# all files looped, GPIO triggered playback
#
# http://mp4museum.org/mp4museum-v4.20.img.zip
# take a v4 image and replace its python script with this
# does not work with v5 or newer!
#
# files must be located in /playthis directory
# files must be named 1.mp4, 2.mp4 etc 
# all files and the directory must be in lowercase
#
# supports only one stick
# (or at least insert playthis stick first)
