OpenCV video stream deployed and processed on Heroku.

This is a toy project for learning how to use a couple of python libraries.

What it does

1. The web client sends video stream data (from the user's webcam) to a flask server using socketio
2. The server does some processing on the video stream
3. The client receives the processed video stream and re-displays the results in a different frame

In the demo site, the server is simply flipping the image horizontally. You could imagine it doing something more useful (e.g. applying some filters, OpenCv processing, detections from OpenCV).
