Streamlined Videochat

A lightweight, peer-to-peer video chat application built with WebRTC, Socket.io, and JavaScript. This project demonstrates a "serverless" video architecture where the backend only handles the initial handshake, and the video stream flows directly between users.

Features

• Real-time Video & Audio: High-quality, low-latency peer-to-peer streaming via WebRTC.
• Smart UI: Controls fade out automatically after 3 seconds of inactivity to maximize screen real estate. Tap or move the mouse to wake them.
• Draggable Self-View: A Picture-in-Picture style local video that can be dragged to any corner of the screen.
• Integrated Chat: Real-time text messaging with visual indicators.
• Mobile Ready: Touch-optimized controls, including a "Flip Camera" button for switching between front and back cameras on mobile devices.

Stack

• Frontend: HTML5, CSS3 (Glassmorphism UI), Vanilla JavaScript.
• Protocol: WebRTC (ICE, STUN).
• Communication: Socket.io Client.

Prerequisites

---

1. Signaling Server This frontend requires a backend signaling server to handle the initial connection handshake (Room joining, Session Description Protocol exchange, Interactive Connectivity Establishment candidates).

Note: The signaling server logic is hosted in a separate repository Ensure you have that the server is before running this client.

2. HTTPS (For Mobile) To test on mobile devices, this client must be served over HTTPS otherwise browser security policies will block camera and microphone access.

Usage

---

1. Open the app in two different browser windows or devices.
2. Enter the same Room Name (e.g., room99) in both instances.
3. Click Join.
4. Controls:
   • Tap/Click Screen: Hides/Shows the control bar.
   • Drag Video: Click and drag your local video preview to move it.
   • Chat: Click the bubble icon to open the text chat overlay.

Troubleshooting

• Camera/Mic Not Working: Ensure you are using HTTPS. Check browser permissions.
• Connection Fails: Verify your SIGNALING_SERVER_URL in script.js is correct and the server is running.
• "Room Full": The default signaling logic usually limits rooms to 2 peers. Try a different Room ID.
