samsung galaxy book 3 camera device unfound

the webcam is not found as if the hardware switch wasn't working.

```
[gui@fedora ~]$ ls /dev/vid*
ls: cannot access '/dev/vid*': No such file or directory
```

I try to press FN + any function key and still no video file.

I found the culpirt: the sensor is Ov02c10
As far as understand driver is not mainlined https://github.com/intel/ipu6-drivers
I can do testing if people request, but I will not try to make the webcam work otherwise.

Guill

Hi,

We are working on packaging the application and kernel drivers for the IPU6 solution.
The packages live in RPMfusion since some of the libraries are Intel proprietary solutions.

Currently, you can get some of the IPU6 packages from RPMfusion and I am testing them to make sure the user will not face the issue of installation.
Once we finish the packaging work, you could try the IPU6 packages.

Thank you :)

Hello,

I saw the post by Hans de Goede https://hansdegoede.livejournal.com/27276.html
So I tried it.

after reboot opening cheese I get a black capture with error message: There was an error playing video from the webcam.
and in the terminal I see:
```
(cheese:9283): Gdk-WARNING **: 12:50:15.076: Native Windows taller than 65535 pixels are not supported
(cheese:9283): cheese-WARNING **: 12:50:15.182: stream error: can't negotiate buffers on port: ../src/gst/gstpipewiresrc.c(685): on_state_changed (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin36/GstPipeWireSrc:pipewiresrc1
```

on https://mozilla.github.io/webrtc-landing/gum_test.html I have a black video with written below:
```
FPS now: 0.0 , entire capture: 0.1
Success!
```

On the blog I see "This relies on Intel's partly closed-source hw-enablement for the IPU6, as such this known to not work on laptop models which are not covered by Intel's hw-enablement work" so this may be the reason, as galaxy book 3 doesn't ship with linux AFAIK.

Any idea is welcomed
Thank you
