How to design a custom videoOutput?

  • The videoOutput I mean is
    Rectangle {
    width: 320
    height: 240

            id: camera
        VideoOutput {
            id: videoOutput
            anchors.fill: parent
            source: camera
        GammaAdjust {
            id: gammaAdjust
            anchors.fill: videoOutput
            source: videoOutput
            gamma: 0.5


    How could design the videoOutput by myself?
    Maybe this is the fastest and easiest way to save the
    image after postprocessing,thanks

  • I tried grab() function before, but this solution can't work on android,it will crash
    I find through the document and exmaples but have no clue of how to get the buffer of videoOutput, safe the result after postprocess or create my own videoOutput
