The WebRTC codelab shows how to use all three APIs to build a simple app for video chat and file sharing. RTCDataChannel: To see this in action, see WebRTC samples to check out one of the data-channel demos. This app uses adapter.js, a JavaScript shim maintained by Google with help from the WebRTC community, to abstract away browser differences and spec changes. RTCPeerConnection: For a simple demo and a fully functional video-chat app, see WebRTC samples Peer connectionĪnd appr.tc, respectively. GetUserMedia: For demos and code, see WebRTC samples or try Chris Wilson's amazing examples that use getUserMedia as input for web audio. MediaStream (also known as getUserMedia)Īll three APIs are supported on mobile and desktop by Chrome, Safari, Firefox, Edge, and Opera.WebRTC has also been integrated with WebKitGTK+ and Qt native apps. WebRTC is used in various apps, such as Google Meet.

The guiding principles of the WebRTC project are that its APIs should be open source, free, standardized, built into web browsers, and more efficient than existing technologies. It's often difficult to persuade people to install plugins in the first place!

Plugins are difficult to deploy, debug, troubleshoot, test, and maintain-and may require licensing and integration with complex, expensive technology.

Downloading, installing, and updating plugins is complex, error prone, and annoying.

These included Skype, Facebook, and Hangouts.

Many web services used RTC, but needed downloads, native apps, or plugins.

WebRTC implemented open standards for real-time, plugin-free video, audio, and data communication. In May 2011, Ericsson built the first implementation of WebRTC. Google open sourced the technologies developed by GIPS and engaged with relevant standards bodies at the Internet Engineering Task Force (IETF) and World Wide Web Consortium (W3C) to ensure industry consensus. Google bought GIPS, a company that developed many components required for RTC, such as codecs and echo cancellation techniques. Gmail video chat became popular in 2008 and, in 2011, Google introduced Hangouts, which uses Talk (as did Gmail). Integrating RTC technology with existing content, data, and services has been difficult and time-consuming, particularly on the web. Historically, RTC has been corporate and complex, requiring expensive audio and video technologies to be licensed or developed in house. Without it, you're limited in your ability to innovate and develop new ways for people to interact. RTC should be as natural in a web app as entering text in a text input. One of the last major challenges for the web is to enable human communication through voice and video: real-time communication or RTC for short.

To learn how WebRTC uses servers for signaling, and firewall and NAT traversal, see the code and console logs from appr.tc.

To learn about the RTCPeerConnection API, see the following example and RTCPeerConnection.If you haven't used the getUserMedia API, see Capture audio and video in HTML5.To get an overview of WebRTC, watch the following Google I/O video or view these slides: Haven't got time to read this article or only want code? Open the URL displayed at the end of the page in a new tab or, better still, on a different computer.Click Join to join a chat room and let the app use your webcam.A good place to start is the simple video chat app at appr.tc: Want to try it out? WebRTC is available on desktop and mobile in Google Chrome, Safari, Firefox, and Opera. Imagine it was easy to add video chat and peer-to-peer data sharing to your web app. Imagine a world where your phone, TV, and computer could communicate on a common platform. WebRTC is a new front in the long war for an open and unencumbered web.īrendan Eich, inventor of JavaScript Real-time communication without plugins
