Comment (by Jun):
Replying to [comment:1 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.
> 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.
