CMTimeRangeMBS class

Type	Topic	Plugin	Version	macOS	Windows	Linux	Console & Web	iOS
class	AVFoundation	MBS AVFoundation Plugin	13.2	Yes	No	No	Yes, macOS only	No

Function: The class that represent time ranges.
Example:

dim t as CMTimeMBS = CMTimeMBS.MakeWithSeconds(5) // start at 5
dim d as CMTimeMBS = CMTimeMBS.MakeWithSeconds(10) // duration 10
dim r as CMTimeRangeMBS = CMTimeRangeMBS.Make(t,d)

Notes: A CMTimeRange is represented as two CMTime structs, one that specifies the start time of the range and another that specifies the duration of the range. A time range does not include the end time that would be calculated by adding the duration to the start time.
