Snyder thanks for looking into this. I looked into it a little more and
found that OBS will do the job.

On Wayland, x11grab won't work because there is no direct access to
the display like in Xorg. Instead, you'll need to use PipeWire and
wf-recorder or obs-v4l2sink.
Solution Using PipeWire (wf-recorder and v4l2loopback)
1. Install required dependencies (if not already installed):
sudo apt install wf-recorder v4l2loopback-utils v4l2loopback-dkms
2. Load the v4l2loopback module (if not already loaded):
sudo modprobe v4l2loopback devices=1 video_nr=10 card_label="Virtual
Camera" exclusive_caps=1
This creates /dev/video10, which you will use as your virtual camera.
3. Capture the second monitor and send it to /dev/video10:
wf-recorder -o HDMI-A-1 -f - | ffmpeg -i - -f v4l2 -vcodec rawvideo
-pix_fmt yuv420p /dev/video10
Replace HDMI-A-1 with your monitor's correct name. Find your available
outputs with:
swaymsg -t get_outputs
4. Verify the virtual camera in Zoom:
Start Zoom, and in the camera settings, select "Virtual Camera."

Alternative Solution Using obs-v4l2sink (If You Use OBS)
If you're using OBS, you can install the obs-v4l2sink plugin to
achieve the same effect by redirecting an OBS scene to a virtual camera.

I have Kubuntu 24.04 installed. I managed to get Wayland working
so I
can use Waydroid. Sometimes I need to capture what's displayed on
the
system's second monitor and use that as a second webcam so I can send
that video to Zoom.
Using Xorg, this works.
ffmpeg -f x11grab -r 25 -s 1920x1080 -i :0.0+1920,0 -vcodec rawvideo
-pix_fmt yuv420p -threads 0 -f v4l2 /dev/video0
How do I do this using Wayland?
Thank you
