rtc screen share ( this is not webrtc because its for lan)

Stream your screen to any browser over LAN using WebRTC — no client installation required.

7xScreenShare is a lightweight, local-only screen sharing solution that streams your desktop to a browser via WebRTC. Designed for simplicity and speed, it eliminates the need for STUN/TURN servers, making it ideal for secure, low-latency screen sharing within a local network.

🚀 Project Goals

• Zero Client Setup: Enable screen viewing in any modern browser without additional software.

• LAN-Only Operation: Ensure all data remains within the local network for enhanced security and privacy.

• Low Latency: Utilize FFmpeg and WebRTC to achieve minimal delay in screen streaming.

• Cross-Platform Support: While initially tested on macOS, aim for compatibility with Linux and Windows.

• Modular Design: Facilitate easy integration and extension for various use cases.

📁 Project Structure

• main.go: The Go server that handles WebRTC signaling and serves the web interface.

• Makefile: Contains commands to start the FFmpeg capture and the Go server.

• index.html: The client-side interface to view the stream.

• README.md: Project documentation.

---

🔧 Configuration

• FFmpeg Capture Settings: Modify the make capture command in the Makefile to adjust resolution, frame rate, or input source.

• Server Port: The default server runs on port 8080. To change this, modify the main.go file accordingly.
