Properties
brightness
“brightness” gfloat
The color brightness, expressed as a float value. Range is -1.0 to 1.0. Default value is 0.0 and represents no modification.
Flags : Read / Write
Default value : 0
contrast
“contrast” gfloat
The color contrast, expressed as a float value. Range is 0.0 to 2.0. Default value is 1.0 and represents no modification.
Flags : Read / Write
Default value : 1
crop-bottom
“crop-bottom” guint
The number of pixels to crop at bottom.
Flags : Read / Write
Default value : 0
crop-left
“crop-left” guint
The number of pixels to crop at left.
Flags : Read / Write
Default value : 0
crop-right
“crop-right” guint
The number of pixels to crop at right.
Flags : Read / Write
Default value : 0
crop-top
“crop-top” guint
The number of pixels to crop at top.
Flags : Read / Write
Default value : 0
deinterlace-method
“deinterlace-method” GstVaapiDeinterlaceMethod *
This selects the deinterlacing method to apply.
Flags : Read / Write
Default value : bob (1)
deinterlace-mode
“deinterlace-mode” Vaapi-deinterlace-mode *
This selects whether the deinterlacing should always be applied or if they should only be applied on content that has the "interlaced" flag on the caps.
Flags : Read / Write
Default value : auto (0)
denoise
“denoise” gfloat
The level of noise reduction to apply.
Flags : Read / Write
Default value : 0
force-aspect-ratio
“force-aspect-ratio” gboolean
When enabled, scaling respects video aspect ratio; when disabled, the video is distorted to fit the width and height properties.
Flags : Read / Write

Selects whether HDR tone mapping should not be applied or if it should be only applied on content that has the HDR meta on the caps.
Flags : Read / Write
Default value : auto (0)
height
“height” guint
The forced output height in pixels. If set to zero, the height is calculated from the width if aspect ration is preserved, or inherited from the sink caps height

Flags : Read / Write
Default value : 0
skin-tone-enhancement
“skin-tone-enhancement” gboolean
Apply the skin tone enhancement algorithm.
Flags : Read / Write
Default value : false
skin-tone-enhancement-level
“skin-tone-enhancement-level” guint
Apply the skin tone enhancement algorithm with specified level
Flags : Read / Write
Default value : 3
video-direction
“video-direction” GstVideoOrientationMethod *
The video-direction to use, expressed as an enum value. See GstVideoDirection.
Flags : Read / Write
Default value : identity (0)
width
“width” guint
The forced output width in pixels. If set to zero, the width is calculated from the height if aspect ration is preserved, or inherited from the sink caps width
Flags : Read / Write
Default value : 0
