FrigateCameraMapping +priority +main_cam_index — для auto-layout decision.
FrigateBridgeCfg.auto_layout flag — toggle через REST.
Logic (FrigateBridge._update_auto_layout):
0 active cameras → quad (default overview)
1+ active → single, main_cam = highest priority active
Equal priority → first active wins (deterministic)
Dispatcher.set_main_cam — ZMQ streamselect@main_cam map <index>
Config.main_cam_filter_target = "streamselect@main_cam"
REST:
GET /auto-layout/{instance} — current toggle state
POST /auto-layout/{instance} — { enabled: bool }
при включении сразу применяет
UI:
+ checkbox "auto" в Layout card — toggleAuto() hits POST /auto-layout
Live verified: enable → immediately picks layout=single, main=gate_lpr
(priority=10, highest active). Visual confirms gate_lpr full screen.

cuda-grid-controller
Control-plane sidecar для vf_cuda_grid FFmpeg filter. Transforms
MQTT / HTTP REST commands от Home Assistant / Node-RED / custom apps
в FFmpeg process_command через ZeroMQ. Publishes state + events наружу
для bidirectional integration.
Статус: Phase 3 work-in-progress — basic skeleton + HA Discovery + ZMQ command bridge. Phase 4+ добавит overlays, audio orchestration.
Что умеет (Phase 3)
- ✅ MQTT subscribe
cuda_grid/cmd/<instance>/layout/set→ ZMQ send → FFmpeg layout switch - ✅ MQTT publish
cuda_grid/state/<instance>/layout(retained) +cuda_grid/event/.../layout_switched - ✅ HA MQTT Discovery —
select.layout+sensor.current_layout+binary_sensor.onlineper instance - ✅ HTTP REST API:
/health,/layouts,/state,POST /layout/{instance}/set - ✅ Multi-instance (несколько FFmpeg pipelines с разными ZMQ endpoints)
- ✅ Auto-reconnect MQTT, LWT для availability tracking
Использование
pip install -e .
export MQTT_USERNAME=mqtt
export MQTT_PASSWORD=secret
cuda-grid-controller --config examples/controller.yaml
FFmpeg side — как подключить cuda_grid + zmq filter
ffmpeg -i cam1.mp4 -i cam2.mp4 -i cam3.mp4 -i cam4.mp4 \
-filter_complex "
[0:v][1:v][2:v][3:v]cuda_grid=layout=quad,
zmq=bind_address=tcp\\\\://127.0.0.1\\\\:5555
" \
-c:v h264_nvenc out.mp4
(После этого controller с zmq_endpoint: tcp://127.0.0.1:5555 сможет
переключать layout командой cuda_grid@... layout six_grid.)
HA dashboard
После startup controller'а — в Home Assistant появятся entities:
select.cuda_grid_<instance>_layout— dropdown с layoutssensor.cuda_grid_<instance>_current_layout— текущий выбранныйbinary_sensor.cuda_grid_controller_online— online/offline
Roadmap
| Phase | Что |
|---|---|
| 3 (this) | Basic skeleton + HA Discovery + ZMQ bridge для layout switching |
| 4 | Overlay API (rect/text/icon через side data) |
| 5 | Rich overlays (image/dim/graph/chat) + privacy filtering |
| 6 | Audio orchestration (state machine, domofon use case) |
