hacks to produce libffmpegsumo.so

building ffmpegsumo is a PITA, you need to fight with chromium’s build system, but so far this seems to work:

GYP_DEFINES=”proprietary_codecs=1 target_arch=x64 branding=Chrome” ./build/gyp_chromium build/all.gyp

–> use the hacks to produce the ffmpegsumo and ffmpeg_yasm ninja files <–

./depot_tools/ninja -v -j4 -C out/Release ffmpegsumo

rm cfilez
rm afilez
for i in `find build.x64.linux/Chromium -name '*.o' | sed s/Chromium/' '/ | cut -d' ' -f2`; do
d=`dirname $i`;
f=`basename $i | sed s/'\.o$'// | egrep -oe '[^ ]+$'`;
[ -f ./${d}/${f}.c ] && echo "${d} ${f}" >> cfilez
[ -f ./${d}/${f}.asm ] && echo "${d} ${f}" >> afilez
done
sh make-sumo.sh > ffmpegsumo.ninja
sh make-yasm.sh > ffmpeg_yasm.ninja
