Qqqr: QR Code Music Player

qqqr is a Raspberry Pi Zero W project which uses ZBar and OpenCV to read paper QR code cards encoding Google Play Music track IDs and plays the songs over a Bluetooth speaker. I found that all of them took about 10 – 30 seconds to start playing from Google Play Music after the track ID was identified, whether streaming or pre-caching. My workaround solution was to use Spotify Connect for playback instead of local playback from Google Play Music.
