[Libquicktime-devel] FFmpeg plugin resync DNW for out-of-order B-frames after full sync keyframes

[Derek C. <der...@mi...>]

Example with XDCAM file:

   1. (IBBP... bitstream with 'ctts' 2, -1, -1, 2 ...).
   2. After seeking (or decoding) to frame 2, use
   quicktime_set_video_position() to then seek backwards to frame 1.
   3. get_bitstream_sync_frame() returns 0.
   4. decoded_frames_to_discard becomes < 0 despite "// Should not be < 0
   unless the stream is broken."

Please see possible fix attached.
