Additionally if do not want to use the heartbeat function you can use XScreenSaverSuspend(dpy, True) call
and then XResetScreenSaver(dpy) once to be sure that previously activated mode will be disabled.
If you remotely control the mplayer program you should do these two calls before starting playing
and call XScreenSaverSuspend(dpy, False) in case of pause/stop/end of playing.
