Camera functionality not working as expected in Qt 6

Re: QCamera switches not to Active State

I have this simple implementation for Camera in qml, but when I try to get the active state of the camera, it gives false and if I try to set the active to true by default, my application crashes. Is there anything wrong with my code. I am migrating my project from Qt 5.15 to Qt 6.4 and have gone through the documentation. My project runs the camera fine on Qt 5.15 but not in Qt 6.4.

I get the below output upon printing default media device:
QCameraDevice(\\?\usb#vid_0c45&pid_6d14&mi_00#6&6d2bd98&0&0000#{e5323777-f976-4f5b-9b55-b94699c46e44}\global, Integrated Webcam, false, UnspecifiedPosition, )

Item {
    id: captureImage
    height: 300
    width: 300

    MediaDevices {
        id: mediaDevices
    }

    CaptureSession {
        camera: Camera {
            id: camera
            cameraDevice: mediaDevices.defaultVideoInput
            whiteBalanceMode: Camera.WhiteBalanceManual
            focusMode: Camera.FocusModeAutoNear
        }
        imageCapture: ImageCapture {
            id: imageCapture
        }
        videoOutput: VideoOutput {
            id: videoOutput
        }
    }
}

@SGaist Can I please have a response on this? I have tried the exact same way as per QML Camera Example but it didn't run. The example project on the other hand runs fine.

Hi,

Do you mean that the example provided with Qt 6 is working properly but not your code ?

HackSaw

@SGaist Yes, you are correct.

SGaist

How are you doing things differently from the example ?
