wrapped_avframe is used all over the place in lavd already.
Is that really a problem, as long as it's within another libav* library?
Given we don't support mix-matching library versions in the first place.

The only real way around that would be a get_size function in lavu, and 
never using AVFrames on the stack, which is done in quite a lot of places.
