38 If you want to use ffmpeg instead of libav, "It should be noted that the
39 users still need to enable USE=ffmpeg on packages with optional libav
40 support as well. Users who want to use ffmpeg instead need to specify
41 USE=-libav in make.conf explicitly."
42
43 Otherwise, set USE=-ffmpeg in /etc/portage/make.conf to stick with libav.
