Overview

This is the backend for the video conferencing project using Mediasoup. It handles WebRTC media routing, socket signaling, room management, and real-time communication. Built with Node.js, Express.js, and Socket.IO, it ensures a scalable and efficient backend infrastructure for many-to-many video conferencing.

Features

• Manages Mediasoup Workers, Routers, and Transports
• Handles WebRTC Producer & Consumer Streams
• Supports up to 5 Active Speakers per Room
• Real-time Signaling with Socket.IO
• Efficient SFU-based Media Streaming
• Room Creation and Management

Tech Stack

• Node.js - Backend runtime environment
• Express.js - Lightweight web framework
• Socket.IO - WebSocket-based real-time communication
• Mediasoup - WebRTC Selective Forwarding Unit (SFU)

Installation

Prerequisites

Ensure you have the following installed:

• Node.js (Latest LTS recommended)
• NPM or Yarn

   npm start

How It Works

1. Users Join a Room
   • They connect via WebRTC and are assigned producer/consumer roles.
2. Mediasoup Manages Media Routing
   • Optimizes video/audio streams for efficient bandwidth usage.
3. Socket.IO Handles Communication
   • Provides real-time updates between clients.
4. Active Speaker Detection
   • Dynamically updates the UI to display the top 5 active speakers.
