title: Get video frames from webcam in HTML and use it for OPENCV python
body: <p>I know it may sound very simple for most of you but i need to get video (Frame by frame) from HTML or java script and use it in python OPENCV.
  I am already experienced with python OPENCV, Deeplearning etc but i have no idea about HTML or JS and how to use Frame from any device(Mobile,Laptop) camera.
  I need to make python app. So need to know some way to get frame from HTML and use it in python code.
  Thank you in advance for all the help.</p>
