As I mentioned in ticket http://trac.ffmpeg.org/ticket/7876 this is
not my code, I just adapted it for current git. It is also very old
code (back from 2012), probably it fitted OK back then. This code
fixes this specific issue reported in the ticket. If it breaks other
things, then of course it can't be commited. Still there is a need for
a fix for the reported issue in the ticket, as it is you can't
transcode with -copyts above 26,5 hours, it fails after that.
