  • Component changed from ffmpeg to undetermined
  • Version changed from 4.2 to unspecified

Is the issue reproducible with current FFmpeg git head? Please provide the command line you tested together with the complete, uncut console output to make this a valid ticket.

comment:4 follow-up: Changed 8 weeks ago by mkver

  • Resolution set to invalid
  • Status changed from new to closed

It's an edit list issue: The video has two edit list entries, both of which tell to play 45s of video from the beginning. Despite there not being 45s of video.

You can use the input option -ignore_editlist 1 to disable applying the edit lists altogether.

I am closing this as invalid. You may reopen it if you have a reason to believe that FFmpeg's behaviour is buggy.
