I’m writing a script that automatically take screenshots of the desktop (in particular the Minecraft game window) and then use OpenCV to do template matching to recognize if I’ve caught a fish or not.
If I use any usual screenshot capabilities of any python library, I simply cannot take pictures fast enough (at least 10 images per second) to have the script work (under Wayland the usual system top out at 2 images per second).
The only way fast enough I’ve found so far is to use Pipewire to create a livestream of the desktop and get frames of it to do the job.
And it is a complex mess. (At least I’ve found a (very basic and badly documented) library to do most of the work instead of having to work it all through Dbus myself.)
It’s just that what once was a single line in my previous X11 script is now a full on script by itself, and I understand almost nothing of it.
