CBaseRenderer.SendEndOfStream method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
If end-of-stream was reached, the SendEndOfStream method schedules an EC_COMPLETE event for the filter graph manager.
Syntax
virtual HRESULT SendEndOfStream();
Parameters
This method has no parameters.
Return value
Returns an HRESULT value. Possible values include those in the following table.
| Return code | Description |
|---|---|
|
The filter graph manager is not accepting event notifications. |
|
Success. |
Remarks
The filter might receive an end-of-stream notification before the current sample's stop time. If so, the filter should wait before posting an EC_COMPLETE notification to the filter graph manager.
Therefore:
- If the filter has received an early end-of-stream (EOS) notification, this method schedules a timer event. When the timer event is activated, the filter posts the EC_COMPLETE event.
- If the filter has received an EOS notification that was not early, this method posts the EC_COMPLETE event immediately.
- If the filter does not have any pending EOS notification, the method returns without doing anything.
The timer callback method is CBaseRenderer::TimerCallback. To deliver the EC_COMPLETE event, the filter calls the CBaseRenderer::NotifyEndOfStream method.
