Probably check out http://ffmpeg.org/general.html
It will list the file formats supported as well as the audio and video
codecs supported. Note that streams get encoded (or "compressed") with
a particular codec (kind of like an algorithm), and then the streams
get muxed (stuffed into a container (output file format)).

muxing is short for multiplexing. Google and Wikipedia can explain it
better than I can, but it's more or less mixing two different
electronic signals together in a specific way.
