Resolution: invalid
Status: newclosed

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.
