Overwatch 2 CV aim/flick assist for Linux on Wayland

My exploration of low-latency screen capture and mouse interception on Wayland Linux, which tries its best to make this difficult.

Details

Uses wl-screenrec to capture and feed raw video into v4l2 which is then read by OpenCV. Mouse clicks are intercepted via evdev and events are written through uinput.

Detection method is fast (>100 FPS) but dumb; edge case aplenty. Goes to shit in noisy scenes. Not much more can be done without more sophisticated models.

Install wlr-randr and wl-screenrec. evtest may be of some use discovering your peripheral device.

$ pip install -r modules

evdev may require your user be added to the input group. Run as user (will prompt for root pass):

$ python aim.py
