-This directory contains files used in goanna builds from FFmpeg
-(http://ffmpeg.org). The current files are from FFmpeg as of
-revision n3.2-65-gee56777
-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 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=vp8 --enable-parser=vp9 --enable-decoder=vp8 --enable-decoder=vp9 --disable-static --enable-shared --disable-debug --disable-sdl --disable-libxcb --disable-securetransport --disable-iconv --disable-swresample --disable-swscale --disable-avdevice --disable-avfilter --disable-avformat --disable-d3d11va --disable-dxva2 --disable-vaapi --disable-vda --disable-vdpau --disable-videotoolbox --enable-asm --enable-yasm

-23 Sept 2016: libavcodec/pthread_frame.c has been patched so as to avoid
-generating large numbers of warnings from TSan (Thread Sanitizer) when
-decoding vp9 streams. This will likely be fixed upstream sometime soon.
-When resyncing with upstream, first un-apply the patch shown at
-https://bugzilla.mozilla.org/show_bug.cgi?id=1274256#c60, then resync,
-then assess whether the patch is still necessary.
