    Unknown encoder '-libvpx'

    Doh, remove the minus sign from in front of libvpx!

    Have you installed libvpx0? It is in the 10.04 repos and will presumably be in all others as well.

    However, if you have not compiled ffmpeg yourself, you should now be using the command avconv which is in the libav-tools package instead in 12.10.
