64 * cannot cope with this situation and output the frames in the wrong
65 * order. As a workaround in this case, we use a FIFO of timestamps in
66 * order to remember which input packets had no PTS. Since an
67 * hardware decoder can silently drop frames, this might cause a
68 * growing desynchronization with the actual timestamp. Thus the
69 * circular buffer has a limited size and will overwrite older values.
