Comment (by cehoyos):

 I tested transcoding the input file you attached with FFmpeg 3.4 and the
 output file has severe A/V synchronization issues. I repeated the test
 with current FFmpeg git head and the output file seems to play in-sync but
 this is difficult to verify because of the file content (small desync
 would not be visible afaict). If there still is an issue with current
 FFmpeg git head and the attached input file, please explain how I can
 reproduce / see it.

 Please understand that I am not asking you to analyze the issue using the
 source code: If you are able to do that, you should not have opened a
 ticket but instead send a patch - made with `git format-patch` - to the
 development mailing list. In a ticket on this bug tracker, no analysis is
 required (or asked for), just explain how we can reproduce the problem you
 see.

 Attaching screen-shots of FFmpeg source code is definitely not
 appreciated.
