Comment:
I made two long mpegts recordings, one contains h264, ac3 and mp2, the
other only aac, both contain a pts-wrap. For both streams, the "Duration"
information is nearly correct.
If you want to reopen this ticket, please explain for which bs / count /
skip values (when using dd to cut the sample) the issue is reproducible /
not reproducible and / or provide a sample, You can upload up to 100MB to
