pi-cast

Broadcast Chrome browser window and video streams to RaspberryPi

Pi-cast 0.1 pre-alpha

The goal of this initial release is to make it simple and easy to seamlessly cast Youtube videos from your Chrome browser tab to a secondary display through a RaspberryPi on the local network. The backend core Python server apps are at 80% and the rest has yet to be implemented.

####Dependencies/Technologies:

Backend (rpi)
- youtube-dl: for downloading/buffering videos to rpi sdcard
- omxplayer: playing videos on rpi
- Python 2.7: on-demand video player daemon (jobserver.py), database reader and video handler (client.py)
  - Pyro4: Interprocess communication between jobserver.py and client.py
  - python-daemon
- sqlite3: playlist database
- Go 1.0.2: HTTP listen server and database writer
  - gorilla/mux
Frontend (chrome)
- Javascript: Chrome extension
  - famous-angular: MVC framework with the strength of Angular and the shine of Famo.us - generates our Views and communicates with our HTTP server via REST protocol
Future Frontend (Android/iOS)
- famous-angular + WebView/CocoonJS/Crosswalk

####Pipe Dreams:

Encode realtime video stream of browser tab using ffmpeg-PNaCL in Chrome and cast it to rpi
