The cameras I deal with are shown as /dev/video*. Can you check whether they are listed here:

v4l2-ctl --list-devices

It may be related to RPi MMAL camera detection with legacy camera stack vs modern camera stack. Currently we use vcgencmd get_camera to detect the RPi camera module, and I'm not sure whether this works when using KMS + modern camera driver stack with V4L2 and libcamera. I guess you have camera_auto_detect=1 and dtoverlay=vc4-kms-v3d in your /boot/config.txt?

and yes those commands are in the /boot/config.txt

I have done some more reading, this thread is helpful.

I'm not sure how such infrared camera is commonly provided. E.g. based on v4l2-ctl --list-devices output it seems like /dev/media1 can also be obtained from /dev/video0, but /dev/media0 is associated with a larger number of /dev/video* devices, so not sure if/how this may work.

However, you added it as MMAL camera, right? In this case vcgencmd get_camera is used, and this only works with the legacy camera stack where the output needs to start with supported=1 detected=1. Since you have the modern camera stack enabled (which is perfectly fine, in general, the default on modern RPi OS), this isn't recognised. For this we need to implement libcamera utilities support. I hence adjusted this issue to reflect it being a feature request for supporting libcamera MMAL cameras.

But it would be interesting to know whether the cameras an be accessed via V4L2. It should show the large list of devices from your v4l2-ctl --list-devices output. Probably you can try whether any of those is working, probably even /dev/media0 and /dev/media1?

... https://www.raspberrypi.com/documentation/accessories/camera.html#v4l2-drivers

Actually to me it seems like MMAL is generally the legacy driver, V4L2 the one used with libcamera. Probably the libcamera- utilities are not necessary at all. The question is whether motion is able to catch the camera stream with modern stack, e.g.: #1857

Related issue on motion project: Motion-Project/motion#1434
Seems like currently motion is not able to handle the modern RPi camera stack. Solution would be to either switch to legacy stack, or providing the stream with other software, like mjpg-streamer, then adding it as local network camera.

I have not added it as an MMAL camera, as that does not work.

The interface produces an error, the camera box remains black and you can click the OK button a million times but it will never proceed.

Under V4L2 you get the following options:

I have tried adding every single one of them but none of them work.

When I select unicam I get video0, also doesn't work.

I have tried switching the camera back by enabling "legacy camera support" in raspi-config and the V4L2 output then becomes different, but the issue remains that none of the cameras selected work.

Ah right, makes sense that it doesn't work as MMAL with modern camera stack. I'm wondering why the cameras are spread across so many /dev devices. CLI can only access one at a time, confusing. Sadly I have no DSI (?) camera module to test whether this is expected, or special for your ISP camera.

After you switched to legacy camera stack, could you retry adding it as MMAL? Respectively does it show "supported" then in:

vcgencmd get_camera

?

I have now switched the configuration back to legacy stack. Under the MMAL selection the problem remains the same. The block remains blank and you can click OK but it never proceeds.

Under V4L2 I have more options.

I will try them out and update this post.
UPDATE. I tried all of them and none work.

The result of the command is:
supported=1 detected=1, libcamera interfaces=0

The result of "v4l2-ctl --list-devices" is:

None of them work in motioneye. ;(
By the way this is the camera:
https://www.aliexpress.com/item/1005001586246249.html

Looks like we should add the device path to the camera name, for such cases where multiple devices have the same name, or one camera provides multiple devices for whatever reason.

If vcgencmd get_camera now reports supported=1 detected=1, libcamera interfaces=0, you should see the camera(s) in the MMAL list, isn't it? ... ah

Under the MMAL selection the problem remains the same. The block remains blank and you can click OK but it never proceeds.

This is unexpected. We check for MMAL cameras via if support.startswith('supported=1 detected=1'):, which should be true as of your output 🤔. Can you verify in shell:

[[ $(vcgencmd get_camera) == 'supported=1 detected=1'* ]] && echo 'Yes it does!' || echo 'It does NOT!'

Well

Camera detected with that command

No camera detected in motioneye

Strange, are there any errors reported?

journalctl -u motioneye

Ah right, you are using the Python 2 version, which contains a nowadays buggy check for vcgencmd get_camera output, so not the one I posted above. Sorry I should have seen this earlier. Please try the Python 3 version, following these install instructions: https://github.com/motioneye-project/motioneye/tree/dev#installation

You could then also retry with the modern camera stack, adding the camera as V4L2 one. But the motionEye version of course doesn't affect the many /dev camera device paths, still now sure whether/how the camera is supposed to be accessed then.

I just tried this, installation got stuck on this

Is this Raspberry Pi OS 64-bit (aarch64) or 32-bit (armv7l)?

uname -m

If it's 64-bit, you need to install the additional development headers, which can be skipped only on 32-bit RPi OS:

apt install python3-dev libcurl4-openssl-dev gcc libssl-dev

If it's indeed 32-bit, then assure that you followed the step to add piwheels as pip source, from where the pre-compiled pycurl wheel can be pulled:

printf '%b' '[global]\nextra-index-url=https://www.piwheels.org/simple/\n' | sudo tee /etc/pip.conf > /dev/null

I can only get a video (as MMAL Camera) if a switch on legacy support with raspi-config. Is there no way to use motioneye without legacy ?

Not yet. Based on other reports the existing /dev/videoN devices cannot be added as V4L2 camera. I guess we'd need to add support for libcamera tools.

Just to let you know I have managed to get it working on the previous version of Raspbian (Buster) through Python3.
The camera will only work as MMAL and not as V4L under any circumstance

I'm having similar problems running Motion with the Arducam 12.3 MP HQ camera (IMX477) with automatic IR-cut filter using 32-bit Bullseye on a Pi Zero 2 W. I did not select the legacy stack in raspi-config, but when I run Motion with libcamerify, it DOES find and use the camera. Unfortunately, none of the mmalcam_params in the motion.conf file are being acted upon.

I'm actually attempting to replicate an existing project that is already working. In the working project, I use an earlier revision of the same camera using Buster on a Pi Zero W, and that project properly responds to the mmalcam_params settings (see https://github.com/zizumara/LPRCam). I would use Buster for the new project, but unfortunately Arducam has changed the camera design so that it ONLY runs under Bullseye (at least that's what their product info says). The older revision of that camera is no longer available.

I'm in the same boat with an Arducam IMX327. I need something to do motion detection and streaming. It's looking hard to find anything that supports libcamera.

Actually, you may still be able to get the older version of 12.3 MP camera that runs with Buster. I was able to do that a few months ago and they sold me the older Buster-compatible camera for $20 more. Send your inquiry to sales@arducam.com. Note that if they do have it, the ordering process is a little confusing. They give you a product code that represents a $1 increment to your order, so you have to order 20 of these to increase your order by $20. Just make sure that you are very specific about wanting the camera that is compatible with Buster. I'm not sure if they are still doing this, but it may be worth a shot.

Only catch is I have a box of 8 if these cameras already. I feel like there will be huge demand for motioneyes and similar projects to support libcamera as more people buy them.

Would it work for motioneyes to listen to a stream on 127.0.0.1 established natively using a libcamera command?

I use an easy workaround for the libcamera/motion/module v3 setup:

Maybe using https://github.com/aler9/rtsp-simple-server/ can be useful to retrieve the camera flux and add a rtsp camera in motioneye ?

Hello,

I'm having an issue with the dev branch. Should the Dev python 3 branch support the Pi Camera Module 3?

Thanks!

No, otherwise this issue would be closed as completed.

In my post above, I described an rtmp solution to make the cam module 3 working with motion. maybe you check that again.

In my post above, I described an rtmp solution to make the cam module 3 working with motion. maybe you check that again.

I did attempt it however I think the shell script dosnt terminate properly and it caused a crash before I could pkill it. So I sort of gave up on that method as it cost me an hour resetting the OS and installing all the other software like SNMP, ect.

I appreciate the attempt to help.

Uh, for shits and giggles, I asked Bard for a solution.

MotionEye uses Motion as its backend for motion detection. MotionEye does not support libcamera directly. However, you can use a workaround to get MotionEye to use libcamera.

The workaround is to use the libcameraify library to create a wrapper around the Motion application. The libcameraify library allows you to use libcamera with applications that were not designed to use libcamera.

To use the libcameraify library with MotionEye, you will need to do the following:

1. Install the libcameraify library.
2. Create a wrapper script for the Motion application.
3. Configure MotionEye to use the wrapper script.

The following instructions will show you how to install the libcameraify library and create a wrapper script for the Motion application.

1. Install the libcameraify library.

To install the libcameraify library, you can use the following command:

sudo apt-get install libcamerify

2. Create a wrapper script for the Motion application.

The following is an example of a wrapper script for the Motion application:

#!/bin/bash

# This is a wrapper script for the Motion application.

# The first argument is the path to the Motion application.
MOTION_PATH=$1

# The second argument is the path to the Motion configuration file.
MOTION_CONFIG_FILE=$2

# The third argument is the path to the libcameraify library.
LIBCAMERAIFY_PATH=$3

# Start the Motion application.
$MOTION_PATH $MOTION_CONFIG_FILE

# Start the libcameraify library.
$LIBCAMERAIFY_PATH

3. Configure MotionEye to use the wrapper script.

To configure MotionEye to use the wrapper script, you will need to edit the motioneye.conf file. The following is an example of a motioneye.conf file that has been configured to use the wrapper script:

# This is an example of a motioneye.conf file that has been configured to use the wrapper script.

# The first argument is the path to the wrapper script.
MOTION_WRAPPER_SCRIPT=/path/to/motion_wrapper.sh

# The second argument is the path to the Motion configuration file.
MOTION_CONFIG_FILE=/path/to/motion.conf

# The third argument is the path to the libcameraify library.
LIBCAMERAIFY_PATH=/path/to/libcameraify

Once you have made the changes to the motioneye.conf file, you can start MotionEye with the following command:

motioneye

MotionEye will start using the wrapper script to start the Motion application. The Motion application will use libcamera to capture frames from the camera and check for motion.

@raziel420
Thanks for the info about libcamerify. However, your instructions are wrong in multiple places, no idea where you got them from?

1. You mix the wording: it is called libcamerify, not libcameraify (no extra a).
2. There is not libcamerify APT package, it is called libcamera-tools:

   apt install libcamera-tools

   Only available on Raspberry Pi since Bullseye (via their kernel repository) and on plain Debian since Bookworm.
3. The wrapper script you use cannot work like that:
   • motionEye does not call the defined motion/wrapper command with the used 3rd argument. How should it even know about it and the path of libcamerify?
   • You call plain motion first, a foreground process which blocks further commands in the script. Additionally, the config file would need to be added via -c option.
   • Even if you fork motion into background, you call libcamerify afterwards without any argument, which is not how it works or can work. If this was the case, no wrapper would be required at all but simply an additional service/call of libcamerify.
   • libcamerify really needs to wrap the executable in a single call, like this: libcamerify /usr/bin/motion
   • motionEye calls motion with a dedicated own config file for each camera, so passing a hardcoded motion.conf breaks it, respectively in practice would double the config file argument.
4. The three settings you add to motioneye.conf are not valid/interpreted. It is even wrong syntax. There is only one setting which is all we need: https://github.com/motioneye-project/motioneye/blob/ad21146/motioneye/extra/motioneye.conf.sample#L23-L24
5. There is no motioneye command, it is meyectl and should not be started manually but via systemd service:

   systemctl start motioneye

This is how it should work:

apt install libcamera-tools
echo -e "#!/bin/sh\n$(command -v libcamerify) $(command -v motion) \"\$@\"" > /etc/motioneye/motion_wrapper.sh
chmod +x /etc/motioneye/motion_wrapper.sh
sed -i '/motion_binary/cmotion_binary /etc/motioneye/motion_wrapper.sh' /etc/motioneye/motioneye.conf
systemctl restart motioneye

However, this does not solve the problem with the multiple /dev/video* devices when trying to add an RPi camera module as V4L2 camera. Although, @scul81 @kaikus do the above steps probably allow using /dev/video0 as V4L2 camera (should be the first shown "unicam" in the list) with modern camera stack enabled, or any other of the shown camera devices? It's still that many in the list with recent RPi kernel (Linux 6.1)?

The instructions above are from Bard, the google's chatgpt.

Ah lol, I missed the re-read the first line. Okay this makes sense and is a perfectly example why one should never rely on any answer one of these AI bots give you for questions without explicit input. Great to shorten text, write summaries, stories and all this, but it does not give you correct/true answers based on research or logic, and it is not even meant to do so.

@raziel420 sorry for thinking this was from you, I was already wondering whether it was mixed up with solution for other software or so 😄. But bringing this topic up probably leads to a solution, at least partly: https://motion-project.github.io/motion_config.html

In the Raspbian version based upon Debian release of 'bullseye' (and presumably later releases), Raspbian allows access to the PI camera via an application called libcamera. libcamera provides access to the camera as a v4l2 device but this interface is only available when using a special application. Users must run Motion using the command libcamerify motion and then specify /dev/video0 in the Motion configuration file.

Matches to what I wrote above (luckily). The other part we need to add in motionEye is to have another list of cameras based on libcamera-hello --list-cameras output, of does this only double with v4l2-ctl --list-devices?

I made a PR for implementing libcamerify support in MotionEye here #2765. Please bear with me as this is my first PR in a public open source project and I'm not a Pyhon developer. Anyways, this patch works for me and has been running since the 19. May without issues.

Check this guys.

Is there anything that people with access to hardware but not that much experience with python could do to help this move forward? Motioneye is still the best open source solution and it would be great to get past this hurdle. The various libcamerify tricks posted in various threads are unfortunately hacks that break down very easily.
