IMFStreamSink::Flush method (mfidl.h)

  • Article

Causes the stream sink to drop any samples that it has received and has not rendered yet.

Syntax

HRESULT Flush();

Return value

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

Return code Description
S_OK
 The method succeeded.
MF_E_NOT_INITIALIZED
 The stream sink has not been initialized yet. You might need to set a media type.
MF_E_SHUTDOWN
 The media sink's Shutdown method has been called.
MF_E_STREAMSINK_REMOVED
 This stream was removed from the media sink and is no longer valid.

Remarks

If any samples are still queued from previous calls to the IMFStreamSink::ProcessSample method, the media sink immediately discards them, without processing them. This can cause a glitch in the rendered output. The running state of the sink (running, paused, or stopped) does not change.

Any pending marker events from the IMFStreamSink::PlaceMarker method are dispatched immediately, with the status code E_ABORT.

This method is synchronous. It does not return until the sink has discarded all pending samples.
