Or, even simpler, we could test with the original file (before
being remuxed or transcoded with FFmpeg) to know for sure
if FFmpeg needs a change.

(I assume that your test doesn't really help because our
muxer is known not to be compliant afair.)

We could use some video/audio analyzer tools to check whether the sample ts 
file is correct. If there is no problem, we can think there is bug in ffmpeg, 
e.g. ts demuxer.


Thanks!

If the issue is only reproducible with files created with FFmpeg,
I would assume an issue with the muxed file / the muxer.

I just find the issue with the large sample files.

Not sure what you are trying to show but this file was created with
FFmpeg and is therefore typically not a good example.

Or to say it differently: If the issue can be shown with a file
created by FFmpeg, why did you upload a (large) sample?
