v4l2loopback VS asus-wmi-screenpad

I am relatively new to linux, so pardon if this is a newbie question. I want to install the v4l2loopback module to 6.3.0-asahi-8-1-edge-ARCH. When I manually compile from https://github.com/umlaeute/v4l2loopback, and attempt to install, I obtain a vermagic and kernel version mismatch. Running modinfo:

If you want to stream your webcam as an H264 encoded rtsp stream, it can be done with either rtsp-simple-server or V4l2rtspserver And it is possible to stream a linux desktop (and any program that might be open, like your web browser with the gcode viewer running on it) with the V4l2Loopback device and either of the two prgrams above. It is quite an involved process, but it is do-able.

Effectively these let an app (eg some VToonify tool) generate content that from the perspective of your live streaming app look like they are from a webcam

note: want to get extra fancy and use random sources or have multiple streams use a single webcam source?? check into v4l2loopback -- https://github.com/umlaeute/v4l2loopback

I'm trying to install Linux-Fake-Background-Webcam, which in turn requires 4l2loopback. Following the 4l2loopback manual, I try the following command to install it:

Download the last version bash wget https://github.com/umlaeute/v4l2loopback/archive/refs/tags/v0.12.5.tar.gz

scrcpy and v4l2loopback works well

I've been running Nobara Project on it for the last few months, and have been very pleased with Wayland, even with an Nvidia dGPU. You will need to (build this to adjust brightness on the smaller screen)[https://github.com/Plippo/asus-wmi-screenpad], but I haven't had any unsolvable issues (for me, at least) since doing that.

I just installed Fedora 37 (dual boot with windows), and, since I have an Asus Zenbook Pro Duo, I needed a solution to handle better the second screen. I found this blog post which seems to be perfect for my problem. It led to this github repo which needed dkms and the kernel headers as prerequisites.

But unfortunately brightness control doesn't work for the 2nd screen out of the box on Linux. But someone already did the hard work to write a kernel module for it, then I only had to write an AUR package and a GNOME extension to sync it with the main screen

It was pretty easy on my UX481FLY. Just had to install this module (also made an AUR package for it) and write a small GNOME extension to sync brightness between screens and make some keys work (although it's not done yet. Currently it syncs brightness and makes the toggle on/off and screenshot keys work)

Really well on most distros, but for some reason it hangs occasionally on my arch install (but that's probably just an issue with how I installed/configured it, since it works perfectly in other distros. Or it might be because my home directory is stored on an SD card and not the SSD). Since there are multiple models, I have the UX481FLY, with an i7-10510U, 16GB RAM, Intel as primary GPU, and GeForce MX250 as secondary GPU. And not a GNOME issue, but bottom screen brightness control isn't supported by default, you need to install the asus-wmi-screenpad kernel module. And even with this module, it sadly isn't integrated into the DE, so you need to control it from the terminal. I might try learning how to make GNOME extensions in the future, so I can integrate it properly.
