The 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.
Quality structure that contains the quality control message.
Returns an HRESULT value. Possible values include those shown in the following table.
|VFW_E_NOT_FOUND||Could not find an object to accept the message.|
This method calls the filter's CTransformFilter::AlterQuality method. If the filter does not handle the quality message, this method calls the CBaseInputPin::PassNotify method on the filter's input pin. The PassNotify method passes the quality message upstream (or to a custom quality manager, if one was installed).
