Notify method notifies the pin that a quality change is requested. This method implements the IQualityControl::Notify method.
HRESULT Notify( IBaseFilter *pSelf, Quality q );
Pointer to the IBaseFilter interface of the filter that delivered the quality-control message.
Specifies a Quality structure that contains the quality-control message.
The base class returns E_NOTIMPL.
Output pins should override this method to accept quality-control messages.
If an external quality manager was installed (see CBasePin::SetSink), pass the message to that quality manager. Otherwise, the filter should handle the message itself, or pass the message upstream. For more information, see Quality-Control Management.
