WebRTC Video Calling

Project Overview

This project implements a WebRTC-based video calling application where users can create and join video call rooms for peer-to-peer (P2P) communication. The application uses Socket.IO for signaling and WebRTC to establish direct, real-time connections between users. By entering a unique room name and email, users can connect with others, and once two users enter the same room, they can initiate a video call.

Key Features

• Room Creation: Allows users to create a unique room for video calls.
• Real-Time Signaling: Utilizes Socket.IO for signaling, room management, and message exchange between users.
• Peer-to-Peer Communication: Establishes direct P2P video calls using WebRTC after signaling.
• Secure Communication: The video call is encrypted, ensuring secure communication between users.
• End-to-End Video Call: Users can see and hear each other in real-time.

Technologies Used

• WebRTC - Peer-to-peer real-time video and audio communication.
• Socket.IO - Real-time communication for signaling and room management.
• Node.js - Backend runtime for the signaling server.
• Express.js - Web framework to handle routing and middleware.
• HTML5/CSS3/JavaScript - Frontend technologies for the user interface and WebRTC logic.

How to Use

1. Create a Room:

   • Enter your email and a unique room name.
   • Click Join Room to create and enter the room.

2. Share the Room:

   • After joining the room, you can share the room link with the second person.
   • The second person needs to enter the same room name and their email.

3. Start the Call:

   • Once both users are in the room, the video call will be automatically initiated.

4. End the Call:

   • Either user can click the End Call button or close the browser window to end the call.

WebRTC Flow (P2P Connection)

1. User 1 enters the room, and a signaling message is sent to the server.
2. User 2 enters the same room, and the signaling messages are exchanged via Socket.IO.
3. ICE Candidates are gathered by WebRTC and exchanged to establish the peer-to-peer connection.
4. Once the signaling and ICE candidates are exchanged, the P2P connection is established, and both users can see and hear each other.

Setup and Installation

1. Clone the Repository
