Such information can be termed as metadata. The important thing is to realize that a lot of information needs to be exchanged before a direct connection can be set-up.

Key data used to establish secure connectionsĭon’t worry if you do not understand what the above information represents.

Media metadata, such as codecs, codec settings, bandwidth, and media types that will be sent by a peer.

Session-control messages - used to open or close communication.

Network data, such as a peer’s IP address and port as seen by the outside world.

If there is any other peer available for communication.

RTCDataChannel: stream data between users.īefore the two peers can start communicating with each other, they need to know a lot of information about each other like.

RTCPeerConnection: stream audio and video between users.

getUserMedia(): capture audio and video.

The most important APIs that we will use in this tutorial series are - click links to see demos WebRTC consists of several interrelated APIs and protocols which work together to achieve Real Time Communication. You can find the list of all the browsers supporting WebRTC here. ) have implemented WebRTC framework and have exposed WebRTC’s APIs for the developers, it is better to confirm that your browser version supports it. Though most of the major browsers (like Chrome, Firefox etc.

It is open-sourced and its source code is freely available at. WebRTC automatically handles all of these concerns under the hood.This technology doesn’t need any plugins or third-party software.

With WebRTC, all of this comes built-in into the browser out-of-the-box. To build an application (that requires peer-to-peer communication) from scratch without WebRTC, you would need a wealth of frameworks and libraries dealing with typical issues like With WebRTC, the role of the server is limited to just helping the two peers discover each other and set up a direct connection. It enables peer-to-peer communication without any server in between and allows the exchange of audio, video, and data between the connected peers. WebRTC stands for Web Real-Time Communication. This is why we will have to use WebRTC - an open-source framework providing web browsers and mobile applications with real-time communication via simple APIs. Such communication is possible if we eliminate the server from between. Hence, for video conferencing, we require Real-Time Communication between the browsers. Imagine yourself talking to someone who receives your voice 5 secs later. It will be extremely difficult to talk to someone using such an application. However, in the case of a video conferencing application, this delay is significant.

Even if this delay is (say) 5 secs, we would still be able to use this chatting application. This delay hardly affects the utility of the chatting app.

But having a server in the middle results in a delay in communication between the browsers. In a simple chatting web app, when two browsers need to send messages to each other, they typically need a server in between for coordination and passing the messages. Fundamentalsīefore we begin to develop such a web app, we need to understand how an e-conferencing application is different from a simple chatting web app.

Also, this series will definitely help all those developers who would like to learn how to build applications such as real-time advertising, multiplayer games, live broadcasting, e-learning, to name a few, where the action takes place in real time. The aim of this tutorial series is to teach how to develop such a video-conferencing web application. From parties to business meetings, these video conferencing platforms are now commonplace for virtually everyone. The ongoing COVID-19 situation has many more people working from home than ever before and companies using web conferencing as their primary means of communication between employees and clients.Īnd with much of the world on lockdown with social distancing measures enforced, even spending time with family and friends is now largely restricted to online video calls. If you weren’t familiar with web video-conferencing platforms and apps before the Covid-19 pandemic, we bet you know all about them now and must have used one of them.
