Reported by:	crazymxm	Owned by:
Priority:	important	Component:	avformat
Version:	git-master	Keywords:	mov edts duration regression
Cc:		Blocked By:
Blocking:		Reproduced by developer:	yes
Analyzed by developer:	no

Description

The output file has the double duration :
Source video duration :00:01:58.88
output video duration :00:03:57.76

（video's duration is double ，audio's duration is correct. So， the video looks like played twice, with no sound in the second half ）

Please test if the issue you see is reproducible with current FFmpeg git head.

comment:4 by crazymxm, 4 years ago

Now, I try the new version (N-89038-g8329ae7-tessus . Before: version N-82977-g8fd3e02-tessus), the problem remains.

FFmpeg output is correct, that mp4 video track has got two edit list entries, it repeats the same segment of video two times, so the video duration is 3:57.76.

comment:9 by galad, 4 years ago

But the track duration in the tkhd box is not the sum of the edit lists duration, so the file is actually invalid.
