    <h1> The Camera API </h1>

    <p>
        This paragraph is about the getUserMedia()-API, which is about to replace the deprecated camera-API.<br>
        The method <br>
        <code>
            navigator.mediaDevices.getUserMedia()
        </code>
        <br>
        asks for the users permission to access an input device like the camera. <br>
        If accepted, it returns a <i>Promise</i> which resolves into a <i>MediaStream</i>. The <i>MediaStream</i> can contain a video track, an audio track and various other tracks.<br>
        This stream can than be set as the <i>srcObject</i> of an video element in the HTML-Appliaction which the live stream of the selected input device. <br>
        Use it like this: <br>
        <code>
            var video = document.getElementById('video'); <br>
            <br>
        if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) { <br>
            navigator.mediaDevices.getUserMedia({ <br>
                video: true <br>
            }).then(function (stream) { <br>
                //video.src = window.URL.createObjectURL(stream); <br>
                video.srcObject = stream; <br>
                video.play(); <br>
            }); <br>
        } <br>
        </code>
        Try it out below! <br>
    </p>

    <video id="video" width="640" height="480" autoplay></video>

    <script>
        var video = document.getElementById('video');

        if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) {
            navigator.mediaDevices.getUserMedia({
                video: true
            }).then(function (stream) {
                video.srcObject = stream;
                video.play();
            });
        }
