<section id="blurb">
<p>This demo shows ways to use constraints and statistics in WebRTC applications.</p>
<p>Set camera constraints, and click <strong>Get media</strong> to (re)open the camera with these included. Click <strong>Connect</strong> to create a (local) peer connection. The RTCPeerConnection objects <code>localPeerConnection</code> and <code>remotePeerConnection</code> can be inspected from the console.</p>
<p>Setting a value to zero will remove that constraint. </p>
<p>The lefthand video shows the output of <code>getUserMedia()</code>; on the right is the video after being passed through the peer connection. The transmission bitrate is displayed below the righthand video.</p>
