go2rtc.service (NUEVO)

# /etc/systemd/system/go2rtc.service [Unit] Description=go2rtc media server After=network.target [Service] Type=simple User=video ExecStart=/usr/local/bin/go2rtc \ -config /etc/go2rtc/go2rtc.yaml Restart=on-failure RestartSec=5 StandardOutput=journal StandardError=journal [Install] WantedBy=multi-user.target
sudo systemctl daemon-reload sudo systemctl enable --now go2rtc.service
Añadir After=go2rtc.service mumble-server.service en oasis.service para que el proxy arranque tras los upstreams.

Docker — Integración

# docker-compose.yml (fragmento) services: snh: image: snh-bookworm:latest devices: - /dev/video0:/dev/video0 # cámara ports: - "3000:3000" # Oasis (único puerto público) volumes: - mumble-data:/var/lib/mumble - ./go2rtc.yaml:/etc/go2rtc/go2rtc.yaml:ro
No exponer :1984 ni :64738 en ports. Solo :3000 sale al exterior.
