rfid-cinema

Documentation as embedded in the installed software:

This is a presentation system showing a video or an image when the associated RFID tag is presented.
This system was originally developed for O Lab Overbeke, Habbekrats Wetteren and faro.be
by Michiel De Wilde <[email protected]>.

Insert a USB stick with a file named 'config.txt'.
In that file, each line needs to associate an RFID tag with a video or image file.

Use the following syntax:
    id=<RFID tag ID>:file=<file name>

You can use ISO 14443A 'MIFARE' tags having a 4-byte unique ID.
If you present an RFID tag now, its ID is shown below this message.
Use 'id=none' to configure what to do when idle.
Use 'id=unknown' to configure what to do with an unknown tag.

Supported formats are avi/flv/mov/mpg/mp4/mkv/m4v (videos) and bmp/gif/jpg/png (images).

You can add extra fields 'min', 'lost' and 'max':
    - min: minimal duration
    - lost: duration after tag removal
    - max: maximal duration
Valid values are:
    - a time in seconds (e.g; '1.5')
    - 'end' to wait until the end of the video (default)
    - 'forever' to loop the video

Example:
    id=F354422ACF:min=end:lost=end:max=forever:file=myvideo.mp4

This message is shown because the 'config.txt' file (or the entire USB stick) is missing.
Normal functionality is resumed immediately after inserting a configured stick.
