In addition, it fixes a decoder bug (first introduced in + Duclair) so all users of that release are encouraged to upgrade. + + - Upgrading: + This release is ABI and API compatible with Duclair (v1.0.0). Users + of older releases should refer to the Upgrading notes in this + document for that release. + + This release introduces a new temporal denoiser, controlled by the + VP8E_SET_NOISE_SENSITIVITY control. The temporal denoiser does not + currently take a strength parameter, so the control is effectively + a boolean - zero (off) or non-zero (on). For compatibility with + existing applications, the values accepted are the same as those + for the spatial denoiser (0-6). The temporal denoiser is enabled + by default, and the older spatial denoiser may be restored by + configuring with --disable-temporal-denoising. The temporal denoiser + is more computationally intensive than the spatial one. + + This release removes support for a legacy, decode only API that was + supported, but deprecated, at the initial release of libvpx + (v0.9.0). This is not expected to have any impact. If you are + impacted, you can apply a reversion to commit 2bf8fb58 locally. + Please update to the latest libvpx API if you are affected. + + - Enhancements: + Adds a motion compensated temporal denoiser to the encoder, which + gives higher quality than the older spatial denoiser. (See above + for notes on upgrading). + + In addition, support for new compilers and platforms were added, + including: + improved support for XCode + Android x86 NDK build + OS/2 support + SunCC support + + Changing resolution with vpx_codec_enc_config_set() is now + supported. Previously, reinitializing the codec was required to + change the input resolution. + + The vpxenc application has initial support for producing multiple + encodes from the same input in one call. Resizing is not yet + supported, but varying other codec parameters is. Use -- to + delineate output streams. Options persist from one stream to the + next. + + Also, the vpxenc application will now use a keyframe interval of + 5 seconds by default. Use the --kf-max-dist option to override. + + - Speed: + Decoder performance improved 2.5% versus Duclair. Encoder speed is + consistent with Duclair for most material. Two pass encoding of + slideshow-like material will see significant improvements. + + Large realtime encoding speed gains at a small quality expense are + possible by configuring the on-the-fly bitpacking experiment with + --enable-onthefly-bitpacking. Realtime encoder can be up to 13% + faster (ARM) depending on the number of threads and bitrate + settings. This technique sees constant gain over the 5-16 speed + range. For VC style input the loss seen is up to 0.2dB. See commit + 52cf4dca for further details. + + - Quality: + On the whole, quality is consistent with the Duclair release. Some + tweaks: + + Reduced blockiness in easy sections by applying a penalty to + intra modes. + + Improved quality of static sections (like slideshows) with + two pass encoding. + + Improved keyframe sizing with multiple temporal layers + + - Bug Fixes: + Corrected alt-ref contribution to frame rate for visible updates + to the alt-ref buffer. This affected applications making manual + usage of the frame reference flags, or temporal layers. + + Additional constraints were added to disable multi-frame quality + enhancement (MFQE) in sections of the frame where there is motion. + (#392) + + Fixed corruption issues when vpx_codec_enc_config_set() was called + with spatial resampling enabled. + + Fixed a decoder error introduced in Duclair where the segmentation + map was not being reinitialized on keyframes (#378) + + +2012-01-27 v1.0.0 "Duclair" + Our fourth named release, focused on performance and features related to + real-time encoding. It also fixes a decoder crash bug introduced in + v0.9.7, so all users of that release are encouraged to upgrade. + + - Upgrading: + This release is ABI incompatible with prior releases of libvpx, so the + "major" version number has been bumped to 1. You must recompile your + applications against the latest version of the libvpx headers. The + API remains compatible, and this should not require code changes in most + applications. + + - Enhancements: + This release introduces several substantial new features to the encoder, + of particular interest to real time streaming applications. + + Temporal scalability allows the encoder to produce a stream that can + be decimated to different frame rates, with independent rate targetting + for each substream. + + Multiframe quality enhancement postprocessing can make visual quality + more consistent in the presence of frames that are substantially + different quality than the surrounding frames, as in the temporal + scalability case and in some forced keyframe scenarios. + + Multiple-resolution encoding support allows the encoding of the + same content at different resolutions faster than encoding them + separately. + + - Speed: + Optimization targets for this release included the decoder and the real- + time modes of the encoder. Decoder speed on x86 has improved 10.5% with + this release. Encoder improvements followed a curve where speeds 1-3 + improved 4.0%-1.5%, speeds 4-8 improved <1%, and speeds 9-16 improved + 1.5% to 10.5%, respectively. "Best" mode speed is consistent with the + Cayuga release. + + - Quality: + Encoder quality in the single stream case is consistent with the Cayuga + release. + + - Bug Fixes: + This release fixes an OOB read decoder crash bug present in v0.9.7 + related to the clamping of motion vectors in SPLITMV blocks.

All users of that + release are strongly encouraged to upgrade. + + - Fix potential OOB reads (cdae03a) + + An unbounded out of bounds read was discovered when the + decoder was requested to perform error concealment (new in + Cayuga) given a frame with corrupt partition sizes. + + A bounded out of bounds read was discovered affecting all + versions of libvpx. Given an multipartition input frame that + is truncated between the mode/mv partition and the first + residiual paritition (in the block of partition offsets), up + to 3 extra bytes could have been read from the source buffer. + The code will not take any action regardless of the contents + of these undefined bytes, as the truncated buffer is detected + immediately following the read based on the calculated + starting position of the coefficient partition. + + - Fix potential error concealment crash when the very first frame + is missing or corrupt (a609be5) + + - Fix significant artifacts in error concealment (a4c2211, 99d870a) + + - Revert 1-pass CBR rate control changes (e961317) + Further testing showed this change produced undesirable visual + artifacts, rolling back for now. + + +2011-08-02 v0.9.7 "Cayuga" + Our third named release, focused on a faster, higher quality, encoder. + + - Upgrading: + This release is backwards compatible with Aylesbury (v0.9.5) and + Bali (v0.9.6).

Other POSIX toolchains + will likely work as well. For instance, to build using the mipsel-linux-uclibc + toolchain, the following command could be used (note, POSIX SH syntax, adapt + to your shell as necessary): + + $ CROSS=mipsel-linux-uclibc- ../libvpx/configure + + In addition, the executables to be invoked can be overridden by specifying the + environment variables: CC, AR, LD, AS, STRIP, NM. Additional flags can be + passed to these executables with CFLAGS, LDFLAGS, and ASFLAGS. + + 5. Configuration errors + If the configuration step fails, the first step is to look in the error log. + This defaults to config.log. This should give a good indication of what went + wrong. If not, contact us for support. + +VP8/VP9 TEST VECTORS: + The test vectors can be downloaded and verified using the build system after + running configure. To specify an alternate directory the + LIBVPX_TEST_DATA_PATH environment variable can be used. + + $ ./configure --enable-unit-tests + $ LIBVPX_TEST_DATA_PATH=../libvpx-test-data make testdata + +SUPPORT + This library is an open source project supported by its community.

This is done by passing the VPX_CODEC_USE_POSTPROC +// flag to `vpx_codec_dec_init`. If the codec does not support +// postprocessing, this call will return VPX_CODEC_INCAPABLE. For +// demonstration purposes, we also fall back to default initialization if +// the codec does not provide support. +// +// Using Adaptive Postprocessing +// ----------------------------- +// VP6 provides "adaptive postprocessing." It will automatically select the +// best postprocessing filter on a frame by frame basis based on the amount +// of time remaining before the user's specified deadline expires. The +// special value 0 indicates that the codec should take as long as +// necessary to provide the best quality frame. This example gives the +// codec 15ms (15000us) to return a frame. Remember that this is a soft +// deadline, and the codec may exceed it doing its regular processing.

In this case, we're using +// vp8. +// +// Getting The Default Configuration +// --------------------------------- +// Encoders have the notion of "usage profiles." For example, an encoder +// may want to publish default configurations for both a video +// conferencing application and a best quality offline encoder. These +// obviously have very different default settings. Consult the +// documentation for your codec to see if it provides any default +// configurations. All codecs provide a default configuration, number 0, +// which is valid for material in the vacinity of QCIF/QVGA. +// +// Updating The Configuration +// --------------------------------- +// Almost all applications will want to update the default configuration +// with settings specific to their usage.

If a frame was read (the input file has not hit +// EOF) then the frame is passed to the encoder. Otherwise, a NULL +// is passed, indicating the End-Of-Stream condition to the encoder. The +// `frame_cnt` is reused as the presentation time stamp (PTS) and each +// frame is shown for one frame-time in duration. The flags parameter is +// unused in this example. The deadline is set to VPX_DL_REALTIME to +// make the example run as quickly as possible. + +// Forced Keyframes +// ---------------- +// Keyframes can be forced by setting the VPX_EFLAG_FORCE_KF bit of the +// flags passed to `vpx_codec_control()`. In this example, we force a +// keyframe every frames. Note, the output stream can +// contain additional keyframes beyond those that have been forced using the +// VPX_EFLAG_FORCE_KF flag because of automatic keyframe placement by the +// encoder. +// +// Processing The Encoded Data +// --------------------------- +// Each packet of type `VPX_CODEC_CX_FRAME_PKT` contains the encoded data +// for this frame.

has exited + prematurely and report it as a failure (before it would be + falsely reported as a success if the exit code is 0). +* New feature: Test::RecordProperty() can now be used outside of the + lifespan of a test method, in which case it will be attributed to + the current test case or the test program in the XML report. +* New feature (potentially breaking): --gtest_list_tests now prints + the type parameters and value parameters for each test. +* Improvement: char pointers and char arrays are now escaped properly + in failure messages. +* Improvement: failure summary in XML reports now includes file and + line information. +* Improvement: the XML element now has a timestamp attribute. +* Improvement: When --gtest_filter is specified, XML report now doesn't + contain information

Based on the +xUnit architecture. Supports automatic test discovery, a rich set of +assertions, user-defined assertions, death tests, fatal and non-fatal +failures, various options for running the tests, and XML test report +generation. + +Please see the project page above for more information as well as the +mailing list for questions, discussions, and development. There is +also an IRC channel on OFTC (irc.oftc.net) #gtest available. Please +join us! + +Requirements for End Users +-------------------------- + +Google Test is designed to have fairly minimal requirements to build +and use with your projects, but there are some. Currently, we support +Linux, Windows, Mac OS X, and Cygwin. We will also make our best +effort to support other platforms (e.g. Solaris, AIX, and z/OS). +However, since core members of the Google Test project have no access +to these platforms, Google Test may have outstanding issues there. If +you notice any problems on your platform, please notify +googletestframework@googlegroups.com. Patches for fixing them are +even more welcome! + +### Linux Requirements ### + +These are the base requirements to build and use Google Test from a source +package (as described below): + * GNU-compatible Make or gmake + * POSIX-standard shell + * POSIX(-2) Regular Expressions (regex.h) + * A C++98-standard-compliant compiler + +### Windows Requirements ### + + * Microsoft Visual C++ 7.1 or newer + +### Cygwin Requirements ### + + * Cygwin 1.5.25-14 or newer + +### Mac OS X Requirements ### + + * Mac OS X 10.4 Tiger or newer + * Developer Tools Installed + +Also, you'll need CMake 2.6.4 or higher if you want to build the +samples using the provided CMake script, regardless of the platform. + +Requirements for Contributors +----------------------------- + +We welcome patches. If you plan to contribute a patch, you need to +build Google Test and its own tests from an SVN checkout (described +below), which has further requirements: + + * Python version 2.3 or newer (for running some of the tests and + re-generating certain source files from templates) + * CMake 2.6.4 or newer + +Getting the Source +------------------ + +There are two primary ways of getting Google Test's source code: you +can download a stable source release in your preferred archive format, +or directly check out the source from our Subversion (SVN) repositary. +The SVN checkout requires a few extra steps and some extra software +packages on your system, but lets you track the latest development and +make patches much more easily, so we highly encourage it. + +### Source Package ### + +Google Test is released in versioned source packages which can be +downloaded from the download page [1]. Several different archive +formats are provided, but the only difference is the tools used to +manipulate them, and the size of the resulting file. Download +whichever you are most comfortable with. + + [1] http://code.google.com/p/googletest/downloads/list + +Once the package is downloaded, expand it using whichever tools you +prefer for that type. This will result in a new directory with the +name "gtest-X.Y.Z" which contains all of the source code. Here are +some examples on Linux: + + tar -xvzf gtest-X.Y.Z.tar.gz + tar -xvjf gtest-X.Y.Z.tar.bz2 + unzip gtest-X.Y.Z.zip + +### SVN Checkout ### + +To check out the main branch (also known as the "trunk") of Google +Test, run the following Subversion command: + + svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn + +Setting up the Build +-------------------- + +To build Google Test and your tests that use it, you need to tell your +build system where to find its headers and source files. The exact +way to do it depends on which build system you use, and is usually +straightforward. + +### Generic Build Instructions ### + +Suppose you put Google Test in directory ${GTEST_DIR}. To build it, +create a library build target (or a project as called by Visual Studio +and Xcode) to compile + + ${GTEST_DIR}/src/gtest-all.cc + +with ${GTEST_DIR}/include in the system header search path and ${GTEST_DIR} +in the normal header search path. Assuming a Linux-like system and gcc, +something like the following will do: + + g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \ + -pthread -c ${GTEST_DIR}/src/gtest-all.cc + ar -rv libgtest.a gtest-all.o + +(We need -pthread as Google Test uses threads.) + +Next, you should compile your test source file with +${GTEST_DIR}/include in the system header search path, and link it +with gtest and any other necessary libraries: + + g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \ + -o your_test + +As an example, the make/ directory contains a Makefile that you can +use to build Google Test on systems where GNU make is available +(e.g. Linux, Mac OS X, and Cygwin). It doesn't try to build Google +Test's own tests. Instead, it just builds the Google Test library and +a sample test. You can use it as a starting point for your own build +script. + +If the default settings are correct for your environment, the +following commands should succeed: + + cd ${GTEST_DIR}/make + make + ./sample1_unittest + +If you see errors, try to tweak the contents of make/Makefile to make +them go away. There are instructions in make/Makefile on how to do +it. + +### Using CMake ### + +Google Test comes with a CMake build script (CMakeLists.txt) that can +be used on a wide range of platforms ("C" stands for cross-platofrm.). +If you don't have CMake installed already, you can download it for +free from http://www.cmake.org/. + +CMake works by generating native makefiles or build projects that can +be used in the compiler environment of your choice. The typical +workflow starts with: + + mkdir mybuild # Create a directory to hold the build output. + cd mybuild + cmake ${GTEST_DIR} # Generate native build scripts. + +If you want to build Google Test's samples, you should replace the +last command with + + cmake -Dgtest_build_samples=ON ${GTEST_DIR} + +If you are on a *nix system, you should now see a Makefile in the +current directory. Just type 'make' to build gtest. + +If you use Windows and have Vistual Studio installed, a gtest.sln file +and several .vcproj files will be created. You can then build them +using Visual Studio. + +On Mac OS X with Xcode installed, a .xcodeproj file will be generated. + +### Legacy Build Scripts ### + +Before settling on CMake, we have been providing hand-maintained build +projects/scripts for Visual Studio, Xcode, and Autotools. While we +continue to provide them for convenience, they are not actively +maintained any more. We highly recommend that you follow the +instructions in the previous two sections to integrate Google Test +with your existing build system. + +If you still need to use the legacy build scripts, here's how: + +The msvc\ folder contains two solutions with Visual C++ projects. +Open the gtest.sln or gtest-md.sln file using Visual Studio, and you +are ready to build Google Test the same way you build any Visual +Studio project. Files that have names ending with -md use DLL +versions of Microsoft runtime libraries (the /MD or the /MDd compiler +option). Files without that suffix use static versions of the runtime +libraries (the /MT or the /MTd option). Please note that one must use +the same option to compile both gtest and the test code. If you use +Visual Studio 2005 or above, we recommend the -md version as /MD is +the default for new projects in these versions of Visual Studio. + +On Mac OS X, open the gtest.xcodeproj in the xcode/ folder using +Xcode. Build the "gtest" target. The universal binary framework will +end up in your selected build directory (selected in the Xcode +"Preferences..." -> "Building" pane and defaults to xcode/build). +Alternatively, at the command line, enter: + + xcodebuild + +This will build the "Release" configuration of gtest.framework in your +default build location. See the "xcodebuild" man page for more +information about building different configurations and building in +different locations. + +If you wish to use the Google Test Xcode project with Xcode 4.x and +above, you need to either: + * update the SDK configuration options in xcode/Config/General.xconfig. + Comment options SDKROOT, MACOS_DEPLOYMENT_TARGET, and GCC_VERSION. If + you choose this route you lose the ability to target earlier versions + of MacOS X. + * Install an SDK for an earlier version. This doesn't appear to be + supported by Apple, but has been reported to work + (http://stackoverflow.com/questions/5378518). + +Tweaking Google Test +-------------------- + +Google Test can be used in diverse environments. The default +configuration may not work (or may not work well) out of the box in +some environments. However, you can easily tweak Google Test by +defining control macros on the compiler command line. Generally, +these macros are named like GTEST_XYZ and you define them to either 1 +or 0 to enable or disable a certain feature. + +We list the most frequently used macros below. For a complete list, +see file include/gtest/internal/gtest-port.h. + +### Choosing a TR1 Tuple Library ### + +Some Google Test features require the C++ Technical Report 1 (TR1) +tuple library, which is not yet available with all compilers. The +good news is that Google Test implements a subset of TR1 tuple that's +enough for its own need, and will automatically use this when the +compiler doesn't provide TR1 tuple. + +Usually you don't need to care about which tuple library Google Test +uses. However, if your project already uses TR1 tuple, you need to +tell Google Test to use the same TR1 tuple library the rest of your +project uses, or the two tuple implementations will clash. To do +that, add + + -DGTEST_USE_OWN_TR1_TUPLE=0 + +to the compiler flags while compiling Google Test and your tests. If +you want to force Google Test to use its own tuple library, just add + + -DGTEST_USE_OWN_TR1_TUPLE=1 + +to the compiler flags instead. + +If you don't want Google Test to use tuple at all, add + + -DGTEST_HAS_TR1_TUPLE=0 + +and all features using tuple will be disabled. + +### Multi-threaded Tests ### + +Google Test is thread-safe where the pthread library is available. +After #include "gtest/gtest.h", you can check the GTEST_IS_THREADSAFE +macro to see whether this is the case (yes if the macro is #defined to +1, no if it's undefined.). + +If Google Test doesn't correctly detect whether pthread is available +in your environment, you can force it with + + -DGTEST_HAS_PTHREAD=1 + +or + + -DGTEST_HAS_PTHREAD=0 + +When Google Test uses pthread, you may need to add flags to your +compiler and/or linker to select the pthread library, or you'll get +link errors. If you use the CMake script or the deprecated Autotools +script, this is taken care of for you. If you use your own build +script, you'll need to read your compiler and linker's manual to +figure out what flags to add. + +### As a Shared Library (DLL) ### + +Google Test is compact, so most users can build and link it as a +static library for the simplicity. You can choose to use Google Test +as a shared library (known as a DLL on Windows) if you prefer. + +To compile *gtest* as a shared library, add + + -DGTEST_CREATE_SHARED_LIBRARY=1 + +to the compiler flags. You'll also need to tell the linker to produce +a shared library instead - consult your linker's manual for how to do +it. + +To compile your *tests* that use the gtest shared library, add + + -DGTEST_LINKED_AS_SHARED_LIBRARY=1 + +to the compiler flags. + +Note: while the above steps aren't technically necessary today when +using some compilers (e.g. GCC), they may become necessary in the +future, if we decide to improve the speed of loading the library (see +http://gcc.gnu.org/wiki/Visibility for details). Therefore you are +recommended to always add the above flags when using Google Test as a +shared library. Otherwise a future release of Google Test may break +your build script. + +### Avoiding Macro Name Clashes ### + +In C++, macros don't obey namespaces. Therefore two libraries that +both define a macro of the same name will clash if you #include both +definitions. In case a Google Test macro clashes with another +library, you can force Google Test to rename its macro to avoid the +conflict. + +Specifically, if both Google Test and some other code define macro +FOO, you can add + + -DGTEST_DONT_DEFINE_FOO=1 + +to the compiler flags to tell Google Test to change the macro's name +from FOO to GTEST_FOO. Currently FOO can be FAIL, SUCCEED, or TEST. +For example, with -DGTEST_DONT_DEFINE_TEST=1, you'll need to write + + GTEST_TEST(SomeTest, DoesThis) { ... } + +instead of + + TEST(SomeTest, DoesThis) { ... } + +in order to define a test. + +Upgrating from an Earlier Version +--------------------------------- + +We strive to keep Google Test releases backward compatible. +Sometimes, though, we have to make some breaking changes for the +users' long-term benefits. This section describes what you'll need to +do if you are upgrading from an earlier version of Google Test. + +### Upgrading from 1.3.0 or Earlier ### + +You may need to explicitly enable or disable Google Test's own TR1 +tuple library. See the instructions in section "Choosing a TR1 Tuple +Library". + +### Upgrading from 1.4.0 or Earlier ### + +The Autotools build script (configure + make) is no longer officially +supportted. You are encouraged to migrate to your own build system or +use CMake. If you still need to use Autotools, you can find +instructions in the README file from Google Test 1.4.0. + +On platforms where the pthread library is available, Google Test uses +it in order to be thread-safe. See the "Multi-threaded Tests" section +for what this means to your build script. + +If you use Microsoft Visual C++ 7.1 with exceptions disabled, Google +Test will no longer compile. This should affect very few people, as a +large portion of STL (including ) doesn't compile in this mode +anyway. We decided to stop supporting it in order to greatly simplify +Google Test's implementation. + +Developing Google Test +---------------------- + +This section discusses how to make your own changes to Google Test. + +### Testing Google Test Itself ### + +To make sure your changes work as intended and don't break existing +functionality, you'll want to compile and run Google Test's own tests. +For that you can use CMake: + + mkdir mybuild + cd mybuild + cmake -Dgtest_build_tests=ON ${GTEST_DIR} + +Make sure you have Python installed, as some of Google Test's tests +are written in Python. If the cmake command complains about not being +able to find Python ("Could NOT find PythonInterp (missing: +PYTHON_EXECUTABLE)"), try telling it explicitly where your Python +executable can be found: + + cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR} + +Next, you can build Google Test and all of its own tests. On *nix, +this is usually done by 'make'. To run the tests, do + + make test + +All tests should pass. + +### Regenerating Source Files ### + +Some of Google Test's source files are generated from templates (not +in the C++ sense) using a script. A template file is named FOO.pump, +where FOO is the name of the file it will generate. For example, the +file include/gtest/internal/gtest-type-util.h.pump is used to generate +gtest-type-util.h in the same directory. + +Normally you don't need to worry about regenerating the source files, +unless you need to modify them. In that case, you should modify the +corresponding .pump files instead and run the pump.py Python script to +regenerate them. You can find pump.py in the scripts/ directory. +Read the Pump manual [2] for how to use it. + + [2] http://code.google.com/p/googletest/wiki/PumpManual + +### Contributing a Patch ### + +We welcome patches. Please read the Google Test developer's guide [3] +for how you can contribute. In particular, make sure you have signed +the Contributor License Agreement, or we won't be able to accept the +patch. + + [3] http://code.google.com/p/googletest/wiki/GoogleTestDevGuide + +Happy testing! diff --git a/libs/libvpx/third_party/googletest/src/include/gtest/gtest.h b/libs/libvpx/third_party/googletest/src/include/gtest/gtest.h new file mode 100644 index 0000000000..4f3804f703 --- /dev/null +++ b/libs/libvpx/third_party/googletest/src/include/gtest/gtest.h @@ -0,0 +1,20061 @@ +// Copyright 2005, Google Inc. +// All rights reserved. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are +// met: +// +// * Redistributions of source code must retain the above copyright +// notice, this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above +// copyright notice, this list of conditions and the following disclaimer +// in the documentation and/or other materials provided with the +// distribution. +// * Neither the name of Google Inc. nor the names of its +// contributors may be used to endorse or promote products derived from +// this software without specific prior written permission. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +// A PARTICULAR PURPOSE ARE DISCLAIMED.

This abstraction allows applications using this SDK to + easily support multiple video formats with minimal code duplication or + "special casing." This section describes the interface common to all codecs. + For codec-specific details, see the \ref codecs page. + + The following sections are common to all codecs: + - \ref usage_types + - \ref usage_features + - \ref usage_init + - \ref usage_errors + + For more information on decoder and encoder specific usage, see the + following pages: + \if decoder + \li \subpage usage_decode + \endif + \if encoder + \li \subpage usage_encode + \endif + + \section usage_types Important Data Types + There are two important data structures to consider in this interface. + + \subsection usage_ctxs Contexts + A context is a storage area allocated by the calling application that the + codec may write into to store details about a single instance of that codec. + Most of the context is implementation specific, and thus opaque to the + application. The context structure as seen by the application is of fixed + size, and thus can be allocated with automatic storage or dynamically + on the heap. + + Most operations require an initialized codec context. Codec context + instances are codec specific. That is, the codec to be used for the encoded + video must be known at initialization time. See #vpx_codec_ctx_t for further + information. + + \subsection usage_ifaces Interfaces + A codec interface is an opaque structure that controls how function calls + into the generic interface are dispatched to their codec-specific + implementations. Applications \ref MUSTNOT attempt to examine or override + this storage, as it contains internal implementation details likely to + change from release to release. + + Each supported codec will expose an interface structure to the application + as an extern reference to a structure of the incomplete type + #vpx_codec_iface_t. + + \section usage_features Features + Several "features" are defined that are optionally implemented by codec + algorithms. Indeed, the same algorithm may support different features on + different platforms. The purpose of defining these features is that when + they are implemented, they conform to a common interface. The features, or + capabilities, of an algorithm can be queried from it's interface by using + the vpx_codec_get_caps() method. Attempts to invoke features not supported + by an algorithm will generally result in #VPX_CODEC_INCAPABLE. + + \if decoder + Currently defined decoder features include: + - \ref usage_cb + - \ref usage_postproc + \endif + + \section usage_init Initialization + To initialize a codec instance, the address of the codec context + and interface structures are passed to an initialization function. Depending + on the \ref usage_features that the codec supports, the codec could be + initialized in different modes. + + To prevent cases of confusion where the ABI of the library changes, + the ABI is versioned. The ABI version number must be passed at + initialization time to ensure the application is using a header file that + matches the library. The current ABI version number is stored in the + preprocessor macros #VPX_CODEC_ABI_VERSION, #VPX_ENCODER_ABI_VERSION, and + #VPX_DECODER_ABI_VERSION. For convenience, each initialization function has + a wrapper macro that inserts the correct version number. These macros are + named like the initialization methods, but without the _ver suffix. + + + The available initialization methods are: + \if encoder + \li #vpx_codec_enc_init (calls vpx_codec_enc_init_ver()) + \li #vpx_codec_enc_init_multi (calls vpx_codec_enc_init_multi_ver()) + \endif + \if decoder + \li #vpx_codec_dec_init (calls vpx_codec_dec_init_ver()) + \endif + + + \section usage_errors Error Handling + Almost all codec functions return an error status of type #vpx_codec_err_t. + The semantics of how each error condition should be processed is clearly + defined in the definitions of each enumerated value. Error values can be + converted into ASCII strings with the vpx_codec_error() and + vpx_codec_err_to_string() methods. The difference between these two methods is + that vpx_codec_error() returns the error state from an initialized context, + whereas vpx_codec_err_to_string() can be used in cases where an error occurs + outside any context. The enumerated value returned from the last call can be + retrieved from the err member of the decoder context as well. + Finally, more detailed error information may be able to be obtained by using + the vpx_codec_error_detail() method. Not all errors produce detailed error + information. + + In addition to error information, the codec library's build configuration + is available at runtime on some platforms. This information can be returned + by calling vpx_codec_build_config(), and is formatted as a base64 coded string + (comprised of characters in the set [a-z_a-Z0-9+/]). This information is not + useful to an application at runtime, but may be of use to vpx for support. + + + \section usage_deadline Deadline + Both the encoding and decoding functions have a deadline + parameter. This parameter indicates the amount of time, in microseconds + (us), that the application wants the codec to spend processing before + returning. This is a soft deadline -- that is, the semantics of the + requested operation take precedence over meeting the deadline. If, for + example, an application sets a deadline of 1000us, and the + frame takes 2000us to decode, the call to vpx_codec_decode() will return + after 2000us.

It + processes packets of compressed data passed by the application, producing + decoded images. The decoder expects packets to comprise exactly one image + frame of data. Packets \ref MUST be passed in decode order. If the + application wishes to associate some data with the frame, the + user_priv member may be set. The deadline + parameter controls the amount of time in microseconds the decoder should + spend working on the frame. This is typically used to support adaptive + \ref usage_postproc based on the amount of free CPU time. For more + information on the deadline parameter, see \ref usage_deadline. + + \ref samples + + + \section usage_cb Callback Based Decoding + There are two methods for the application to access decoded frame data. Some + codecs support asynchronous (callback-based) decoding \ref usage_features + that allow the application to register a callback to be invoked by the + decoder when decoded data becomes available. Decoders are not required to + support this feature, however. Like all \ref usage_features, support can be + determined by calling vpx_codec_get_caps(). Callbacks are available in both + frame-based and slice-based variants. Frame based callbacks conform to the + signature of #vpx_codec_put_frame_cb_fn_t and are invoked once the entire + frame has been decoded. Slice based callbacks conform to the signature of + #vpx_codec_put_slice_cb_fn_t and are invoked after a subsection of the frame + is decoded. For example, a slice callback could be issued for each + macroblock row. However, the number and size of slices to return is + implementation specific. Also, the image data passed in a slice callback is + not necessarily in the same memory segment as the data will be when it is + assembled into a full frame. For this reason, the application \ref MUST + examine the rectangles that describe what data is valid to access and what + data has been updated in this call. For all their additional complexity, + slice based decoding callbacks provide substantial speed gains to the + overall application in some cases, due to improved cache behavior. + + + \section usage_frame_iter Frame Iterator Based Decoding + If the codec does not support callback based decoding, or the application + chooses not to make use of that feature, decoded frames are made available + through the vpx_codec_get_frame() iterator. The application initializes the + iterator storage (of type #vpx_codec_iter_t) to NULL, then calls + vpx_codec_get_frame repeatedly until it returns NULL, indicating that all + images have been returned. This process may result in zero, one, or many + frames that are ready for display, depending on the codec. + + + \section usage_postproc Postprocessing + Postprocessing is a process that is applied after a frame is decoded to + enhance the image's appearance by removing artifacts introduced in the + compression process. It is not required to properly decode the frame, and + is generally done only when there is enough spare CPU time to execute + the required filters. Codecs may support a number of different + postprocessing filters, and the available filters may differ from platform + to platform. Embedded devices often do not have enough CPU to implement + postprocessing in software. The filter selection is generally handled + automatically by the codec, depending on the amount of time remaining before + hitting the user-specified \ref usage_deadline after decoding the frame. + + +*/ diff --git a/libs/libvpx/video_common.h b/libs/libvpx/video_common.h new file mode 100644 index 0000000000..44b27a8390 --- /dev/null +++ b/libs/libvpx/video_common.h @@ -0,0 +1,23 @@ +/* + * Copyright (c) 2014 The WebM project authors.

The reason for the change was to remove the extruding code from the low level row functions, allowing 3 functions to sshare the same row functions - ARGBScale, I420Scale, and ARGBInterpolate. Then the one function was ported to many cpu variations: SSE2, SSSE3, AVX2, Neon and 'Any' version for any number of pixels and alignment. The function is also specialized for 0,25,50,75%. + +The above goes still has the potential to read the last pixel 100% and last pixel + 1 0%, which may cause a memory exception.

+ x = dx / 2 - 0.5; + +This would start at -0.5 and go to last pixel + 0.5, sampling 50% from last pixel + 1. +Then clamping would be needed. On GPUs there are numerous ways to clamp. + +1. Clamp the coordinate to the edge of the texture, duplicating the first and last pixel. +2. Blend with a constant color, such as transparent black. Typically best for fonts. +3. Mirror the UV coordinate, which is similar to clamping. Good for continuous tone images. +4. Wrap the coordinate, for texture tiling. +5. Allow the coordinate to index beyond the image, which may be the correct data if sampling a subimage. +6. Extrapolate the edge based on the previous pixel. pixel -0.5 is computed from slope of pixel 0 and 1. + +Some of these are computational, even for a GPU, which is one reason textures are sometimes limited to power of 2 sizes. +We do care about the clipping case, where allowing coordinates to become negative and index pixels before the image is the correct data. But normally for simple scaling, we want to clamp to the edge pixel. For example, if bilinear scaling from 3x3 to 30x30, we’d essentially want 10 pixels of each of the original 3 pixels. But we want the original pixels to land in the middle of each 10 pixels, at offsets 5, 15 and 25. There would be filtering between 5 and 15 between the original pixels 0 and 1. And filtering between 15 and 25 from original pixels 1 and 2. The first 5 pixels are clamped to pixel 0 and the last 5 pixels are clamped to pixel 2. +The easiest way to implement this is copy the original 3 pixels to a buffer, and duplicate the first and last pixels. 0,1,2 becomes 0, 0,1,2, 2. Then implement a filtering without clamping. We call this source extruding. Its only necessary on up sampling, since down sampler will always have valid surrounding pixels. +Extruding is practical when the image is already copied to a temporary buffer. It could be done to the original image, as long as the original memory is restored, but valgrind and/or memory protection would disallow this, so it requires a memcpy to a temporary buffer, which may hurt performance. The memcpy has a performance advantage, from a cache point of view, that can actually make this technique faster, depending on hardware characteristics. +Vertical extrusion can be done with a memcpy of the first/last row, or clamping a pointer. + + +The other way to implement clamping is handle the edges with a memset. e.g. Read first source pixel and memset the first 5 pixels. Filter pixels 0,1,2 to 5 to 25. Read last pixel and memset the last 5 pixels. Blur is implemented with this method like this, which has 3 loops per row - left, middle and right. + +Box filter is only used for 2x down sample or more. Its based on integer sized boxes. Technically it should be filtered edges, but thats substantially slower (roughly 100x), and at that point you may as well do a cubic filter which is more correct. + +Box filter currently sums rows into a row buffer. It does this with + +Mirroring will use the same slope as normal, but with a negative. +The starting coordinate needs to consider the scale factor and filter. e.g. box filter of 30x30 to 3x3 with mirroring would use -10 for step, but x = 20. width (30) - dx. + +Step needs to be accurate, so it uses an integer divide. This is as much as 5% of the profile. An approximated divide is substantially faster, but the inaccuracy causes stepping beyond the original image boundaries. 3 general solutions: + +1. copy image to buffer with padding. allows for small errors in stepping. +2. hash the divide, so common values are quickly found. +3. change api so caller provides the slope. diff --git a/libs/libyuv/docs/formats.md b/libs/libyuv/docs/formats.md new file mode 100644 index 0000000000..a7cfed8218 --- /dev/null +++ b/libs/libyuv/docs/formats.md @@ -0,0 +1,133 @@ +# Introduction + +Formats (FOURCC) supported by libyuv are detailed here. + +# Core Formats + +There are 2 core formats supported by libyuv - I420 and ARGB.

If this +// flag is empty, nothing happens here. If it contains a string, +// however, then HandleCommandLineCompletions() will hijack the +// process, attempting to identify the intention behind this +// completion. Regardless of the outcome of this deduction, the +// process will be terminated, similar to --helpshort flag +// handling. +// +// ** Overview of Bash completions: +// Bash can be told to programatically determine completions for the +// current 'cursor word'. It does this by (in this case) invoking a +// command with some additional arguments identifying the command +// being executed, the word being completed, and the previous word +// (if any). Bash then expects a sequence of output lines to be +// printed to stdout. If these lines all contain a common prefix +// longer than the cursor word, bash will replace the cursor word +// with that common prefix, and display nothing. If there isn't such +// a common prefix, bash will display the lines in pages using 'more'. +// +// ** Strategy taken for command line completions: +// If we can deduce either the exact flag intended, or a common flag +// prefix, we'll output exactly that. Otherwise, if information +// must be displayed to the user, we'll take the opportunity to add +// some helpful information beyond just the flag name (specifically, +// we'll include the default flag value and as much of the flag's +// description as can fit on a single terminal line width, as specified +// by the flag --tab_completion_columns). Furthermore, we'll try to +// make bash order the output such that the most useful or relevent +// flags are the most likely to be shown at the top. +// +// ** Additional features: +// To assist in finding that one really useful flag, substring matching +// was implemented. Before pressing a to get completion for the +// current word, you can append one or more '?' to the flag to do +// substring matching. Here's the semantics: +// --foo Show me all flags with names prefixed by 'foo' +// --foo? Show me all flags with 'foo' somewhere in the name +// --foo?? Same as prior case, but also search in module +// definition path for 'foo' +// --foo??? Same as prior case, but also search in flag +// descriptions for 'foo' +// Finally, we'll trim the output to a relatively small number of +// flags to keep bash quiet about the verbosity of output. If one +// really wanted to see all possible matches, appending a '+' to the +// search word will force the exhaustive list of matches to be printed. +// +// ** How to have bash accept completions from a binary: +// Bash requires that it be informed about each command that programmatic +// completion should be enabled for. Example addition to a .bashrc +// file would be (your path to gflags_completions.sh file may differ): + +/* +$ complete -o bashdefault -o default -o nospace -C \ + '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \ + time env binary_name another_binary [...] +*/ + +// This would allow the following to work: +// $ /path/to/binary_name --vmodule +// Or: +// $ ./bin/path/another_binary --gfs_u +// (etc) +// +// Sadly, it appears that bash gives no easy way to force this behavior for +// all commands. That's where the "time" in the above example comes in. +// If you haven't specifically added a command to the list of completion +// supported commands, you can still get completions by prefixing the +// entire command with "env". +// $ env /some/brand/new/binary --vmod +// Assuming that "binary" is a newly compiled binary, this should still +// produce the expected completion output. + + +#ifndef GOOGLE_GFLAGS_COMPLETIONS_H_ +#define GOOGLE_GFLAGS_COMPLETIONS_H_ + +namespace google { + +void HandleCommandLineCompletions(void); + +} + +#endif // GOOGLE_GFLAGS_COMPLETIONS_H_ diff --git a/libs/libyuv/third_party/gflags/gen/posix/include/private/config.h b/libs/libyuv/third_party/gflags/gen/posix/include/private/config.h new file mode 100644 index 0000000000..98d8e1abd1 --- /dev/null +++ b/libs/libyuv/third_party/gflags/gen/posix/include/private/config.h @@ -0,0 +1,110 @@ +/* src/config.h.

If this +// flag is empty, nothing happens here. If it contains a string, +// however, then HandleCommandLineCompletions() will hijack the +// process, attempting to identify the intention behind this +// completion. Regardless of the outcome of this deduction, the +// process will be terminated, similar to --helpshort flag +// handling. +// +// ** Overview of Bash completions: +// Bash can be told to programatically determine completions for the +// current 'cursor word'. It does this by (in this case) invoking a +// command with some additional arguments identifying the command +// being executed, the word being completed, and the previous word +// (if any). Bash then expects a sequence of output lines to be +// printed to stdout. If these lines all contain a common prefix +// longer than the cursor word, bash will replace the cursor word +// with that common prefix, and display nothing. If there isn't such +// a common prefix, bash will display the lines in pages using 'more'. +// +// ** Strategy taken for command line completions: +// If we can deduce either the exact flag intended, or a common flag +// prefix, we'll output exactly that. Otherwise, if information +// must be displayed to the user, we'll take the opportunity to add +// some helpful information beyond just the flag name (specifically, +// we'll include the default flag value and as much of the flag's +// description as can fit on a single terminal line width, as specified +// by the flag --tab_completion_columns). Furthermore, we'll try to +// make bash order the output such that the most useful or relevent +// flags are the most likely to be shown at the top. +// +// ** Additional features: +// To assist in finding that one really useful flag, substring matching +// was implemented. Before pressing a to get completion for the +// current word, you can append one or more '?' to the flag to do +// substring matching. Here's the semantics: +// --foo Show me all flags with names prefixed by 'foo' +// --foo? Show me all flags with 'foo' somewhere in the name +// --foo?? Same as prior case, but also search in module +// definition path for 'foo' +// --foo??? Same as prior case, but also search in flag +// descriptions for 'foo' +// Finally, we'll trim the output to a relatively small number of +// flags to keep bash quiet about the verbosity of output. If one +// really wanted to see all possible matches, appending a '+' to the +// search word will force the exhaustive list of matches to be printed. +// +// ** How to have bash accept completions from a binary: +// Bash requires that it be informed about each command that programmatic +// completion should be enabled for. Example addition to a .bashrc +// file would be (your path to gflags_completions.sh file may differ): + +/* +$ complete -o bashdefault -o default -o nospace -C \ + '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \ + time env binary_name another_binary [...] +*/ + +// This would allow the following to work: +// $ /path/to/binary_name --vmodule +// Or: +// $ ./bin/path/another_binary --gfs_u +// (etc) +// +// Sadly, it appears that bash gives no easy way to force this behavior for +// all commands. That's where the "time" in the above example comes in. +// If you haven't specifically added a command to the list of completion +// supported commands, you can still get completions by prefixing the +// entire command with "env". +// $ env /some/brand/new/binary --vmod +// Assuming that "binary" is a newly compiled binary, this should still +// produce the expected completion output. + + +#ifndef GOOGLE_GFLAGS_COMPLETIONS_H_ +#define GOOGLE_GFLAGS_COMPLETIONS_H_ + +// Annoying stuff for windows -- makes sure clients can import these functions +#ifndef GFLAGS_DLL_DECL +# ifdef _WIN32 +# define GFLAGS_DLL_DECL __declspec(dllimport) +# else +# define GFLAGS_DLL_DECL +# endif +#endif + +namespace google { + +GFLAGS_DLL_DECL void HandleCommandLineCompletions(void); + +} + +#endif // GOOGLE_GFLAGS_COMPLETIONS_H_ diff --git a/libs/libyuv/third_party/gflags/gen/win/include/private/config.h b/libs/libyuv/third_party/gflags/gen/win/include/private/config.h new file mode 100644 index 0000000000..dcca757e49 --- /dev/null +++ b/libs/libyuv/third_party/gflags/gen/win/include/private/config.h @@ -0,0 +1,139 @@ +/* src/config.h.in.
