I have a video file which is only corrupted part of the way through (around 4:53 is where it starts messing up). When I try to run it through untrunc, it gives me the following output:

Reading: /home/chiraag/Videos/Canon/2016-05-27/MVI_0350.MP4
Composition time offset atom found. Out of order samples possible.
Sample dependency flag atom found. I and P frames might need to recover that info.

I can send you the videos privately (I'd rather not share them here) if that will help with your analysis of what is going on.

Any ideas?

@ponchio should I send you the videos?
