How to get the resolution of the Camera in QML

lalvishnu12

Hi,

I am using the Qml Camera element for capturing camera output and using the VideoOutput for diplaying it.
How can I find the resolution of the Camera in Qml ?

@lalvishnu12 According to the documentation, the property resolution holds the resolution/size of the image to be captured. If empty, the system chooses the appropriate resolution.

+ info

Maybe you could try to get the value of that property when you start the camera.

Thanks for the reply.

But it is showing only QSize(-1,-1) when I console it.

@lalvishnu12 Hi,

I've been working with some examples, and I afraid you must set the resolution or you'll get that size if you request it.

I suppose you know how to set the resolution, but anyway, here you have a piece of code:

 Camera {
    id: camera

    imageCapture {
        onImageCaptured: {
            console.log(vRecorder.resolution)
        }
    }

    videoRecorder {
        id: vRecorder
        resolution: "320x240"
        frameRate: 30
    }
}

Thank you for the reply.
I tried setting the resolution property of the CameraCapture and the console printed the given value. But the resolution of the image captured was in the camera's default resolution.

I didn't tried it in the VideoRecorder. I will try it.
