PROJECT README

README

Visualizer Stream turns a media catalog into a controllable live visual system rather than a conventional video player.

A FastAPI control plane owns normalization, analysis, catalog state, queueing, autoplay, render-node coordination, and RTP streaming while authoritative music-state updates guide selection. Show mode, audience policy, resilient standby preparation, and strict media-source boundaries make the engine suitable for long-running installations and live sets.
