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.
