 > Please test current FFmpeg git head, provide the command line you tested
 together with the complete, uncut console output and the model of your
 audio player to make this a valid ticket.

 code to test if that really fixes playback.

 I don't believe that something changed in git head in that matter so I
 believe that setting it up and patching would only waste my precious time.
 I don't want to provide full console output and I think it's predictable
 what mp4box does with the file.

 My audio player is Pentagram Vanquish VOLT.

 > Pls attach the originalFile.m4a for issue reproduce

 It's copyrighted so I cannot do it, but I believe it's a standard m4a file
 from iTunes. MediaInfo shows
 "Format profile : Apple audio with iTunes info"
 I observed that it's not that particular file that causes the issue,
 because a file from unrelated batch causes the same issue when converted
 with ffmpeg.

 What do you need that file for?
