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.
You need the print screen key for something else is what you’re saying (I had trouble following your reply)?
Can only speak for KDE, but you can easily change the screenshot shortcut to something else in settings.
