Notes

mdeslaur

ffmpeg-extra in multiverse needs to have matching version libav-extra is built with tarball produced by libav package as of 2012-12-18, not in libav codebase http://patches.libav.org/patch/20291/ Probably fixed in libav by http://git.libav.org/?p=libav.git;a=commitdiff;h=8099187e897ddc90cb3902332c76fb2542dac308
