Richard Neill <[EMAIL PROTECTED]> added the comment: Thanks for your suggestion. I did try that, but it simply doesn't make any difference. Here's the command I ran: ffmpeg -i recording.avi -vcodec copy -acodec copy -async 10 -y resynced.avi
In case it's useful, the original recording was made thus: sudo dvgrab --format dv1 - | ffmpeg -f dv -i - -deinterlace -vcodec mpeg4 -b 5000 -acodec ac3 -ab 128 -f mpegts - > recording.avi Either the -async system is completely broken, or the camera is generating audio which is wrongly timestamped, and therefore cannot be fixed automatically. An option might be to modify -async to allow the user to specify the exact correction which async should apply, overriding the automatic value.
