Presentation Commander — Server
NDI matrix for live events
What it does
The master control application for a presentation room: a real-time NDI video matrix router, a layered scene compositor and a presenter-notes hub, as an Electron desktop app. It pairs with the client that runs on each presentation laptop.
Sources come from live mDNS NDI discovery rather than a typed-in list, and a layer backed by a real network source shows a live video preview rendered from actual received frames, not a placeholder box.
- Source pool from live _ndi._tcp.local discovery, plus web sources
- Layered scene compositor — drag to reposition, drag a corner to resize, toggle visibility
- Matrix inspector: route any output to any source or to a full composited scene
- Control Deck showing presenter notes and slide position from every connected client
- A button-grid control surface for scene recall, blackout, next and previous, and notes to stage
- A JSON-RPC automation API on port 9700 — the same command path the buttons themselves use
Where it stands
In development, tagged at v1.0.1. Verified against the shipped demo data and driven over its own automation API — the video tour is the real application, not a mockup — but running without a presentation laptop paired to it, and never on a live show.
