Unable to use camera with icamerasrc plugin on Samsung Galaxy Book5 Pro (ipu7 with ov02e10 sensor)

I have gone through the steps to install ipu7 :
- driver already included in Kernel 6.17 from Ubuntu 25.10
- installed bins
- installed hal
- installed icamerasrc.

Solved all installation issues (dependencies + gstreamer plugin directory which is not what the rpm packages assumes (/usr/lib/gstreamer-1.0) but /usr/lib/x86_64-linux-gnu/gstreamer-1.0. I only had to move the plugin lib*.so* files.

I run into an issue doing the test with :
sudo gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1920,height=1080 ! videoconvert ! ximagesink

"camerasrc0 n’accepte pas les capacités video/x-raw, format=(string)NV12, width=(int)1280, height=(int)720"
which means : "camerasrc0 does not accept capability video/x-raw, format=(string)NV12, width=(int)1280, height=(int)720"

I assumed that it is an issue with NV12 format, which I can't see when listing formats with v4l2ctl -d /dev/video0 --list-formats,
and changed it to BG12, or GB12 ... (values aout of the v4l2-ctl command and run into the exact same problem.

I have been ensuring to load the ov02e10 sensor driver (modprobe ove02e10), and can't understand what to do.

The other thing I need to understand is once the camera has been tested properly, how can I use it in a webconf app in CHrome. I am assuming that icamerasrc plugin need to appear somewhere in the configuration, but do not understand where it should be configured.

And one strange thing : I have /dev/video0, /dev/video1 all the way to /dev/video31 and /dev/media0. I do not understand why I have 32 devices.
