How to get the image buffer of videoOutput?

[stereoMatching]

Rectangle {
width: 320
height: 240

Camera{
id: camera
}

VideoOutput {
id: videoOutput

anchors.fill: parent
source: camera
}

GammaAdjust {
id: gammaAdjust

anchors.fill: videoOutput
source: videoOutput
gamma: 0.5
}
}


The source of the videoOutput come from camera
then process by the GammaAdjust
How could I get the image after process?
Any workaround?

What do you mean by "get" the image? If you want to do some more manipulation before displaying the frame, you can use ShaderEffectSource.
