more logs are needed, let it run for 1 minute then paste logs

you are trying to access a /dev/video11 device but it has not been mapped in to the frigate container

[sam-nicholls-bluefruit]

version: "3.9"
services:
frigate:
container_name: frigate
privileged: true # this may not be necessary for all setups
restart: unless-stopped
image: ghcr.io/blakeblackshear/frigate:stable
shm_size: "128mb" # update for your cameras based on calculation above
devices:
- /dev/video11:/dev/video11

here's my docker-compose.yml

[NickM-27]

okay, are you accessing a hardware device which is not an rtsp stream so your input args need to be changed

[NickM-27]

generally it is recommended to use go2rtc for this

[sam-nicholls-bluefruit]

thanks for your help, I don't suppose you could suggest an input arg or should I just go and try go2rtc?
