New API additions should include an explanation of which problems this
solves, how it should be used, and why it is necessary. Otherwise we
have no reference to even judge the usefulness of such an API.

Looking at the patch, the change to av_frame_ref looks fishy to me.
Why would dst reference itself, and not src?
