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