All the codecs that the AVI muxer supports are supported by  
extension, as well as theora, vorbis, flac, wavpack, and tta. I could  
make a complete list, but I haven't heard of half the codecs listed  
in codec_bmp_tags/codec_wav_tags... Real codecs aren't supported yet,  
but I do plan on supporting them eventually.

As for using it, pretty much any valid command line that starts with  
ffmpeg and ends with .mkv should work, e.g. "ffmpeg -i blah.ogg - 
vcodec mpeg2video -acodec ac3 blah.mkv" It can also be used from  
mencoder, e.g. "mencoder blah2.avi -ovc lavc -oac faac -of lavf -o  
blah2.mkv" but it's possible to produce invalid files that way.
