So we have this clip. If I
ffmpeg -i 041336917.mov out.mov
...then...
[root@ip-10-149-69-183 apa]# ffmpeg -i out.mov

The only way around it seems to be...
ffmpeg -i 041336917.mov -ss 00:00:06.6 out.mov
...
Duration: 00:00:19.62, start: 0.000000, bitrate: 2908 kb/s
This is a user submitted file and I don't know how the user produced it.
exiftool says nothing in particular except for
"Com Apple Finalcutstudio Media Uuid"
Is the metadata broken? Can it be fixed? Googling around, adding -async
1 is suggested. But here's no audio here, so an badly aligned audio does
not seem to be the cause.
Thanks,
Marcus
