Starting Pipewire Wayland Screen sharing for OBS and Browsers with a Makefile

[NapoleonWils0n]

I was chatting to drr on another thread about getting Pipewire Screen Sharing working for Browsers

My first though was modifying the desktop entry to start Pipewire and XDG Desktop portals,
but that would mean every time you started the application it would create another instance of Pipewire and the Desktop Portals

Then i thought maybe you could use rc.d script to start everything,
but that wont work because services are started as root and so wont see the XDG_RUNTIME_DIR which is required for Pipewire and the Desktop Portals

So instead i came up with the idea of using Makefile to start and stop Pipewire and the Desktop Portals
for screen sharing for OBS Studio and web browsers

Here are my notes on setting up Pipewire Wayland Screen Sharing on wlroots

cerberus/freebsd/pipewire-freebsd.org at master · NapoleonWils0n/cerberus

So i created 2 Makefiles for Wayland,
one for wlroots based compositors like dwl, labwc, mango etc

And another one for KDE Wayland


To start Pipewire and XDG Desktop ports for Screen Sharing you just run:

make

To stop Pipewire and XDG Desktop ports for Screen Sharing you just run:

make clean

Here is the wlroots Makefile
