Remarks
To receive state-change notifications from the presentation clock, implement this interface and call IMFPresentationClock::AddClockStateSink on the presentation clock.
This interface must be implemented by:
- Presentation time sources. The presentation clock uses this interface to request change states from the time source.
- Media sinks. Media sinks use this interface to get notifications when the presentation clock changes.
