5b — audio source switching:
AudioSourceCfg list + audio_filter_target в InstanceCfg
CommandDispatcher._audio_set → ZMQ astreamselect@as map <index>
REST: GET /audio/{inst}, POST /audio/{inst}/set
MQTT: cuda_grid/cmd/<inst>/audio/set <source_name>
5c — intercom ducking:
music_volume_target / intercom_volume_target / music_ducked_volume в InstanceCfg
CommandDispatcher._intercom_set → 2× ZMQ volume@music/@intercom commands
REST: POST /intercom/{inst}/start (music↓ + intercom↑) + /end (restore)
MQTT: cuda_grid/cmd/<inst>/intercom/start|end
6 — dynamic overlays (charts/chats):
dynamic_overlays.py: ChartCfg/ChatCfg + DynamicRenderer
PIL rendering: line chart + scrolling text list
Async loops пишут PNG в icon_dir + invalidate filter cache via reload_icon ZMQ
MQTT subscriptions для real data (charts: numeric topic, chats: text topic)
Demo: chart sine wave если data_topic=null
Wired в __main__.py + mqtt_loop dispatch
+ ZMQ client asyncio.Lock — REQ socket strict send/recv pattern требует
serialize requests (overlay/audio/intercom concurrent ломали "Operation
cannot be accomplished in current state")
+ Pillow в Dockerfile (для PIL render)

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) |
