Thanks. I think I understand the problem: it is not that the timestamps
are not unwrapped, it is that they are unwrapped twice, because for some
reason lavf defaults to parameters tuned for MPEG.

Thanks for the patch, it works fine to me.
Disable is good enough to prevent unnecessary wrap control.
