Can you share the output you get when you run ffmpeg -version and which ffmpeg?

Failed to reproduce the issue now, closing it until reproducible way is found.

[anweshknayak]

I guess the issue is still open ?

[dstftw]

It's still closed as you may notice.

[anweshknayak]

I mean the issue still exists. It was meant to be reproduced ?

[dstftw]

No. Open a new issue if you can reproduce.

[Vdragon]

I still can't reproduce the same issue.
