Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

The original file definitely has some issues in timestamp, but it plays fine in all the players I tested. The output, on the other hand, doesn't. It will just play a split of seconds.

The problem also happens when remuxing to ts, mkv, or avi. (Interestingly, no "Non-monotonous DTS in output stream" spamming when converting to mkv).

Transcoding it (simply removing -c copy) also resulted in broken file.

Probably a duplicate.

Replying to fireattack:
confirmed, adding "-ignore_editlist 1" works

This mp4 has a strange edit list that, only one entry, with duration of 0, which is telling the player to render nothing.

Although VLC and window media player plays well, I think they just simply ignore the edit list. From this perspective, I think ffmpeg is doing the right thing.

Ah, never heard of that and it explains it.

Thanks.
