QML Camera Status Issue

dboostudio

Hi,

I'm using Qt 5.13.2 version.

I want to check cameraStatus for my mac desktop app to notice that camera really work or not(depends on permission).
I use QML Camera component for my app.

Camera is not webcam, it's built-in camera on Laptop

I checked cameraStatus work with Window OS.
But, in macOS, cameraStatus value shows no diffrence while I turning on/off permission of camera for Qt Creator and MyApp.

Also, I checked camera.availibilty , camera.cameraState

Here is my Code for check camera-status

        onCameraStatusChanged: {
            console.log("camera-Status " + cameraStatus)
            // Camera Status
            // 0 : UnavailableStatus , 1: UnloadedStatus, 2: LoadingStatus, 3: UnloadingStatus, 4: LoadedStatus
            // 5: StandbyStatus, 6: StartingStatus, 7: StoppingStatus, 8: ActiveStatus
            if(App.windows){
                if(cameraStatus < 4){
                    cameraConnection = false
                } else if (cameraStatus >= 4){
                    cameraConnection = true
                }
                pageMain.selectImageCamera(cameraConnection)
            }


            if(!pageMain.watch && !snapShotDone && cameraStatus === 8){
                console.log("camera-try to capture sanpshot")
                capture()
            }
        }

        onCameraStateChanged: {
            console.log("dboo : camera-state changed to : " + cameraState)

            console.log("dboo : camera-availibility" + camera.availability)
            console.log("dboo : camera-   aviliable = " + Camera.Available)
            console.log("dboo : camera-   busy = " + Camera.Busy)
            console.log("dboo : camera-   Unavailable = " + Camera.Unavailable)
            console.log("dboo : camera-   ResourceMissing = " + Camera.ResourceMissing)
            if(App.macosx) {
                switch(cameraState){
                case 1:
                    pageMain.selectImageCamera(false)
                    break
                case 2:
                    break
                case 3:
                    pageMain.selectImageCamera(true)
                }
            }
        }

Here is Log, whether camera-permission on/off, log shows same.

qml: camera-Status 4
qml: camera-Status 6
qml: dboo : camera-state changed to : 2
qml: dboo : camera-availibility0
qml: dboo : camera-   aviliable = 0
qml: dboo : camera-   busy = 2
qml: dboo : camera-   Unavailable = 1
qml: dboo : camera-   ResourceMissing = 3
qml: camera-Status 8
qml: camera-Status 7
qml: dboo : camera-state changed to : 1
qml: dboo : camera-availibility0
qml: dboo : camera-   aviliable = 0
qml: dboo : camera-   busy = 2
qml: dboo : camera-   Unavailable = 1
qml: dboo : camera-   ResourceMissing = 3

Is there another way to check camera availibilty on macOS?
Or, Is there right way to check macOS availibilty with above code?
