Notifies the recipient that a quality change is requested.
HRESULT Notify( IBaseFilter * pSelf, Quality q );
Parameters
- pSelf
- Pointer to the filter that is sending the quality notification.
- q
- Quality notification structure.
Return Values
Default base class implementation returns E_FAIL.
Remarks
This member function implements the IQualityControl::Notifymethod and overrides the CBasePin::Notifymember function. It calls the CTransformFilter::AlterQualitymember 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::PassNotifymember function, which passes the notification to the upstream filter after verifying that it is connected upstream.
