To use webcam in chrome/zoom/teams/whatever i use OBS virtual camera, works fine.
Morning. This is the first I've heard of this - can you elaborate?

I see my webcam in OBS, so I created a scene with the webcam video feed and then created a virtual camera that sends that feed back. In chrome I choose this virtual webcam as the source.

Very clever! I'll give that a try. Thank you!

I finally managed to get my camera working on my Lenovo X1 2in1 gen 9 with the ov08x40 sensor.
All I needed was a modified version of the ov08x40 kernel module, the usbio kernel modules and the libcamera package. And v4l2loopback and v4l2-relayd for v4l2 compatibility.
I created a github repo with the required files and packages: https://github.com/henkv1/ov08x40_arch

Thank you! I followed the steps, no errors. The camera is detected (webcamtest.com for example) but the output is black. To have an accurate test, what do you use to test the camera? I want to emulate that so the comparison is the same.

May need some help on getting this to work properly
I have an XPS 9320 (i7, 1260P) with an ov01a10, which is supported.
I managed to get the webcam to work by installing intel-ivsc-firmware. After doing this, I can use it in stuff like cheese, gstreamer (with libcamerasrc), firefox with pipewire, ...
Now, the issues start. first, the camera image appears cut on the sides (cropped) in everything outside of cheese. Also, the OBS source for pipewire is quite broken, but that is to be expected I guess as it says "BETA".
The bigger issues, however, are some issues like the image sometimes stuttering (sometimes when I move away from the webcam, in some programs) and the image appearing dithered (made out of pretty big RGB chunks, which flicker) and with a strong greenish tint. None of this happened while I was still using this repo in pre-6.10 kernels. everything worked fine back then.
Also, I'm having some trouble setting up a v4l2 camera with v4l2-relayd. I tried following the steps in https://github.com/henkv1/ov08x40_arch (sort of, as my sensor has a kernel driver), by doing the following, but I'm still only getting a black image from the v4l2loopback "Virtual Camera"
# dkms add usbio-drivers/
# dkms autoinstall
$ cd v4l2-relayd
$ makepkg -si
# systemctl enable v4l2-relayd
# echo -e "gpio-usbio\ni2c-usbio\nv4l2loopback" | sudo tee -a /etc/modules-load.d/ov01a10.conf
$ rebootSome other hopefully useful outputs:

/dev/video0Yeah also, any way to get rid of all those ipu6 devices? they show up in obs and telegram but not other stuff that uses v4l2, like discord
I just noticed, the webcam stops working after hibernation. Likely related to me having to unload i2c_ljca (as the laptop freezes immediately after waking up if I don't) and reload it again after. I found this https://github.com/intel/ivsc-driver/issues/49
Thanks a lot in advance for any tips or fixes

I just wanted to mention I am the same camp as @alba4k above, and would greatly appreciate a solution, if any
My webcam image seemed to be zoomed in ad cropped.
I also see the list of 30-40 ipu6 devices whenever I have to choose a webcam.
I tried multiple things as mentioned in the posts above but nothing fixed this.

just to add... I have a 9320 (touch) camera works out of box. another 9320 (non-touch) camera does not work...
probably this is the cause

just to say on the one that works...
- gst works
- qcam works
- zoom kind of works(shows camera preview but crashes) with LD_PRELOAD=/usr/lib/libcamera/v4l2-compat.so zoom
- could not get https://webcamtests.com/ complains about permissions in chrome, firefox some odd DOM error.
- quality is 1800s sepia like.
