WebRTC is the central standard for the development of web-based real-time communication applications, delivering the capability of seamlessly integrating peer-to-peer audio and video communication. The WebRTC protocol removes the typical barriers to web-based real-time communication by providing an array of enabling APIs which overcome variances in browser capability and platform, simplifying accessibility for developers, and end users.

This video course will equip you with the understanding to quickly develop a complete WebRTC application, ready to be integrated into your own web application. If you’re interested in creating a video application with WebRTC , this video delivers a strong example application which you can use, whilst laying the foundation for you to develop more complex instances in the future.

This courses opens with an introduction to WebRTC, placing it in context of similar technologies in the web environment, before diving into an exploration of key WebRTC APIs.

After detailing the main API utilities, we’ll examine various signalling approaches before designing two servers, one for serving our example, and another one for providing signalling. At this point, we'll put all the pieces together to create a fully functional, real-time communication application.

The final section of this video course focuses on debugging and improving WebRTC applications treating other frameworks and developer tools which can be used to this end, with modern techniques employed by experienced developers.

By the time you complete this video course, you will understand the fundamentals of WebRTC and its array of powerful APIs, with the ability to establish real-time video conferencing functionality over the web, with whoever you want.

Introducing the full outline from the course.

The Course Overview

A short introduction to WebRTC, its chronology, and some things we can do with it.

What’s WebRTC?

We will analyze how WebRTC is different from older technologies such as Flash and Java, and the pros and cons of web apps versus desktop apps.

WebRTC Versus Existing Technologies

WebRTC requires a compatible web browser. A nice source code editor is recommended.

Getting Your Programming Environment Ready
4 Lectures 16:50

Introducing the basic elements of the API that will make communication using WebRTC possible.

Preview 03:21

Checking a basic example of calling the GetUserMedia method on Chrome, keeping in mind that some browsers may not have the functionality or the standard notation.

Using the getUserMedia API

Another example referring to the way the implied peers tell each other which capabilities, parameters, and other sets can be used.

Using the PeerConnection Method

SDPs and other pieces of information about sessions are needed to go through firewalls and NAT routers, which translate between private and public IPs.

Using the Session Description Protocol
4 Lectures 13:36

WebRTC doesn’t provide signaling by itself—is this a good thing or a bad one?

Preview 03:11

SIPoWS, XMPPoWS, and JSONoWS are the different protocols that can work with WebRTC, providing signaling.

Knowing the Various Signaling Approaches

We come back to the reasons we gave for using signaling (connecting the peers before negotiation), and we explain how signaling solves the problem.

Need of Signaling Protocol

We will use an example called signalmaster, available at the GitHub repository:

Programming a Very Simple NodeJS Signaling Server
Putting It All Together — Your First Application
3 Lectures 13:04

Introducing the example. Node.js and as tools for the example. Getting our media and creating a room.

Preview 06:15

Joining a room. Sending SDPs as offer and answer. Then, negotiating ICE candidates.

Receiving a WebRTC Session

We will establish a connection and discuss changes for a generic solution, and introducing DataChannels along the way.

Establishing Our First Session
Debugging and Improving Our Application
3 Lectures 18:06

Introducing the main tools available for debugging WebRTC apps.

Preview 04:08
