Receives a quality-control notification and provides an opportunity to alter the quality of the media stream.
virtual HRESULT AlterQuality( Quality q );
Parameters
- q
- Quality-control notification message.
Return Values
This member function returns E_FAIL by default.
Remarks
This member function overrides the CTransformFilter::AlterQualitymember function. It is called by the CTransformOutputPin::Notifymember function before calling the CBaseInputPin::PassNotifymember function to pass the quality control message upstream. This function sets the m_itrLatedata member to the value Qualitystructure's Latemember so that the filter can determine whether to skip frames. It returns E_FAIL so that the renderer downstream will continue to handle quality control.
