ations.</p> |
| 26 <p>Set camera constraints, and click <strong>Get media</strong> to (re)ope
n the camera with these included. Click <strong>Connect</strong> to create a (lo
cal) peer connection. The RTCPeerConnection objects <code>localPeerConnection</c
ode> and <code>remotePeerConnection</code> can be inspected from the console.</p

| 27 <p>Setting a value to zero will remove that constraint. </p> |
| 28 <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 trans
mission bitrate is displayed below the righthand video.</p> |
