CVideoTransformFilter::AlterQuality (Windows Embedded CE 6.0)

1/6/2010

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.

Requirements

Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
