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.

Summary


You should now have a clear understanding of how to create a fully working application that connects two users in a WebRTC-based peer-to-peer video call. You should be able to utilize the MediaStream and RTCPeerConnection APIs in real world scenarios and understand how these different components work together in a living application.

You should be able to set up a web server that handles the initial process of connecting two users and set up a signaling server that manages the setup of the video call. You should understand in detail how the caller's browser initiates the JSEP offer and how the callee's browser responds with an answer. You should have a clear knowledge of how the local and remote video streams are connected to and displayed in the web page, how these streams can be processed to create filters and other special effects, and how this example application can easily be extended.

In the next chapters, we will explore how this application can be simplified down to just an...
