Unsolved QMultimeida CameraRecorder not recording. (Erro: Failed to get the video control)

[Fortune]

Hi guys. I'm a beginner with qml and am already getting frustrated and discouraged. I'm having problems with getting my webcam to work with qml! Am not sure what am doing wrong but here is my code.

import QtQuick 2.0
import QtQuick.Controls 1.3
import QtMultimedia 5.0

Item {
    id:root
    Button{
        id:recordButton
        x: 0
        y: parent.height-height
        width: parent.width/2
        height: 80
        text:"Record"
        onClicked:{
            
            camera.videoRecorder.record();
            console.log(camera.videoRecorder.recorderStatus==CameraRecorder.UnavailableStatus)
            
        }
    }
    Button{
        id:stopButton
        x: parent.width/2
        y: parent.height-height
        width: parent.width/2
        height: 80
        text:"Stop"
        onClicked: {
            camera.videoRecorder.stop();
            console.log()
            console.log()
            
            console.log("output location: " +camera.videoRecorder.outputLocation)
            console.log("actual location: " +camera.videoRecorder.actualLocation)
        }
    }
    
    VideoOutput{
        id:preview
        width: parent.width
        height: parent.height-stopButton.height
        source:camera
        anchors.top:parent.top;
        anchors.right: parent.right
        anchors.left: parent.left
        anchors.bottom: stopButton.top
        Camera{
            id:camera
            videoRecorder.audioEncodingMode: CameraRecorder.ConstantBitRateEncoding
            videoRecorder.audioBitRate: 128000
            videoRecorder.mediaContainer: "mp4"
            videoRecorder {
                resolution: "640x480"
                frameRate: 30
            }
        }
    }
    
}

here is my application output windows

When I click on "Record" I get this

"QML debugging is enabled. Only use this in a safe environment.
Failed to get the video control"

and when I click on stop, I get this

"qml:
qml:
qml: output location:
qml: actual location: "

Note that my webcam works fine. I use it many times to record videos of myself and I also use it for skype so it definitely not a hardware problem. Please help me
