Instance Property

startTime

The timestamp for the first timed data sample in the asset.

Declaration

@property(nonatomic, readwrite) NSTimeInterval startTime;

Discussion

Timed data in an asset is clamped to the start and end times—requesting sample data for a time sample before the start time returns the sample data at the start time.

If the asset does not contain timed information, this property’s value is zero.
