Peer-to-Peer Video Conferencing

Project Overview

This project implements a real-time Peer-to-Peer (P2P) Video Conferencing application using WebRTC. It enables users to communicate via video, audio, and text chat, making it an ideal solution for remote collaboration. The system is designed with a Node.js backend for signaling and a JavaScript frontend, hosted on Vercel and AWS.

Features

🔹 Real-Time Communication

• Video & Audio Streaming: Direct P2P connections for low-latency communication.
• Text Chat: Built-in messaging system with usernames.
• Media Controls: Mute/unmute audio and toggle video during calls.

🔹 User Controls

• Create & Join Rooms: Generate unique room IDs and invite participants.
• Error Handling: Clear error messages for missing inputs or invalid rooms.
• Pause & Resume: Manage media streams dynamically.

🔹 Network & Security

• STUN Servers: Uses stun.l.google.com:19302 for NAT traversal.
• Secure HTTPS Deployment: Enables camera and microphone permissions.

How to Use

1️⃣ Creating a Room

1. Enter a username.
2. Click Create Room to generate a unique Room ID.
3. Share the Room ID with others to join.

2️⃣ Joining a Room
