REF: https://github.com/mpv-player/mpv/wiki/FFmpeg-versus-Libav

Found a good resource on the pros & cons of both. Basically ffmpeg integrates every change libav makes, libav doesn't do that with ffmpeg. Thus ffmpeg is basically a superset of libav, it does everything that libav does and more. New(and useful) APIs in ffmpeg do not make their way into libav, unfortunately. Seems that the ffmpeg developer is banned from the libav irc channel(lol).
