Display streaming video and result of a python code at the same time in a web-browser

I need to display a streaming video and also the output of a python code running simultaneously. What is the开发者_JS百科 best framework to go about designing it.

Are you actually sending the video, or are you sending an HTML page with an embedded video (either with Flash or HTML5)? If the former, showing other output would be impossible. If the latter, you can have it anywhere else on the page.
