I'm just getting it to compile, at first, and they use that. They
probably need a cluebat, then, if that is not a public interface. The
problem here is that they use AVAudioConvert, which is present only in
that header.

I'm not exactly sure if I want to patch this so heavily as to fix the
use of that interface.

I have yet to see which patches can be dropped and which don't. OTOH,
the basics compile and a brief test here works. :)

I think it is fine as is. Not sure if the legal stuff
(debian/copyright etc.) is all in place for an upload to unstable.

I still have to study that to see what can be done and how similar the
interfaces are.

That's the same story as with vo-aacenc/faac.

OK, but the excitement is really huge and I couldn't help sending some
side comments. :) Feel free to reply to the bug only the parts
pertaining to the bug and to the mailing list the other parts (please,
keep me CCed).



Thanks.

P.S.: Now, it compiles with Debian's mpeg2, which is one fewer embedded library.
