Yes, if clean enough. :-).

This touches upon what Geza's doing. A single media (what you'd
consider the equivalent of "an AVI file", or "a DVD title", but not "a
DVD disc" or "my iTunes playlist") would be represented by an
AVFormatContext.  Multiple of these would likely have to be
represented as a playlist, and I think Geza had some code for that in
an earlier patch. You'd want to look at that and coordinate for a
common solution.
