I'd very much prefer if you can do it. Adapt the codebase in a way that
simply flipping the FF_API_XVMC define from 1 to 0 disables the
deprecated code (and potentially enables new code in necessary, like the
stuff in pixfmt.h).
I have no way to test this functionality so anything i could do would be
just a wild guess.
Thanks a lot.
