I posted a similar question a while ago but haven't received any answers so i thought i might ask a more generic question:
Does anyone know how to, through any means, output true video, not a rapidly changing sequence of images, in a Tkinter window with python?
You probably need an extension like TkVideo or Quicktime to do that, not sure there is a python style wrapper for it available yet. https://github.com/patthoyts/tkvideo
