This directory contains files used in gecko builds from FFmpeg
|
|
(http://ffmpeg.org). The current files are from FFmpeg as of
|
|
revision n4.0.2-6-g2be51cbeea
|
|
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
|
|
git checkout n4.0.2-6-g2be51cbeea

All source files match their path from the library's source archive.
|
|
|
|
Currently, we only use the vp8, vp9, mp3, and flac portion of the library. 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 \

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.
