While adding a new options for adjusting pts, would it be possible to
handle the case where pts are wrapping around ?

In my case, I use EDL to cut TV shows records, and sometimes, I have a
"end pts < begin pts" (or alike, can't remember exactly) error when
writing the EDL.

However, I don't know mplayer codebase, nor I have an idea how to
cleanly handle this kind of cases (using something like "until now played
timestamp", counting numbers of wraps as well as their max/min), so,
sorry, no patch from me, except if I get leads on that.

Regards.
