How do I access navigator.getUserMedia()?

Question

I am currently running Chrome 11 and trying to access getUserMedia for HTML5 native audio and video stream support but I am getting an error saying that navigator.getUserMedia is undefined. If it's not supported, how do I access it or do I need to wait until Chrome incorporates it?

This is the the code I was using to test getUserMedia which I found

 <h1>Snapshot Kiosk</h1>
 <section id="splash">
  <p id="errorMessage">Loading...</p>
 </section>
 <section id="app" hidden>
  <p><video id="monitor" autoplay></video> <canvas id="photo"></canvas>
  <p><input type=button value="&#x1F4F7;" onclick="snapshot()">
 </section>
 <script>
  navigator.getUserMedia('video user', gotStream, noStream);
  var video = document.getElementById('monitor');
  var canvas = document.getElementById('photo');
  function gotStream(stream) {
    video.src = URL.getObjectURL(stream);
    video.onerror = function () {
      stream.stop();
      noStream();
    }
    video.onloadedmetadata = function () {
      canvas.width = video.videoWidth;
      canvas.height = video.videoHeight;
      document.getElementById('splash').hidden = true;
      document.getElementById('app').hidden = false;
    }
  }
  function noStream() {
    document.getElementById('errorMessage').textContent = 'No camera available.';
  }
  function snapshot() {
    canvas.getContext('2d').drawImage(video, 0, 0);
  }
 </script>

The latest opera desktop build has support for getUserMedia() See here: http://labs.opera.com/news/2011/10/19/

It's just a waiting game for other browsers to implement this. Now that opera has support, the other should soon follow.

Since last night (3 May 2012) getUserMedia() in Chrome Canary takes an object not a string.

To try it out, you can run the following code from the console on any page (like this one) with a video element:

navigator.webkitGetUserMedia(
  {"video": true, "audio": true}, 
  function(s){
    document.querySelector('video').src = 
      window.webkitURL.createObjectURL(s);
  }, 
  function(e){console.log(e);}
);
