Janus WebRTC Media Server <\/b>is a powerful and open-source server-side software that is specifically built for the purpose of real-time communication in web apps<\/a>. In this article, you’ll learn the steps to build a video calling app using this server along with WebRTC protocol. <\/span><\/p>\n\n\n\n

Before we get started, it is important to know the basics of Janus, WebRTC and also understand how to build video call apps.<\/span><\/p>\n\n\n\n

So, I’ll break down the following sections into 3 parts<\/em><\/strong><\/span><\/p>\n\n\n\n

    WebRTC plays a vital role in enabling real-time communication in any app these days. Do you think browser APIs are enough to implement WebRTC? Not at all!<\/span><\/p>\n\n\n\n

    Sometimes, complex apps require more than just browser APIs. This is where most developers use Janus server. This server does all that you need to connect web apps with communication protocols.<\/span><\/p>\n\n\n\n

    <\/span>What is Janus Webrtc Server?<\/b><\/span><\/h2>\n\n\n\n

    Janus is an open-source WebRTC server developed by Meetecho. The core reason where Janus stands out from other servers is that it offers a blank canvas besides functionalities like <\/span>video conferencing<\/span><\/a> and <\/span>online multi-streaming<\/span><\/a>. This gives developers the freedom to build their video call app with careful focus on the actual business requirements.<\/span><\/p>\n\n\n\n
