Artnet to strip led

Hi everybody,
I saw this video on youtube: Resolume Artnet Arduino Mega Pixel Strip WS2812 - YouTube
I tried to search out on the web something but without any success.
Is there anyone that can help me to figure out how to create this project.

I would like to convert the art net protocol to control a dimmerable strip led using a video software.

The video says:-
Code at GitHub - adafruit/Adafruit_NeoPixel: Arduino library for controlling single-wire LED pixels (NeoPixel, WS2812, etc.)
