CTransformOutputPin.Notify method

The Notify method notifies the pin that a quality change is requested. This method implements the IQualityControl::Notify method.

Syntax


HRESULT Notify(
   IBaseFilter *pSelf,
   Quality     q
);

Parameters

pSelf

Pointer to the IBaseFilter interface of the filter that delivered the quality control message.

q

Quality structure that contains the quality control message.

Return codeDescription
S_OK

Success.

VFW_E_NOT_FOUND

Could not find an object to accept the message.

 

Remarks

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).
