To access the camera when it is supported by the hardware and Qt Multimedia, use the Camera type and its associated types to control the camera's capture behavior, exposure, flash, focus, and image processing settings. A simple use of the camera to show a viewfinder looks like the following code:

import QtQuick 2.3
import QtMultimedia 5.0

Item {
    width: 640
    height: 480

    Camera {
        id: camera
    }

    VideoOutput {
        source: camera
        anchors.fill: parent
    }
}

In short, the Camera type acts like a source for the video just as a MediaPlayer instance does.

The Camera type provides a few properties to control its behavior. They are:

The types associated with these fields can't be instantiated directly.

To have the camera take a picture, specify the imageCapture property and invoke its capture method, as follows:

import QtQuick 2.3
import QtMultimedia 5.0

Item {
    width: 640
    height: 360

    Camera {
        id: camera

        imageCapture {
            onImageCaptured: {
                // Show the preview in an Image
                photoPreview.source = preview
            }
        }
    }

    VideoOutput {
        source: camera
        focus : visible // to receive focus and capture key events when visible
        width: 320
  height: 180
  anchors.top: parent.top
  anchors.horizontalCenter: parent.horizontalCenter

        MouseArea {
            anchors.fill: parent;
            onClicked: camera.imageCapture.capture();
        }
    }

    Image {
        id: photoPreview
        width: 320
        height: 180
        anchors.bottom: parent.bottom
        anchors.horizontalCenter: parent.horizontalCenter
    }
}

Here, the camera displays its viewfinder in the top VideoOutput item and has an Image item at the bottom to display the captured image. When you touch the viewfinder, the QML invokes the capture method of imageCapture, which is part of Camera, capturing the image and updating the bottom image.

The imageCapture property of the Camera item also has a capturedImagePath property, which is a string to the path where the last captured image is stored.

Recording works in a similar manner; you specify the attributes of the recording, such as the desired codec in the videoRecording property, and then invoke its record and stop methods to start and stop recording. The resulting video will be stored at the location indicated by the property's actualLocation field.
