FFmpeg's libavcodec supports decoding (and with many constraints
encoding) vorbis, as an alternative you can use libvorbis to decode
vorbis audio with libavcodec.

I don't know what fsv is (neither our samples collection nor our
bug tracker know it) but the easiest way to get to an answer
is to test with current FFmpeg:
$ ffmpeg -i input out.mp4
$ ffmpeg -i input out.webm
