Player app for listening internet radio streams on Raspberry Pi Zero W with an external bluetooth speaker
I need a browser-accessible app to play radio streams on my bluetooth speaker.
See the blog post about this app https://msergo.github.io/2022/09/10/internet-radio-pi-zero.html
An instance of cvlc is spawned using python's subprocess.Popen which playes the stream.
- Extremely lightweight, built with bottle.py library
- Can play "classic" streams and streams from m3u8 playlists
- Can be configured as a systemd service in order to start automatically
