Translate position to the total running time using the currently configured
segment. Position is a value between segment start and stop time.
This function is typically used by elements that need to synchronize to the
global clock in a pipeline. The running time is a constantly increasing value
starting from 0. When Segment.init is called, this value will reset to
0.
This function returns -1 if the position is outside of segment start and stop.
