I was curious as to which distros default to ffmpeg and which default to libav, looking at my distro of choice (Arch Linux) it's ffmpeg, there's no libav in the official repos as far as I can tell and programs like VLC, Blender, MPlayer2 all link to ffmpeg, Mplayer on the other hand links directly against the core codec libraries unless I'm mistaken. The article states that Debian (and Ubuntu?) uses libav (and yes, the bs about ffmpeg being deprecated is obviously a douchebag move), so does anyone know what other distros are defaulting to, Gentoo, Fedora, OpenSUSE etc?
