This python program uses tkinter, opencv, and pillow to create a full-screen Screen-Saver(which is a .mp4 video) when in-activity is detected for 10 seconds. If No Mouse and Keyboard Activity is detected by pynput for 10 seconds continuosly, a full-screen tkinter window is created(which even covers the taskbar!) with a opencv video - screensaver.mp4 as its background. As soon as activity is detected, the window will automatically destroy itself. The program runs continuosly in a while loop, and in-order to stop the screensaver from appearing, the user must stop the program. Converting main.py to an .exe file using auto-py-to-exe can make it easier to run the screen-saver program. The .exe file can even be set as a Startup Application so that the user will not even have to manually run the program!
