I write QML code to select an appropriate CameraFormat for my application; in my case, I want to avoid the overhead of cameras which produce their output as JPEG. Consider the following QML snippet:

Item {
    CaptureSession {
        id: captureSession
        camera: Camera {
            id: camera
            cameraFormat: {
                let videoFormats = Object.values(camera.cameraDevice.videoFormats)
                // Failure: VideoFrameFormat.Format_Jpeg is not defined; use the number 29 instead.
                videoFormats = videoFormats.filter(videoFormat => videoFormat.pixelFormat !== VideoFrameFormat.Format_Jpeg)
                return videoFormats[0]
}
}
}
}

Note that the enum VideoFrameFormat.Format_Jpeg is not defined, causing this code to fail. Therefore, providing this enum would improve the quality of QML code.
