Translate position to the total running time using the currently configured segment. Compared to Segment.toRunningTime this function can return negative running-time.

This function is typically used by elements that need to synchronize buffers against the clock or each other.

position can be any value and the result of this function for values outside of the segment is extrapolated.

When 1 is returned, position resulted in a positive running-time returned in running_time.

When this function returns -1, the returned running_time should be negated to get the real negative running time.
