StreamWatchdog (watchdog.py) — polls mediamtx /v3/paths/list каждые N sec.
Если ожидаемый path missing > threshold → emit MQTT event stream_lost +
показывает text overlay 'OFFLINE'. При восстановлении — stream_restored +
remove overlay.
Config:
watchdog:
enabled: true
mediamtx_api_url: http://cuda-grid-mediamtx:9997
poll_interval_sec: 5.0
lost_threshold_sec: 15.0
paths:
- mediamtx_path: live-audio
instance: tv_grid
label: Audio
overlay_when_lost: true
httpx добавлен в Dockerfile.
Сегодняшний incident (audio sidecar потерял connection с mediamtx →
pipeline restart loop) — watchdog обнаружит missing live-audio через
15 sec + покажет TV-side warning. Manual restart audio sidecar still
needed (watchdog auto-restart — Phase 2).

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) |
