The script above is the script I wrote to realise my YouTube Counter
https://www.youtube.com/watch?v=yFXkXsWhzqI

Download https://github.com/hzeller/rpi-rgb-led-matrix
And add that script in the bindings/python/samples folder.

Run the script with that command:
sudo python3.4 youtube-counter.py --led-rows=16 --led-cols=32 --led-chain=2 -t 000864 -b 70

And now it should work (of course you will have to replace my YouTube channel ID by yours! l.50)

Tell me if it's clear enough!
