Thank you for your response.

What do you suggest to do ?

do you need files to check in deep ?

Waiting for a fix comes to mind.
But if you can fix the issue yourself, sending a patch made with git format-patch to the FFmpeg development mailing list is even better.

do you need files to check in deep ?

Originally: Yes.
But now: What is wrong with the files I provided?

Waiting for a fix comes to mind.

Or use an older FFmpeg binary.
