Declaration
func samplePresentationTime(forTrackTime trackTime: CMTime) -> CMTimeParameters
- trackTime:
The track time for which to request the sample presentation time.
Return Value
The sample presentation time corresponding to the specified time; otherwise invalid if the time is out of range.
Discussion
Apple discourages using this method in iOS 15, tvOS 15, macOS 12, and watchOS 8 or later. Load a sample presentation time asynchronously using loadSamplePresentationTime(forTrackTime:completionHandler:) instead.
