https://labs.ericsson.com/apis/web-real-time-communication/ Through emerging web standards, it will soon be possible to build web applications with support for real-time voice and video communication without the need for plug-ins. By downloading and running this browser, experimentation can be done with these new features.

1. Web Real-Time
Communication
A labs.ericsson.com API

2. Web Real-Time communication
› Get early access to experimental browser features for
real-time voice and video communication (Web-RTC)
› Early experimentation
– Download our browser
– Build your own “Web-RTC”-
enabled web app
– Provide API feedback

3. WHY Web-RTC?
› Write a web application with native HTML support for
conversational voice/video
– No plug-ins needed
› Prepare your existing web app for emerging standards
– Work ongoing in WhatWG, W3C, IETF and WebKit

4. Main Features
› Download our browser
– Early access to Web-RTC APIs
– Experimental WebKit (GTK+) implementation
› Point-to-point media over UDP
– No server relay, low latency
› Getting started
– Sample code to help you get started
– Demo application (https://webrtc.labs.ericsson.net/)
› NOTE! Only tested on Ubuntu 11.04
