IVideoProcAmp Interface

This topic applies only to Windows XP Service Pack 2 and later.

The IVideoProcAmp interface controls the image adjustment (ProcAmp) settings on a capture device.

This interface may be exposed by one or more nodes in a capture filter. It is not exposed at the level of the filter itself. To enumerate the nodes, query the filter for the IKsTopologyInfo interface. For each node, call IKsTopologyInfo::get_NodeType to get the node type. The IVideoProcAmp interface is exposed by nodes of type KSNODETYPE_VIDEO_PROCESSING. Get the interface pointer by calling IKsTopologyInfo::CreateNodeInstance with the value IID_IVideoProcAmp.

This interface corresponds to the PROPSETID_VIDCAP_VIDEOPROCAMP property set, which is documented in the Windows DDK.

In addition to the methods inherited from IUnknown, the IVideoProcAmp interface exposes the following methods.
