Comment (by mkver):

 FFmpeg/Lavf created output.mp4 and this of course includes the the length
 field in the header. Of course this is potentially fixable. But don't
 think that this will fix the other players.
 Oh, and the situation is actually a little bit different than I said.
 There are more duration fields than I have mentioned: Each track has a
 duration field in the track header box; both of them indicate a length of
 30s (all numbers are rounded), although these duration fields should be
 equal to the sum of the durations of the edits in the edit lists (which
 indicate 27s). That the overall movie header duration indicates 30s is
 only consequential.
