# Video Streams

The VideoOutput element is not limited to be used in combination with a MediaPlayer element. It can also be used with various video sources to display video streams.

For instance, we can use the VideoOutput to display the live video stream of the user's Camera. To do so, we will combine it with two components: Camera and CaptureSession.

import QtQuick
import QtMultimedia

Window {
    width: 1024
    height: 768
    visible: true

    CaptureSession {
        id: captureSession
        camera: Camera {}
        videoOutput: output

    VideoOutput {
        id: output
        anchors.fill: parent

    Component.onCompleted: captureSession.camera.start()

The CaptureSession component provides a simple way to read a camera stream, capture still images or record videos.

As the MediaPlayer component, the CaptureSession element provides a videoOuput attribute. We can thus use this attribute to configure our own visual component.

Finally, when the application is loaded, we can start the camera recording:

Component.onCompleted: captureSession.camera.start()


Depending on your operating system, this application may require sensitive access permission(s). If you run this sample application using the qml binary, those permissions will be requested automatically.

However, if you run it as an independant program you may need to request those permissions first (e.g.: under MacOS, you would need a dedicated .plist file bundled with your application).
