Hello, I'm using Cinelerra 2.1.0-2svn20070209 on Debian Etch AMD64 from http://giss.tv ./ Packages.
When opening an MPEG Video clip (mpeg1video, mp3 audio, converted from flash video using ffmpeg) of several minutes (the video plays just fine in Xine) , I have the following problem. When playing the video, audio and video are in sync at the beginning. However, as the video progresses, the audio starts to lag (about 1s per minute of video). The audio and video tracks are of equal length in the main window and show up as such. Due to the audio lagging, I can not get the last part of the audio to play - it simply seems missing from the audio track (although the audio and video tracks show up as being of equal length). Even when I only send the audio track to the Compositor window, I never hear the last part. This audio lag (and missing endpiece) also affects rendering to (at least) MPEG1 video and mp3 audio. The lag is just the same in the rendered file as in the compositor window. Actually what happens is when I cut some part of both video and audio tracks, I have part of the video track and a delayed part of the audio track, which then results in a no-good output file. I have googled for mpeg sync problems and have some people with similar problems, but have not found an effective answer to my problem. Does anyone know what's going on? Thanks, Pieter _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
