Creates a time mapping with a source and target time range.
Declaration
func CMTimeMappingMake(source: CMTimeRange, target: CMTimeRange) -> CMTimeMappingParameters
- source:

Discussion
The source and target parameters must have durations whose epoch is 0, otherwise the system returns an invalid time mapping.
