Yes, that would be possible. The player code is in a separate .cpp file.

Thanks, that would solve this problem. :)

Perhaps these functions do not need to become part of the *public* API. The 
xine_stream_master_slave() API call could also be used for this purpose, 
where 'XINE_MASTER_SLAVE_CLOCK' would give the slave it's own clock. This 
would detach the stream from the global clock.

int xine_stream_master_slave( ... ) {
  if ((affection & XINE_MASTER_SLAVE_CLOCK) && master == NULL) {
    if (slave->clock == NULL) {
      slave->clock = xine_clock_init();
      xine_stream_attach_clock(slave, slave->clock);
    }
  } else if (slave->clock != NULL) {
    xine_stream_detach_clock (slave, slave->clock);
    xine_clock_dispose (slave);
    slave->clock = NULL;
  }
  if (master != NULL) {
    ...
  }
  return 1;
}

The xine_dispose() function would also have to be modified to destroy the 
clock (if not NULL).

Thanks.
