Reported by:	crazymxm	Owned by:
Priority:	important	Component:	avformat
Version:	git-master	Keywords:	mov edts duration regression
Cc:		Blocked By:

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 ）

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.

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