pibooth-gallery-qr 1.0.0

Use case

Allow guests at an event to scan the QR with their phone (on the same Wi-Fi as the photobooth) and browse the photos from the current session without needing internet, Nextcloud, or any third-party service.

How it works

Two pieces:

1. The plugin pibooth_gallery_qr: on pibooth_startup it writes a session marker file. On state_wait_enter it blits a QR code onto the wait screen pointing to http://<host>:<port>/.

2. The gallery service (gallery.py shipped in the source repo): a tiny stdlib HTTP server that reads the session marker, serves the *_pibooth.jpg files of the configured directory whose mtime is greater than or equal to the marker’s mtime, and renders them with a click-to-fullscreen lightbox.

Install the plugin via pip and run the service via systemd. See the source repo for an example unit file.

Configuration

The plugin adds a [GALLERY_QR] section:

[GALLERY_QR]
  activate = True            # enable the plugin (writes session marker)
  show_qr = True             # display the QR on the wait screen
  host =                     # empty = autodetect (default route IP)
  port = 8081
  session_file = /tmp/pibooth-session-start
  qr_position = bottom-left  # top-left, top-right, bottom-left, bottom-right, center
  qr_size = 5                # 3-10
  qr_margin = 10             # px from screen edge
