>From the ffmpeg website[1]: FFmpeg is the leading multimedia framework ... ... It contains libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample which can be used by applications. As well as ffmpeg, ffserver, ffplay and ffprobe which can be used by end users for transcoding, streaming and playing. So libav does not have all the stuff you want. As said above read the news item it has important information about this setting in Gentoo, anyway what you want is to have this in your make.conf: USE="... -libav ffmpeg ..."
