I'll look into fixing it. I see some other stuff, which isn't good though: 2005-12-22 13:27:39.398 Id:1 00:13:18.348 V:139 MP2: 98 2005-12-22 13:27:39.398 Found invalid audio PTS (off by 00:00:00.504) at 15:58:33.424 2005-12-22 13:27:39.398 AUD #1: pts: 00:13:17.940 2005-12-22 13:27:39.398 Id:1 00:13:17.940 V:139 MP2: 97 A backwards moving PTS (from 13:18.348 to 13:17.940) will result in A/V desync. This isn't a transcoder issue, and I don't really know any way to solve it. If your stream is this broken, there isn't much the transcdoer can do. I don't see why the transcoder would make it any worse than it already was though. I don't see anything in the mplayer logs telling me about an A/V desync either except for this: A: 798.3 V: 798.3 A-V: -0.005 ct: 0.553 19952/19952 10% 2% 0.7% 6 0 43% A: 797.9 V: 798.3 A-V: -0.426 ct: 0.549 19953/19953 10% 2% 0.7% 6 0 45% which corresponds to the above backwards moving PTS. It is about 0.5 sec off, and mplayer corrects for it within 2 seconds. So I guess I need a more explicit explanation of what you are seeing, and ideally, a clip around the area of interest that shows it in action. .Geoff _______________________________________________ mythtv-dev mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev
