Thank you, Carl Eugen,

Here is the sample https://github.com/leandromoreira/temp-chunks it has 4
mpeg-ts files.
You can observe the negative pts behavior with ffprobe
<https://github.com/leandromoreira/temp-chunks/blob/master/check_pts_wraparound_ffprobe.sh>.
The first two files are growing in PTS just as expected (positve) and from
the 3rd file on, it starts to show negative PTS.

Let me know if you have any questions.

Thanks
