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 Value
Returns an HRESULT value. Possible values include those shown in the following table.
| Value | Description |
| 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).
