CTransformOutputPin::Notify (Windows Embedded CE 6.0)
1/6/2010
Notifies the recipient that a quality change is requested.
Syntax
HRESULT Notify(
IBaseFilter* pSelf,
Quality q
);
Parameters
- pSelf
Pointer to the filter that is sending the quality notification.
- q
Quality notification structure.
Return Value
Default base class implementation returns E_FAIL.
Remarks
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.
