CTransformOutputPin::Notify (Compact 2013)

  • Article

3/26/2014

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.
