I agree that a gap flag on a video frame should indicate a duplicate frame.

One problem with using this in theoraenc is that libtheora requires that you
give it the number of duplicates along with the original frame.  Thus, to use
this feature, one would have to implement a one-frame queue inside theoraenc,
increasing the latency of the encoder.

On the other hand, checking the duration of incoming buffers and implementing
videorate functionality in theoraenc, can be done with libtheora as-is, with no
increase in latency.
