VideoProcAmpProperty enumeration (strmif.h)

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 VideoProcAmpProperty enumeration specifies video properties on a video capture device.

Syntax

typedef enum tagVideoProcAmpProperty {
  VideoProcAmp_Brightness = 0,
  VideoProcAmp_Contrast,
  VideoProcAmp_Hue,
  VideoProcAmp_Saturation,
  VideoProcAmp_Sharpness,
  VideoProcAmp_Gamma,
  VideoProcAmp_ColorEnable,
  VideoProcAmp_WhiteBalance,
  VideoProcAmp_BacklightCompensation,
  VideoProcAmp_Gain
} VideoProcAmpProperty;

Constants

 
VideoProcAmp_Brightness
Value: 0
Specifies the brightness, also called the black level. For NTSC, the value is expressed in IRE units * 100. For non-NTSC sources, the units are arbitrary, with zero representing blanking and 10,000 representing pure white. Values range from –10,000 to 10,000.
VideoProcAmp_Contrast
Specifies the contrast, expressed as gain factor * 100. Values range from zero to 10,000.
VideoProcAmp_Hue
Specifies the hue, in degrees * 100. Values range from -180,000 to 180,000 (-180 to +180 degrees).
VideoProcAmp_Saturation
Specifies the saturation. Values range from 0 to 10,000.
VideoProcAmp_Sharpness
Specifies the sharpness. Values range from 0 to 100.
VideoProcAmp_Gamma
Specifies the gamma, as gamma * 100. Values range from 1 to 500.
VideoProcAmp_ColorEnable
Specifies the color enable setting. The possible values are 0 (off) and 1 (on).
VideoProcAmp_WhiteBalance
Specifies the white balance, as a color temperature in degrees Kelvin. The range of values depends on the device.
VideoProcAmp_BacklightCompensation
Specifies the backlight compensation setting. Possible values are 0 (off) and 1 (on).
VideoProcAmp_Gain
Specifies the gain adjustment. Zero is normal. Positive values are brighter and negative values are darker. The range of values depends on the device.
