MFCreatePresentationClock function
Creates the presentation clock. The presentation clock is used to schedule the time at which samples are rendered and to synchronize multiple streams.
Syntax
HRESULT MFCreatePresentationClock( IMFPresentationClock **ppPresentationClock );
Parameters
- ppPresentationClock
-
Receives a pointer to the clock's IMFPresentationClock interface. The caller must release the interface.
Return value
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
The caller must shut down the presentation clock by calling IMFShutdown::Shutdown on the clock.
Typically applications do not create the presentation clock. The Media Session automatically creates the presentation clock. To get a pointer to the presentation clock from the Media Session, call IMFMediaSession::GetClock.
