About

Initial goal

Show one window of the PC on another screen without sharing the whole desktop.

How it was orchestrated

Python + PyGObject using the XDG ScreenCast portal; a small pipewire helper captures the window; ffmpeg serves MJPEG to a browser PWA; captures on damage so an idle window costs about 0 percent CPU.

Outcome

Running: persistent stream with autostart; about 40 percent CPU at 768px/10fps while moving.
