Phase 4a deliverable (no filter rendering yet — это Phase 4b).
End-to-end pipeline: HA/HTTP/MQTT → controller → ZMQ → FFmpeg (logged).
Modules:
- overlays.py — 7 discriminated union types через pydantic:
rect, text, icon, image, dim, graph, chat. Normalized coords (0.0-1.0),
optional cell binding, z_order, opacity, visible.
- state.py — overlay storage per instance (CRUD: add/remove/update/get/clear)
- dispatch.py — overlay.add/remove/clear actions:
- parses JSON payload в Overlay через TypeAdapter
- serializes to ZMQ string: "<id> <type> <full-json>"
- sends via FFmpeg process_command (filter will парсить в Phase 4b)
- updates state + publishes events (overlay_added, overlay_removed, overlays_cleared)
- http_api.py — REST endpoints:
- POST /overlay/{inst}/add (body = Overlay JSON, returns id)
- GET /overlay/{inst} — list all
- DELETE /overlay/{inst}/{id} — single
- DELETE /overlay/{inst} — clear all
- PATCH /overlay/{inst}/{id} — update
- mqtt_loop.py — already subscribes cuda_grid/cmd/<inst>/+/+; teper handles
overlay/add (JSON payload), overlay/remove (id), overlay/clear
- frigate_bridge.py — FrigateBridge skeleton:
- subscribe frigate/+/motion + frigate/events
- mapping camera_name → target_instance + cell index
- Phase 4a: log received events (rendering в Phase 4b)
- config.py — frigate: optional section
- examples/controller.yaml — frigate mappings для 4 наших камер
State management:
- ControllerState.add/remove/update/get/clear_overlay (asyncio.Lock guarded)
- InstanceState.overlays: dict[str, Overlay]
- IDs generated via uuid4()[:8]
Phase 4a limitations:
- Filter side ничего не рендерит (just logs ZMQ commands)
- Frigate bridge принимает events но не auto-generates overlays
- HA Discovery не имеет overlay-specific entities (overlays через REST API)
Phase 4b: filter-side AVFrame side data + CUDA kernels (rect first, NPP-based,
потом text via freetype atlas, потом icon sprite blit).
