WebRTC Video Call Basics: A Beginner's Guide

WebRTC is a free and open-source technology that enables real-time communication between web browsers and mobile applications using simple APIs. It allows developers to directly embed real-time communication capabilities into web and mobile applications, including voice and video calling, chat, file sharing, and screen sharing, without requiring any plugins or external software. WebRTC utilizes a combination of media codecs, encryption, and network protocols to provide secure and efficient real-time communication. It consists of two primary components: media channels for exchanging audio and video data between peers, and data channels for the exchange of arbitrary data between peers. With WebRTC, developers can build various real-time communication applications such as video conferencing platforms, voice and video calling apps, live streaming services, collaborative whiteboards, online gaming platforms with voice chat, and customer support systems with screen sharing capabilities.
