Getting Started with WebRTC

By: Rob Manson

Overview of this book

WebRTC delivers web-based real-time communication and is set to revolutionize our view of what the Web really is. Streaming audio and video from browser to browser, as well as opening raw access to the camera and microphone, is already creating a whole new dynamic web. WebRTC also introduces real-time data channels that will allow interaction with dynamic data feeds from sensors and other devices. This really is a great time to be a web developer! Getting Started with WebRTC provides all of the practical information you need to quickly understand what WebRTC is, how it works, and how you can add it to your own web applications. It includes clear working examples designed to help you get started building your own WebRTC-enabled applications right away. Getting Started with WebRTC will guide you through the process of creating your own WebRTC application that can be applied in a number of different real-world situations, using well documented and clearly explained code examples. You will learn how to quickly and easily create a practical peer-to-peer video chat application, an audio only call option, and how a Web-Socket-based signaling server can also be used to enable real-time text-based chat. You will also be shown how this same server and application structure can easily be extended to include simple drag-and-drop file sharing with transfer updates and thumbnail previews.

Extending this example into a Chatroulette app


Now that you have a working application that connects two users in a peer-to-peer video call, you can easily extend this in a number of ways. One option is to change the setup and signaling flow so that callees are connected to random callers just like the video Chatroulette applications that have sprung up all across the Internet. Have a look at this Google search, https://www.google.com/search?q=video+chat+roulette.

To implement this type of functionality, you only need to make two simple changes.

First, each browser that connects to the web page can randomly be allocated as either a caller or a callee, removing the need for the caller to send a link with call_token to the callee. In this new application, users just visit the web page and are automatically entered into either the caller or callee scenario.

Second, update the signaling server so that when a callee joins, the signaling server loops through the webrtc_discussions object looking...
