pravid / python-webcam-flask

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 sophisticated (e.g. applying some filters), but obviously I was too lazy to implement anything cool.
