I've been using OBS to stream a bit in discord among friends.
I wanted to add the desktop of the lab PC as a video source, while using my laptop to actually stream to discord.


For that you need nginx as well as the rtmp plugin on the receiving machine:

apt install nginx libnginx-mod-rtmp

Edit /etc/nginx/nginx.conf and add the following section:

rtmp {
        server {
                listen 1935;
                chunk_size 4096;
                allow publish all;               

                application live {
                        live on;
                        record off;
                }
        }
}

Restart nginx and check if it's running and listening to the assigned port:

systemctl restart nginx
ss -antpl | grep 1935

You can then stream your desktop with just ffmpeg

ffmpeg -f x11grab -s 1920x1080 -i :0.0 \
       -f flv rtmp://<Receiving_IP>/live/desktop

For OBS set up the stream as follows:

Settings -> Stream -> Custom
Server:       rtmp://<Receiving_IP>/live
Stream Key:   lab

Then set up your scene with XSHM or pipewire screenrecording and start the stream.

On the receiving end use VLC video source -> add -> path/url -> rtmp://localhost/live/lab

Does anyone know of a camera streaming solution for Android that is not DroidCam?

Been using my phone as web cam through USB. But bumping the cable ever so slightly causes a disconnect and the stack to hang until I either reboot the phone or plug it into a charger and out again. That only works half the time though.
