[BUG] libcamera apps cannot detect camera(imx219) when running in a docker container using balenaOS

[rahul-thakoor]

Describe the bug Any utility in libcamera-apps is not able to detect the camera. All exit with

INFO Camera camera_manager.cpp:293 libcamera v0.0.0+3406-e96d0201
No cameras available!

Here is the config.txt content:

camera_auto_detect=1
dtoverlay=vc4-kms-v3d,cma-512
gpu_mem=256
disable_touchscreen=1
max_framebuffers=2
avoid_warnings=1
disable_splash=1
dtparam=i2c_arm=on
dtparam=spi=on
dtparam=audio=on

I have tried several configs, e.g

camera_auto_detect=0
dtoverlay=vc4-kms-v3d
max_framebuffers=2
dtoverlay=imx219

[naushir]

Firstly, does your setup work correctly in a standard Raspberry Pi OS?

I'm not familiar with balenaOS, can you provide some further details? Do the apps work when running outside a docker environment?

[rahul-thakoor]

Hi, Yes, my setup works with Raspberry Pi OS 2022-01-28

BalenaOS is a minimal linux OS with services needed to run Docker on boards like the Raspberry Pi.

I am able to use le legacy camera stack in a container environment. libcamera-apps on the other hand do not work.

I can try to run the app using docker on Raspberry Pi OS.

Are there known issues in running the app without X11? I am using libcamera-apps-lite and also tried with --no-preview option.

Thanks

[naushir]

Are there known issues in running the app without X11? I am using libcamera-apps-lite and also tried with --no-preview option.

libcamera-apps run fine without X11. I doubt your problems are related to preview either. The error thrown says there are no cameras detected, but from the logs you posted, a camera has clearly been probed. This is most likely due to the BalenaOS/docker environment problem. Perhaps there is a permissions issue trying to access the /dev/video device nodes? I'm afraid I am not going to be able to help much since I am not familiar with this environment.

[kbingham]

The required devices will need to be passed through into the container. This include /dev/v4l-subdev /dev/video and /dev/media*

Those devices will have to have the correct permissions or group to be able to access those devices too.

[rahul-thakoor]

thanks @naushir @kbingham

i am running a privileged container and the hostOS has

cat /etc/group | grep -i video
video:x:44:

I am also using

    group_add:
      - video

for the service.

in the container, the root user is part of the video group.

 root@4deb13f05908:/usr/src/app# cat /etc/group | grep -i video
video:x:44:root

The container has access to all devices in /dev:

ls -l /dev/video*
crw-rw---- 1 root video 81, 12 Mar  4 11:47 /dev/video0

Not sure what is missing at this point 🤔

[kbingham]

Can you run your libcamera hello command again but prefix with LIBCAMERA_LOG_LEVELS=*:0 And paste the output please?

[kbingham]

I am actually suspecting it will be due to udev or lack thereof in the container.

Enforcing sysfs enumeration might identify or resolve it

raspberrypi.cpp:1114 Unable to acquire a Unicam instance looks like the cause?

also thanks for the debugging tip :)

[rahul-thakoor]

I also have udev enabled in the container with the same result. are there any specific udev rules to be added?

[rahul-thakoor]

btw, I just found this https://forums.raspberrypi.com/viewtopic.php?t=325755

That looks like the starting point for debug. No unicam means no camera.

Can you access /dev/media* within the docker container? From you last set of logs, it seems maybe not.

This is my output for LIBCAMERA_LOG_LEVELS=*:0 libcamera-hello --list-cameras showing libcamera enumerating /dev/media* which seems to be missing from your logs:

Ok - that really makes me think this is an issue with UDev, ... as the DeviceEnumerator is run by udev by default. If udev is available but doesn't return anything you can end up with ... no devices.

Check in: https://git.libcamera.org/libcamera/libcamera.git/tree/src/libcamera/device_enumerator.cpp#n141

std::unique_ptr<DeviceEnumerator> DeviceEnumerator::create()
{
    std::unique_ptr<DeviceEnumerator> enumerator;

#ifdef HAVE_LIBUDEV
    enumerator = std::make_unique<DeviceEnumeratorUdev>();
    if (!enumerator->init())
        return enumerator;
#endif

    /*
     * Either udev is not available or udev initialization failed. Fall back
     * on the sysfs enumerator.
     */
    enumerator = std::make_unique<DeviceEnumeratorSysfs>();
    if (!enumerator->init())
        return enumerator;

    return nullptr;
}

Can you try removing the code between HAVE_LIBUDEV and rebuilding libcamera? (or otherwise forcing the enumerator to be constructed from the DeviceEnumeratorSysfs.

If this finds it, then we might want to make it easier to fallback to sysfs enumeration at runtime... or otherwise establish how to get libudev to operate in a container.

[kbingham]

https://forums.docker.com/t/docker-not-passing-udev-events-to-container-even-after-using-net-host/92394/2

Seems to indicate you might need to pass /run/udev/control through as a volume to the container.

or : -v /run/udev:/run/udev:ro

from https://stackoverflow.com/questions/41753218/udevadm-does-not-show-all-attributes-inside-a-docker-container

[rahul-thakoor]

Hey @kbingham i managed to get it to work. it was indeed related to udev.

i ran udevadm control --reload in the container

You need to make sure your on the latest kernel updates from raspberry pi

[bugsyb]

Thank you @kbingham. I did hold on with pi kernel upgrades as there was recently a problem with libcamera apps which prohibited the two from working hence kept version from default installation (which worked). Not sure though why docker container would be complaining about it.

[kbingham]

Does it work outside the container?

[meawoppl]

For me at least (RasPi 4b + IMX477), I got to this page because I didn't have the camera_auto_detect flag set.

To do this you either have to set the flag in the config.txt BEFORE THE FIRST BOOT. Or use the balena bashboard to set it on the device. Navigate the menus: Device Configuration >> Custom Configuration >> Add Custom Configuration Name: BALENA_HOST_CONFIG_camera_auto_detect Value: 1

Or set it fleetwide in a menu above that with a similar flow.

Dockerfile:

FROM arm64v8/ros:humble-ros-base

RUN apt-get update && apt-get install -y v4l-utils

# Runtime volume will be created here for libcam caching
RUN mkdir -p /opt/installs/src
COPY install_libcam_deps.sh   /opt/installs/src/
RUN cd /opt/installs/src && ./install_libcam_deps.sh

# Runtime volume will be created here for build caching
WORKDIR /opt/colcon_ws/

Note that it's important, as said above, that you detect the correct cameras in config.txt as this loads the correct device tree overlays, as I understand it. If you're running raspbian as a host, you should be able to see the cameras on the host. Then, the connections mentioned above while running should be enough, I think.

For instance, my run is:

docker run -it -v ${PWD}/colcon_ws:/opt/colcon_ws -v ${PWD}/installs/:/opt/installs/src/ --privileged --network=host -v /dev/:/dev/ --env UDEV=1 --device /dev:/dev -v /run/udev:/run/udev:ro  libcam-ros /bin/bash

My run command is a combination of the advice above with my specific setup - unsure if every volume/udev instruction is necessary, but it works for me.
