WebRTC Screen Share with Openfire

Chrome version 26 stable and Firefox (Nightly build) now support full desktop screen sharing. In Chrome, you have to enable “Enable screen capture support in getUserMedia()” with the chrome://flags URL.

As the desktop screen is treated as a video device, you only have to make a change to the getUserMedia method for video and your existing application will work with no further changes. As an example, I only made the following change to my webrtc video example and now it allows two users to share their desktop screens

navigator.webkitGetUserMedia(
    {video:{mandatory: {chromeMediaSource: 'screen'}}},
    this.onUserMediaSuccess.bind(this),
    this.onUserMediaError.bind(this)
);

To see it in action, just click on this URL https://webrtc.free-solutions.org:8443/webrtc/screen.html from two different PCs. Register with two different user names (no spaces or special characters).

It is hosted by the very good kind and generous folks at free-solutions.org

Just confirmed it works for me with Chrome 27

I am using Chrome 27 and have no option " Enable screen capture support in getUserMedia()" in the chrome://flags

How can I set this in Chrome??

chromeMediaSource: 'screen'

without modifying the HTML/JS source.

I like to capture screen with jappix-openfire plugin,

Sorry, you have to modify code with Javascript/HTML to make that happen

I use firefox 22 in Linux, and get this error:

webkitRTCPeerConnection not supported by this browser

you have to switch webrtc on with firefox flags/settings
