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
The default base class implementation returns E_FAIL.
Remarks
This member function must be overridden to accept notifications. It is typically overridden to implement this method on the output pin because quality-control messages are passed upstream. The CTransformOutputPin::Notifymember function is one example of how this member function is overridden to pass quality-control messages to the next filter upstream.
