Haruhiko Yamagata Posted February 28, 2012 Posted February 28, 2012 Hi, If I try to play this file, DVBViewer has black screen. Sometimes one or two frames are shown. Audio plays with noise. Because I'm a developer of ffdshow, I've tried to debug it. Video frames have timestamps around 00:49:05.136 while audio frames have timestamps around 00:00:02.819. AV sync is impossible and the playback fails. support.zip Quote
Derrick Posted February 28, 2012 Posted February 28, 2012 ..don't waste your time on a broken stream Quote
Griga Posted February 28, 2012 Posted February 28, 2012 AV sync is impossible and the playback fails. The original DVB PTS are already way out of sync. You can see it in DVBViewer on View -> Filters -> DVB Source -> klick PTS -> DVB. The DVBViewer (Source) Filter translates the DVB PTS to DirectShow timestamps, but doesn't correct such differences. Playback fails here with VLC and Haali as well.. Quote
Haruhiko Yamagata Posted February 28, 2012 Author Posted February 28, 2012 hmm... You seem to be correct. I thought MPC-HC played the file, but there was no audio... Quote
Derrick Posted February 28, 2012 Posted February 28, 2012 Audio plays with noise. ..it's the audio that contains noise. If you demux audio and play it with any player, the noise is still there. Maybe the video encoding is also questionable. The stream info says frame mode: "progressive" Quote
Haruhiko Yamagata Posted February 28, 2012 Author Posted February 28, 2012 Thanks for many and quick replies. I expected the stream was correct because ASTRA seemed to be a professional company. Actually I was wrong. Quote
Derrick Posted February 28, 2012 Posted February 28, 2012 ..don't expect too much from a very old test loop Quote
