Represents a presentation clock, which is used to schedule when samples are rendered and to synchronize multiple streams.
The IMFPresentationClock interface inherits from IMFClock. IMFPresentationClock also has these types of members:
To create a new instance of the presentation clock, call the MFCreatePresentationClock function. The presentation clock must have a time source, which is an object that provides the clock times. For example, the audio renderer is a time source that uses the sound card to drive the clock. Time sources expose the IMFPresentationTimeSource interface. To set the time source, call SetTimeSource. The presentation clock does not begin running until the Start method is called.
To get the presentation clock from the Media Session, call IMFMediaSession::GetClock.
