IMFPresentationClock::Pause method (mfidl.h)

Pauses the presentation clock. While the clock is paused, the clock time does not advance, and the clock's IMFPresentationClock::GetTime returns the time at which the clock was paused.

Syntax

HRESULT Pause();

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Remarks

This method is valid when the clock is running. It is not valid when the clock is paused or stopped.

The presentation clock initiates the state change by calling IMFClockStateSink::OnClockPause on the clock's time source. This call is made synchronously. If it fails, the state change does not occur. If the call succeeds, the state changes, and the clock notifies the other state-change subscribers by calling their OnClockPause methods. These calls are made asynchronously.
