FFmpeg embeds "stts" atom in .mov without being asked.

[Felix Handte]

Summary of the bug:

Despite mapping only one stream from each of the two inputs, the output ends up with an extra, third pseudo-stream / atom (which causes Avid to refuse to link the file via AMA).

How to reproduce:

[Carl Eugen Hoyos]

Does it work with older versions?

[Carl Eugen Hoyos]

Does it work if you add -r 24000/1001 to your command line?

[TimNich]

stts is a standard atom which should be in all trak atoms and have at least one table entry. Given that no timecode is specified I wonder if its a broken timecode track.

Replying to nichot20:

stts is a standard atom which should be in all trak atoms and have at least one table entry. Given that no timecode is specified I wonder if its a broken timecode track.

The ticket is likely a duplicate of ticket #2892, this can be verified by testing with -r 24000/1001.

[Carl Eugen Hoyos]

I suspect this problem was fixed today, please test again!

[Carl Eugen Hoyos]

Please reopen this ticket if the problem is still reproducible!
