ffmpeg has many internal components (avformat, avcodec, etc) but none of those are “libav”. libav was a fork of all the ffmpeg code (they took all the code, copied it, renamed their copy to libav, and changed the name of some binaries like changing the ffmpeg binary name to avconv). That fork is dead now. No one is maintaining it. The libav.org site doesn’t exist anymore.
