Visualiser for UDP 16bit pcm streams using RPi and NeoPixel
Mopidy setup to stream on "jack" audio device and stream udp under [audio]
output = tee name=t ! queue ! alsasink device=usb t. ! queue ! udpsink host=127.0.0.1 port=5555
We need to use USB device because the neopixels break the pi's soundcard /etc/asound.conf:
pcm.jack{
type hw
card Headphones
}
pcm.usb{
type hw
card Device
}
