I am not conviced the GAP flag is the solution here. The GAP flag is defined so
that e.g. a filter can pass the incomming buffer unmodified along. In audio
e.g. a silent buffer would remain silent. In video this would be a fully
transparent frame.

I see the point of having a duplicated frame and wanting to take benefit out of
that. Could encoders keep a ref on the last frame and apply the duplicate
optimisation if the get the same buffer again. That should work as videorate
uses subbuffers for duplicated frames.
