Demo of using OpenCV to show your webcam in a GUI window.

This demo will run on tkinter, Qt, and Web(Remi). The web version flickers at the moment though
|
|
To exit, right click and choose exit. If on Qt, you'll have to kill the program as there are no right click menus
|

in PySimpleGUIQt (yet).
