QR Code Music Player

This project uses a camera to read QR codes and play the corresponding music file.

Requirements

• Docker

Setup

1. Build the Docker image:

   docker build \

--build-arg VIDEO_GID=$(getent group video | cut -d: -f3)
--build-arg AUDIO_GID=$(getent group audio | cut -d: -f3)
-t qr-player .

```bash
export VIDEO_GID=$(getent group video | cut -d: -f3)
export AUDIO_GID=$(getent group audio | cut -d: -f3)
docker compose build

2. Run the Docker container:

   You need to grant the container access to your camera and audio devices. The device path for the camera is usually /dev/video0, and for the audio device is usually /dev/snd.

      docker run -it --rm \
      --device=/dev/video0 \
      --device=/dev/snd \
      -v ~/Music:/home/appuser/Music \
      qr-player

   docker compose up

Usage

1. Create a QR code that contains the filename of a music file (e.g., test.mp3).
2. Place the music file in the music directory.
3. Show the QR code to the camera.

The script will play the music file in a loop. If the same QR code is scanned twice, it will be ignored.

ARM Compatibility

The Docker image is built with ARM compatibility, so it can be deployed on a Raspberry Pi.

need to run this locally in raspberry to work: rpicam-vid -t 0 --width 640 --height 480 --codec mjpeg -o /dev/video17 --inline
