[MPlayer-users] More precision for elapsed time

[Michael]

Is there an option or a way to increase the precision of elapsed time that
is written to standard output, when playing a video file using mplayer?
By default, its accurate to a tenth of a second. I need the higher accuracy
to use it in conjunction with mkvmerge utility to split my mkv files.
mkvmerge only accepts timestamps and not frame numbers.
