CVideoTransformFilter::AlterQuality (Compact 2013)
3/26/2014
Receives a quality-control notification and provides an opportunity to alter the quality of the media stream.
Syntax
virtual HRESULT AlterQuality(
Quality q
);
Parameters
- q
Quality-control notification message.
Return Value
This member function returns E_FAIL by default.
Remarks
This member function overrides the CTransformFilter::AlterQuality member function.
It is called by the CTransformOutputPin::Notify member function before calling the CBaseInputPin::PassNotify member function to pass the quality control message upstream.
This function sets the m_itrLate data member to the value Quality structure's Late member so the filter can determine whether to skip frames.
It returns E_FAIL so that the renderer downstream will continue to handle quality control.
