IMFClockStateSink::OnClockPause method (mfidl.h)

Called when the presentation clock pauses.

Syntax

HRESULT OnClockPause(
  [in] MFTIME hnsSystemTime
);

Parameters

[in] hnsSystemTime

The system time when the clock was paused, in 100-nanosecond units.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

When the presentation clock's IMFPresentationClock::Pause method is called, the clock notifies the presentation time source by calling the time source's OnClockPause method. This call occurs synchronously within the Pause method. If the time source returns an error from OnClockPause, the presentation clock's Pause method returns an error and the state change does not take place.

For any object that is not the presentation time source, the OnClockPause method is called asynchronously, after the state change is completed. In that case, the return value from this method is ignored.
