Raspberry pi camera support with docker on OpenWrt

[Neirop]

Question

I'm trying to use a Raspberry pi camera on a Raspberry pi 5 in OpenWrt with the docker container bluenviron/mediamtx:latest-rpi.

I installed these relevant packages:

kmod-camera-bcm2835
kmod-codec-bcm2835
kmod-isp-bcm2835
kmod-vchiq-mmal-bcm2835
kmod-drm-vc4
kmod-vc-sm-cma
kmod-vchiq-mmal-bcm2835
v4l2camera

I added to /boot/config.txt:

dtoverlay=vc4-kms-v3d-pi5
start_x=1
dtparam=i2c=on
camera_auto_detect=1
dtoverlay=imx219,cam1

But the camera still can't be found:

[0:00:38.939159420] [17]  INFO Camera camera_manager.cpp:325 libcamera v0.3.2+27-7330f29b-dirty (2024-12-02T23:04:17UTC)
2025/01/25 23:41:14 ERR [path cam] [RPI Camera source] camera_create(): selected camera is not available

What am I missing?
