DVD playback had some trouble with PTS resets: libavformat's genpts feature would try reading until EOF (worst case) to find a new usable PTS in case a packet's PTS is not set correctly. Especially with slow DVD access, this would make the player to appear frozen. Reimplement it partially in demux_lavf.c, and use that code in the DVD case. This is heavily "inspired" by the code in av_read_frame from libavformat/utils.c. The difference is that we stop reading if no PTS has been found after 50 packets (consider this a heuristic). Also, we don't bother with the PTS wrapping and last-frame-before-EOF handling. Even with normal PTS wraps, the player frontend will go to hell for the duration of a frame anyway, and should recover quickly after that. The terribleness of this commit is mostly that we duplicate libavformat functionality, and that we suddenly need a packet queue. |
