This is an art piece I implemented for a friend with the theme "collaborative change over time".
It serves a webpage with a video and a single button below it. Users can click the button to send the video through a compressor (re-encoder) and iteratively degrade its fidelity.
Internally, it uses:
- flask for business logic
- gunicorn as a dynamic http server (non-static content and http endpoints)
- nginx to serve static files
- redis to store user data (in order to prevent multiple compressions from the same user)
- ffmpeg as a re-encoder to "compress" video files
- post requests to an http endpoint when notifying the server the client has initiated a compression
- websockets from the server to the client when the current compression has finished and a refresh is required
