Declaration

func CMSampleBufferGetOutputDecodeTimeStamp(_ sbuf: CMSampleBuffer) -> CMTime

Parameters

• sbuf:

  The CMSampleBuffer being interrogated.

Return Value

The output decode timestamp of the CMSampleBuffer or kCMTimeInvalid if there is an error.

For consistency with CMSampleBufferGetOutputPresentationTimeStamp(_:), this function calculates the returned value as:

OutputPresentationTimeStamp + ((DecodeTimeStamp - PresentationTimeStamp) / SpeedMultiplier)
