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 |
|---|---|
|
The method succeeded. |
|
The stream sink has not been initialized yet. You might need to set a media type. |
|
The media sink's Shutdown method has been called. |
|
This stream was removed from the media sink and is no longer valid.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.
