IAMVideoProcAmp interface (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The IAMVideoProcAmp interface adjusts the qualities of an incoming video signal, such as brightness, contrast, hue, saturation, gamma, and sharpness.
The WDM Video Capture filter exposes this interface if the hardware supports image adjustment.
Inheritance
The IAMVideoProcAmp interface inherits from the IUnknown interface. IAMVideoProcAmp also has these types of members:
