The Stop method stops the filter.
Returns an HRESULT value. Possible values include those shown in the following table.
|S_FALSE||Transition is not complete.|
|S_OK||Success. Transition is complete.|
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.
