CTransformOutputPin::Notify
Microsoft DirectShow 9.0 |
CTransformOutputPin::Notify
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).
Requirements
** Header:** Declared in Transfrm.h; include Streams.h.
** Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
