    <script language="javascript" type="text/javascript">
    function onVideoFail(e) {
        console.log('webcam fail!', e);
      };
 
    function hasGetUserMedia() {
      // Note: Opera is unprefixed.
      return !!(navigator.getUserMedia || navigator.webkitGetUserMedia ||
                navigator.mozGetUserMedia || navigator.msGetUserMedia);
    }
 
    if (hasGetUserMedia()) {
      // Good to go!
    } else {
      alert('getUserMedia() is not supported in your browser');
    }
 
    window.URL = window.URL || window.webkitURL;
    navigator.getUserMedia  = navigator.getUserMedia ||
                             navigator.webkitGetUserMedia ||
                              navigator.mozGetUserMedia ||
                               navigator.msGetUserMedia;
 
    var video = document.querySelector('video');
    var streamRecorder;
    var webcamstream;
 
    if (navigator.getUserMedia) {
      navigator.getUserMedia({audio: true, video: true}, function(stream) {
        video.src = window.URL.createObjectURL(stream);
        webcamstream = stream;
    //  streamrecorder = webcamstream.record();
      }, onVideoFail);
    } else {
        alert ('failed');
    }
 
    function startRecording() {
        streamRecorder = webcamstream.record();
        setTimeout(stopRecording, 10000);
    }
    function stopRecording() {
        streamRecorder.getRecordedData(postVideoToServer);
    }
    function postVideoToServer(videoblob) {
 
        var data = {};
        data.video = videoblob;
        data.metadata = 'test metadata';
        data.action = "upload_video";
        jQuery.post("uploadvideo.php", data, onUploadSuccess);
    }
    function onUploadSuccess() {
        alert ('video uploaded');
    }
 
    </script>
 

    <video autoplay></video>
    <div id="webcamcontrols">
        <button class="recordbutton" onclick="startRecording();">RECORD</button>
