Pi Camera V3/IMX Chipset Based Cameras Not Working

Get Help Webcams
2

If I remember correctly from reading about the V3 camera it is using a different sensor than the V2.1 which requires a different driver. Software support may require a "Bullseye" based OS but OctoPi version 0.18.0 is based on "Buster". There is a release candidate of OctoPI 1.0.0-rc3 which is based on "Bullseye".

On "Buster" you probably need to install the libcamera software.

Yes it uses the Sony IMX708 sensor.
Even in the official bullseye image, I had up do a full apt update/upgrade to get the drivers.
Even then it didnt work with my Pi 3B+, I had to enable Glamor graphics which is a temporary fix apparantly.
So I have it working in Bullseye using libcamera - it all works as expected. The quality is great and the autofocus feature is very good.

Once I confirmed the camera was working I tried installing libcamera on Octopi Buster but have not been succesful so far.

I then tried the Octopi Bullseye image (1.0.0 RC3 from October I think) and couldnt get libcamera to work either.

I even tried installing Octopi/octoprint on the offical bullseye image but still cant get Octoprint to see the camera even though libcamera works.

Will have to go back to my V2.1 until someone smarter than me writes a guide I think!

Yeah from a quick read of the RPi blog post announcing it, they aren't supported by the legacy camera stack. To view a webcam in OctoPrint you need some other streaming software (OctoPrint doesn't stream itself). MJPG streamer (that is used on OctoPi) has not been updated in a long time and so I don't think there is a chance that it will be supported there. We will have to find some alternative camera streaming software, that is compatible with libcamera.

ayufan/camera-streamer is one such project I know of, that you could give a go to see if it works.

I have the same problem

v3 wide cam works on Release Candidate 1.0.0rc3 with mjpg-streamer-experimental from GitHub - ArduCAM/mjpg-streamer: Fork of http://sourceforge.net/projects/mjpg-streamer/

what I've done!

sudo apt-get update && sudo apt-get upgrade

sudo apt install -y libcamera-dev libjpeg-dev
sudo apt install -y cmake libboost-program-options-dev libdrm-dev libexif-dev

edit
config.txt
Replace start_x=1 with dtoverlay=imx708

edit
octopi.txt
add to end of file
camera="libcamera"
camera_libcamera_options="-r 1280x720"

reboot

test libcamera with
libcamera-hello

Then use this guide:
https://docs.arducam.com/Raspberry-Pi-Camera/Native-camera/OctoPrint/

skip the first part of the guide
start with:"3.2. Test

I can confirm this works on the 1.0.0 RC3 Bullseye image - webcam and snapshot work.
I did notice that the auto focus didnt work with this method where it did with the official Bullseye image.
The camera Settings plugin works to manually control the focus though.

I also tried on the current Buster image and wouldnt work.
Lets hope 1.0.0 is realeased soon with libcamera and streamer baked in.

Thank you Stefan for the help

You might want to pipe up in the 1.0.0rc3 issue ticket.

Hey how did you get the manual focus control to show up?
I installed the plugin suggested in that Arducam post and got everything else working (finally!) but the plugin settings shows lots of things but not focus. New to OctoPrint/OctoPi so any help much appreciated!

Thanks @Stefan for all this

Thanks @Stefan, those instructions got the camera working on the 1.0.0 RC3 Bullseye image!

Is any one else able to record a time lapse though? I'm able to view the cam, but attempting to have octoprint generate a Timelapse always fails after the print is done and it's compiling the time lapse. Throws up an ffmpeg error/dialog.

I have been messing around with ayufan/camera-streamer based on @jneilliii comments on Add support for raspberry pi camera V3.

I was able to get the v3 working without latency I was getting with the earlier process.

I will post my process after I test it with OctoPrint as I tested it on the latest Raspberry Pi 32bit Lite OS.

13

Make sure to test with the 1.0.0rc3 version of OctoPi image as the base OS will need to be bullseye I think for the camera-streamer app.

14

The base of the RaspOS 32bit Lite I used is Bullseye.

I manually installed OctoPrint using a guide from this forum and everything is working for me.

Not tested time lapse and I had to create a custom service file to get it to work.

I will be testing the RC3 soon.

15

I have the same problem, the official TimeLapse doesn't work and the Octolapse Plugin doesn't work with this camera, I also have the problem that the camera connects and disconnects while it is transmitting:

Done bringing up all configured video devices
/root/bin/webcamd: line 116: 8362 Segmentation fault LD_LIBRARY_PATH=. ./m jpg_streamer -o "output_http.so -w $camera_http_webroot $camera_http_options" -i "$input" (wd: /opt/mjpg-streamer)
Scanning again in two minutes

Does anyone know why this could be?
Thanks in advance

I tested RC3 this week using the following process:

sudo systemctl octoprint stop && sudo systemctl disable octoprint
sudo systemctl webcamd stop && sudo systemctl disable webcamd
sudo systemctl ffmpeg_hls stop && sudo systemctl disable ffmpeg_hls
sudo apt-get update && sudo apt-get -y dist-upgrade

Webcam feeds works fine using default Webcam settings in Octoprint.

I've written a script based on Dark360's comments. It will install everything and reconfigure boot and systemd to use camera-streamer.

Hi, I've used the script above and the camera is indeed working in Octoprint now(required a couple restarts to show up, but it works), however the image is always out of focus. I cannot find any information anywhere on how to trigger the autofocus built into the module, does anyone know?

19

Mine seems to be focused correctly, but I wasn't convinced it was autofocusing so much as dumb luck :slightly_smiling_face:

If I figure it out I'll post a followup and update the script. If anyone else figures it out, please feel free to update the script as well.

I've also noticed that the resolution doesn't match what is specified in the service file so there may be an issue passing parameters.

20

I figured out why you had to reboot a couple times. The service is skipped if the driver hasn't loaded before systemd tries to start it.

I've commented out the ConditionPathExists line and added an ExecPreStart instead. That seems to ensure it tries to restart.

#ConditionPathExists=/sys/bus/i2c/drivers/imx708/10-001a/video4linux

[Service]
ExecStartPre=/usr/bin/test -e /sys/bus/i2c/drivers/imx708/10-001a/video4linux

I've updated the script in github with this change.

Thank you for the script I am going to test it this morning.

do we need to reboot here ? I don't think so
I did this as the whilst reading through the list that sudo apt-get update && sudo apt-get -y dist-upgrade produces, one of the daemons said please reboot. I can remember what it was, so I just thought it was nesscary.

What are these extra packages used for?

sudo apt install -y cmake libboost-program-options-dev libdrm-dev libexif-dev
