RCWeb Camera Control App

The RCWeb Camera Control App (app/camera-control) is the broadcaster half of a dedicated RCWeb camera streaming pair. It follows the Asymmetric Pattern: a controller captures the local camera and microphone, then sends the media directly to every camera-view client in the same room over WebRTC.

What it does

• Device selection: Lets the broadcaster choose a camera and microphone source from the browser's available devices.
• One-to-many streaming: Creates one WebRTC connection per viewer so the same source can be shared with everyone watching the room.
• Local preview: Shows the broadcaster a live preview plus simple audio/video status chips before and during transmission.
• Room invite flow: Generates a viewer URL for the current RCWeb room so it is easy to open or share the matching camera-view page.

How it works

• RCWeb signaling: script.js uses rc.sendFunctionCall(...) to announce broadcaster presence, accept stream requests from viewers, and exchange WebRTC offers, answers, and ICE candidates.
• Broadcaster-owned negotiation: The controller always creates the WebRTC offers, which keeps the controller/viewer handshake simpler than a symmetric mesh app.
• Track replacement: Switching camera or microphone sources updates the existing peer connections by replacing the sender tracks and renegotiating.
• Room cleanup: Viewer cards are removed when RCWeb reports that the corresponding client has left the room or closed the page.

Notes

• Browser access to camera and microphone typically requires HTTPS or localhost.
• The app uses STUN servers for ICE discovery, but it does not include a TURN relay.
