IMediaFilter::Stop method (strmif.h)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
The Stop method stops the filter.
Syntax
HRESULT Stop();
Return value
Returns an HRESULT value. Possible values include those shown in the following table.
| Return code | Description |
|---|---|
|
Transition is not complete. |
|
Success. Transition is complete. |
Remarks
When a filter is stopped, it does not process or deliver any samples, and it rejects samples from upstream filters.
The state transition might be asynchronous. If the method returns before the transition completes, the return value is S_FALSE.
This method always sets the filter's state to State_Stopped, even if the method returns an error code.
