Indeed, I did not see anything better. And more fancy stuff, like estimating
the end of the last packet, would not necessarily be more accurate. For
example, for the DVD I was working on, the last audio packet of chapter 1
has pts=90.268 and duration=0.032 while the first audio packet of chapter 2
has pts=0.135267, which puts the reset at pts=90.164733, before the last
packet.

That was the point, although the same change also corrects direct playing.

The way I see it, timestamps resets are just broken, and we do what we can
to limit their bad consequences.

No, but I would gladly do it if you point me to relevant samples.
