Passes a quality-control notification to the appropriate sink.
Syntax
HRESULT PassNotify( Quality q ); |
Parameters
- q
-
Quality-control notification object.
Return Value
Returns VFW_E_NOT_FOUND if no quality sink is set and the upstream filter does not support the IQualityControlinterface.
Otherwise, returns the HRESULTvalue resulting from notifying the sink or the upstream filter.
Remarks
Output pins receive quality-control notifications and, if possible, filters act on them to degrade appropriately. Often, filters cannot respond to the notifications; in this case the notification should be passed to the quality-control sink or, by default, upstream to the next filter.
The PassNotifymember function is called from the CTransformOutputPin::Notifymember function when a notification requires passing. The Qualitystructure passed is the one that the output pin received.
