putting this in libvo raises the question...shouldn't this type of
thing eventually be mencoder's territory? right now mencoder only
supports avi, but it'd be nice if we could eventually get mpeg
(including vcd-compliant), ogg, and asf muxers working with it. might
it even be appropriate to also move png, yuv4mpeg, etc. output to
mencoder at that point, if we ever get there?
