Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

I agree that there is an issue but the way you describe is clearly invalid: I don't think the command line you provide works with 3.0, please test (again).

And please test current FFmpeg git head, this is required for a valid bug report.

[kwsk]

I tried it with git head (N-81008-g87e9cef)
But, It failed with same error

I uploaded sample file for test

I have asked what this commit fixes but did not get an answer:
https://ffmpeg.org/pipermail/ffmpeg-devel/2016-August/197593.html
Since I don't understand how above commit is meant to work, I don't know how to fix this issue.
