WebRTC Streaming Demo

A Rust WebRTC server that captures video and audio from your browser's camera/microphone and streams it back in real-time. Demonstrates bidirectional WebRTC media streaming with a clean Rust backend.

Features

• Real-time video/audio capture from browser
• WebRTC peer connection with automatic SDP exchange
• VP8 video codec with RTCP feedback (PLI)
• Opus audio codec
• Embedded web client served from the Rust binary
• Async architecture using Tokio

Quick Start

1. Install Rust

2. Run the server:

cargo run --release

3. Open http://localhost:8080 in your browser

4. Allow camera and microphone access when prompted

5. Your video stream will appear after the WebRTC connection is established

Architecture

Browser                          Rust Server
   |                                  |
   |-- getUserMedia() --------------->|
   |                                  |
   |<-- SDP Offer ------------------->|
   |                                  |
   |--- RTP Video/Audio ------------->|
   |                                  |
   |<-- RTP Video/Audio (loopback) ---|

The server:

1. Serves the HTML client at /
2. Handles SDP offer/answer exchange at /local
3. Receives media tracks from the browser
4. Loops them back to demonstrate bidirectional streaming
