Experimental support for WebRTC has landed in the Chrome developer channel. The feature is available for testing when users launch the browser with the --enable-media-stream flag. We did some hands-on testing and used some of the new JavaScript APIs to make an HTML5 photo booth.
WebRTC is a proposed set of Web standards for real-time communication. It is intended to eventually enable native standards-based audio and video conferencing in Web applications. It is based on technology that Google obtained in its 2010 acquisition of Global IP Solutions and subsequently released under a permissive open source software license.
