v4l2loopback VS BlackHole

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

Have you tried Blackhole? It’s a loopback device for macOS.

I did something similar using BlackHole , with an old Mac, not as fast, but I'm quite happy with the results.

This tip is certainly good, but I prefer to use blackhole in combination with standard quicktime, then compress the video to mp4 without losing quality using handbrake.

Use the built in screen recorder with the cmd + shift + 5 hotkey and then pair it with the free internal audio capture software blackhole or vb-audio cable.

FYI, in the audio industry AI is artificial intelligence, not audio interface. Especially these days when AI is becoming increasingly present in all facets of production, it's probably best to disambiguate. DAC would be more clear (digital to analog converter), or you can just say 'interface'.   If you're on Mac there are several options. My preference is for Blackhole which is open source and free. If you've never used github before, it can be kind of intimidating, but just scroll down and read the downloading/installation instructions and it will walk you through it. There are tons of other ones though like Jack, soundflower, etc.   If you're on PC, your options are somewhat more limited. Cable has come up on a few past searches, but since my PC is used strictly as a virtual instrument server, I don't have personal experience with it.

Or, if you want something even more lightweight, you can record computer audio with the macOS screen recording tool using BlackHole: https://github.com/ExistentialAudio/BlackHole

I found Blackhole and got it configured by creating aggregate device and it basically picks up the audio from the built-in speakers via the built-in mic. I then use QuickTime to do a screen recording and pick the aggregate device as the input.... it works but I'd much rather be able to capture the audio from the Bluetooth headset because I usually work with the laptop closed using two external monitors.

Great app. Blackhole is free tho.
