* Writes any delayed frames in the encoder. This function is called before

* Since an encoder may use both past and future frames to predict

* in a different order from the one it was given.
* For example, when sending frames 1, 2, 3, 4 to the encoder, it may write
* them in the order 1, 4, 2, 3 - first the two frames used for prediction,
* and then the bidirectionally-predicted frames. What this means in practice
* is that the encoder may not immediately produce one output frame for each
* input frame. These delayed frames must be flushed before we close the
* stream. We do this by calling avcodec_encode_video with NULL for the last
