I have a just added WebRTC audio/video support to OfChat to confirm that the proposed WebRTC transport for Jingle actually works.

OfChat is a web client for Openfire implemented as a Chrome extension. I am not releasing the WebRTC code until the the next release of Chrome which will use JSEP instead of ROAP.

UPDATE

I have attached the latest OfChat Chrome extension (ver 0.0.8) with support for WebRTC using the Jingle WebRTC Transport proposal. Sadly, the proposal is to be withdrawn, so this might be incompatible with anything else in a few months time. See posting below for requirements. It is all in HTML and JavaScript, so finds where Chrome installs it to see source code.
