[xine-devel] FYI: What was that metronom bug fix?

The metronom "unixscr_get_current" used to introduce errors into the timer.
It would gettimeofday, and then set the this->cur_time to it, after working
out this->cur_pts.

The problem was that a rounding error (difference between accuracy of PTS
and tv_usec) was introduced each time the this->cur_time was reset.

The new method never resets this->cur_time, so the error is never
introduced.

The error is only introduced each time someone changes the speed of the
stream.
See the unixscr_set_speed and the new unixscr_set_pivot function.

Cheers
