 +Inactive High 60 +Unvoiced Low 25 +Unvoiced High 60 +Voiced Low 8 +Voiced High 25 + + + +Let e_raw[i] be the raw excitation value at position i, with a magnitude + composed of the pulses at that location (see + ) combined with any additional LSBs (see + ), and with the corresponding sign decoded in + . +Additionally, let seed be the current pseudorandom seed, which is initialized + to the value decoded from for the first sample in + the current SILK frame, and updated for each subsequent sample according to + the procedure below. +Finally, let offset_Q23 be the quantization offset from + . +Then the following procedure produces the final reconstructed excitation value, + e_Q23[i]: +

    +When e_raw[i] is zero, sign() returns 0 by the definition in + , so the factor of 20 does not get added. +The final e_Q23[i] value may require more than 16 bits per sample, but will not + require more than 23, including the sign. +     + +
    + +
    + +
    + + +The remainder of the reconstruction process for the frame does not need to be + bit-exact, as small errors should only introduce proportionally small + distortions. +Although the reference implementation only includes a fixed-point version of + the remaining steps, this section describes them in terms of a floating-point + version for simplicity. +This produces a signal with a nominal range of -1.0 to 1.0. + + + +silk_decode_core() (decode_core.c) contains the code for the main + reconstruction process. +It proceeds subframe-by-subframe, since quantization gains, LTP parameters, and + (in 20 ms SILK frames) LPC coefficients can vary from one to the + next. + + + +Let a_Q12[k] be the LPC coefficients for the current subframe. +If this is the first or second subframe of a 20 ms SILK frame and the LSF + interpolation factor, w_Q2 (see ), is + less than 4, then these correspond to the final LPC coefficients produced by + from the interpolated LSF coefficients, + n1_Q15[k] (computed in ). +Otherwise, they correspond to the final LPC coefficients produced from the + uninterpolated LSF coefficients for the current frame, n2_Q15[k]. + + + +Also, let n be the number of samples in a subframe (40 for NB, 60 for MB, and + 80 for WB), s be the index of the current subframe in this SILK frame (0 or 1 + for 10 ms frames, or 0 to 3 for 20 ms frames), and j be the index of + the first sample in the residual corresponding to the current subframe. + + +
    + +Voiced SILK frames (see ) pass the excitation + through an LTP filter using the parameters decoded in + to produce an LPC residual. +The LTP filter requires LPC residual values from before the current subframe as + input. +However, since the LPC coefficients may have changed, it obtains this residual + by "rewhitening" the corresponding output signal using the LPC coefficients + from the current subframe. +Let out[i] for + (j - pitch_lags[s] - d_LPC - 2) <= i < j + be the fully reconstructed output signal from the last + (pitch_lags[s] + d_LPC + 2) samples of previous subframes + (see ), where pitch_lags[s] is the pitch + lag for the current subframe from . +During reconstruction of the first subframe for this channel after either + +An uncoded regular SILK frame (if this is the side channel), or +A decoder reset (see ), + + out[] is rewhitened into an LPC residual, + res[i], via +
    + +
    +This requires storage to buffer up to 306 values of out[i] from previous + subframes. +This corresponds to WB with a maximum pitch lag of + 18 ms * 16 kHz samples, plus 16 samples for d_LPC, plus 2 + samples for the width of the LTP filter. +     + + +Let e_Q23[i] for j <= i < (j + n) be the + excitation for the current subframe, and b_Q7[k] for + 0 <= k < 5 be the coefficients of the LTP filter + taken from the codebook entry in one of + Tables  + through  + corresponding to the index decoded for the current subframe in + . +Then for i such that j <= i < (j + n), + the LPC residual is +
    + +
    +     + + +For unvoiced frames, the LPC residual for + j <= i < (j + n) is simply a normalized + copy of the excitation signal, i.e., +
    + +
    +     +
    + +
    + +LPC synthesis uses the short-term LPC filter to predict the next output + coefficient. +For i such that (j - d_LPC) <= i < j, let + lpc[i] be the result of LPC synthesis from the last d_LPC samples of the + previous subframe, or zeros in the first subframe for this channel after + either + +An uncoded regular SILK frame (if this is the side channel), or +A decoder reset (see ). + +Then for i such that j <= i < (j + n), the + result of LPC synthesis for the current subframe is +
    + +
    +The decoder saves the final d_LPC values, i.e., lpc[i] such that + (j + n - d_LPC) <= i < (j + n), + to feed into the LPC synthesis of the next subframe. +This requires storage for up to 16 values of lpc[i] (for WB frames). +     + + +Then, the signal is clamped into the final nominal range: +
    + +
    +This clamping occurs entirely after the LPC synthesis filter has run. +The decoder saves the unclamped values, lpc[i], to feed into the LPC filter for + the next subframe, but saves the clamped values, out[i], for rewhitening in + voiced frames. +     +
    + +
    + +
    + +
    + +For stereo streams, after decoding a frame from each channel, the decoder must + convert the mid-side (MS) representation into a left-right (LR) + representation. +The function silk_stereo_MS_to_LR (stereo_MS_to_LR.c) implements this process. +In it, the decoder predicts the side channel using a) a simple low-passed + version of the mid channel, and b) the unfiltered mid channel, using the + prediction weights decoded in . +This simple low-pass filter imposes a one-sample delay, and the unfiltered +mid channel is also delayed by one sample. +In order to allow seamless switching between stereo and mono, mono streams must + also impose the same one-sample delay. +The encoder requires an additional one-sample delay for both mono and stereo + streams, though an encoder may omit the delay for mono if it knows it will + never switch to stereo. + + + +The unmixing process operates in two phases. +The first phase lasts for 8 ms, during which it interpolates the + prediction weights from the previous frame, prev_w0_Q13 and prev_w1_Q13, to + the values for the current frame, w0_Q13 and w1_Q13. +The second phase simply uses these weights for the remainder of the frame. + + + +Let mid[i] and side[i] be the contents of out[i] (from + ) for the current mid and side channels, + respectively, and let left[i] and right[i] be the corresponding stereo output + channels. +If the side channel is not coded (see ), + then side[i] is set to zero. +Also let j be defined as in , n1 be + the number of samples in phase 1 (64 for NB, 96 for MB, and 128 for WB), + and n2 be the total number of samples in the frame. +Then for i such that j <= i < (j + n2), + the left and right channel output is +
    + +
    +These formulas require two samples prior to index j, the start of the + frame, for the mid channel, and one prior sample for the side channel. +For the first frame after a decoder reset, zeros are used instead. +     + +
    + +
    + +After stereo unmixing (if any), the decoder applies resampling to convert the + decoded SILK output to the sample rate desired by the application. +This is necessary when decoding a Hybrid frame at SWB or FB sample rates, or + whenever the decoder wants the output at a different sample rate than the + internal SILK sampling rate (e.g., to allow a constant sample rate when the + audio bandwidth changes, or to allow mixing with audio from other + applications). +The resampler itself is non-normative, and a decoder can use any method it + wants to perform the resampling. + + + +However, a minimum amount of delay is imposed to allow the resampler to + operate, and this delay is normative, so that the corresponding delay can be + applied to the MDCT layer in the encoder. +A decoder is always free to use a resampler which requires more delay than + allowed for here (e.g., to improve quality), but it must then delay the output + of the MDCT layer by this extra amount. +Keeping as much delay as possible on the encoder side allows an encoder which + knows it will never use any of the SILK or Hybrid modes to skip this delay. +By contrast, if it were all applied by the decoder, then a decoder which + processes audio in fixed-size blocks would be forced to delay the output of + CELT frames just in case of a later switch to a SILK or Hybrid mode. + + + + gives the maximum resampler delay + in samples at 48 kHz for each SILK audio bandwidth. +Because the actual output rate may not be 48 kHz, it may not be possible + to achieve exactly these delays while using a whole number of input or output + samples. +The reference implementation is able to resample to any of the supported + output sampling rates (8, 12, 16, 24, or 48 kHz) within or near this + delay constraint. +Some resampling filters (including those used by the reference implementation) + may add a delay that is not an exact integer, or is not linear-phase, and so + cannot be represented by a single delay at all frequencies. +However, such deviations are unlikely to be perceptible, and the comparison + tool described in is designed to be relatively + insensitive to them. +The delays listed here are the ones that should be targeted by the encoder. + + + +Audio Bandwidth +Delay in millisecond +NB 0.538 +MB 0.692 +WB 0.706 + + + +NB is given a smaller decoder delay allocation than MB and WB to allow a + higher-order filter when resampling to 8 kHz in both the encoder and + decoder. +This implies that the audio content of two SILK frames operating at different + bandwidths are not perfectly aligned in time. +This is not an issue for any transitions described in + , because they all involve a SILK decoder reset. +When the decoder is reset, any samples remaining in the resampling buffer + are discarded, and the resampler is re-initialized with silence. + + +
    + +

    + + +The CELT layer of Opus is based on the Modified Discrete Cosine Transform + with partially overlapping windows of 5 to 22.5 ms. +The main principle behind CELT is that the MDCT spectrum is divided into +bands that (roughly) follow the Bark scale, i.e., the scale of the ear's +critical bands . The normal CELT layer uses 21 of those bands, though Opus + Custom (see ) may use a different number of bands. +In Hybrid mode, the first 17 bands (up to 8 kHz) are not coded. +A band can contain as little as one MDCT bin per channel, and as many as 176 +bins per channel, as detailed in . +In each band, the gain (energy) is coded separately from +the shape of the spectrum. Coding the gain explicitly makes it easy to +preserve the spectral envelope of the signal.

In some circumstances, it is +possible for a decoded value to be out of range due to a very small amount of redundancy +in the encoding of large integers by the range coder. +In that case, the decoder should assume there has been an error in the coding, +decoding, or transmission and SHOULD take measures to conceal the error and/or report +to the application that a problem has occurred. Such out of range errors cannot occur +in the SILK layer. + + +
    + +The "transient" flag indicates whether the frame uses a single long MDCT or several short MDCTs. +When it is set, then the MDCT coefficients represent multiple +short MDCTs in the frame. When not set, the coefficients represent a single +long MDCT for the frame. The flag is encoded in the bitstream with a probability of 1/8. +In addition to the global transient flag is a per-band +binary flag to change the time-frequency (tf) resolution independently in each band. The +change in tf resolution is defined in tf_select_table[][] in celt.c and depends +on the frame size, whether the transient flag is set, and the value of tf_select. +The tf_select flag uses a 1/2 probability, but is only decoded +if it can have an impact on the result knowing the value of all per-band +tf_change flags. + +
    + +
    + + +It is important to quantize the energy with sufficient resolution because +any energy quantization error cannot be compensated for at a later +stage. Regardless of the resolution used for encoding the spectral shape of a band, +it is perceptually important to preserve the energy in each band. CELT uses a +three-step coarse-fine-fine strategy for encoding the energy in the base-2 log +domain, as implemented in quant_bands.c + +
    + +Coarse quantization of the energy uses a fixed resolution of 6 dB +(integer part of base-2 log). To minimize the bitrate, prediction is applied +both in time (using the previous frame) and in frequency (using the previous +bands). The part of the prediction that is based on the +previous frame can be disabled, creating an "intra" frame where the energy +is coded without reference to prior frames. The decoder first reads the intra flag +to determine what prediction is used. +The 2-D z-transform of +the prediction filter is: +
    + +
    +where b is the band index and l is the frame index. The prediction coefficients +applied depend on the frame size in use when not using intra energy and are alpha=0, beta=4915/32768 +when using intra energy. +The time-domain prediction is based on the final fine quantization of the previous +frame, while the frequency domain (within the current frame) prediction is based +on coarse quantization only (because the fine quantization has not been computed +yet). The prediction is clamped internally so that fixed point implementations with +limited dynamic range always remain in the same state as floating point implementations. +We approximate the ideal +probability distribution of the prediction error using a Laplace distribution +with separate parameters for each frame size in intra- and inter-frame modes. These +parameters are held in the e_prob_model table in quant_bands.c. +The +coarse energy quantization is performed by unquant_coarse_energy() and +unquant_coarse_energy_impl() (quant_bands.c). The encoding of the Laplace-distributed values is +implemented in ec_laplace_decode() (laplace.c). +     + +
    + +
    + +The number of bits assigned to fine energy quantization in each band is determined +by the bit allocation computation described in . +Let B_i be the number of fine energy bits +for band i; the refinement is an integer f in the range [0,2**B_i-1]. The mapping between f +and the correction applied to the coarse energy is equal to (f+1/2)/2**B_i - 1/2. Fine +energy quantization is implemented in quant_fine_energy() (quant_bands.c). + + +When some bits are left "unused" after all other flags have been decoded, these bits +are assigned to a "final" step of fine allocation. In effect, these bits are used +to add one extra fine energy bit per band per channel. The allocation process +determines two "priorities" for the final fine bits. +Any remaining bits are first assigned only to bands of priority 0, starting +from band 0 and going up. If all bands of priority 0 have received one bit per +channel, then bands of priority 1 are assigned an extra bit per channel, +starting from band 0. If any bits are left after this, they are left unused. +This is implemented in unquant_energy_finalise() (quant_bands.c). + + +
    + +
    + +
    + +Because the bit allocation drives the decoding of the range-coder +stream, it MUST be recovered exactly so that identical coding decisions are +made in the encoder and decoder. Any deviation from the reference's resulting +bit allocation will result in corrupted output, though implementers are +free to implement the procedure in any way which produces identical results. + +The per-band gain-shape structure of the CELT layer ensures that using + the same number of bits for the spectral shape of a band in every frame will + result in a roughly constant signal-to-noise ratio in that band. +This results in coding noise that has the same spectral envelope as the signal. +The masking curve produced by a standard psychoacoustic model also closely + follows the spectral envelope of the signal. +This structure means that the ideal allocation is more consistent from frame to + frame than it is for other codecs without an equivalent structure, and that a + fixed allocation provides fairly consistent perceptual + performance . + +Many codecs transmit significant amounts of side information to control the + bit allocation within a frame. +Often this control is only indirect, and must be exercised carefully to + achieve the desired rate constraints. +The CELT layer, however, can adapt over a very wide range of rates, and thus + has a large number of codebook sizes to choose from for each band. +Explicitly signaling the size of each of these codebooks would impose + considerable overhead, even though the allocation is relatively static from + frame to frame. +This is because all of the information required to compute these codebook sizes + must be derived from a single frame by itself, in order to retain robustness + to packet loss, so the signaling cannot take advantage of knowledge of the + allocation in neighboring frames. +This problem is exacerbated in low-latency (small frame size) applications, + which would include this overhead in every frame. + +For this reason, in the MDCT mode Opus uses a primarily implicit bit +allocation. The available bitstream capacity is known in advance to both +the encoder and decoder without additional signaling, ultimately from the +packet sizes expressed by a higher-level protocol. Using this information, +the codec interpolates an allocation from a hard-coded table. + +While the band-energy structure effectively models intra-band masking, +it ignores the weaker inter-band masking, band-temporal masking, and +other less significant perceptual effects. While these effects can +often be ignored, they can become significant for particular samples. One +mechanism available to encoders would be to simply increase the overall +rate for these frames, but this is not possible in a constant rate mode +and can be fairly inefficient. As a result three explicitly signaled +mechanisms are provided to alter the implicit allocation: + + + +Band boost +Allocation trim +Band skipping + + + +The first of these mechanisms, band boost, allows an encoder to boost +the allocation in specific bands. The second, allocation trim, works by +biasing the overall allocation towards higher or lower frequency bands. The third, band +skipping, selects which low-precision high frequency bands +will be allocated no shape bits at all. + +In stereo mode there are two additional parameters +potentially coded as part of the allocation procedure: a parameter to allow the +selective elimination of allocation for the 'side' (i.e., intensity stereo) in jointly coded bands, +and a flag to deactivate joint coding (i.e., dual stereo). These values are not signaled if +they would be meaningless in the overall context of the allocation. + +Because every signaled adjustment increases overhead and implementation +complexity, none were included speculatively: the reference encoder makes use +of all of these mechanisms. While the decision logic in the reference was +found to be effective enough to justify the overhead and complexity, further +analysis techniques may be discovered which increase the effectiveness of these +parameters. As with other signaled parameters, an encoder is free to choose the +values in any manner, but unless a technique is known to deliver superior +perceptual results the methods used by the reference implementation should be +used. + +The allocation process consists of the following steps: determining the per-band +maximum allocation vector, decoding the boosts, decoding the tilt, determining +the remaining capacity of the frame, searching the mode table for the +entry nearest but not exceeding the available space (subject to the tilt, boosts, band +maximums, and band minimums), linear interpolation, reallocation of +unused bits with concurrent skip decoding, determination of the +fine-energy vs. shape split, and final reallocation. This process results +in a per-band shape allocation (in 1/8th bit units), a per-band fine-energy +allocation (in 1 bit per channel units), a set of band priorities for +controlling the use of remaining bits at the end of the frame, and a +remaining balance of unallocated space, which is usually zero except +at very high rates. + + +The "static" bit allocation (in 1/8 bits) for a quality q, excluding the minimums, maximums, +tilt and boosts, is equal to channels*N*alloc[band][q]<<LM>>2, where +alloc[][] is given in and LM=log2(frame_size/120). The allocation +is obtained by linearly interpolating between two values of q (in steps of 1/64) to find the +highest allocation that does not exceed the number of bits remaining. + + + + Rows indicate the MDCT bands, columns are the different quality (q) parameters.

The value is +approximate because the shape encoding is variable rate (due +to entropy coding of splitting parameters). Setting the maximum too low reduces the +maximum achievable quality in a band while setting it too high +may result in waste: bitstream capacity available at the end +of the frame which can not be put to any use. The maximums +specified by the codec reflect the average maximum. In the reference +implementation, the maximums in bits/sample are precomputed in a static table +(see cache_caps50[] in static_modes_float.h) for each band, +for each value of LM, and for both mono and stereo. + +Implementations are expected +to simply use the same table data, but the procedure for generating +this table is included in rate.c as part of compute_pulse_cache(). + +To convert the values in cache.caps into the actual maximums: first +set nbBands to the maximum number of bands for this mode, and stereo to +zero if stereo is not in use and one otherwise. For each band set N +to the number of MDCT bins covered by the band (for one channel), set LM +to the shift value for the frame size, +then set i to nbBands*(2*LM+stereo). Then set the maximum for the band to +the i-th index of cache.caps + 64 and multiply by the number of channels +in the current frame (one or two) and by N, then divide the result by 4 +using integer division. The resulting vector will be called +cap[]. The elements fit in signed 16-bit integers but do not fit in 8 bits. +This procedure is implemented in the reference in the function init_caps() in celt.c. + + +The band boosts are represented by a series of binary symbols which +are entropy coded with very low probability. Each band can potentially be boosted +multiple times, subject to the frame actually having enough room to obey +the boost and having enough room to code the boost symbol. The default +coding cost for a boost starts out at six bits (probability p=1/64), but subsequent boosts +in a band cost only a single bit and every time a band is boosted the +initial cost is reduced (down to a minimum of two bits, or p=1/4). Since the initial +cost of coding a boost is 6 bits, the coding cost of the boost symbols when +completely unused is 0.48 bits/frame for a 21 band mode (21*-log2(1-1/2**6)). + +To decode the band boosts: First set 'dynalloc_logp' to 6, the initial +amount of storage required to signal a boost in bits, 'total_bits' to the +size of the frame in 8th bits, 'total_boost' to zero, and 'tell' to the total number +of 8th bits decoded +so far. For each band from the coding start (0 normally, but 17 in Hybrid mode) +to the coding end (which changes depending on the signaled bandwidth), the boost quanta +in units of 1/8 bit is calculated as quanta = min(8*N, max(48, N)). +This represents a boost step size of six bits, subject to a lower limit of +1/8th bit/sample and an upper limit of 1 bit/sample. +Set 'boost' to zero and 'dynalloc_loop_logp' +to dynalloc_logp. While dynalloc_loop_log (the current worst case symbol cost) in +8th bits plus tell is less than total_bits plus total_boost and boost is less than cap[] for this +band: Decode a bit from the bitstream with a with dynalloc_loop_logp as the cost +of a one, update tell to reflect the current used capacity, if the decoded value +is zero break the loop otherwise add quanta to boost and total_boost, subtract quanta from +total_bits, and set dynalloc_loop_log to 1. When the while loop finishes +boost contains the boost for this band. If boost is non-zero and dynalloc_logp +is greater than 2, decrease dynalloc_logp. Once this process has been +executed on all bands, the band boosts have been decoded. This procedure +is implemented around line 2474 of celt.c. + +At very low rates it is possible that there won't be enough available +space to execute the inner loop even once. In these cases band boost +is not possible but its overhead is completely eliminated. Because of the +high cost of band boost when activated, a reasonable encoder should not be +using it at very low rates. The reference implements its dynalloc decision +logic around line 1304 of celt.c. + +The allocation trim is a integer value from 0-10. The default value of +5 indicates no trim. The trim parameter is entropy coded in order to +lower the coding cost of less extreme adjustments. Values lower than +5 bias the allocation towards lower frequencies and values above 5 +bias it towards higher frequencies. Like other signaled parameters, signaling +of the trim is gated so that it is not included if there is insufficient space +available in the bitstream. To decode the trim, first set +the trim value to 5, then if and only if the count of decoded 8th bits so far (ec_tell_frac) +plus 48 (6 bits) is less than or equal to the total frame size in 8th +bits minus total_boost (a product of the above band boost procedure), +decode the trim value using the PDF in . + + +PDF +{1, 1, 2, 5, 10, 22, 46, 22, 10, 5, 2, 2}/128 + + +For 10 ms and 20 ms frames using short blocks and that have at least LM+2 bits left prior to +the allocation process, then one anti-collapse bit is reserved in the allocation process so it can +be decoded later. Following the the anti-collapse reservation, one bit is reserved for skip if available. + +For stereo frames, bits are reserved for intensity stereo and for dual stereo. Intensity stereo +requires ilog2(end-start) bits. Those bits are reserved if there is enough bits left. Following this, one +bit is reserved for dual stereo if available. + + +The allocation computation begins by setting up some initial conditions. +'total' is set to the remaining available 8th bits, computed by taking the +size of the coded frame times 8 and subtracting ec_tell_frac(). From this value, one (8th bit) +is subtracted to ensure that the resulting allocation will be conservative. 'anti_collapse_rsv' +is set to 8 (8th bits) if and only if the frame is a transient, LM is greater than 1, and total is +greater than or equal to (LM+2) * 8. Total is then decremented by anti_collapse_rsv and clamped +to be equal to or greater than zero. 'skip_rsv' is set to 8 (8th bits) if total is greater than +8, otherwise it is zero. Total is then decremented by skip_rsv. This reserves space for the +final skipping flag. + +If the current frame is stereo, intensity_rsv is set to the conservative log2 in 8th bits +of the number of coded bands for this frame (given by the table LOG2_FRAC_TABLE in rate.c). If +intensity_rsv is greater than total then intensity_rsv is set to zero. Otherwise total is +decremented by intensity_rsv, and if total is still greater than 8, dual_stereo_rsv is +set to 8 and total is decremented by dual_stereo_rsv. + +The allocation process then computes a vector representing the hard minimum amounts allocation +any band will receive for shape. This minimum is higher than the technical limit of the PVQ +process, but very low rate allocations produce an excessively sparse spectrum and these bands +are better served by having no allocation at all. For each coded band, set thresh[band] to +twenty-four times the number of MDCT bins in the band and divide by 16. If 8 times the number +of channels is greater, use that instead. This sets the minimum allocation to one bit per channel +or 48 128th bits per MDCT bin, whichever is greater. The band-size dependent part of this +value is not scaled by the channel count, because at the very low rates where this limit is +applicable there will usually be no bits allocated to the side. + +The previously decoded allocation trim is used to derive a vector of per-band adjustments, +'trim_offsets[]'. For each coded band take the alloc_trim and subtract 5 and LM. Then multiply +the result by the number of channels, the number of MDCT bins in the shortest frame size for this mode, +the number of remaining bands, 2**LM, and 8. Then divide this value by 64. Finally, if the +number of MDCT bins in the band per channel is only one, 8 times the number of channels is subtracted +in order to diminish the allocation by one bit, because width 1 bands receive greater benefit +from the coarse energy coding. + + +
    + +
    + +In each band, the normalized "shape" is encoded +using a vector quantization scheme called a "pyramid vector quantizer". + + +In +the simplest case, the number of bits allocated in + is converted to a number of pulses as described +by . Knowing the number of pulses and the +number of samples in the band, the decoder calculates the size of the codebook +as detailed in . The size is used to decode +an unsigned integer (uniform probability model), which is the codeword index. +This index is converted into the corresponding vector as explained in +. This vector is then scaled to unit norm. + + +
    + +Although the allocation is performed in 1/8th bit units, the quantization requires +an integer number of pulses K. To do this, the encoder searches for the value +of K that produces the number of bits nearest to the allocated value +(rounding down if exactly halfway between two values), not to exceed +the total number of bits available. For efficiency reasons, the search is performed against a +precomputed allocation table which only permits some K values for each N. The number of +codebook entries can be computed as explained in . The difference +between the number of bits allocated and the number of bits used is accumulated to a +"balance" (initialized to zero) that helps adjust the +allocation for the next bands. One third of the balance is applied to the +bit allocation of each band to help achieve the target allocation. The only +exceptions are the band before the last and the last band, for which half the balance +and the whole balance are applied, respectively. + +
    + +
    + + +Decoding of PVQ vectors is implemented in decode_pulses() (cwrs.c). +The unique codeword index is decoded as a uniformly-distributed integer value between 0 and +V(N,K)-1, where V(N,K) is the number of possible combinations of K pulses in +N samples. The index is then converted to a vector in the same way specified in +. The indexing is based on the calculation of V(N,K) +(denoted N(L,K) in ). + + + + The number of combinations can be computed recursively as +V(N,K) = V(N-1,K) + V(N,K-1) + V(N-1,K-1), with V(N,0) = 1 and V(0,K) = 0, K != 0. +There are many different ways to compute V(N,K), including precomputed tables and direct +use of the recursive formulation. The reference implementation applies the recursive +formulation one line (or column) at a time to save on memory use, +along with an alternate, +univariate recurrence to initialize an arbitrary line, and direct +polynomial solutions for small N. All of these methods are +equivalent, and have different trade-offs in speed, memory usage, and +code size. Implementations MAY use any methods they like, as long as +they are equivalent to the mathematical definition. + + + +The decoded vector X is recovered as follows. +Let i be the index decoded with the procedure in + with ft = V(N,K), so that 0 <= i < V(N,K). +Let k = K. +Then for j = 0 to (N - 1), inclusive, do: + +Let p = (V(N-j-1,k) + V(N-j,k))/2. + +If i < p, then let sgn = 1, else let sgn = -1 + and set i = i - p. + +Let k0 = k and set p = p - V(N-j-1,k). + +While p > i, set k = k - 1 and + p = p - V(N-j-1,k). + + +Set X[j] = sgn*(k0 - k) and i = i - p. + + + + + +The decoded vector X is then normalized such that its +L2-norm equals one. + +
    + +
    + +The normalized vector decoded in is then rotated +for the purpose of avoiding tonal artifacts. The rotation gain is equal to +
    + +
    + +where N is the number of dimensions, K is the number of pulses, and f_r depends on +the value of the "spread" parameter in the bit-stream. +     + + +Spread value +f_r + 0 infinite (no rotation) + 1 15 + 2 10 + 3 5 + + + +The rotation angle is then calculated as +
    + +
    +A 2-D rotation R(i,j) between points x_i and x_j is defined as: +
    + +
    + +An N-D rotation is then achieved by applying a series of 2-D rotations back and forth, in the +following order: R(x_1, x_2), R(x_2, x_3), ..., R(x_N-2, X_N-1), R(x_N-1, X_N), +R(x_N-2, X_N-1), ..., R(x_1, x_2). +     + + +If the decoded vector represents more +than one time block, then this spreading process is applied separately on each time block. +Also, if each block represents 8 samples or more, then another N-D rotation, by +(pi/2-theta), is applied before the rotation described above. This +extra rotation is applied in an interleaved manner with a stride equal to round(sqrt(N/nb_blocks)), +i.e., it is applied independently for each set of sample S_k = {stride*n + k}, n=0..N/stride-1. + +
    + +
    + +To avoid the need for multi-precision calculations when decoding PVQ codevectors, +the maximum size allowed for codebooks is 32 bits. When larger codebooks are +needed, the vector is instead split in two sub-vectors of size N/2. +A quantized gain parameter with precision +derived from the current allocation is entropy coded to represent the relative +gains of each side of the split, and the entire decoding process is recursively +applied. Multiple levels of splitting may be applied up to a limit of LM+1 splits. +The same recursive mechanism is applied for the joint coding +of stereo audio. + + +
    + +
    + +The time-frequency (TF) parameters are used to control the time-frequency resolution tradeoff +in each coded band. For each band, there are two possible TF choices. For the first +band coded, the PDF is {3, 1}/4 for frames marked as transient and {15, 1}/16 for +the other frames. For subsequent bands, the TF choice is coded relative to the +previous TF choice with probability {15, 1}/15 for transient frames and {31, 1}/32 +otherwise. The mapping between the decoded TF choices and the adjustment in TF +resolution is shown in the tables below. + + + +Frame size (ms) +0 +1 +2.5 0 -1 +5 0 -1 +10 0 -2 +20 0 -2 + + + +Frame size (ms) +0 +1 +2.5 0 -1 +5 0 -2 +10 0 -3 +20 0 -3 + + + + +Frame size (ms) +0 +1 +2.5 0 -1 +5 1 0 +10 2 0 +20 3 0 + + + +Frame size (ms) +0 +1 +2.5 0 -1 +5 1 -1 +10 1 -1 +20 1 -1 + + + +A negative TF adjustment means that the temporal resolution is increased, +while a positive TF adjustment means that the frequency resolution is increased. +Changes in TF resolution are implemented using the Hadamard transform . To increase +the time resolution by N, N "levels" of the Hadamard transform are applied to the +decoded vector for each interleaved MDCT vector. To increase the frequency resolution +(assumes a transient frame), then N levels of the Hadamard transform are applied +across the interleaved MDCT vector. In the case of increased +time resolution the decoder uses the "sequency order" because the input vector +is sorted in time. + +
    + + +
    + +
    + +The anti-collapse feature is designed to avoid the situation where the use of multiple +short MDCTs causes the energy in one or more of the MDCTs to be zero for +some bands, causing unpleasant artifacts. +When the frame has the transient bit set, an anti-collapse bit is decoded. +When anti-collapse is set, the energy in each small MDCT is prevented +from collapsing to zero. For each band of each MDCT where a collapse is +detected, a pseudo-random signal is inserted with an energy corresponding +to the minimum energy over the two previous frames. A renormalization step is +then required to ensure that the anti-collapse step did not alter the +energy preservation property. + +
    + +
    + +Just as each band was normalized in the encoder, the last step of the decoder before +the inverse MDCT is to denormalize the bands. Each decoded normalized band is +multiplied by the square root of the decoded energy. This is done by denormalise_bands() +(bands.c). + +
    + +
    + + +The inverse MDCT implementation has no special characteristics. The +input is N frequency-domain samples and the output is 2*N time-domain +samples, while scaling by 1/2. A "low-overlap" window reduces the algorithmic delay. +It is derived from a basic (full overlap) 240-sample version of the window used by the Vorbis codec: +
    + +
    +The low-overlap window is created by zero-padding the basic window and inserting ones in the +middle, such that the resulting window still satisfies power complementarity . +The IMDCT and +windowing are performed by mdct_backward (mdct.c). +     + +
    + +The output of the inverse MDCT (after weighted overlap-add) is sent to the +post-filter. Although the post-filter is applied at the end, the post-filter +parameters are encoded at the beginning, just after the silence flag. +The post-filter can be switched on or off using one bit (logp=1). +If the post-filter is enabled, then the octave is decoded as an integer value +between 0 and 6 of uniform probability. Once the octave is known, the fine pitch +within the octave is decoded using 4+octave raw bits. The final pitch period +is equal to (16<<octave)+fine_pitch-1 so it is bounded between 15 and 1022, +inclusively. Next, the gain is decoded as three raw bits and is equal to +G=3*(int_gain+1)/32. The set of post-filter taps is decoded last, using +a pdf equal to {2, 1, 1}/4. Tapset zero corresponds to the filter coefficients +g0 = 0.3066406250, g1 = 0.2170410156, g2 = 0.1296386719. Tapset one +corresponds to the filter coefficients g0 = 0.4638671875, g1 = 0.2680664062, +g2 = 0, and tapset two uses filter coefficients g0 = 0.7998046875, +g1 = 0.1000976562, g2 = 0. + + + +The post-filter response is thus computed as: +
    + + + +
    + +During a transition between different gains, a smooth transition is calculated +using the square of the MDCT window. It is important that values of y(n) be +interpolated one at a time such that the past value of y(n) used is interpolated. +     +
    + +
    + +After the post-filter, +the signal is de-emphasized using the inverse of the pre-emphasis filter +used in the encoder: +
    + +
    +where alpha_p=0.8500061035. +     +
    + +
    + +
    + +
    + +Packet loss concealment (PLC) is an optional decoder-side feature that +SHOULD be included when receiving from an unreliable channel. Because +PLC is not part of the bitstream, there are many acceptable ways to +implement PLC with different complexity/quality trade-offs. + + + +The PLC in +the reference implementation depends on the mode of last packet received. +In CELT mode, the PLC finds a periodicity in the decoded +signal and repeats the windowed waveform using the pitch offset. The windowed +waveform is overlapped in such a way as to preserve the time-domain aliasing +cancellation with the previous frame and the next frame. This is implemented +in celt_decode_lost() (mdct.c). In SILK mode, the PLC uses LPC extrapolation +from the previous frame, implemented in silk_PLC() (PLC.c). + + +
    + +Clock drift refers to the gradual desynchronization of two endpoints +whose sample clocks run at different frequencies while they are streaming +live audio. Differences in clock frequencies are generally attributable to +manufacturing variation in the endpoints' clock hardware. For long-lived +streams, the time difference between sender and receiver can grow without +bound. + + + +When the sender's clock runs slower than the receiver's, the effect is similar +to packet loss: too few packets are received. The receiver can distinguish +between drift and loss if the transport provides packet timestamps. A receiver +for live streams SHOULD conceal the effects of drift, and MAY do so by invoking +the PLC. + + + +When the sender's clock runs faster than the receiver's, too many packets will +be received. The receiver MAY respond by skipping any packet (i.e., not +submitting the packet for decoding). This is likely to produce a less severe +artifact than if the frame were dropped after decoding. + + + +A decoder MAY employ a more sophisticated drift compensation method. For +example, the +NetEQ component +of the +Google WebRTC codebase +compensates for drift by adding or removing +one period when the signal is highly periodic. The reference implementation of +Opus allows a caller to learn whether the current frame's signal is highly +periodic, and if so what the period is, using the OPUS_GET_PITCH() request. + +
    + +
    + +
    + + +Switching between the Opus coding modes, audio bandwidths, and channel counts + requires careful consideration to avoid audible glitches. +Switching between any two configurations of the CELT-only mode, any two + configurations of the Hybrid mode, or from WB SILK to Hybrid mode does not + require any special treatment in the decoder, as the MDCT overlap will smooth + the transition. +Switching from Hybrid mode to WB SILK requires adding in the final contents + of the CELT overlap buffer to the first SILK-only packet. +This can be done by decoding a 2.5 ms silence frame with the CELT decoder + using the channel count of the SILK-only packet (and any choice of audio + bandwidth), which will correctly handle the cases when the channel count + changes as well. + + + +When changing the channel count for SILK-only or Hybrid packets, the encoder + can avoid glitches by smoothly varying the stereo width of the input signal + before or after the transition, and SHOULD do so. +However, other transitions between SILK-only packets or between NB or MB SILK + and Hybrid packets may cause glitches, because neither the LSF coefficients + nor the LTP, LPC, stereo unmixing, and resampler buffers are available at the + new sample rate. +These switches SHOULD be delayed by the encoder until quiet periods or + transients, where the inevitable glitches will be less audible. Additionally, + the bit-stream MAY include redundant side information ("redundancy"), in the + form of additional CELT frames embedded in each of the Opus frames around the + transition. + + + +The other transitions that cannot be easily handled are those where the lower + frequencies switch between the SILK LP-based model and the CELT MDCT model. +However, an encoder may not have an opportunity to delay such a switch to a + convenient point. +For example, if the content switches from speech to music, and the encoder does + not have enough latency in its analysis to detect this in advance, there may + be no convenient silence period during which to make the transition for quite + some time. +To avoid or reduce glitches during these problematic mode transitions, and + also between audio bandwidth changes in the SILK-only modes, transitions MAY + include redundant side information ("redundancy"), in the form of an + additional CELT frame embedded in the Opus frame. + + + +A transition between coding the lower frequencies with the LP model and the + MDCT model or a transition that involves changing the SILK bandwidth + is only normatively specified when it includes redundancy. +For those without redundancy, it is RECOMMENDED that the decoder use a + concealment technique (e.g., make use of a PLC algorithm) to "fill in" the + gap or discontinuity caused by the mode transition. +Therefore, PLC MUST NOT be applied during any normative transition, i.e., when + +A packet includes redundancy for this transition (as described below), +The transition is between any WB SILK packet and any Hybrid packet, or vice + versa, +The transition is between any two Hybrid mode packets, or +The transition is between any two CELT mode packets, + + unless there is actual packet loss. + + +
    + +Transitions with side information include an extra 5 ms "redundant" CELT + frame within the Opus frame. +This frame is designed to fill in the gap or discontinuity in the different + layers without requiring the decoder to conceal it. +For transitions from CELT-only to SILK-only or Hybrid, the redundant frame is + inserted in the first Opus frame after the transition (i.e., the first + SILK-only or Hybrid frame). +For transitions from SILK-only or Hybrid to CELT-only, the redundant frame is + inserted in the last Opus frame before the transition (i.e., the last + SILK-only or Hybrid frame). + + +
    + +The presence of redundancy is signaled in all SILK-only and Hybrid frames, not + just those involved in a mode transition. +This allows the frames to be decoded correctly even if an adjacent frame is + lost. +For SILK-only frames, this signaling is implicit, based on the size of the + of the Opus frame and the number of bits consumed decoding the SILK portion of + it. +After decoding the SILK portion of the Opus frame, the decoder uses ec_tell() + (see ) to check if there are at least 17 bits + remaining. +If so, then the frame contains redundancy. + + + +For Hybrid frames, this signaling is explicit. +After decoding the SILK portion of the Opus frame, the decoder uses ec_tell() + (see ) to ensure there are at least 37 bits remaining. +If so, it reads a symbol with the PDF in + , and if the value is 1, then the + frame contains redundancy. +Otherwise (if there were fewer than 37 bits left or the value was 0), the frame + does not contain redundancy. + + + +PDF +{4095, 1}/4096 + +
    + +
    + +Since the current frame is a SILK-only or a Hybrid frame, it must be at least + 10 ms. +Therefore, it needs an additional flag to indicate whether the redundant + 5 ms CELT frame should be mixed into the beginning of the current frame, + or the end. +After determining that a frame contains redundancy, the decoder reads a + 1 bit symbol with a uniform PDF + (). + + + +PDF +{1, 1}/2 + + + +If the value is zero, this is the first frame in the transition, and the + redundancy belongs at the end. +If the value is one, this is the second frame in the transition, and the + redundancy belongs at the beginning. +There is no way to specify that an Opus frame contains separate redundant CELT + frames at both the beginning and the end. + +
    + +
    + +Unlike the CELT portion of a Hybrid frame, the redundant CELT frame does not + use the same entropy coder state as the rest of the Opus frame, because this + would break the CELT bit allocation mechanism in Hybrid frames. +Thus, a redundant CELT frame always starts and ends on a byte boundary, even in + SILK-only frames, where this is not strictly necessary. + + + +For SILK-only frames, the number of bytes in the redundant CELT frame is simply + the number of whole bytes remaining, which must be at least 2, due to the + space check in . +For Hybrid frames, the number of bytes is equal to 2, plus a decoded unsigned + integer less than 256 (see ). +This may be more than the number of whole bytes remaining in the Opus frame, + in which case the frame is invalid. +However, a decoder is not required to ignore the entire frame, as this may be + the result of a bit error that desynchronized the range coder. +There may still be useful data before the error, and a decoder MAY keep any + audio decoded so far instead of invoking the PLC, but it is RECOMMENDED that + the decoder stop decoding and discard the rest of the current Opus frame. + + + +It would have been possible to avoid these invalid states in the design of Opus + by limiting the range of the explicit length decoded from Hybrid frames by the + actual number of whole bytes remaining. +However, this would require an encoder to determine the rate allocation for the + MDCT layer up front, before it began encoding that layer. +By allowing some invalid sizes, the encoder is able to defer that decision + until much later. +When encoding Hybrid frames which do not include redundancy, the encoder must + still decide up-front if it wishes to use the minimum 37 bits required to + trigger encoding of the redundancy flag, but this is a much looser + restriction. + + + +After determining the size of the redundant CELT frame, the decoder reduces + the size of the buffer currently in use by the range coder by that amount. +The CELT layer read any raw bits from the end of this reduced buffer, and all + calculations of the number of bits remaining in the buffer must be done using + this new, reduced size, rather than the original size of the Opus frame. + +
    + +
    + +The redundant frame is decoded like any other CELT-only frame, with the + exception that it does not contain a TOC byte. +The frame size is fixed at 5 ms, the channel count is set to that of the + current frame, and the audio bandwidth is also set to that of the current + frame, with the exception that for MB SILK frames, it is set to WB. + + + +If the redundancy belongs at the beginning (in a CELT-only to SILK-only or + Hybrid transition), the final reconstructed output uses the first 2.5 ms + of audio output by the decoder for the redundant frame as-is, discarding + the corresponding output from the SILK-only or Hybrid portion of the frame. +The remaining 2.5 ms is cross-lapped with the decoded SILK/Hybrid signal + using the CELT's power-complementary MDCT window to ensure a smooth + transition. + + + +If the redundancy belongs at the end (in a SILK-only or Hybrid to CELT-only + transition), only the second half (2.5 ms) of the audio output by the + decoder for the redundant frame is used. +In that case, the second half of the redundant frame is cross-lapped with the + end of the SILK/Hybrid signal, again using CELT's power-complementary MDCT + window to ensure a smooth transition. + +
    + +
    + +
    + +When a transition occurs, the state of the SILK or the CELT decoder (or both) + may need to be reset before decoding a frame in the new mode. +This avoids reusing "out of date" memory, which may not have been updated in + some time or may not be in a well-defined state due to, e.g., PLC. +The SILK state is reset before every SILK-only or Hybrid frame where the + previous frame was CELT-only. +The CELT state is reset every time the operating mode changes and the new mode + is either Hybrid or CELT-only, except when the transition uses redundancy as + described above. +When switching from SILK-only or Hybrid to CELT-only with redundancy, the CELT + state is reset before decoding the redundant CELT frame embedded in the + SILK-only or Hybrid frame, but it is not reset before decoding the following + CELT-only frame. +When switching from CELT-only mode to SILK-only or Hybrid mode with redundancy, + the CELT decoder is not reset for decoding the redundant CELT frame. + +

    + +
    + + + + + + +
    + +Just like the decoder, the Opus encoder also normally consists of two main blocks: the +SILK encoder and the CELT encoder. However, unlike the case of the decoder, a valid +(though potentially suboptimal) Opus encoder is not required to support all modes and +may thus only include a SILK encoder module or a CELT encoder module. +The output bit-stream of the Opus encoding contains bits from the SILK and CELT + encoders, though these are not separable due to the use of a range coder. +A block diagram of the encoder is illustrated below. + +
    + +| Rate |--->| Encoder | V + +-----------+ | | Conversion | | | +---------+ + | Optional | | +------------+ +---------+ | Range | +->| High-pass |--+ | Encoder |----> + | Filter | | +--------------+ +---------+ | | Bit- + +-----------+ | | Delay | | CELT | +---------+ stream + +->| Compensation |->| Encoder | ^ + | | | |------+ + +--------------+ +---------+ +]]> + +
    +     + + +For a normal encoder where both the SILK and the CELT modules are included, an optimal +encoder should select which coding mode to use at run-time depending on the conditions. +In the reference implementation, the frame size is selected by the application, but the +other configuration parameters (number of channels, bandwidth, mode) are automatically +selected (unless explicitly overridden by the application) depend on the following: + +Requested bitrate +Input sampling rate +Type of signal (speech vs music) +Frame size in use + + +The type of signal currently needs to be provided by the application (though it can be +changed in real-time). An Opus encoder implementation could also do automatic detection, +but since Opus is an interactive codec, such an implementation would likely have to either +delay the signal (for non-interactive applications) or delay the mode switching decisions (for +interactive applications). + + + +When the encoder is configured for voice over IP applications, the input signal is +filtered by a high-pass filter to remove the lowest part of the spectrum +that contains little speech energy and may contain background noise. This is a second order +Auto Regressive Moving Average (i.e., with poles and zeros) filter with a cut-off frequency around 50 Hz. +In the future, a music detector may also be used to lower the cut-off frequency when the +input signal is detected to be music rather than speech. + + +
    + +The range coder acts as the bit-packer for Opus. +It is used in three different ways: to encode + + +Entropy-coded symbols with a fixed probability model using ec_encode() + (entenc.c), + + +Integers from 0 to (2**M - 1) using ec_enc_uint() or ec_enc_bits() + (entenc.c), + +Integers from 0 to (ft - 1) (where ft is not a power of two) using + ec_enc_uint() (entenc.c). + + + + + +The range encoder maintains an internal state vector composed of the four-tuple + (val, rng, rem, ext) representing the low end of the current + range, the size of the current range, a single buffered output byte, and a + count of additional carry-propagating output bytes. +Both val and rng are 32-bit unsigned integer values, rem is a byte value or + less than 255 or the special value -1, and ext is an unsigned integer with at + least 11 bits. +This state vector is initialized at the start of each each frame to the value + (0, 2**31, -1, 0). +After encoding a sequence of symbols, the value of rng in the encoder should + exactly match the value of rng in the decoder after decoding the same sequence + of symbols. +This is a powerful tool for detecting errors in either an encoder or decoder + implementation. +The value of val, on the other hand, represents different things in the encoder + and decoder, and is not expected to match. + + + +The decoder has no analog for rem and ext. +These are used to perform carry propagation in the renormalization loop below. +Each iteration of this loop produces 9 bits of output, consisting of 8 data + bits and a carry flag. +The encoder cannot determine the final value of the output bytes until it + propagates these carry flags. +Therefore the reference implementation buffers a single non-propagating output + byte (i.e., one less than 255) in rem and keeps a count of additional + propagating (i.e., 255) output bytes in ext. +An implementation may choose to use any mathematically equivalent scheme to + perform carry propagation. + + +
    + +The main encoding function is ec_encode() (entenc.c), which encodes symbol k in + the current context using the same three-tuple (fl[k], fh[k], ft) + as the decoder to describe the range of the symbol (see + ). + + +ec_encode() updates the state of the encoder as follows. +If fl[k] is greater than zero, then +
    + +
    +Otherwise, val is unchanged and +
    + +
    +The divisions here are integer division. +     + +
    + +After this update, the range is normalized using a procedure very similar to + that of , implemented by + ec_enc_normalize() (entenc.c). +The following process is repeated until rng > 2**23. +First, the top 9 bits of val, (val>>23), are sent to the carry buffer, + described in . +Then, the encoder sets +
    + +
    +     +
    + +
    + +The function ec_enc_carry_out() (entenc.c) implements carry propagation and + output buffering. +It takes as input a 9-bit value, c, consisting of 8 data bits and an additional + carry bit. +If c is equal to the value 255, then ext is simply incremented, and no other + state updates are performed. +Otherwise, let b = (c>>8) be the carry bit. +Then, + + +If the buffered byte rem contains a value other than -1, the encoder outputs + the byte (rem + b). +Otherwise, if rem is -1, no byte is output. + + +If ext is non-zero, then the encoder outputs ext bytes---all with a value of 0 + if b is set, or 255 if b is unset---and sets ext to 0. + + +rem is set to the 8 data bits: +
    + +
    +     +     +     +
    + +
    + +
    + +The reference implementation uses three additional encoding methods that are + exactly equivalent to the above, but make assumptions and simplifications that + allow for a more efficient implementation. + + +
    + +The first is ec_encode_bin() (entenc.c), defined using the parameter ftb + instead of ft. +It is mathematically equivalent to calling ec_encode() with + ft = (1<<ftb), but avoids using division. + +
    + +
    + +The next is ec_enc_bit_logp() (entenc.c), which encodes a single binary symbol. +The context is described by a single parameter, logp, which is the absolute + value of the base-2 logarithm of the probability of a "1". +It is mathematically equivalent to calling ec_encode() with the 3-tuple + (fl[k] = 0, fh[k] = (1<<logp) - 1, + ft = (1<<logp)) if k is 0 and with + (fl[k] = (1<<logp) - 1, + fh[k] = ft = (1<<logp)) if k is 1. +The implementation requires no multiplications or divisions. + +
    + +
    + +The last is ec_enc_icdf() (entenc.c), which encodes a single binary symbol with + a table-based context of up to 8 bits. +This uses the same icdf table as ec_dec_icdf() from + . +The function is mathematically equivalent to calling ec_encode() with + fl[k] = (1<<ftb) - icdf[k-1] (or 0 if + k == 0), fh[k] = (1<<ftb) - icdf[k], and + ft = (1<<ftb). +This only saves a few arithmetic operations over ec_encode_bin(), but allows + the encoder to use the same icdf tables as the decoder. + +
    + +
    + +
    + +The raw bits used by the CELT layer are packed at the end of the buffer using + ec_enc_bits() (entenc.c). +Because the raw bits may continue into the last byte output by the range coder + if there is room in the low-order bits, the encoder must be prepared to merge + these values into a single byte. +The procedure in does this in a way that + ensures both the range coded data and the raw bits can be decoded + successfully. + +
    + +
    + +The function ec_enc_uint() (entenc.c) encodes one of ft equiprobable symbols in + the range 0 to (ft - 1), inclusive, each with a frequency of 1, + where ft may be as large as (2**32 - 1). +Like the decoder (see ), it splits up the + value into a range coded symbol representing up to 8 of the high bits, and, if + necessary, raw bits representing the remainder of the value. + + +ec_enc_uint() takes a two-tuple (t, ft), where t is the value to be + encoded, 0 <= t < ft, and ft is not necessarily a + power of two. +Let ftb = ilog(ft - 1), i.e., the number of bits required + to store (ft - 1) in two's complement notation. +If ftb is 8 or less, then t is encoded directly using ec_encode() with the + three-tuple (t, t + 1, ft). + + +If ftb is greater than 8, then the top 8 bits of t are encoded using the + three-tuple (t>>(ftb - 8), + (t>>(ftb - 8)) + 1, + ((ft - 1)>>(ftb - 8)) + 1), and the + remaining bits, + (t & ((1<<(ftb - 8)) - 1), + are encoded as raw bits with ec_enc_bits(). + +
    + +
    + +After all symbols are encoded, the stream must be finalized by outputting a + value inside the current range. +Let end be the integer in the interval [val, val + rng) with the + largest number of trailing zero bits, b, such that + (end + (1<<b) - 1) is also in the interval + [val, val + rng). +This choice of end allows the maximum number of trailing bits to be set to + arbitrary values while still ensuring the range coded part of the buffer can + be decoded correctly. +Then, while end is not zero, the top 9 bits of end, i.e., (end>>23), are + passed to the carry buffer in accordance with the procedure in + , and end is updated via +
    + +
    +Finally, if the buffered output byte, rem, is neither zero nor the special + value -1, or the carry count, ext, is greater than zero, then 9 zero bits are + sent to the carry buffer to flush it to the output buffer. +When outputting the final byte from the range coder, if it would overlap any + raw bits already packed into the end of the output buffer, they should be ORed + into the same byte. +The bit allocation routines in the CELT layer should ensure that this can be + done without corrupting the range coder data so long as end is chosen as + described above. +If there is any space between the end of the range coder data and the end of + the raw bits, it is padded with zero bits. +This entire process is implemented by ec_enc_done() (entenc.c). +     +
    + +
    + + The bit allocation routines in Opus need to be able to determine a + conservative upper bound on the number of bits that have been used + to encode the current frame thus far. This drives allocation + decisions and ensures that the range coder and raw bits will not + overflow the output buffer. This is computed in the + reference implementation to whole-bit precision by + the function ec_tell() (entcode.h) and to fractional 1/8th bit + precision by the function ec_tell_frac() (entcode.c). + Like all operations in the range coder, it must be implemented in a + bit-exact manner, and must produce exactly the same value returned by + the same functions in the decoder after decoding the same symbols. + +
    + +
    + +
    + + In many respects the SILK encoder mirrors the SILK decoder described + in . + Details such as the quantization and range coder tables can be found + there, while this section describes the high-level design choices that + were made. + The diagram below shows the basic modules of the SILK encoder. +
    + +| Rate |--->| Mixing |--->| Core |----------> +Input |Conversion| | | | Encoder | Bitstream + +----------+ +--------+ +---------+ +]]> + +
    +     + +
    + +The input signal's sampling rate is adjusted by a sample rate conversion +module so that it matches the SILK internal sampling rate. +The input to the sample rate converter is delayed by a number of samples +depending on the sample rate ratio, such that the overall delay is constant +for all input and output sample rates. + +
    + +
    + +The stereo mixer is only used for stereo input signals. +It converts a stereo left/right signal into an adaptive +mid/side representation. +The first step is to compute non-adaptive mid/side signals +as half the sum and difference between left and right signals. +The side signal is then minimized in energy by subtracting a +prediction of it based on the mid signal. +This prediction works well when the left and right signals +exhibit linear dependency, for instance for an amplitude-panned +input signal. +Like in the decoder, the prediction coefficients are linearly +interpolated during the first 8 ms of the frame. + The mid signal is always encoded, whereas the residual + side signal is only encoded if it has sufficient + energy compared to the mid signal's energy. + If it has not, + the "mid_only_flag" is set without encoding the side signal. + + +The predictor coefficients are coded regardless of whether +the side signal is encoded. +For each frame, two predictor coefficients are computed, one +that predicts between low-passed mid and side channels, and +one that predicts between high-passed mid and side channels. +The low-pass filter is a simple three-tap filter +and creates a delay of one sample. +The high-pass filtered signal is the difference between +the mid signal delayed by one sample and the low-passed +signal. Instead of explicitly computing the high-passed +signal, it is computationally more efficient to transform +the prediction coefficients before applying them to the +filtered mid signal, as follows +
    + + + +
    +where w0 and w1 are the low-pass and high-pass prediction +coefficients, mid(n-1) is the mid signal delayed by one sample, +LP(n) and HP(n) are the low-passed and high-passed +signals and pred(n) is the prediction signal that is subtracted +from the side signal. +     +
    + +
    + +What follows is a description of the core encoder and its components. +For simplicity, the core encoder is referred to simply as the encoder in +the remainder of this section. An overview of the encoder is given in +. + +

    + +The input signal is processed by a Voice Activity Detector (VAD) to produce +a measure of voice activity, spectral tilt, and signal-to-noise estimates for +each frame. The VAD uses a sequence of half-band filterbanks to split the +signal into four subbands: 0...Fs/16, Fs/16...Fs/8, Fs/8...Fs/4, and +Fs/4...Fs/2, where Fs is the sampling frequency (8, 12, 16, or 24 kHz). +The lowest subband, from 0 - Fs/16, is high-pass filtered with a first-order +moving average (MA) filter (with transfer function H(z) = 1-z**(-1)) to +reduce the energy at the lowest frequencies. For each frame, the signal +energy per subband is computed. +In each subband, a noise level estimator tracks the background noise level +and a Signal-to-Noise Ratio (SNR) value is computed as the logarithm of the +ratio of energy to noise level. +Using these intermediate variables, the following parameters are calculated +for use in other SILK modules: + + +Average SNR.

    +The pitch analysis finds a binary voiced/unvoiced classification, and, for +frames classified as voiced, four pitch lags per frame - one for each +5 ms subframe - and a pitch correlation indicating the periodicity of +the signal. +The input is first whitened using a Linear Prediction (LP) whitening filter, +where the coefficients are computed through standard Linear Prediction Coding +(LPC) analysis. The order of the whitening filter is 16 for best results, but +is reduced to 12 for medium complexity and 8 for low complexity modes. +The whitened signal is analyzed to find pitch lags for which the time +correlation is high. +The analysis consists of three stages for reducing the complexity: + +In the first stage, the whitened signal is downsampled to 4 kHz +(from 8 kHz) and the current frame is correlated to a signal delayed +by a range of lags, starting from a shortest lag corresponding to +500 Hz, to a longest lag corresponding to 56 Hz. + + +The second stage operates on an 8 kHz signal (downsampled from 12, 16, +or 24 kHz) and measures time correlations only near the lags +corresponding to those that had sufficiently high correlations in the first +stage. The resulting correlations are adjusted for a small bias towards +short lags to avoid ending up with a multiple of the true pitch lag. +The highest adjusted correlation is compared to a threshold depending on: + + +Whether the previous frame was classified as voiced + + +The speech activity level + + +The spectral tilt. + + +If the threshold is exceeded, the current frame is classified as voiced and +the lag with the highest adjusted correlation is stored for a final pitch +analysis of the highest precision in the third stage. + + +The last stage operates directly on the whitened input signal to compute time +correlations for each of the four subframes independently in a narrow range +around the lag with highest correlation from the second stage. + + +     +
    + +
    + +The noise shaping analysis finds gains and filter coefficients used in the +prefilter and noise shaping quantizer. These parameters are chosen such that +they will fulfill several requirements: + + +Balancing quantization noise and bitrate. +The quantization gains determine the step size between reconstruction levels +of the excitation signal. Therefore, increasing the quantization gain +amplifies quantization noise, but also reduces the bitrate by lowering +the entropy of the quantization indices. + + +Spectral shaping of the quantization noise; the noise shaping quantizer is +capable of reducing quantization noise in some parts of the spectrum at the +cost of increased noise in other parts without substantially changing the +bitrate. +By shaping the noise such that it follows the signal spectrum, it becomes +less audible. In practice, best results are obtained by making the shape +of the noise spectrum slightly flatter than the signal spectrum. + + +De-emphasizing spectral valleys; by using different coefficients in the +analysis and synthesis part of the prefilter and noise shaping quantizer, +the levels of the spectral valleys can be decreased relative to the levels +of the spectral peaks such as speech formants and harmonics. +This reduces the entropy of the signal, which is the difference between the +coded signal and the quantization noise, thus lowering the bitrate. + + +Matching the levels of the decoded speech formants to the levels of the +original speech formants; an adjustment gain and a first order tilt +coefficient are computed to compensate for the effect of the noise +shaping quantization on the level and spectral tilt. + + + + +

    + shows an example of an +input signal spectrum (1). +After de-emphasis and level matching, the spectrum has deeper valleys (2). +The quantization noise spectrum (3) more or less follows the input signal +spectrum, while having slightly less pronounced peaks. +The entropy, which provides a lower bound on the bitrate for encoding the +excitation signal, is proportional to the area between the de-emphasized +spectrum (2) and the quantization noise spectrum (3). Without de-emphasis, +the entropy is proportional to the area between input spectrum (1) and +quantization noise (3) - clearly higher. +     + + +The transformation from input signal to de-emphasized signal can be +described as a filtering operation with a filter +
    + + + +
    +having an adjustment gain G, a first order tilt adjustment filter with +tilt coefficient c_tilt, and where +
    + + + +
    +is the analysis part of the de-emphasis filter, consisting of the short-term +shaping filter with coefficients a_ana(k), and the long-term shaping filter +with coefficients b_ana(k) and pitch lag L. +The parameter d determines the number of long-term shaping filter taps. +     + + +Similarly, but without the tilt adjustment, the synthesis part can be written as +
    + + + +
    +     + +All noise shaping parameters are computed and applied per subframe of 5 ms. +First, an LPC analysis is performed on a windowed signal block of 15 ms. +The signal block has a look-ahead of 5 ms relative to the current subframe, +and the window is an asymmetric sine window. The LPC analysis is done with the +autocorrelation method, with an order of between 8, in lowest-complexity mode, +and 16, for best quality. + + +Optionally the LPC analysis and noise shaping filters are warped by replacing +the delay elements by first-order allpass filters. +This increases the frequency resolution at low frequencies and reduces it at +high ones, which better matches the human auditory system and improves +quality. +The warped analysis and filtering comes at a cost in complexity +and is therefore only done in higher complexity modes. + + +The quantization gain is found by taking the square root of the residual energy +from the LPC analysis and multiplying it by a value inversely proportional +to the coding quality control parameter and the pitch correlation. + + +Next the two sets of short-term noise shaping coefficients a_ana(k) and +a_syn(k) are obtained by applying different amounts of bandwidth expansion to the +coefficients found in the LPC analysis. +This bandwidth expansion moves the roots of the LPC polynomial towards the +origin, using the formulas +
    + + + +
    +where a(k) is the k'th LPC coefficient, and the bandwidth expansion factors +g_ana and g_syn are calculated as +
    + + + +
    +where C is the coding quality control parameter between 0 and 1. +Applying more bandwidth expansion to the analysis part than to the synthesis +part gives the desired de-emphasis of spectral valleys in between formants. +     + + +The long-term shaping is applied only during voiced frames. +It uses three filter taps, described by +
    + + + +
    +For unvoiced frames these coefficients are set to 0. The multiplication factors +F_ana and F_syn are chosen between 0 and 1, depending on the coding quality +control parameter, as well as the calculated pitch correlation and smoothed +subband SNR of the lowest subband. By having F_ana less than F_syn, +the pitch harmonics are emphasized relative to the valleys in between the +harmonics. +     + + +The tilt coefficient c_tilt is for unvoiced frames chosen as +
    + + + +
    +and as +
    + + + +
    +for voiced frames, where V is the voice activity level between 0 and 1. +     + +The adjustment gain G serves to correct any level mismatch between the original +and decoded signals that might arise from the noise shaping and de-emphasis. +This gain is computed as the ratio of the prediction gain of the short-term +analysis and synthesis filter coefficients. The prediction gain of an LPC +synthesis filter is the square root of the output energy when the filter is +excited by a unit-energy impulse on the input. +An efficient way to compute the prediction gain is by first computing the +reflection coefficients from the LPC coefficients through the step-down +algorithm, and extracting the prediction gain from the reflection coefficients +as +
    + + + +
    +where r_k is the k'th reflection coefficient. +     + + +Initial values for the quantization gains are computed as the square-root of +the residual energy of the LPC analysis, adjusted by the coding quality control +parameter. +These quantization gains are later adjusted based on the results of the +prediction analysis. + +
    + +
    + +The prediction analysis is performed in one of two ways depending on how +the pitch estimator classified the frame. +The processing for voiced and unvoiced speech is described in + and + , respectively. + Inputs to this function include the pre-whitened signal from the + pitch estimator (see ). + + +
    + + For a frame of voiced speech the pitch pulses will remain dominant in the + pre-whitened input signal. + Further whitening is desirable as it leads to higher quality at the same + available bitrate. + To achieve this, a Long-Term Prediction (LTP) analysis is carried out to + estimate the coefficients of a fifth-order LTP filter for each of four + subframes. + The LTP coefficients are quantized using the method described in + , and the quantized LTP + coefficients are used to compute the LTP residual signal. + This LTP residual signal is the input to an LPC analysis where the LPC coefficients are + estimated using Burg's method , such that the residual energy is minimized. + The estimated LPC coefficients are converted to a Line Spectral Frequency (LSF) vector + and quantized as described in . +After quantization, the quantized LSF vector is converted back to LPC +coefficients using the full procedure in . +By using quantized LTP coefficients and LPC coefficients derived from the +quantized LSF coefficients, the encoder remains fully synchronized with the +decoder. +The quantized LPC and LTP coefficients are also used to filter the input +signal and measure residual energy for each of the four subframes. + +
    +
    + +For a speech signal that has been classified as unvoiced, there is no need +for LTP filtering, as it has already been determined that the pre-whitened +input signal is not periodic enough within the allowed pitch period range +for LTP analysis to be worth the cost in terms of complexity and bitrate. +The pre-whitened input signal is therefore discarded, and instead the input +signal is used for LPC analysis using Burg's method. +The resulting LPC coefficients are converted to an LSF vector and quantized +as described in the following section. +They are then transformed back to obtain quantized LPC coefficients, which +are then used to filter the input signal and measure residual energy for +each of the four subframes. + +
    + +The main purpose of linear prediction in SILK is to reduce the bitrate by +minimizing the residual energy. +At least at high bitrates, perceptual aspects are handled +independently by the noise shaping filter. +Burg's method is used because it provides higher prediction gain +than the autocorrelation method and, unlike the covariance method, +produces stable filters (assuming numerical errors don't spoil +that). SILK's implementation of Burg's method is also computationally +faster than the autocovariance method. +The implementation of Burg's method differs from traditional +implementations in two aspects. +The first difference is that it +operates on autocorrelations, similar to the Schur algorithm , but +with a simple update to the autocorrelations after finding each +reflection coefficient to make the result identical to Burg's method. +This brings down the complexity of Burg's method to near that of +the autocorrelation method. +The second difference is that the signal in each subframe is scaled +by the inverse of the residual quantization step size. Subframes with +a small quantization step size will on average spend more bits for a +given amount of residual energy than subframes with a large step size. +Without scaling, Burg's method minimizes the total residual energy in +all subframes, which doesn't necessarily minimize the total number of +bits needed for coding the quantized residual. The residual energy +of the scaled subframes is a better measure for that number of +bits. + +
    +
    +
    + +
    + +Unlike many other speech codecs, SILK uses variable bitrate coding +for the LSFs. +This improves the average rate-distortion (R-D) tradeoff and reduces outliers. +The variable bitrate coding minimizes a linear combination of the weighted +quantization errors and the bitrate. +The weights for the quantization errors are the Inverse +Harmonic Mean Weighting (IHMW) function proposed by Laroia et al. +(see ). +These weights are referred to here as Laroia weights. + + +The LSF quantizer consists of two stages. +The first stage is an (unweighted) vector quantizer (VQ), with a +codebook size of 32 vectors. +The quantization errors for the codebook vector are sorted, and +for the N best vectors a second stage quantizer is run. +By varying the number N a tradeoff is made between R-D performance +and computational efficiency. +For each of the N codebook vectors the Laroia weights corresponding +to that vector (and not to the input vector) are calculated. +Then the residual between the input LSF vector and the codebook +vector is scaled by the square roots of these Laroia weights. +This scaling partially normalizes error sensitivity for the +residual vector, so that a uniform quantizer with fixed +step sizes can be used in the second stage without too much +performance loss. +And by scaling with Laroia weights determined from the first-stage +codebook vector, the process can be reversed in the decoder. + + +The second stage uses predictive delayed decision scalar +quantization. +The quantization error is weighted by Laroia weights determined +from the LSF input vector. +The predictor multiplies the previous quantized residual value +by a prediction coefficient that depends on the vector index from the +first stage VQ and on the location in the LSF vector. +The prediction is subtracted from the LSF residual value before +quantizing the result, and added back afterwards. +This subtraction can be interpreted as shifting the quantization levels +of the scalar quantizer, and as a result the quantization error of +each value depends on the quantization decision of the previous value. +This dependency is exploited by the delayed decision mechanism to +search for a quantization sequency with best R-D performance +with a Viterbi-like algorithm . +The quantizer processes the residual LSF vector in reverse order +(i.e., it starts with the highest residual LSF value). +This is done because the prediction works slightly +better in the reverse direction. + + +The quantization index of the first stage is entropy coded. +The quantization sequence from the second stage is also entropy +coded, where for each element the probability table is chosen +depending on the vector index from the first stage and the location +of that element in the LSF vector. + + +
    + +If the input is stable, finding the best candidate usually results in a +quantized vector that is also stable. Because of the two-stage approach, +however, it is possible that the best quantization candidate is unstable. +The encoder applies the same stabilization procedure applied by the decoder + (see to ensure the LSF parameters + are within their valid range, increasingly sorted, and have minimum + distances between each other and the border values. + +
    +
    + +
    + +For voiced frames, the prediction analysis described in + resulted in four sets +(one set per subframe) of five LTP coefficients, plus four weighting matrices. +The LTP coefficients for each subframe are quantized using entropy constrained +vector quantization. +A total of three vector codebooks are available for quantization, with +different rate-distortion trade-offs. The three codebooks have 10, 20, and +40 vectors and average rates of about 3, 4, and 5 bits per vector, respectively. +Consequently, the first codebook has larger average quantization distortion at +a lower rate, whereas the last codebook has smaller average quantization +distortion at a higher rate. +Given the weighting matrix W_ltp and LTP vector b, the weighted rate-distortion +measure for a codebook vector cb_i with rate r_i is give by +
    + + + +
    +where u is a fixed, heuristically-determined parameter balancing the distortion +and rate. +Which codebook gives the best performance for a given LTP vector depends on the +weighting matrix for that LTP vector. +For example, for a low valued W_ltp, it is advantageous to use the codebook +with 10 vectors as it has a lower average rate. +For a large W_ltp, on the other hand, it is often better to use the codebook +with 40 vectors, as it is more likely to contain the best codebook vector. +The weighting matrix W_ltp depends mostly on two aspects of the input signal. +The first is the periodicity of the signal; the more periodic, the larger W_ltp. +The second is the change in signal energy in the current subframe, relative to +the signal one pitch lag earlier. +A decaying energy leads to a larger W_ltp than an increasing energy. +Both aspects fluctuate relatively slowly, which causes the W_ltp matrices for +different subframes of one frame often to be similar. +Because of this, one of the three codebooks typically gives good performance +for all subframes, and therefore the codebook search for the subframe LTP +vectors is constrained to only allow codebook vectors to be chosen from the +same codebook, resulting in a rate reduction. +     + + +To find the best codebook, each of the three vector codebooks is +used to quantize all subframe LTP vectors and produce a combined +weighted rate-distortion measure for each vector codebook. +The vector codebook with the lowest combined rate-distortion +over all subframes is chosen. The quantized LTP vectors are used +in the noise shaping quantizer, and the index of the codebook +plus the four indices for the four subframe codebook vectors +are passed on to the range encoder. + +
    + +
    + +In the prefilter the input signal is filtered using the spectral valley +de-emphasis filter coefficients from the noise shaping analysis +(see ). +By applying only the noise shaping analysis filter to the input signal, +it provides the input to the noise shaping quantizer. + +
    + +
    + +The noise shaping quantizer independently shapes the signal and coding noise +spectra to obtain a perceptually higher quality at the same bitrate. + + +The prefilter output signal is multiplied with a compensation gain G computed +in the noise shaping analysis. Then the output of a synthesis shaping filter +is added, and the output of a prediction filter is subtracted to create a +residual signal. +The residual signal is multiplied by the inverse quantized quantization gain +from the noise shaping analysis, and input to a scalar quantizer. +The quantization indices of the scalar quantizer represent a signal of pulses +that is input to the pyramid range encoder. +The scalar quantizer also outputs a quantization signal, which is multiplied +by the quantized quantization gain from the noise shaping analysis to create +an excitation signal. +The output of the prediction filter is added to the excitation signal to form +the quantized output signal y(n). +The quantized output signal y(n) is input to the synthesis shaping and +prediction filters. + + +Optionally the noise shaping quantizer operates in a delayed decision +mode. +In this mode it uses a Viterbi algorithm to keep track of +multiple rounding choices in the quantizer and select the best +one after a delay of 32 samples. This improves the rate/distortion +performance of the quantizer. + +
    + +
    + + SILK was designed to run in Variable Bitrate (VBR) mode. However + the reference implementation also has a Constant Bitrate (CBR) mode + for SILK. In CBR mode SILK will attempt to encode each packet with + no more than the allowed number of bits. The Opus wrapper code + then pads the bitstream if any unused bits are left in SILK mode, or + encodes the high band with the remaining number of bits in Hybrid mode. + The number of payload bits is adjusted by changing + the quantization gains and the rate/distortion tradeoff in the noise + shaping quantizer, in an iterative loop + around the noise shaping quantizer and entropy coding. + Compared to the SILK VBR mode, the CBR mode has lower + audio quality at a given average bitrate, and also has higher + computational complexity. + +
    + +
    + +
    + + +
    + +Most of the aspects of the CELT encoder can be directly derived from the description +of the decoder. For example, the filters and rotations in the encoder are simply the +inverse of the operation performed by the decoder. Similarly, the quantizers generally +optimize for the mean square error (because noise shaping is part of the bit-stream itself), +so no special search is required. For this reason, only the less straightforward aspects of the +encoder are described here. + + +
    +The pitch prefilter is applied after the pre-emphasis. It is applied +in such a way as to be the inverse of the decoder's post-filter. The main non-obvious aspect of the +prefilter is the selection of the pitch period. The pitch search should be optimized for the +following criteria: + +continuity: it is important that the pitch period +does not change abruptly between frames; and +avoidance of pitch multiples: when the period used is a multiple of the real period +(lower frequency fundamental), the post-filter loses most of its ability to reduce noise + + +
    + +
    + +The MDCT output is divided into bands that are designed to match the ear's critical +bands for the smallest (2.5 ms) frame size. The larger frame sizes use integer +multiples of the 2.5 ms layout. For each band, the encoder +computes the energy that will later be encoded. Each band is then normalized by the +square root of the unquantized energy, such that each band now forms a unit vector X. +The energy and the normalization are computed by compute_band_energies() +and normalise_bands() (bands.c), respectively. + +
    + +
    + + +Energy quantization (both coarse and fine) can be easily understood from the decoding process. +For all useful bitrates, the coarse quantizer always chooses the quantized log energy value that +minimizes the error for each band. Only at very low rate does the encoder allow larger errors to +minimize the rate and avoid using more bits than are available. When the +available CPU requirements allow it, it is best to try encoding the coarse energy both with and without +inter-frame prediction such that the best prediction mode can be selected. The optimal mode depends on +the coding rate, the available bitrate, and the current rate of packet loss. + + +The fine energy quantizer always chooses the quantized log energy value that +minimizes the error for each band because the rate of the fine quantization depends only +on the bit allocation and not on the values that are coded. + +
    + +
    +The encoder must use exactly the same bit allocation process as used by the decoder +and described in . The three mechanisms that can be used by the +encoder to adjust the bitrate on a frame-by-frame basis are band boost, allocation trim, +and band skipping. + + +
    +The reference encoder makes a decision to boost a band when the energy of that band is significantly +higher than that of the neighboring bands. Let E_j be the log-energy of band j, we define + +D_j = 2*E_j - E_j-1 - E_j+1 + + +The allocation of band j is boosted once if D_j > t1 and twice if D_j > t2. For LM>=1, t1=2 and t2=4, +while for LM<1, t1=3 and t2=5. + + +
    + +
    +The allocation trim is a value between 0 and 10 (inclusively) that controls the allocation +balance between the low and high frequencies. The encoder starts with a safe "default" of 5 +and deviates from that default in two different ways. First the trim can deviate by +/- 2 +depending on the spectral tilt of the input signal. For signals with more low frequencies, the +trim is increased by up to 2, while for signals with more high frequencies, the trim is +decreased by up to 2. +For stereo inputs, the trim value can +be decreased by up to 4 when the inter-channel correlation at low frequency (first 8 bands) +is high. +
    + +
    +The encoder uses band skipping to ensure that the shape of the bands is only coded +if there is at least 1/2 bit per sample available for the PVQ. If not, then no bit is allocated +and folding is used instead. To ensure continuity in the allocation, some amount of hysteresis is +added to the process, such that a band that received PVQ bits in the previous frame only needs 7/16 +bit/sample to be coded for the current frame, while a band that did not receive PVQ bits in the +previous frames needs at least 9/16 bit/sample to be coded. +
    + +
    + +
    +Because CELT applies mid-side stereo coupling in the normalized domain, it does not suffer from +important stereo image problems even when the two channels are completely uncorrelated. For this reason +it is always safe to use stereo coupling on any audio frame. That being said, there are some frames +for which dual (independent) stereo is still more efficient. This decision is made by comparing the estimated +entropy with and without coupling over the first 13 bands, taking into account the fact that all bands with +more than two MDCT bins require one extra degree of freedom when coded in mid-side. Let L1_ms and L1_lr +be the L1-norm of the mid-side vector and the L1-norm of the left-right vector, respectively. The decision +to use mid-side is made if and only if +
    + +
    +where bins is the number of MDCT bins in the first 13 bands and E is the number of extra degrees of +freedom for mid-side coding. For LM>1, E=13, otherwise E=5. +     + +The reference encoder decides on the intensity stereo threshold based on the bitrate alone. After +taking into account the frame size by subtracting 80 bits per frame for coarse energy, the first +band using intensity coding is as follows: + + + +bitrate (kb/s) +start band +<35 8 +35-50 12 +50-68 16 +84-84 18 +84-102 19 +102-130 20 +>130 disabled + + + +
    + +
    + +The choice of time-frequency resolution used in is based on +R-D optimization. The distortion is the L1-norm (sum of absolute values) of each band +after each TF resolution under consideration. The L1 norm is used because it represents the entropy +for a Laplacian source. The number of bits required to code a change in TF resolution between +two bands is higher than the cost of having those two bands use the same resolution, which is +what requires the R-D optimization. The optimal decision is computed using the Viterbi algorithm. +See tf_analysis() in celt/celt.c. + +
    + +
    + +The choice of the spreading value in has an +impact on the nature of the coding noise introduced by CELT. The larger the f_r value, the +lower the impact of the rotation, and the more tonal the coding noise. The +more tonal the signal, the more tonal the noise should be, so the CELT encoder determines +the optimal value for f_r by estimating how tonal the signal is. The tonality estimate +is based on discrete pdf (4-bin histogram) of each band. Bands that have a large number of small +values are considered more tonal and a decision is made by combining all bands with more than +8 samples. See spreading_decision() in celt/bands.c. + +
    + +
    +CELT uses a Pyramid Vector Quantization (PVQ) +codebook for quantizing the details of the spectrum in each band that have not +been predicted by the pitch predictor. The PVQ codebook consists of all sums +of K signed pulses in a vector of N samples, where two pulses at the same position +are required to have the same sign. Thus the codebook includes +all integer codevectors y of N dimensions that satisfy sum(abs(y(j))) = K. + + + +In bands where there are sufficient bits allocated PVQ is used to encode +the unit vector that results from the normalization in + directly. Given a PVQ codevector y, +the unit vector X is obtained as X = y/||y||, where ||.|| denotes the +L2 norm. + + + +
    + + +The search for the best codevector y is performed by alg_quant() +(vq.c). There are several possible approaches to the +search, with a trade-off between quality and complexity. The method used in the reference +implementation computes an initial codeword y1 by projecting the normalized spectrum +X onto the codebook pyramid of K-1 pulses: + + +y0 = truncate_towards_zero( (K-1) * X / sum(abs(X))) + + + +Depending on N, K and the input data, the initial codeword y0 may contain from +0 to K-1 non-zero values. All the remaining pulses, with the exception of the last one, +are found iteratively with a greedy search that minimizes the normalized correlation +between y and X: +
    + +
    +     + + +The search described above is considered to be a good trade-off between quality +and computational cost. However, there are other possible ways to search the PVQ +codebook and the implementers MAY use any other search methods. See alg_quant() in celt/vq.c. + +
    + +
    + + +The vector to encode, X, is converted into an index i such that + 0 <= i < V(N,K) as follows. +Let i = 0 and k = 0. +Then for j = (N - 1) down to 0, inclusive, do: + + +If k > 0, set + i = i + (V(N-j-1,k-1) + V(N-j,k-1))/2. + +Set k = k + abs(X[j]). + +If X[j] < 0, set + i = i + (V(N-j-1,k) + V(N-j,k))/2. + + + + + +The index i is then encoded using the procedure in + with ft = V(N,K). + + +
    + +
    + + + + + +
    + +
    + + +
    + + +It is our intention to allow the greatest possible choice of freedom in +implementing the specification. For this reason, outside of the exceptions +noted in this section, conformance is defined through the reference +implementation of the decoder provided in . +Although this document includes an English description of the codec, should +the description contradict the source code of the reference implementation, +the latter shall take precedence. + + + +Compliance with this specification means that in addition to following the normative keywords in this document, + a decoder's output MUST also be + within the thresholds specified by the opus_compare.c tool (included + with the code) when compared to the reference implementation for each of the + test vectors provided (see ) and for each output + sampling rate and channel count supported. In addition, a compliant + decoder implementation MUST have the same final range decoder state as that of the + reference decoder. It is therefore RECOMMENDED that the + decoder implement the same functional behavior as the reference. + + A decoder implementation is not required to support all output sampling + rates or all output channel counts. + + +
    + +Using the reference code provided in , +a test vector can be decoded with + +opus_demo -d <rate> <channels> testvectorX.bit testX.out + +where <rate> is the sampling rate and can be 8000, 12000, 16000, 24000, or 48000, and +<channels> is 1 for mono or 2 for stereo. + + + +If the range decoder state is incorrect for one of the frames, the decoder will exit with +"Error: Range coder state mismatch between encoder and decoder". If the decoder succeeds, then +the output can be compared with the "reference" output with + +opus_compare -s -r <rate> testvectorX.dec testX.out + +for stereo or + +opus_compare -r <rate> testvectorX.dec testX.out + +for mono. + + +In addition to indicating whether the test vector comparison passes, the opus_compare tool +outputs an "Opus quality metric" that indicates how well the tested decoder matches the +reference implementation. A quality of 0 corresponds to the passing threshold, while +a quality of 100 is the highest possible value and means that the output of the tested decoder is identical to the reference +implementation. The passing threshold (quality 0) was calibrated in such a way that it corresponds to +additive white noise with a 48 dB SNR (similar to what can be obtained on a cassette deck). +It is still possible for an implementation to sound very good with such a low quality measure +(e.g. if the deviation is due to inaudible phase distortion), but unless this is verified by +listening tests, it is RECOMMENDED that implementations achieve a quality above 90 for 48 kHz +decoding. For other sampling rates, it is normal for the quality metric to be lower +(typically as low as 50 even for a good implementation) because of harmless mismatch with +the delay and phase of the internal sampling rate conversion. + + + +On POSIX environments, the run_vectors.sh script can be used to verify all test +vectors. This can be done with + +run_vectors.sh <exec path> <vector path> <rate> + +where <exec path> is the directory where the opus_demo and opus_compare executables +are built and <vector path> is the directory containing the test vectors. + +
    + +
    + +Opus Custom is an OPTIONAL part of the specification that is defined to +handle special sample rates and frame rates that are not supported by the +main Opus specification. Use of Opus Custom is discouraged for all but very +special applications for which a frame size different from 2.5, 5, 10, or 20 ms is +needed (for either complexity or latency reasons). Because Opus Custom is +optional, streams encoded using Opus Custom cannot be expected to be decodable by all Opus +implementations. Also, because no in-band mechanism exists for specifying the sampling +rate and frame size of Opus Custom streams, out-of-band signaling is required. +In Opus Custom operation, only the CELT layer is available, using the opus_custom_* function +calls in opus_custom.h. + +
    + +
    + +
    + + +Implementations of the Opus codec need to take appropriate security considerations +into account, as outlined in . +It is extremely important for the decoder to be robust against malicious +payloads. +Malicious payloads must not cause the decoder to overrun its allocated memory + or to take an excessive amount of resources to decode. +Although problems +in encoders are typically rarer, the same applies to the encoder. Malicious +audio streams must not cause the encoder to misbehave because this would +allow an attacker to attack transcoding gateways. + + +The reference implementation contains no known buffer overflow or cases where + a specially crafted packet or audio segment could cause a significant increase + in CPU load. +However, on certain CPU architectures where denormalized floating-point + operations are much slower than normal floating-point operations, it is + possible for some audio content (e.g., silence or near-silence) to cause an + increase in CPU load. +Denormals can be introduced by reordering operations in the compiler and depend + on the target architecture, so it is difficult to guarantee that an implementation + avoids them. +For architectures on which denormals are problematic, adding very small + floating-point offsets to the affected signals to prevent significant numbers + of denormalized operations is RECOMMENDED. +Alternatively, it is often possible to configure the hardware to treat + denormals as zero (DAZ). +No such issue exists for the fixed-point reference implementation. + +The reference implementation was validated in the following conditions: + + +Sending the decoder valid packets generated by the reference encoder and + verifying that the decoder's final range coder state matches that of the + encoder. + + +Sending the decoder packets generated by the reference encoder and then + subjected to random corruption. + +Sending the decoder random packets. + +Sending the decoder packets generated by a version of the reference encoder + modified to make random coding decisions (internal fuzzing), including mode + switching, and verifying that the range coder final states match. + + +In all of the conditions above, both the encoder and the decoder were run + inside the Valgrind memory + debugger, which tracks reads and writes to invalid memory regions as well as + the use of uninitialized memory. +There were no errors reported on any of the tested conditions. + +

    + +This appendix contains the complete source code for the +reference implementation of the Opus codec written in C. By default, +this implementation relies on floating-point arithmetic, but it can be +compiled to use only fixed-point arithmetic by defining the FIXED_POINT +macro. Information on building and using the reference implementation is +available in the README file. + + +The implementation can be compiled with either a C89 or a C99 +compiler. It is reasonably optimized for most platforms such that +only architecture-specific optimizations are likely to be useful. +The FFT used is a slightly modified version of the KISS-FFT library, +but it is easy to substitute any other FFT library. + + + +While the reference implementation does not rely on any +undefined behavior as defined by C89 or C99, +it relies on common implementation-defined behavior +for two's complement architectures: + +Right shifts of negative values are consistent with two's complement arithmetic, so that a>>b is equivalent to floor(a/(2**b)), +For conversion to a signed integer of N bits, the value is reduced modulo 2**N to be within range of the type, +The result of integer division of a negative value is truncated towards zero, and +The compiler provides a 64-bit integer type (a C99 requirement which is supported by most C89 compilers). + + + + +In its current form, the reference implementation also requires the following +architectural characteristics to obtain acceptable performance: + +Two's complement arithmetic, +At least a 16 bit by 16 bit integer multiplier (32-bit result), and +At least a 32-bit adder/accumulator. + + + + +

    + +To use the internal framing described in , the decoder + must know the total length of the Opus packet, in bytes. +This section describes a simple variation of that framing which can be used + when the total length of the packet is not known. +Nothing in the encoding of the packet itself allows a decoder to distinguish + between the regular, undelimited framing and the self-delimiting framing + described in this appendix. +Which one is used and where must be established by context at the transport + layer. +It is RECOMMENDED that a transport layer choose exactly one framing scheme, + rather than allowing an encoder to signal which one it wants to use. + + + +For example, although a regular Opus stream does not support more than two + channels, a multi-channel Opus stream may be formed from several one- and + two-channel streams. +To pack an Opus packet from each of these streams together in a single packet + at the transport layer, one could use the self-delimiting framing for all but + the last stream, and then the regular, undelimited framing for the last one. +Reverting to the undelimited framing for the last stream saves overhead + (because the total size of the transport-layer packet will still be known), + and ensures that a "multi-channel" stream which only has a single Opus stream + uses the same framing as a regular Opus stream does. +This avoids the need for signaling to distinguish these two cases. + + + +The self-delimiting framing is identical to the regular, undelimited framing + from , except that each Opus packet contains one extra + length field, encoded using the same one- or two-byte scheme from + . +This extra length immediately precedes the compressed data of the first Opus + frame in the packet, and is interpreted in the various modes as follows: + + +Code 0 packets: It is the length of the single Opus frame (see + ). + + +Code 1 packets: It is the length used for both of the Opus frames (see + ). + + +Code 2 packets: It is the length of the second Opus frame (see + ). + +CBR Code 3 packets: It is the length used for all of the Opus frames (see + ). + +VBR Code 3 packets: It is the length of the last Opus frame (see + ). + + + + +

    + + Opus is a speech and audio codec developed within the + IETF Internet Wideband Audio Codec working group. The codec + has a very low algorithmic delay and it + is highly scalable in terms of audio bandwidth, bitrate, and + complexity. Further, it provides different modes to efficiently encode speech signals + as well as music signals, thus making it the codec of choice for + various applications using the Internet or similar networks. + + + This document defines the Real-time Transport Protocol (RTP) + payload format for packetization + of Opus encoded speech and audio data necessary to + integrate Opus in the + most compatible way. It also provides an applicability statement + for the use of Opus over RTP. + Further, it describes media type registrations for + the RTP payload format. + +
    + +
    + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in . + + + The range of audio frequecies being coded + Constant bitrate + Central Processing Unit + Discontinuous transmission + Forward error correction + Internet Protocol + Speech or audio samples (per channel) + Session Description Protocol + Variable bitrate + + + + Throughout this document, we refer to the following definitions: + + + Abbreviation + Name + Audio Bandwidth (Hz) + Sampling Rate (Hz) + NB + Narrowband + 0 - 4000 + 8000 + + MB + Mediumband + 0 - 6000 + 12000 + + WB + Wideband + 0 - 8000 + 16000 + + SWB + Super-wideband + 0 - 12000 + 24000 + + FB + Fullband + 0 - 20000 + 48000 + + + Audio bandwidth naming + + +
    + +
    + + Opus encodes speech + signals as well as general audio signals. Two different modes can be + chosen, a voice mode or an audio mode, to allow the most efficient coding + depending on the type of the input signal, the sampling frequency of the + input signal, and the intended application. + + + + The voice mode allows efficient encoding of voice signals at lower bit + rates while the audio mode is optimized for general audio signals at medium and + higher bitrates. + + + + Opus is highly scalable in terms of audio + bandwidth, bitrate, and complexity. Further, Opus allows + transmitting stereo signals with in-band signaling in the bit-stream. + + +
    + + Opus supports bitrates from 6 kb/s to 510 kb/s. + The bitrate can be changed dynamically within that range. + All + other parameters being + equal, higher bitrates result in higher audio quality. + +
    + + For a frame size of + 20 ms, these + are the bitrate "sweet spots" for Opus in various configurations: + + + 8-12 kb/s for NB speech, + 16-20 kb/s for WB speech, + 28-40 kb/s for FB speech, + 48-64 kb/s for FB mono music, and + 64-128 kb/s for FB stereo music. + + +
    +
    + + For the same average bitrate, variable bitrate (VBR) can achieve higher audio quality + than constant bitrate (CBR). For the majority of voice transmission applications, VBR + is the best choice. One reason for choosing CBR is the potential + information leak that might occur when encrypting the + compressed stream. See for guidelines on when VBR is + appropriate for encrypted audio communications. In the case where an existing + VBR stream needs to be converted to CBR for security reasons, then the Opus padding + mechanism described in is the RECOMMENDED way to achieve padding + because the RTP padding bit is unencrypted. + + + The bitrate can be adjusted at any point in time. To avoid congestion, + the average bitrate SHOULD NOT exceed the available + network bandwidth. If no target bitrate is specified, the bitrates specified in + are RECOMMENDED. + + +
    + +
    + + + Opus can, as described in , + be operated with a variable bitrate. In that case, the encoder will + automatically reduce the bitrate for certain input signals, like periods + of silence. When using continuous transmission, it will reduce the + bitrate when the characteristics of the input signal permit, but + will never interrupt the transmission to the receiver. Therefore, the + received signal will maintain the same high level of audio quality over the + full duration of a transmission while minimizing the average bit + rate over time. + + + + In cases where the bitrate of Opus needs to be reduced even + further or in cases where only constant bitrate is available, + the Opus encoder can use discontinuous + transmission (DTX), where parts of the encoded signal that + correspond to periods of silence in the input speech or audio signal + are not transmitted to the receiver. A receiver can distinguish + between DTX and packet loss by looking for gaps in the sequence + number, as described by Section 4.1 + of . + + + + On the receiving side, the non-transmitted parts will be handled by a + frame loss concealment unit in the Opus decoder which generates a + comfort noise signal to replace the non transmitted parts of the + speech or audio signal. Use of Comfort + Noise (CN) with Opus is discouraged. + The transmitter MUST drop whole frames only, + based on the size of the last transmitted frame, + to ensure successive RTP timestamps differ by a multiple of 120 and + to allow the receiver to use whole frames for concealment. + + + + DTX can be used with both variable and constant bitrate. + It will have a slightly lower speech or audio + quality than continuous transmission. Therefore, using continuous + transmission is RECOMMENDED unless constraints on available network bandwidth + are severe. + + +
    + +
    + +
    + + + Complexity of the encoder can be scaled to optimize for CPU resources in real-time, mostly as + a trade-off between audio quality and bitrate. Also, different modes of Opus have different complexity. + + +
    + +
    + + + The voice mode of Opus allows for embedding "in-band" forward error correction (FEC) + data into the Opus bit stream. This FEC scheme adds + redundant information about the previous packet (N-1) to the current + output packet N. For + each frame, the encoder decides whether to use FEC based on (1) an + externally-provided estimate of the channel's packet loss rate; (2) an + externally-provided estimate of the channel's capacity; (3) the + sensitivity of the audio or speech signal to packet loss; (4) whether + the receiving decoder has indicated it can take advantage of "in-band" + FEC information. The decision to send "in-band" FEC information is + entirely controlled by the encoder and therefore no special precautions + for the payload have to be taken. + + + + On the receiving side, the decoder can take advantage of this + additional information when it loses a packet and the next packet + is available. In order to use the FEC data, the jitter buffer needs + to provide access to payloads with the FEC data. + Instead of performing loss concealment for a missing packet, the + receiver can then configure its decoder to decode the FEC data from the next packet. + + + + Any compliant Opus decoder is capable of ignoring + FEC information when it is not needed, so encoding with FEC cannot cause + interoperability problems. + However, if FEC cannot be used on the receiving side, then FEC + SHOULD NOT be used, as it leads to an inefficient usage of network + resources. Decoder support for FEC SHOULD be indicated at the time a + session is set up. + + +
    + +
    + + + Opus allows for transmission of stereo audio signals. This operation + is signaled in-band in the Opus bit-stream and no special arrangement + is needed in the payload format. An + Opus decoder is capable of handling a stereo encoding, but an + application might only be capable of consuming a single audio + channel. + + + If a decoder cannot take advantage of the benefits of a stereo signal + this SHOULD be indicated at the time a session is set up. In that case + the sending side SHOULD NOT send stereo signals as it leads to an + inefficient usage of network resources. + + +
    + +
    + +
    + The payload format for Opus consists of the RTP header and Opus payload + data. +
    + The format of the RTP header is specified in . + The use of the fields of the RTP header by the Opus payload format is + consistent with that specification. + + The payload length of Opus is an integer number of octets and + therefore no padding is necessary. The payload MAY be padded by an + integer number of octets according to , + although the Opus internal padding is preferred. + + The timestamp, sequence number, and marker bit (M) of the RTP header + are used in accordance with Section 4.1 + of . + + The RTP payload type for Opus is to be assigned dynamically. + + The receiving side MUST be prepared to receive duplicate RTP + packets. The receiver MUST provide at most one of those payloads to the + Opus decoder for decoding, and MUST discard the others. + + Opus supports 5 different audio bandwidths, which can be adjusted during + a stream. + The RTP timestamp is incremented with a 48000 Hz clock rate + for all modes of Opus and all sampling rates. + The unit + for the timestamp is samples per single (mono) channel. The RTP timestamp corresponds to the + sample time of the first encoded sample in the encoded frame. + For data encoded with sampling rates other than 48000 Hz, + the sampling rate has to be adjusted to 48000 Hz. + +
    + +
    + + The Opus encoder can output encoded frames representing 2.5, 5, 10, 20, + 40, or 60 ms of speech or audio data. Further, an arbitrary number of frames can be + combined into a packet, up to a maximum packet duration representing + 120 ms of speech or audio data. The grouping of one or more Opus + frames into a single Opus packet is defined in Section 3 of + . An RTP payload MUST contain exactly one + Opus packet as defined by that document. + + + shows the structure combined with the RTP header. + +

    + +
    + + The target bitrate of Opus can be adjusted at any point in time, thus + allowing efficient congestion control. Furthermore, the amount + of encoded speech or audio data encoded in a + single packet can be used for congestion control, since the transmission + rate is inversely proportional to the packet duration. A lower packet + transmission rate reduces the amount of header overhead, but at the same + time increases latency and loss sensitivity, so it ought to be used with + care. + + Since UDP does not provide congestion control, applications that use + RTP over UDP SHOULD implement their own congestion control above the + UDP layer . Work in the rmcat working group + describes the + interactions and conceptual interfaces necessary between the application + components that relate to congestion control, including the RTP layer, + the higher-level media codec control layer, and the lower-level + transport interface, as well as components dedicated to congestion + control functions. +
    + +
    + One media subtype (audio/opus) has been defined and registered as + described in the following section. + +
    + Media type registration is done according to and . + + Type name: audio + Subtype name: opus + + Required parameters: + + the RTP timestamp is incremented with a + 48000 Hz clock rate for all modes of Opus and all sampling + rates. For data encoded with sampling rates other than 48000 Hz, + the sampling rate has to be adjusted to 48000 Hz. + + + + Optional parameters: + + + + a hint about the maximum output sampling rate that the receiver is + capable of rendering in Hz. + The decoder MUST be capable of decoding + any audio bandwidth but due to hardware limitations only signals + up to the specified sampling rate can be played back. Sending signals + with higher audio bandwidth results in higher than necessary network + usage and encoding complexity, so an encoder SHOULD NOT encode + frequencies above the audio bandwidth specified by maxplaybackrate. + This parameter can take any value between 8000 and 48000, although + commonly the value will match one of the Opus bandwidths + (). + By default, the receiver is assumed to have no limitations, i.e. 48000. + + + + + a hint about the maximum input sampling rate that the sender is likely to produce. + This is not a guarantee that the sender will never send any higher bandwidth + (e.g. it could send a pre-recorded prompt that uses a higher bandwidth), but it + indicates to the receiver that frequencies above this maximum can safely be discarded. + This parameter is useful to avoid wasting receiver resources by operating the audio + processing pipeline (e.g. echo cancellation) at a higher rate than necessary. + This parameter can take any value between 8000 and 48000, although + commonly the value will match one of the Opus bandwidths + (). + By default, the sender is assumed to have no limitations, i.e. 48000. + + + + the maximum duration of media represented + by a packet (according to Section 6 of + ) that a decoder wants to receive, in + milliseconds rounded up to the next full integer value. + Possible values are 3, 5, 10, 20, 40, 60, or an arbitrary + multiple of an Opus frame size rounded up to the next full integer + value, up to a maximum value of 120, as + defined in . If no value is + specified, the default is 120. + + + the preferred duration of media represented + by a packet (according to Section 6 of + ) that a decoder wants to receive, in + milliseconds rounded up to the next full integer value. + Possible values are 3, 5, 10, 20, 40, 60, or an arbitrary + multiple of an Opus frame size rounded up to the next full integer + value, up to a maximum value of 120, as defined in . If no value is + specified, the default is 20. + + + specifies the maximum average + receive bitrate of a session in bits per second (b/s). The actual + value of the bitrate can vary, as it is dependent on the + characteristics of the media in a packet. Note that the maximum + average bitrate MAY be modified dynamically during a session. Any + positive integer is allowed, but values outside the range + 6000 to 510000 SHOULD be ignored. If no value is specified, the + maximum value specified in + for the corresponding mode of Opus and corresponding maxplaybackrate + is the default. + + + specifies whether the decoder prefers receiving stereo or mono signals. + Possible values are 1 and 0 where 1 specifies that stereo signals are preferred, + and 0 specifies that only mono signals are preferred. + Independent of the stereo parameter every receiver MUST be able to receive and + decode stereo signals but sending stereo signals to a receiver that signaled a + preference for mono signals may result in higher than necessary network + utilization and encoding complexity.

    + The information described in the media type specification has a + specific mapping to fields in the Session Description Protocol (SDP) + , which is commonly used to describe RTP + sessions. When SDP is used to specify sessions employing Opus, + the mapping is as follows: + + + + The media type ("audio") goes in SDP "m=" as the media name. + + The media subtype ("opus") goes in SDP "a=rtpmap" as the encoding + name. The RTP clock rate in "a=rtpmap" MUST be 48000 and the number of + channels MUST be 2. + + The OPTIONAL media type parameters "ptime" and "maxptime" are + mapped to "a=ptime" and "a=maxptime" attributes, respectively, in the + SDP. + + The OPTIONAL media type parameters "maxaveragebitrate", + "maxplaybackrate", "stereo", "cbr", "useinbandfec", and + "usedtx", when present, MUST be included in the "a=fmtp" attribute + in the SDP, expressed as a media type string in the form of a + semicolon-separated list of parameter=value pairs (e.g., + maxplaybackrate=48000). They MUST NOT be specified in an + SSRC-specific "fmtp" source-level attribute (as defined in + Section 6.3 of ). + + The OPTIONAL media type parameters "sprop-maxcapturerate", + and "sprop-stereo" MAY be mapped to the "a=fmtp" SDP attribute by + copying them directly from the media type parameter string as part + of the semicolon-separated list of parameter=value pairs (e.g., + sprop-stereo=1). These same OPTIONAL media type parameters MAY also + be specified using an SSRC-specific "fmtp" source-level attribute + as described in Section 6.3 of . + They MAY be specified in both places, in which case the parameter + in the source-level attribute overrides the one found on the + "a=fmtp" line. The value of any parameter which is not specified in + a source-level source attribute MUST be taken from the "a=fmtp" + line, if it is present there. + + + + + Below are some examples of SDP session descriptions for Opus: + + Example 1: Standard mono session with 48000 Hz clock rate +

    + + When using the offer-answer procedure described in to negotiate the use of Opus, the following + considerations apply: + + + + Opus supports several clock rates. For signaling purposes only + the highest, i.e. 48000, is used. The actual clock rate of the + corresponding media is signaled inside the payload and is not + restricted by this payload format description. The decoder MUST be + capable of decoding every received clock rate. An example + is shown below: + +
    + + + +
    +     + + The "ptime" and "maxptime" parameters are unidirectional + receive-only parameters and typically will not compromise + interoperability; however, some values might cause application + performance to suffer. defines the SDP offer-answer handling of the + "ptime" parameter. The "maxptime" parameter MUST be handled in the + same way. + + + The "maxplaybackrate" parameter is a unidirectional receive-only + parameter that reflects limitations of the local receiver. When + sending to a single destination, a sender MUST NOT use an audio + bandwidth higher than necessary to make full use of audio sampled at + a sampling rate of "maxplaybackrate". Gateways or senders that + are sending the same encoded audio to multiple destinations + SHOULD NOT use an audio bandwidth higher than necessary to + represent audio sampled at "maxplaybackrate", as this would lead + to inefficient use of network resources. + The "maxplaybackrate" parameter does not + affect interoperability. Also, this parameter SHOULD NOT be used + to adjust the audio bandwidth as a function of the bitrate, as this + is the responsibility of the Opus encoder implementation. + + + The "maxaveragebitrate" parameter is a unidirectional receive-only + parameter that reflects limitations of the local receiver. The sender + of the other side MUST NOT send with an average bitrate higher than + "maxaveragebitrate" as it might overload the network and/or + receiver. The "maxaveragebitrate" parameter typically will not + compromise interoperability; however, some values might cause + application performance to suffer, and ought to be set with + care. + + The "sprop-maxcapturerate" and "sprop-stereo" parameters are + unidirectional sender-only parameters that reflect limitations of + the sender side. + They allow the receiver to set up a reduced-complexity audio + processing pipeline if the sender is not planning to use the full + range of Opus's capabilities. + Neither "sprop-maxcapturerate" nor "sprop-stereo" affect + interoperability and the receiver MUST be capable of receiving any signal. + + + + The "stereo" parameter is a unidirectional receive-only + parameter. When sending to a single destination, a sender MUST + NOT use stereo when "stereo" is 0. Gateways or senders that are + sending the same encoded audio to multiple destinations SHOULD + NOT use stereo when "stereo" is 0, as this would lead to + inefficient use of network resources. The "stereo" parameter does + not affect interoperability. + + + + The "cbr" parameter is a unidirectional receive-only + parameter. + + + The "useinbandfec" parameter is a unidirectional receive-only + parameter. + + The "usedtx" parameter is a unidirectional receive-only + parameter. + + Any unknown parameter in an offer MUST be ignored by the receiver + and MUST be removed from the answer. + +     + + + The Opus parameters in an SDP Offer/Answer exchange are completely + orthogonal, and there is no relationship between the SDP Offer and + the Answer. + +
    + +
    + + For declarative use of SDP such as in Session Announcement Protocol + (SAP), , and RTSP, , for + Opus, the following needs to be considered: + + + + The values for "maxptime", "ptime", "maxplaybackrate", and + "maxaveragebitrate" ought to be selected carefully to ensure that a + reasonable performance can be achieved for the participants of a session. + + + The values for "maxptime", "ptime", and of the payload + format configuration are recommendations by the decoding side to ensure + the best performance for the decoder. + + + All other parameters of the payload format configuration are declarative + and a participant MUST use the configurations that are provided for + the session. More than one configuration can be provided if necessary + by declaring multiple RTP payload types; however, the number of types + ought to be kept small. + +
    +
    + +
    + + Use of variable bitrate (VBR) is subject to the security considerations in + . + + RTP packets using the payload format defined in this specification + are subject to the security considerations discussed in the RTP + specification , and in any applicable RTP profile such as + RTP/AVP , RTP/AVPF , + RTP/SAVP or RTP/SAVPF . + However, as "Securing the RTP Protocol Framework: + Why RTP Does Not Mandate a Single Media Security Solution" + discusses, it is not an RTP payload + format's responsibility to discuss or mandate what solutions are used + to meet the basic security goals like confidentiality, integrity and + source authenticity for RTP in general. This responsibility lays on + anyone using RTP in an application. They can find guidance on + available security mechanisms and important considerations in Options + for Securing RTP Sessions [I-D.ietf-avtcore-rtp-security-options]. + Applications SHOULD use one or more appropriate strong security + mechanisms. + + This payload format and the Opus encoding do not exhibit any + significant non-uniformity in the receiver-end computational load and thus + are unlikely to pose a denial-of-service threat due to the receipt of + pathological datagrams. +

The value of the PreSkip field shall be at least + 80 milliseconds' worth of PCM samples even when removing any number of Opus samples which may or may not + contain the priming samples. The PreSkip field is not used for discarding the priming samples at the whole + playback at all since it is informative only, and that task falls on the Edit List Box. + + InputSampleRate: + The InputSampleRate field shall be set to the same value as the *Input Sample Rate* field in the + identification header defined in Ogg Opus [3]. + + OutputGain: + The OutputGain field shall be set to the same value as the *Output Gain* field in the identification + header define in Ogg Opus [3].

Due to support more than + two channels, an Opus sample can contain frames from multiple Opus bitstreams but all Opus packets shall + share with the total of frame sizes in a single Opus sample. The way of how to pack an Opus packet from + each of Opus bitstreams into a single Opus sample follows Appendix B. in RFC 6716 [2]. + The endianness has nothing to do with any Opus sample since every Opus packet is processed byte-by-byte. + In this specification, 'sample' means 'Opus sample' except for 'padded samples', 'priming samples', 'valid + sample' and 'sample-accurate', i.e. 'sample' is 'sample' in the term defined in ISO/IEC 14496-12 [1]. + + +-----------------------------------------+-------------------------------------+ + | Opus packet 0 (self-delimiting framing) | Opus packet 1 (undelimited framing) | + +-----------------------------------------+-------------------------------------+ + |<---------------------------- the size of Opus sample ------------------------>| + + Figure 1 - Example structure of an Opus sample containing two Opus bitstreams + + 4.3.4 Duration of Opus sample + The duration of Opus sample is given by multiplying the total of frame sizes for a single Opus bitstream + expressed in seconds by the value of the timescale field in the Media Header Box. + Let's say an Opus sample consists of two Opus bitstreams, where the frame size of one bitstream is 40 milli- + seconds and the frame size of another is 60 milliseconds, and the timescale field in the Media Header Box + is set to 48000, then the duration of that Opus sample shall be 120 milliseconds since three 40 millisecond + frame and two 60 millisecond frames shall be contained because of the maximum duration of Opus packet, 120 + milliseconds, and 5760 in the timescale indicated in the Media Header Box. + + To indicate the valid samples excluding the padded samples at the end of Opus bitstream, the duration of + the last Opus sample of an Opus bitstream is given by multiplying the number of the valid samples by the + value produced by dividing the value of the timescale field in the Media Header Box by 48000. + + 4.3.5 Sub-sample + The structure of the last Opus packet in an Opus sample is different from the others in the same Opus sample, + and the others are invalid Opus packets as an Opus sample because of self-delimiting framing. To avoid + complexities, sub-sample is not defined for Opus sample in this specification. + + 4.3.6 Random Access + This subclause describes the nature of the random access of Opus sample. + + 4.3.6.1 Random Access Point + All Opus samples can be independently decoded i.e. every Opus sample is a sync sample. Therefore, the + Sync Sample Box shall not be present as long as there are no samples other than Opus samples in the same + track. And the sample_is_non_sync_sample field for Opus samples shall be set to 0. + + 4.3.6.2 Pre-roll + Opus bitstream requires at least 80 millisecond pre-roll after each random access to get correct output. + Pre-roll is indicated by the roll_distance field in AudioRollRecoveryEntry. AudioPreRollEntry shall not + be used since every Opus sample is a sync sample in Opus bitstream. Note that roll_distance is expressed + in sample units in a term of ISO Base Media File Format, and always takes negative values. + + For any track containing Opus bitstreams, at least one Sample Group Description Box and at least one + Sample to Group Box within the Sample Table Box shall be present and these have the grouping_type field + set to 'roll'. If any Opus sample is contained in a track fragment, the Sample to Group Box with the + grouping_type field set to 'roll' shall be present for that track fragment. + + For the requirement of AudioRollRecoveryEntry, the compatible_brands field in the File Type Box shall + contain at least one brand which requires support for roll groups. + + 4.4 Trimming of Actual Duration + Due to the priming samples (or the padding at the beginning) derived from the pre-roll for the startup and the + padded samples at the end, we need trim from media to get the actual duration. An edit in the Edit List Box can + achieve this demand, and the Edit Box and the Edit List Box shall be present. + + For sample-accurate trimming, proper timescale should be set to the timescale field in the Movie Header Box + and the Media Header Box inside Track Box(es) for Opus bitstream. The timescale field in the Media Header Box is + typically set to 48000. It is recommended that the timescale field in the Movie Header Box be set to the same + value of the timescale field in the Media Header Box in order to avoid the rounding problem when specifying + duration of edit if the timescales in all of the Media Header Boxes are set to the same value. + + For example, to indicate the actual duration of an Opus bitstream in a track with the timescale fields of both + the Movie Header Box and the Media Header Box set to 48000, we would use the following edit: + segment_duration = the number of the valid samples + media_time = the number of the priming samples + media_rate = 1 << 16 + + The Edit List Box is applied to whole movie including all movie fragments. Therefore, it is impossible to tell + the actual duration in the case producing movie fragments on the fly such as live-streaming. In such cases, + the duration of the last Opus sample may be helpful by setting zero to the segment_duration field since the + value 0 represents implicit duration equal to the sum of the duration of all samples. + + 4.5 Channel Mapping + 4.5.1 ISO Base Media native Channel Mapping + ISO Base Media File Format, that is ISO/IEC 14496-12 [1], defines an extension ChannelLayout to the + AudioSampleEntry, which conveys information of mapping channels to loudspeaker positions. The ChannelLayout + enables to specify the channel layout more flexibly than the predefined layouts of the ChannelMappingFamily. + + To utilize the ChannelLayout for OpusSampleEntry, the ChannelMappingFamily field should be set to 255. + Even when the ChannelMappingFamily field is set to another value, the assignment of each output channel to + loudspeaker position specified by the ChannelMappingFamily would be changed as specified by the ChannelLayout. + The procedure of the assignment is the following. + + 1. Decoded channels are mapped to output channels according to the ChannelMappingTable. + 2. Output channels are mapped to loudspeaker positions according to the ChannelLayout. + + In this way, the parameters of the Opus Specific Box are processed before the ChannelLayout, and the + ChannelLayout shall follow the Opus Specific Box. + + 4.5.2 Composition on all active tracks (informative) + By the application of alternate_group in the Track Header Box, whole audio channels in all active tracks from + non-alternate group and/or different alternate group from each other are composited into the presentation. If + an Opus sample consists of multiple Opus bitstreams, it can be splitted into individual Opus bitstreams and + reconstructed into new Opus samples as long as every Opus bitstream has the same total duration in each Opus + sample. This nature can be utilized to encapsulate a single Opus bitstream in each track without breaking the + original channel layout. + + As an example, let's say there is a following track: + OutputChannelCount = 6; + StreamCount = 4; + CoupledCount = 2; + ChannelMapping = {0, 4, 1, 2, 3, 5}; // front left, front center, front right, + // rear left, rear right, LFE + Here, to couple front left to front right channels into the first stream, and couple rear left to rear right + channels into the second stream, reordering is needed since coupled streams must precede any non-coupled + stream. You extract the four Opus bitstreams from this track and you encapsulate two of the four into a track + and the others into another track. The former track is as follows. + OutputChannelCount = 6; + StreamCount = 2; + CoupledCount = 2; + ChannelMapping = {0, 255, 1, 2, 3, 255}; // front left, front center, front right, + // rear left, rear right, LFE + And the latter track is as follows. + OutputChannelCount = 6; + StreamCount = 2; + CoupledCount = 0; + ChannelMapping = {255, 0, 255, 255, 255, 1}; // front left, front center, front right, + // rear left, rear right, LFE + In addition, the value of the alternate_group field in the both tracks is set to 0. As the result, the player + may play as if channels with 255 are not present, and play the presentation constructed from the both tracks + in the same channel layout as the one of the original track. Keep in mind that the way of the composition, i.e. + the mixing for playback, is not defined here, and maybe different results could occur except for the channel + layout of the original, depending on an implementation or the definition of a derived file format. + + Note that some derived file formats may specify the restriction to ignore alternate grouping. In the context + of such file formats, this application is not available. This unavailability does not mean incompatibilities + among file formats unless the restriction to the value of the alternate_group field is specified and brings + about any conflict among their definitions. + + 4.6 Basic Structure (informative) + 4.6.1 Initial Movie + This subclause shows a basic structure of the Movie Box as follows: + + +----+----+----+----+----+----+----+----+------------------------------+ + |moov| | | | | | | | Movie Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | |mvhd| | | | | | | Movie Header Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | |trak| | | | | | | Track Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | |tkhd| | | | | | Track Header Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | |edts| | | | | | Edit Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | |elst| | | | | Edit List Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | |mdia| | | | | | Media Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | |mdhd| | | | | Media Header Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | |hdlr| | | | | Handler Reference Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | |minf| | | | | Media Information Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | |smhd| | | | Sound Media Header Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | |dinf| | | | Data Information Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | |dref| | | Data Reference Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | | |url | | DataEntryUrlBox | + +----+----+----+----+----+----+ or +----+------------------------------+ + | | | | | | |urn | | DataEntryUrnBox | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | |stbl| | | | Sample Table | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | |stsd| | | Sample Description Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | | |Opus| | OpusSampleEntry | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | | | |dOps| Opus Specific Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | |stts| | | Decoding Time to Sample Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | |stsc| | | Sample To Chunk Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | |stsz| | | Sample Size Box | + +----+----+----+----+----+ or +----+----+------------------------------+ + | | | | | |stz2| | | Compact Sample Size Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | |stco| | | Chunk Offset Box | + +----+----+----+----+----+ or +----+----+------------------------------+ + | | | | | |co64| | | Chunk Large Offset Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | |sgpd| | | Sample Group Description Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | | | | |sbgp| | | Sample to Group Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | |mvex|* | | | | | | Movie Extends Box | + +----+----+----+----+----+----+----+----+------------------------------+ + | | |trex|* | | | | | Track Extends Box | + +----+----+----+----+----+----+----+----+------------------------------+ + + Figure 2 - Basic structure of Movie Box + + It is strongly recommended that the order of boxes should follow the above structure. + Boxes marked with an asterisk (*) may be present. + For most boxes listed above, the definition is as is defined in ISO/IEC 14496-12 [1].

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command `./configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX `make' updates targets which have the same time stamps as +their prerequisites, which makes it generally unusable when shipped +generated files such as `configure' are involved. Use GNU `make' +instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf limitation. Until the limitation is lifted, you can use +this workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. diff --git a/extern/portaudio/bindings/cpp/Makefile.am b/extern/portaudio/bindings/cpp/Makefile.am new file mode 100644 index 0000000..b10449c --- /dev/null +++ b/extern/portaudio/bindings/cpp/Makefile.am @@ -0,0 +1,7 @@ +SUBDIRS = lib include bin +#doc + +EXTRA_DIST = portaudiocpp.pc + +pkgconfigdir = $(libdir)/pkgconfig +pkgconfig_DATA = portaudiocpp.pc diff --git a/extern/portaudio/bindings/cpp/Makefile.in b/extern/portaudio/bindings/cpp/Makefile.in new file mode 100644 index 0000000..a397933 --- /dev/null +++ b/extern/portaudio/bindings/cpp/Makefile.in @@ -0,0 +1,848 @@ +# Makefile.in generated by automake 1.14.1 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994-2013 Free Software Foundation, Inc. + +# This Makefile.in is free software;

    PortAudioCpp - A Native C++ Binding of PortAudio V19

    +///

    PortAudio

    +///

    +/// PortAudio is a portable and mature C API for accessing audio hardware. It offers both callback-based and blocking +/// style input and output, deals with sample data format conversions, dithering and much more. There are a large number +/// of implementations available for various platforms including Windows MME, Windows DirectX, Windows and MacOS (Classic) +/// ASIO, MacOS Classic SoundManager, MacOS X CoreAudio, OSS (Linux), Linux ALSA, JACK (MacOS X and Linux) and SGI Irix +/// AL. Note that, currently not all of these implementations are equally complete or up-to-date (as PortAudio V19 is +/// still in development). Because PortAudio has a C API, it can easily be called from a variety of other programming +/// languages. +///

    +///

    PortAudioCpp

    +///

    +/// Although, it is possible to use PortAudio's C API from within a C++ program, this is usually a little awkward +/// as procedural and object-oriented paradigms need to be mixed. PortAudioCpp aims to resolve this by encapsulating +/// PortAudio's C API to form an equivalent object-oriented C++ API. It provides a more natural integration of PortAudio +/// into C++ programs as well as a more structured interface. PortAudio's concepts were preserved as much as possible and +/// no additional features were added except for some `convenience methods'. +///

    +///

    +/// PortAudioCpp's main features are: +///

      +///
    • Structured object model.
      • +///
    • C++ exception handling instead of C-style error return codes.
      • +///
    • Handling of callbacks using free functions (C and C++), static functions, member functions or instances of classes +/// derived from a given interface.
      • +///
    • STL compliant iterators to host APIs and devices.
      • +///
    • Some additional convenience functions to more easily set up and use PortAudio.
      • +///
    +///

    +///

    +/// PortAudioCpp requires a recent version of the PortAudio V19 source code. This can be obtained from CVS or as a snapshot +/// from the website. The examples also require the ASIO 2 SDK which can be obtained from the Steinberg website. Alternatively, the +/// examples can easily be modified to compile without needing ASIO. +///

    +///

    +/// Supported platforms: +///

      +///
    • Microsoft Visual C++ 6.0, 7.0 (.NET 2002) and 7.1 (.NET 2003).
      • +///
    • GNU G++ 2.95 and G++ 3.3.
      • +///
    +/// Other platforms should be easily supported as PortAudioCpp is platform-independent and (reasonably) C++ standard compliant. +///

    +///

    +/// This documentation mainly provides information specific to PortAudioCpp. For a more complete explaination of all of the +/// concepts used, please consult the PortAudio documentation. +///

    +///

    +/// PortAudioCpp was developed by Merlijn Blaauw with many great suggestions and help from Ross Bencina. Ludwig Schwardt provided +/// GNU/Linux build files and checked G++ compatibility. PortAudioCpp may be used under the same licensing, conditions and +/// warranty as PortAudio. See the PortAudio license for more details. +///

It describes how all of the PortAudio data types and functions fit together. It provides links to the documentation for each function and data type. You can find all of the detailed documentation for each API function and data type on the portaudio.h page. + +@section introduction Introduction + +PortAudio provides a uniform application programming interface (API) across all supported platforms. You can think of the PortAudio library as a wrapper that converts calls to the PortAudio API into calls to platform-specific native audio APIs. Operating systems often offer more than one native audio API and some APIs (such as JACK) may be available on multiple target operating systems. PortAudio supports all the major native audio APIs on each supported platform. The diagram below illustrates the relationship between your application, PortAudio, and the supported native audio APIs: + +@image html portaudio-external-architecture-diagram.png + +PortAudio provides a uniform interface to native audio APIs. However, it doesn't always provide totally uniform functionality. There are cases where PortAudio is limited by the capabilities of the underlying native audio API. For example, PortAudio doesn't provide sample rate conversion if you request a sample rate that is not supported by the native audio API. Another example is that the ASIO SDK only allows one device to be open at a time, so PortAudio/ASIO doesn't currently support opening multiple ASIO devices simultaneously. + +@section key_abstractions Key abstractions: Host APIs, Devices and Streams + +The PortAudio processing model includes three main abstractions: Host APIs, audio Devices and audio Streams. + +Host APIs represent platform-specific native audio APIs. Some examples of Host APIs are Core Audio on Mac OS, WMME and DirectSound on Windows and OSS and ALSA on Linux. The diagram in the previous section shows many of the supported native APIs. Sometimes it's useful to know which Host APIs you're dealing with, but it is easy to use PortAudio without ever interacting directly with the Host API abstraction. + +Devices represent individual hardware audio interfaces or audio ports on the host platform. Devices have names and certain capabilities such as supported sample rates and the number of supported input and output channels. PortAudio provides functions to enumerate available Devices and to query for Device capabilities. + +Streams manage active audio input and output from and to Devices. Streams may be half duplex (input or output) or full duplex (simultaneous input and output). Streams operate at a specific sample rate with particular sample formats, buffer sizes and internal buffering latencies. You specify these parameters when you open the Stream. Audio data is communicated between a Stream and your application via a user provided asynchronous callback function or by invoking synchronous read and write functions. + +PortAudio supports audio input and output in a variety of sample formats: 8, 16, 24 and 32 bit integer formats and 32 bit floating point, irrespective of the formats supported by the native audio API. PortAudio also supports multichannel buffers in both interleaved and non-interleaved (separate buffer per channel) formats and automatically performs conversion when necessary. If requested, PortAudio can clamp out-of range samples and/or dither to a native format. + +The PortAudio API offers the following functionality: +- Initialize and terminate the library +- Enumerate available Host APIs +- Enumerate available Devices either globally, or within each Host API +- Discover default or recommended Devices and Device settings +- Discover Device capabilities such as supported audio data formats and sample rates +- Create and control audio Streams to acquire audio from and output audio to Devices +- Provide Stream timing information to support synchronising audio with other parts of your application +- Retrieve version and error information. + +These functions are described in more detail below. + + +@section top_level_functions Initialization, termination and utility functions + +The PortAudio library must be initialized before it can be used and terminated to clean up afterwards. You initialize PortAudio by calling Pa_Initialize() and clean up by calling Pa_Terminate(). + +You can query PortAudio for version information using Pa_GetVersion() to get a numeric version number and Pa_GetVersionText() to get a string. + +The size in bytes of the various sample formats represented by the @ref PaSampleFormat enumeration can be obtained using Pa_GetSampleSize(). + +Pa_Sleep() sleeps for a specified number of milliseconds. This isn't intended for use in production systems; it's provided only as a simple portable way to implement tests and examples where the main thread sleeps while audio is acquired or played by an asynchronous callback function. + +@section host_apis Host APIs + +A Host API acts as a top-level grouping for all of the Devices offered by a single native platform audio API. Each Host API has a unique type identifier, a name, zero or more Devices, and nominated default input and output Devices. + +Host APIs are usually referenced by index: an integer of type @ref PaHostApiIndex that ranges between zero and Pa_GetHostApiCount() - 1. You can enumerate all available Host APIs by counting across this range. + +You can retrieve the index of the default Host API by calling Pa_GetDefaultHostApi(). + +Information about a Host API, such as it's name and default devices, is stored in a @ref PaHostApiInfo structure. You can retrieve a pointer to a particular Host API's @ref PaHostApiInfo structure by calling Pa_GetHostApiInfo() with the Host API's index as a parameter. + +Most PortAudio functions reference Host APIs by @ref PaHostApiIndex indices. Each Host API also has a unique type identifier defined in the @ref PaHostApiTypeId enumeration. +You can call Pa_HostApiTypeIdToHostApiIndex() to retrieve the current @ref PaHostApiIndex for a particular @ref PaHostApiTypeId. + +@section devices Devices + +A Device represents an audio endpoint provided by a particular native audio API. This usually corresponds to a specific input or output port on a hardware audio interface, or to the interface as a whole. Each Host API operates independently, so a single physical audio port may be addressable via different Devices exposed by different Host APIs. + +A Device has a name, is associated with a Host API, and has a maximum number of supported input and output channels. PortAudio provides recommended default latency values and a default sample rate for each Device. To obtain more detailed information about device capabilities you can call Pa_IsFormatSupported() to query whether it is possible to open a Stream using particular Devices, parameters and sample rate. + +Although each Device conceptually belongs to a specific Host API, most PortAudio functions and data structures refer to Devices using a global, Host API-independent index of type @ref PaDeviceIndex – an integer of that ranges between zero and Pa_GetDeviceCount() - 1. The reasons for this are partly historical but it also makes it easy for applications to ignore the Host API abstraction and just work with Devices and Streams. + +If you want to enumerate Devices belonging to a particular Host API you can count between 0 and PaHostApiInfo::deviceCount - 1. You can convert this Host API-specific index value to a global @ref PaDeviceIndex value by calling Pa_HostApiDeviceIndexToDeviceIndex(). + +Information about a Device is stored in a @ref PaDeviceInfo structure. You can retrieve a pointer to a Devices's @ref PaDeviceInfo structure by calling Pa_GetDeviceInfo() with the Device's index as a parameter. + +You can retrieve the indices of the global default input and output devices using Pa_GetDefaultInputDevice() and Pa_GetDefaultOutputDevice(). Default Devices for each Host API are stored in the Host API's @ref PaHostApiInfo structures. + +For an example of enumerating devices and printing information about their capabilities see the pa_devs.c program in the test directory of the PortAudio distribution. + +@section streams Streams + +A Stream represents an active flow of audio data between your application and one or more audio Devices. A Stream operates at a specific sample rate with specific sample formats and buffer sizes. + +@subsection io_methods I/O Methods: callback and read/write + +PortAudio offers two methods for communicating audio data between an open Stream and your Application: (1) an asynchronous callback interface, where PortAudio calls a user defined callback function when new audio data is available or required, and (2) synchronous read and write functions which can be used in a blocking or non-blocking manner. You choose between the two methods when you open a Stream. The two methods are discussed in more detail below. + +@subsection opening_and_closing_streams Opening and Closing Streams + +You call Pa_OpenStream() to open a Stream, specifying the Device(s) to use, the number of input and output channels, sample formats, suggested latency values and flags that control dithering, clipping and overflow handling. You specify many of these parameters in two PaStreamParameters structures, one for input and one for output. If you're using the callback I/O method you also pass a callback buffer size, callback function pointer and user data pointer. + +Devices may be full duplex (supporting simultaneous input and output) or half duplex (supporting input or output) – usually this reflects the structure of the underlying native audio API. When opening a Stream you can specify one full duplex Device for both input and output, or two different Devices for input and output. Some Host APIs only support full-duplex operation with a full-duplex device (e.g. ASIO) but most are able to aggregate two half duplex devices into a full duplex Stream. PortAudio requires that all devices specified in a call to Pa_OpenStream() belong to the same Host API. + +A successful call to Pa_OpenStream() creates a pointer to a @ref PaStream – an opaque handle representing the open Stream. All PortAudio API functions that operate on open Streams take a pointer to a @ref PaStream as their first parameter. + +PortAudio also provides Pa_OpenDefaultStream() – a simpler alternative to Pa_OpenStream() which you can use when you want to open the default audio Device(s) with default latency parameters. + +You call Pa_CloseStream() to close a Stream when you've finished using it. + +@subsection starting_and_stopping_streams Starting and Stopping Streams + +Newly opened Streams are initially stopped. You call Pa_StartStream() to start a Stream. You can stop a running Stream using Pa_StopStream() or Pa_AbortStream() (the Stop function plays out all internally queued audio data, while Abort tries to stop as quickly as possible). An open Stream can be started and stopped multiple times. You can call Pa_IsStreamStopped() to query whether a Stream is running or stopped. + +By calling Pa_SetStreamFinishedCallback() it is possible to register a special @ref PaStreamFinishedCallback that will be called when the Stream has completed playing any internally queued buffers. This can be used in conjunction with the @ref paComplete stream callback return value (see below) to avoid blocking on a call to Pa_StopStream() while queued audio data is still playing. + +@subsection callback_io_method The Callback I/O Method + +So-called 'callback Streams' operate by periodically invoking a callback function you supply to Pa_OpenStream(). The callback function must implement the @ref PaStreamCallback signature. It gets called by PortAudio every time PortAudio needs your application to consume or produce audio data. The callback is passed pointers to buffers containing the audio to process. The format (interleave, sample data type) and size of these buffers is determined by the parameters passed to Pa_OpenStream() when the Stream was opened. + +Stream callbacks usually return @ref paContinue to indicate that PortAudio should keep the stream running. It is possible to deactivate a Stream from the stream callback by returning either @ref paComplete or @ref paAbort. In this case the Stream enters a deactivated state after the last buffer has finished playing (@ref paComplete) or as soon as possible (@ref paAbort). You can detect the deactivated state by calling Pa_IsStreamActive() or by using Pa_SetStreamFinishedCallback() to subscribe to a stream finished notification. Note that even if the stream callback returns @ref paComplete it's still necessary to call Pa_StopStream() or Pa_AbortStream() to enter the stopped state. + +Many of the tests in the /tests directory of the PortAudio distribution implement PortAudio stream callbacks. For example see: patest_sine.c (audio output), patest_record.c (audio input), patest_wire.c (audio pass-through) and pa_fuzz.c (simple audio effects processing). + +IMPORTANT: The stream callback function often needs to operate with very high or real-time priority. As a result there are strict requirements placed on the type of code that can be executed in a stream callback. In general this means avoiding any code that might block, including: acquiring locks, calling OS API functions including allocating memory. With the exception of Pa_GetStreamCpuLoad() you may not call PortAudio API functions from within the stream callback. + +@subsection read_write_io_method The Read/Write I/O Method + +As an alternative to the callback I/O method, PortAudio provides a synchronous read/write interface for acquiring and playing audio. This can be useful for applications that don't require the lowest possibly latency, or don't warrant the increased complexity of synchronising with an asynchronous callback funciton. This I/O method is also useful when calling PortAudio from programming languages that don't support asynchronous callbacks. + +To open a Stream in read/write mode you pass a NULL stream callback function pointer to Pa_OpenStream(). + +To write audio data to a Stream call Pa_WriteStream() and to read data call Pa_ReadStream(). These functions will block if the internal buffers are full, making them safe to call in a tight loop. If you want to avoid blocking you can query the amount of available read or write space using Pa_GetStreamReadAvailable() or Pa_GetStreamWriteAvailable() and use the returned values to limit the amount of data you read or write. + +For examples of the read/write I/O method see the following examples in the /tests directory of the PortAudio distribution: patest_read_record.c (audio input), patest_write_sine.c (audio output), patest_read_write_wire.c (audio pass-through). + +@subsection stream_info Retrieving Stream Information + +You can retrieve information about an open Stream by calling Pa_GetStreamInfo(). This returns a @ref PaStreamInfo structure containing the actual input and output latency and sample rate of the stream. It's possible for these values to be different from the suggested values passed to Pa_OpenStream(). + +When using a callback stream you can call Pa_GetStreamCpuLoad() to retrieve a rough estimate of the amount of CPU time your callback function is using. + +@subsection stream_timing Stream Timing Information + +When using the callback I/O method your stream callback function receives timing information via a pointer to a PaStreamCallbackTimeInfo structure. This structure contains the current time along with the estimated hardware capture and playback time of the first sample of the input and output buffers. All times are measured in seconds relative to a Stream-specific clock. The current Stream clock time can be retrieved using Pa_GetStreamTime(). + +You can use the stream callback @ref PaStreamCallbackTimeInfo times in conjunction with timestamps returned by Pa_GetStreamTime() to implement time synchronization schemes such as time aligning your GUI display with rendered audio, or maintaining synchronization between MIDI and audio playback. + +@section error_handling Error Handling + +Most PortAudio functions return error codes using values from the @ref PaError enumeration. All error codes are negative values. Some functions return values greater than or equal to zero for normal results and a negative error code in case of error. + +You can convert @ref PaError error codes to human readable text by calling Pa_GetErrorText(). + +PortAudio usually tries to translate error conditions into portable @ref PaError error codes. However if an unexpected error is encountered the @ref paUnanticipatedHostError code may be returned. In this case a further mechanism is provided to query for Host API-specific error information. If PortAudio returns @ref paUnanticipatedHostError you can call Pa_GetLastHostErrorInfo() to retrieve a pointer to a @ref PaHostErrorInfo structure that provides more information, including the Host API that encountered the error, a native API error code and error text. + +@section host_api_extensions Host API and Platform-specific Extensions + +The public PortAudio API only exposes functionality that can be provided across all target platforms. In some cases individual native audio APIs offer unique functionality. Some PortAudio Host APIs expose this functionality via Host API-specific extensions. Examples include access to low-level buffering and priority parameters, opening a Stream with only a subset of a Device's channels, or accessing channel metadata such as channel names. + +Host API-specific extensions are provided in the form of additional functions and data structures defined in Host API-specific header files found in the /include directory. + +The @ref PaStreamParameters structure passed to Pa_IsFormatSupported() and Pa_OpenStream() has a field named @ref PaStreamParameters::hostApiSpecificStreamInfo that is sometimes used to pass low level information when opening a Stream. + +See the documentation for the individual Host API-specific header files for details of the extended functionality they expose: + +- pa_asio.h +- pa_jack.h +- pa_linux_alsa.h +- pa_mac_core.h +- pa_win_ds.h +- pa_win_wasapi.h +- pa_win_wmme.h +- pa_win_waveformat.h + +*/ \ No newline at end of file diff --git a/extern/portaudio/doc/src/images/portaudio-external-architecture-diagram.png b/extern/portaudio/doc/src/images/portaudio-external-architecture-diagram.png new file mode 100644 index 0000000..64c0905 Binary files /dev/null and b/extern/portaudio/doc/src/images/portaudio-external-architecture-diagram.png differ diff --git a/extern/portaudio/doc/src/license.dox b/extern/portaudio/doc/src/license.dox new file mode 100644 index 0000000..8d0c51f --- /dev/null +++ b/extern/portaudio/doc/src/license.dox @@ -0,0 +1,38 @@ +/** @page License PortAudio License + +PortAudio Portable Real-Time Audio Library

The default described above is recommended as it is the most supported and tested; however, your needs may differ and require other options, which are described below. + +@subsection comp_mac_ca_3.1 Building Non-Universal Libraries + +By default, PortAudio is built as a universal binary. This includes 64-bit versions if you are compiling on 10.5, Leopard. If you want a "thin", or single architecture library, you have two options: + + * build a non-universal library using configure options. + * use lipo(1) on whatever part of the library you plan to use. + +Note that the first option may require an extremely recent version of PortAudio (February 5th '08 at least). + +@subsection comp_mac_ca_3.2 Building with --disable-mac-universal + +To build a non-universal library for the host architecture, simply use the --disable-mac-universal option with configure. + +@code + ./configure --disable-mac-universal && make +@endcode + +The --disable-mac-universal option may also be used in conjunction with environment variables to give you more control over the universal binary build process. For example, to build a universal binary for the i386 and ppc architectures using the 10.4u sdk (which is the default on 10.4, but not 10.5), you might specify this configure command line: + +@code + CFLAGS="-O2 -g -Wall -arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.3" \ + LDFLAGS="-arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.3" \ + ./configure --disable-mac-universal --disable-dependency-tracking +@endcode + +For more info, see Apple's documentation on the matter: + + * http://developer.apple.com/technotes/tn2005/tn2137.html + * http://developer.apple.com/documentation/Porting/Conceptual/PortingUnix/intro/chapter_1_section_1.html + +@subsection comp_mac_ca_3.3 Using lipo + +The second option is to build normally, and use lipo (1) to extract the architectures you want. For example, if you want a "thin", i386 library only: + +@code + lipo lib/.libs/libportaudio.a -thin i386 -output libportaudio.a +@endcode + +or if you want to extract a single architecture fat file: + +@code + lipo lib/.libs/libportaudio.a -extract i386 -output libportaudio.a +@endcode + +@subsection comp_mac_ca_3.4 Building With Debug Options + +By default, PortAudio on the mac is built without any debugging options. This is because asserts are generally inappropriate for a production environment and debugging information has been suspected, though not proven, to cause trouble with some interfaces. If you would like to compile with debugging, you must run configure with the appropriate flags. For example: + +@code + ./configure --enable-mac-debug && make +@endcode + +This will enable -g and disable -DNDEBUG which will effectively enable asserts. + +@section comp_mac_ca_4 Using the Library in XCode Projects + +If you are planning to follow the rest of the tutorial, several project types will work. You can create a "Standard Tool" under "Command Line Utility". If you are not following the rest of the tutorial, any type of project should work with PortAudio, but these instructions may not work perfectly. + +Once you've compiled PortAudio, the easiest and recommended way to use PortAudio in your XCode project is to add "/include/portaudio.h" and "/lib/.libs/libportaudio.a" to your project. Because "/lib/.libs/" is a hidden directory, you won't be able to navigate to it using the finder or the standard Mac OS file dialogs by clicking on files and folders. You can use command-shift-G in the finder to specify the exact path, or, from the shell, if you are in the portaudio directory, you can enter this command: + +@code + open lib/.libs +@endcode + +Then drag the "libportaudio.a" file into your XCode project and place it in the "External Frameworks and Libraries" group, if the project type has it.

Callback interface is implemented in + two versions: + + 1) Event-Driven: + This is the most powerful WASAPI implementation which provides glitch-free + audio at around 3ms latency in Exclusive mode. Lowest possible latency for this mode is + 3 ms for HD Audio class audio chips. For the Shared mode latency can not be + lower than 20 ms. + + 2) Poll-Driven: + Polling is another 2-nd method to operate with WASAPI. It is less efficient than Event-Driven + and provides latency at around 10-13ms. Polling must be used to overcome a system bug + under Windows Vista x64 when application is WOW64(32-bit) and Event-Driven method simply + times out (event handle is never signalled on buffer completion). Please note, such WOW64 bug + does not exist in Vista x86 or Windows 7. + Polling can be setup by speciying 'paWinWasapiPolling' flag. Our WASAPI implementation detects + WOW64 bug and sets 'paWinWasapiPolling' automatically. + + Thread priority: + + Normally thread priority is set automatically and does not require modification. Although + if user wants some tweaking thread priority can be modified by setting 'paWinWasapiThreadPriority' + flag and specifying 'PaWasapiStreamInfo::threadPriority' with value from PaWasapiThreadPriority + enum. + + Blocking Interface: + + Blocking interface is implemented but due to above described Poll-Driven method can not + deliver lowest possible latency. Specifying too low latency in Shared mode will result in + distorted audio although Exclusive mode adds stability. + + 8.24 format: + + If paCustomFormat is specified as sample format then the implementation will understand it + as valid 24-bits inside 32-bit container (e.g. wBitsPerSample = 32, Samples.wValidBitsPerSample = 24). + + By using paCustomFormat there will be small optimization when samples are be copied + with Copy_24_To_24 by PA processor instead of conversion from packed 3-byte (24-bit) data + with Int24_To_Int32. + + Pa_IsFormatSupported: + + To check format with correct Share Mode (Exclusive/Shared) you must supply PaWasapiStreamInfo + with flags paWinWasapiExclusive set through member of PaStreamParameters::hostApiSpecificStreamInfo + structure. + + If paWinWasapiExplicitSampleFormat flag is provided then implementation will not try to select + suitable close format and will return an error instead of paFormatIsSupported.

    +PortAudio - Portable Audio Library

    +
    + +

    PortAudio is a cross platform, open-source, audio +I/O library proposed by Ross Bencina to the music-dsp +mailing list. It lets you write simple audio programs in 'C' that will +compile and run on Windows, Macintosh, Unix, BeOS. PortAudio is +intended to promote the exchange of audio synthesis software between developers +on different platforms. +

    Overview

    + + The "Buffer Processor" (PaUtilBufferProcessor) manages conversion of audio + data from host buffers to user buffers and back again. Where required, the + buffer processor takes care of converting between host and user sample formats, + interleaving and deinterleaving multichannel buffers, and adapting between host + and user buffers with different lengths. The buffer processor may be used with + full and half duplex streams, for both callback streams and blocking read/write + streams. + + One of the important capabilities provided by the buffer processor is + the ability to adapt between user and host buffer sizes of different lengths + with minimum latency. Although this task is relatively easy to perform when + the host buffer size is an integer multiple of the user buffer size, the + problem is more complicated when this is not the case - especially for + full-duplex callback streams. Where necessary the adaption is implemented by + internally buffering some input and/or output data. The buffer adation + algorithm used by the buffer processor was originally implemented by + Stephan Letz for the ASIO version of PortAudio, and is described in his + Callback_adaption_.pdf which is included in the distribution. + + The buffer processor performs sample conversion using the functions provided + by pa_converters.c. + + The following sections provide an overview of how to use the buffer processor. + Interested readers are advised to consult the host API implementations for + examples of buffer processor usage. + + +

    Initialization, resetting and termination

    + + When a stream is opened, the buffer processor should be initialized using + PaUtil_InitializeBufferProcessor. This function initializes internal state + and allocates temporary buffers as neccesary according to the supplied + configuration parameters. Some of the parameters correspond to those requested + by the user in their call to Pa_OpenStream(), others reflect the requirements + of the host API implementation - they indicate host buffer sizes, formats, + and the type of buffering which the Host API uses. The buffer processor should + be initialized for callback streams and blocking read/write streams. + + Call PaUtil_ResetBufferProcessor to clear any sample data which is present + in the buffer processor before starting to use it (for example when + Pa_StartStream is called). + + When the buffer processor is no longer used call + PaUtil_TerminateBufferProcessor. + + +

    Using the buffer processor for a callback stream

    + + The buffer processor's role in a callback stream is to take host input buffers + process them with the stream callback, and fill host output buffers. For a + full duplex stream, the buffer processor handles input and output simultaneously + due to the requirements of the minimum-latency buffer adation algorithm. + + When a host buffer becomes available, the implementation should call + the buffer processor to process the buffer. The buffer processor calls the + stream callback to consume and/or produce audio data as necessary. The buffer + processor will convert sample formats, interleave/deinterleave channels, + and slice or chunk the data to the appropriate buffer lengths according to + the requirements of the stream callback and the host API. + + To process a host buffer (or a pair of host buffers for a full-duplex stream) + use the following calling sequence: + + -# Call PaUtil_BeginBufferProcessing + -# For a stream which takes input: + - Call PaUtil_SetInputFrameCount with the number of frames in the host input + buffer. + - Call one of the following functions one or more times to tell the + buffer processor about the host input buffer(s): PaUtil_SetInputChannel, + PaUtil_SetInterleavedInputChannels, PaUtil_SetNonInterleavedInputChannel. + Which function you call will depend on whether the host buffer(s) are + interleaved or not. + - If the available host data is split accross two buffers (for example a + data range at the end of a circular buffer and another range at the + beginning of the circular buffer), also call + PaUtil_Set2ndInputFrameCount, PaUtil_Set2ndInputChannel, + PaUtil_Set2ndInterleavedInputChannels, + PaUtil_Set2ndNonInterleavedInputChannel as necessary to tell the buffer + processor about the second buffer. + -# For a stream which generates output: + - Call PaUtil_SetOutputFrameCount with the number of frames in the host + output buffer. + - Call one of the following functions one or more times to tell the + buffer processor about the host output buffer(s): PaUtil_SetOutputChannel, + PaUtil_SetInterleavedOutputChannels, PaUtil_SetNonInterleavedOutputChannel. + Which function you call will depend on whether the host buffer(s) are + interleaved or not. + - If the available host output buffer space is split accross two buffers + (for example a data range at the end of a circular buffer and another + range at the beginning of the circular buffer), call + PaUtil_Set2ndOutputFrameCount, PaUtil_Set2ndOutputChannel, + PaUtil_Set2ndInterleavedOutputChannels, + PaUtil_Set2ndNonInterleavedOutputChannel as necessary to tell the buffer + processor about the second buffer. + -# Call PaUtil_EndBufferProcessing, this function performs the actual data + conversion and processing. + + +

    Using the buffer processor for a blocking read/write stream

    + + Blocking read/write streams use the buffer processor to convert and copy user + output data to a host buffer, and to convert and copy host input data to + the user's buffer. The buffer processor does not perform any buffer adaption. + When using the buffer processor in a blocking read/write stream the input and + output conversion are performed separately by the PaUtil_CopyInput and + PaUtil_CopyOutput functions. + + To copy data from a host input buffer to the buffer(s) which the user supplies + to Pa_ReadStream, use the following calling sequence. + + - Repeat the following three steps until the user buffer(s) have been filled + with samples from the host input buffers: + -# Call PaUtil_SetInputFrameCount with the number of frames in the host + input buffer. + -# Call one of the following functions one or more times to tell the + buffer processor about the host input buffer(s): PaUtil_SetInputChannel, + PaUtil_SetInterleavedInputChannels, PaUtil_SetNonInterleavedInputChannel. + Which function you call will depend on whether the host buffer(s) are + interleaved or not. + -# Call PaUtil_CopyInput with the user buffer pointer (or a copy of the + array of buffer pointers for a non-interleaved stream) passed to + Pa_ReadStream, along with the number of frames in the user buffer(s). + Be careful to pass a copy of the user buffer pointers to + PaUtil_CopyInput because PaUtil_CopyInput advances the pointers to + the start of the next region to copy. + - PaUtil_CopyInput will not copy more data than is available in the + host buffer(s), so the above steps need to be repeated until the user + buffer(s) are full. + + + To copy data to the host output buffer from the user buffers(s) supplied + to Pa_WriteStream use the following calling sequence. + + - Repeat the following three steps until all frames from the user buffer(s) + have been copied to the host API: + -# Call PaUtil_SetOutputFrameCount with the number of frames in the host + output buffer. + -# Call one of the following functions one or more times to tell the + buffer processor about the host output buffer(s): PaUtil_SetOutputChannel, + PaUtil_SetInterleavedOutputChannels, PaUtil_SetNonInterleavedOutputChannel. + Which function you call will depend on whether the host buffer(s) are + interleaved or not. + -# Call PaUtil_CopyOutput with the user buffer pointer (or a copy of the + array of buffer pointers for a non-interleaved stream) passed to + Pa_WriteStream, along with the number of frames in the user buffer(s). + Be careful to pass a copy of the user buffer pointers to + PaUtil_CopyOutput because PaUtil_CopyOutput advances the pointers to + the start of the next region to copy. + - PaUtil_CopyOutput will not copy more data than fits in the host buffer(s), + so the above steps need to be repeated until all user data is copied. +*/ + + +#include "portaudio.h" +#include "pa_converters.h" +#include "pa_dither.h" + +#ifdef __cplusplus +extern "C" +{ +#endif /* __cplusplus */ + + +/** @brief Mode flag passed to PaUtil_InitializeBufferProcessor indicating the type + of buffering that the host API uses. + + The mode used depends on whether the host API or the implementation manages + the buffers, and how these buffers are used (scatter gather, circular buffer). +*/ +typedef enum { +/** The host buffer size is a fixed known size. */ + paUtilFixedHostBufferSize, + +/** The host buffer size may vary, but has a known maximum size. */ + paUtilBoundedHostBufferSize, + +/** Nothing is known about the host buffer size. */ + paUtilUnknownHostBufferSize, + +/** The host buffer size varies, and the client does not require the buffer + processor to consume all of the input and fill all of the output buffer.

    Overview

    + + This is a PortAudio implementation for the AudioScience HPI Audio API + on the Linux platform. AudioScience makes a range of audio adapters customised + for the broadcasting industry, with support for both Windows and Linux. + More information on their products can be found on their website: + + http://www.audioscience.com + + Documentation for the HPI API can be found at: + + http://www.audioscience.com/internet/download/sdk/hpi_usermanual_html/html/index.html + + The Linux HPI driver itself (a kernel module + library) can be downloaded from: + + http://www.audioscience.com/internet/download/linux_drivers.htm + +

    Implementation strategy

    + + *Note* Ideally, AudioScience cards should be handled by the PortAudio ALSA + implementation on Linux, as ALSA is the preferred Linux soundcard API. The existence + of this host API implementation might therefore seem a bit flawed. Unfortunately, at + the time of the creation of this implementation (June 2006), the PA ALSA implementation + could not make use of the existing AudioScience ALSA driver. PA ALSA uses the + "memory-mapped" (mmap) ALSA access mode to interact with the ALSA library, while the + AudioScience ALSA driver only supports the "read-write" access mode. The appropriate + solution to this problem is to add "read-write" support to PortAudio ALSA, thereby + extending the range of soundcards it supports (AudioScience cards are not the only + ones with this problem). Given the author's limited knowledge of ALSA and the + simplicity of the HPI API, the second-best solution was born... + + The following mapping between HPI and PA was followed: + HPI subsystem => PortAudio host API + HPI adapter => nothing specific + HPI stream => PortAudio device + + Each HPI stream is either input or output (not both), and can support + different channel counts, sampling rates and sample formats. It is therefore + a more natural fit to a PA device. A PA stream can therefore combine two + HPI streams (one input and one output) into a "full-duplex" stream. These + HPI streams can even be on different physical adapters. The two streams ought to be + sample-synchronised when they reside on the same adapter, as most AudioScience adapters + derive their ADC and DAC clocks from one master clock. When combining two adapters + into one full-duplex stream, however, the use of a word clock connection between the + adapters is strongly recommended. + + The HPI interface is inherently blocking, making use of read and write calls to + transfer data between user buffers and driver buffers. The callback interface therefore + requires a helper thread ("callback engine") which periodically transfers data (one thread + per PA stream, in fact). The current implementation explicitly sleeps via Pa_Sleep() until + enough samples can be transferred (select() or poll() would be better, but currently seems + impossible...). The thread implementation makes use of the Unix thread helper functions + and some pthread calls here and there. If a unified PA thread exists, this host API + implementation might also compile on Windows, as this is the only real Linux-specific + part of the code. + + There is no inherent fixed buffer size in the HPI interface, as in some other host APIs. + The PortAudio implementation contains a buffer that is allocated during OpenStream and + used to transfer data between the callback and the HPI driver buffer. The size of this + buffer is quite flexible and is derived from latency suggestions and matched to the + requested callback buffer size as far as possible. It can become quite huge, as the + AudioScience cards are typically geared towards higher-latency applications and contain + large hardware buffers. + + The HPI interface natively supports most common sample formats and sample rates (some + conversion is done on the adapter itself). + + Stream time is measured based on the number of processed frames, which is adjusted by the + number of frames currently buffered by the HPI driver. + + There is basic support for detecting overflow and underflow. The HPI interface does not + explicitly indicate this, so thresholds on buffer levels are used in combination with + stream state. Recovery from overflow and underflow is left to the PA client. + + Blocking streams are also implemented. It makes use of the same polling routines that + the callback interface uses, in order to prevent the allocation of variable-sized + buffers during reading and writing. The framesPerBuffer parameter is therefore still + relevant, and this can be increased in the blocking case to improve efficiency. + + The implementation contains extensive reporting macros (slightly modified PA_ENSURE and + PA_UNLESS versions) and a useful stream dump routine to provide debugging feedback. + + Output buffer priming via the user callback (i.e. paPrimeOutputBuffersUsingStreamCallback + and friends) is not implemented yet.

This causes MSVC++ to default + to using the thiscall convention, which is a proprietary convention not + implemented by some non-microsoft compilers - notably borland BCC, + C++Builder, and gcc.

As a result of this situation, the ASIO sdk will compile with + any compiler, however attempting to execute the compiled code will cause a + crash due to different default calling conventions on non-Microsoft + compilers. + + IASIOThiscallResolver solves the problem by providing an adapter class that + delegates to the IASIO interface using the correct calling convention + (thiscall). Due to the lack of support for thiscall in the Borland and GCC + compilers, the calls have been implemented in assembly language. + + A number of macros are defined for thiscall function calls with different + numbers of parameters, with and without return values - it may be possible + to modify the format of these macros to make them work with other inline + assemblers. + + + THISCALL DEFINITION + + A number of definitions of the thiscall calling convention are floating + around the internet. The following definition has been validated against + output from the MSVC++ compiler: + + For non-vararg functions, thiscall works as follows: the object (this) + pointer is passed in ECX. All arguments are passed on the stack in + right to left order. The return value is placed in EAX. The callee + clears the passed arguments from the stack. + + + FINDING FUNCTION POINTERS FROM AN IASIO POINTER + + The first field of a COM object is a pointer to its vtble. Thus a pointer + to an object implementing the IASIO interface also points to a pointer to + that object's vtbl.

To select use the old implementation, replace +pa_mac_core.c with pa_mac_core_old.c (eg. "cp pa_mac_core_auhal.c +pa_mac_core.c"), then run configure and make as usual. + +------------------------------------------- + +Notes on Newer/Default AUHAL implementation: + +by Bjorn Roche + +Last Updated December 9, 2005 + +Principle of Operation: + +This implementation uses AUHAL for audio I/O. To some extent, it also +operates at the "HAL" Layer, though this behavior can be limited by +platform specific flags (see pa_mac_core.h for details). The default +settings should be reasonable: they don't change the SR of the device and +don't cause interruptions if other devices are using the device. + +Major Software Elements Used: Apple's HAL AUs provide output SR +conversion transparently, however, only on output, so this +implementation uses AudioConverters to convert the sample rate on input. +A PortAudio ring buffer is used to buffer input when sample rate +conversion is required or when separate audio units are used for duplex +IO. Finally, a PortAudio buffer processor is used to convert formats and +provide additional buffers if needed. Internally, interleaved floating +point data streams are used exclusively - the audio unit converts from +the audio hardware's native format to interleaved float PCM and +PortAudio's Buffer processor is used for conversion to user formats. + +Simplex Input: Simplex input uses a single callback. If sample rate +conversion is required, a ring buffer and AudioConverter are used as +well. + +Simplex output: Simplex output uses a single callback. No ring buffer or +audio converter is used because AUHAL does its own output SR conversion. + +Duplex, one device (no SR conversion): When one device is used, a single +callback is used. This achieves very low latency. + +Duplex, separate devices or SR conversion: When SR conversion is +required, data must be buffered before it is converted and data is not +always available at the same times on input and output, so SR conversion +requires the same treatment as separate devices. The input callback +reads data and puts it in the ring buffer. The output callback reads the +data off the ring buffer, into an audio converter and finally to the +buffer processor. + +Platform Specific Options: + +By using the flags in pa_mac_core.h, the user may specify several options. +For example, the user can specify the sample-rate conversion quality, and +the extent to which PA will attempt to "play nice" and to what extent it +will interrupt other apps to improve performance. For example, if 44100 Hz +sample rate is requested but the device is set at 48000 Hz, PA can either +change the device for optimal playback ("Pro" mode), which may interrupt +other programs playing back audio, or simple use a sample-rate coversion, +which allows for friendlier sharing of the device ("Play Nice" mode). + +Additionally, the user may define a "channel mapping" by calling +paSetupMacCoreChannelMap() on their stream info structure before opening +the stream with it. See below for creating a channel map. + +Known issues: + +- Buffering: No buffering beyond that provided by core audio is provided +except where absolutely needed for the implementation to work. This may cause +issues with large framesPerBuffer settings and it also means that no additional +latency will be provided even if a large latency setting is selected. + +- Latency: Latency settings are generally ignored. They may be used as a +hint for buffer size in paHostFramesPerBufferUnspecified, or the value may +be used in cases where additional buffering is needed, such as doing input and +output on seperate devices. Latency settings are always automatically bound +to "safe" values, however, so setting extreme values here should not be +an issue. + +- Buffer Size: paHostFramesPerBufferUnspecified and specific host buffer sizes +are supported. paHostFramesPerBufferUnspecified works best in "pro" mode, +where the buffer size and sample rate of the audio device is most likely +to match the expected values. In the case of paHostFramesPerBuffer, an +appropriate framesPerBuffer value will be used that guarantees minimum +requested latency if that's possible. + +- Timing info. It reports on stream time, but I'm probably doing something +wrong since patest_sine_time often reports negative latency numbers. Also, +there are currently issues with some devices whehn plugging/unplugging +devices. + +- xrun detection: The only xrun detection performed is when reading +and writing the ring buffer. There is probably more that can be done. + +- abort/stop issues: stopping a stream is always a complete operation, +but latency should be low enough to make the lack of a separate abort +unnecessary. Apple clarifies its AudioOutputUnitStop() call here: +http://lists.apple.com/archives/coreaudio-api/2005/Dec/msg00055.html + +- blocking interface: should work fine. + +- multichannel: It has been tested successfully on multichannel hardware +from MOTU: traveler and 896HD. Also Presonus firepod and others. It is +believed to work with all Core Audio devices, including virtual devices +such as soundflower. + +- sample rate conversion quality: By default, SR conversion is the maximum +available. This can be tweaked using flags pa_mac_core.h. Note that the AU +render quyality property is used to set the sample rate conversion quality +as "documented" here: +http://lists.apple.com/archives/coreaudio-api/2004/Jan/msg00141.html + +- x86/Universal Binary: Universal binaries can be build. + + + +Creating a channel map: + +How to create the map array - Text taken From AUHAL.rtfd : +[3] Channel Maps +Clients can tell the AUHAL units which channels of the device they are interested in. For example, the client may be processing stereo data, but outputting to a six-channel device. This is done by using the kAudioOutputUnitProperty_ChannelMap property. To use this property: + +For Output: +Create an array of SInt32 that is the size of the number of channels of the device (Get the Format of the AUHAL's output Element == 0) +Initialize each of the array's values to -1 (-1 indicates that that channel is NOT to be presented in the conversion.) + +Next, for each channel of your app's output, set: +channelMapArray[deviceOutputChannel] = desiredAppOutputChannel. + +For example: we have a 6 channel output device and our application has a stereo source it wants to provide to the device. Suppose we want that stereo source to go to the 3rd and 4th channels of the device. The channel map would look like this: { -1, -1, 0, 1, -1, -1 } + +Where the formats are: +Input Element == 0: 2 channels (- client format - settable) +Output Element == 0: 6 channels (- device format - NOT settable) + +So channel 2 (zero-based) of the device will take the first channel of output and channel 3 will take the second channel of output. (This translates to the 3rd and 4th plugs of the 6 output plugs of the device of course!) + +For Input: +Create an array of SInt32 that is the size of the number of channels of the format you require for input. Get (or Set in this case as needed) the AUHAL's output Element == 1. + +Next, for each channel of input you require, set: +channelMapArray[desiredAppInputChannel] = deviceOutputChannel; + +For example: we have a 6 channel input device from which we wish to receive stereo input from the 3rd and 4th channels. The channel map looks like this: { 2, 3 } + +Where the formats are: +Input Element == 0: 2 channels (- device format - NOT settable) +Output Element == 0: 6 channels (- client format - settable) + + + +---------------------------------------- + +Notes on Original implementation: + +by Phil Burk and Darren Gibbs + +Last updated March 20, 2002 + +WHAT WORKS + +Output with very low latency, <10 msec. +Half duplex input or output. +Full duplex on the same CoreAudio device. +The paFLoat32, paInt16, paInt8, paUInt8 sample formats. +Pa_GetCPULoad() +Pa_StreamTime() + +KNOWN BUGS OR LIMITATIONS + +We do not yet support simultaneous input and output on different +devices.

But the sample +rates supported may be different. So we have map one or two PortAudio +device to each CoreAudio device depending on whether it supports +input, output or both. + +When we query devices, we first get a list of CoreAudio devices. Then +we scan the list and add a PortAudio device for each CoreAudio device +that supports input. Then we make a scan for output devices. + diff --git a/extern/portaudio/src/hostapi/coreaudio/pa_mac_core.c b/extern/portaudio/src/hostapi/coreaudio/pa_mac_core.c new file mode 100644 index 0000000..257e9de --- /dev/null +++ b/extern/portaudio/src/hostapi/coreaudio/pa_mac_core.c @@ -0,0 +1,2836 @@ +/* + * Implementation of the PortAudio API for Apple AUHAL + * + * PortAudio Portable Real-Time Audio Library + * Latest Version at: http://www.portaudio.com + * + * Written by Bjorn Roche of XO Audio LLC, from PA skeleton code. + * Portions copied from code by Dominic Mazzoni (who wrote a HAL implementation) + * + * Dominic's code was based on code by Phil Burk, Darren Gibbs, + * Gord Peters, Stephane Letz, and Greg Pfiel. + * + * The following people also deserve acknowledgements: + * + * Olivier Tristan for feedback and testing + * Glenn Zelniker and Z-Systems engineering for sponsoring the Blocking I/O + * interface. + * + * + * Based on the Open Source API proposed by Ross Bencina + * Copyright (c) 1999-2002 Ross Bencina, Phil Burk + * + * Permission is hereby granted, free of charge, to any person obtaining + * a copy of this software and associated documentation files + * (the "Software"), to deal in the Software without restriction, + * including without limitation the rights to use, copy, modify, merge, + * publish, distribute, sublicense, and/or sell copies of the Software, + * and to permit persons to whom the Software is furnished to do so, + * subject to the following conditions: + * + * The above copyright notice and this permission notice shall be + * included in all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, + * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. + * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR + * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF + * CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION + * WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + */ + +/* + * The text above constitutes the entire PortAudio license; however, + * the PortAudio community also makes the following non-binding requests: + * + * Any person wishing to distribute modifications to the Software is + * requested to send the modifications to the original developer so that + * they can be incorporated into the canonical version.

It should be considered +an alpha release with zero guarantee not to crash on any particular +system. So far it has only been tested in the author's development +environment, which means a Win2k/SP2 PIII laptop with integrated +SoundMAX driver and USB Tascam US-428 compiled with both MinGW +(GCC 3.3) and MSVC++6 using the MS DirectX 9 SDK. +It has been most widely tested with the MinGW build, with most of the +test programs (particularly paqa_devs and paqa_errs) passing. +There are some notable failures: patest_out_underflow and both of the +blocking I/O tests (as blocking I/O is not implemented). +At this point the code needs to be tested with a much wider variety +of configurations and feedback provided from testers regarding +both working and failing cases. + +What is the WDM-KS host API? +---------------------------- +PortAudio for Windows currently has 3 functional host implementations. +MME uses the oldest Windows audio API which does not offer good +play/record latency. +DirectX improves this, but still imposes a penalty +of 10s of milliseconds due to the system mixing of streams from +multiple applications. +ASIO offers very good latency, but requires special drivers which are +not always available for cheaper audio hardware. Also, when ASIO +drivers are available, they are not always so robust because they +bypass all of the standardised Windows device driver architecture +and hit the hardware their own way. +Alternatively there are a couple of free (but closed source) ASIO +implementations which connect to the lower level Windows +"Kernel Streaming" API, but again these require special installation +by the user, and can be limited in functionality or difficult to use. + +This is where the PortAudio "WDM-KS" host implementation comes in. +It directly connects PortAudio to the same Kernel Streaming API which +those ASIO bridges use. This avoids the mixing penatly of DirectX, +giving at least as good latency as any ASIO driver, but it has the +advantage of working with ANY Windows audio hardware which is available +through the normal MME/DirectX routes without the user requiring +any additional device drivers to be installed, and allowing all +device selection to be done through the normal PortAudio API. + +Note that in general you should only be using this host API if your +application has a real requirement for very low latency audio (<20ms), +either because you are generating sounds in real-time based upon +user input, or you a processing recorded audio in real time. + +The only thing to be aware of is that using the KS interface will +block that device from being used by the rest of system through +the higher level APIs, or conversely, if the system is using +a device, the KS API will not be able to use it. MS recommend that +you should keep the device open only when your application has focus. +In PortAudio terms, this means having a stream Open on a WDMKS device. + +Usage +----- +To add the WDMKS backend to your program which is already using +PortAudio, you must define PA_USE_WDMKS=1 in your build file, +and include the pa_win_wdmks\pa_win_wdmks.c into your build. +The file should compile in both C and C++. +You will need a DirectX SDK installed on your system for the +ks.h and ksmedia.h header files. +You will need to link to the system "setupapi" library. +Note that if you use MinGW, you will get more warnings from +the DX header files when using GCC(C), and still a few warnings +with G++(CPP). diff --git a/extern/portaudio/src/hostapi/wmme/pa_win_wmme.c b/extern/portaudio/src/hostapi/wmme/pa_win_wmme.c new file mode 100644 index 0000000..422c867 --- /dev/null +++ b/extern/portaudio/src/hostapi/wmme/pa_win_wmme.c @@ -0,0 +1,4055 @@ +/* + * $Id$ + * pa_win_wmme.c + * Implementation of PortAudio for Windows MultiMedia Extensions (WMME) + * + * PortAudio Portable Real-Time Audio Library + * Latest Version at: http://www.portaudio.com + * + * Authors: Ross Bencina and Phil Burk + * Copyright (c) 1999-2000 Ross Bencina and Phil Burk + * + * Permission is hereby granted, free of charge, to any person obtaining + * a copy of this software and associated documentation files + * (the "Software"), to deal in the Software without restriction, + * including without limitation the rights to use, copy, modify, merge, + * publish, distribute, sublicense, and/or sell copies of the Software, + * and to permit persons to whom the Software is furnished to do so, + * subject to the following conditions: + * + * The above copyright notice and this permission notice shall be + * included in all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, + * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. + * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR + * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF + * CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION + * WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + */ + +/* + * The text above constitutes the entire PortAudio license; however, + * the PortAudio community also makes the following non-binding requests: + * + * Any person wishing to distribute modifications to the Software is + * requested to send the modifications to the original developer so that + * they can be incorporated into the canonical version.
