v4l2loopback VS obs-v4l2sink

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

There a temporal workaround but it's quite old and honestly I don't know if it still works on modern systems. It's basically to use this plugin https://github.com/CatxFish/obs-v4l2sink If you manage to install it it should give you the ability to choose what of your loopback devices should be the virtual cam. Good Luck!

well the easiest way I can think of is just using the OBS virtual camera thing (Unsure if they released it officially on Linux, but there is a plugin for that [1]).

Use chroma key to remove the background and add a video there, possibly on a loop.

In case the built-in filters are not sufficient or unavailable, the workaround would be to install OBS. In OBS, set up your webcam as a source, and set up a view that has all the effects that you want. Then set up a virtual webcam: if you're using Windows, using OBS Virtualcam; if you're on a Mac, using the "Start Virtual Camera" button built into OBS; and if you're on Linux, using the v4l2loopback kernel module and the obs-v4l2sink plugin. You can then configure Zoom to use this virtual webcam, which has all the extra effects that you configured.

It also links a plugin thing for linux https://github.com/CatxFish/obs-v4l2sink and mentions that something might be in development for macOS

PS: Seems the feature is now part of OBS 26.1! I have not seen it in my version. I'll look further. Thank you for your reponse!

Try using OBS studio along with something like v4l2sink.
