Hi all. I have an adaptec avc-2010 (pci card) set up using Ubuntu 7.04. Recording using "cat /dev/video0 > test.mpg" works absolutely perfectly (I can play the dump back using any mpeg-2 decoding software). Watching the stream "live", however, stutters and barfs horribly. I thought that anything that could decode an MPEG-2 stream would work, so I tried the following apps:
1) "mplayer /dev/video0": the status on mplayer shows the video lagging behind the audio. Eventually (once the lag hits about 1 second) I get "Your system is too SLOW to play this!", but I think this is a red-herring, since separate capture and playback consume minimal cpu usage. 2) "vlc -v stream:/dev/video0": works better, but it too stutters with errors such as: [00000357] main private warning: vout synchro warning: pts != current_date (-265627) [00000356] main audio output warning: computed PTS is out of range (51482), clearing out [00000356] main audio output warning: PTS is out of range (38540), dropping buffer [00000356] main audio output warning: output PTS is out of range (64924), clearing out [00000356] main audio output warning: PTS is out of range (8329), dropping buffer [00000356] main audio output warning: PTS is out of range (-15657), dropping buffer [00000356] main audio output warning: PTS is out of range (-29893), dropping buffer [00000356] main audio output warning: computed PTS is out of range (238080), clearing out [00000356] main audio output warning: PTS is out of range (238136), dropping buffer etc... 3) "cat /dev/video0 | xine stdin:/" continually shows "Buffering..." on the on-screen display, I then get about 1 second of video, followed the "Buffering" again. 4) "cat /dev/video0 | gxine stdin:/" does the same as xine (previous example). I assume that this is a driver issue since it affects three/four different playback apps. What do other people use to watch their ivtv-based card "live", and does it (currently) work? Thanks for your input. Jaime :-) _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
