v4l2loopback VS akvcam

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

Hopefully it can run under QEMU with a virtual camera like https://github.com/webcamoid/akvcam ?

https://github.com/webcamoid/akvcam I found it on github. I did not found anything to emulate a microphone. I will try to fork it and customize it to emulate microphone. Because our online exams are conduting in a spying environment through Lockdown browser.
