Notifies the recipient that a quality change is requested.
HRESULT Notify( IBaseFilter *pSelf, Quality q );
Pointer to the filter that is sending the quality notification.
Quality notification structure.
Default base class implementation returns E_FAIL.
This member function implements the IQualityControl::Notify method and overrides the CBasePin::Notify member function. It calls the CTransformFilter::AlterQuality member function to determine if the filter can do something to adjust the quality of the media stream (such as discarding samples). If that member function returns S_FALSE, it calls the CBaseInputPin::PassNotify member function, which passes the notification to the upstream filter after verifying that it is connected upstream.
