This directory contains files used in gecko builds from FFmpeg
|
|
(http://ffmpeg.org). The current files are from FFmpeg as of
|
|
revision n4.3.1
|
|
All source files match their path from the library's source archive.
|
|
|
|
Currently, we only use the vp8 and vp9 portion of the library, and only on x86
|
|
based platforms. If this changes, configuration files will most likely
|
|
need to be updated.
|
|
|
|
AVX2 must be disabled on Linux 32 bits due to the use of yasm 1.1 on the build bots.
|
|
Once yasm is upgraded to 1.2 or later, AVX2 code could be re-enabled.
|
|
Add --disable-avx2 to configure on those platforms.
|
|
|
|
configuration files were generated as follow using the configure script:
|
|
./configure --disable-everything --disable-protocols --disable-demuxers --disable-muxers --disable-filters --disable-programs --disable-doc --disable-parsers --enable-parser=aac --enable-parser=flac --enable-parser=h264 --enable-parser=hevc --enable-parser=opus --enable-parser=vorbis --enable-parser=vp8 --enable-parser=vp9 --enable-decoder=aac --enable-decoder=flac --enable-decoder=h264 --enable-decoder=hevc --enable-decoder=mp3 --enable-decoder=opus --enable-decoder=vorbis --enable-decoder=vp8 --enable-decoder=vp9 --disable-static --enable-shared --disable-debug --disable-sdl2 --disable-libxcb --disable-securetransport --disable-iconv --disable-swscale --disable-avdevice --disable-avfilter --disable-avformat --disable-d3d11va --disable-dxva2 --disable-vaapi --disable-vdpau --disable-videotoolbox --enable-asm --enable-x86asm --disable-cuvid --disable-cuda --disable-nvenc --enable-w32threads

The GNU comm utility is a useful tool to compare and extract only the changes.
|
|
|
|
To update the source tree, perform a diff on the files listed in FILES.
|
|
The diffs should typically apply to the ffvpx tree.
|
|
e.g. something like this would do:
|
|
Run in the ffmpeg original tree:
|
|
$ for i in `cat $PATH_CENTRAL/media/ffvpx/FILES`; do git diff $REV_LASTSYNC HEAD >> patch.diff; done
|
|
Then apply patch.diff on the ffvpx tree.
|
|
|
|
Compilation will reveal if any files are missing.
