Need some help starting an ambilight project

I have an Arduino Uno and would really like to do ambient lighting like Lightpack but its pretty expensive

I’ve seen tutorials on how to do it using a raspberry pi but is there any way I can do it using my Arduino and rgb addressable Led’s

i need it to be HDMI compatible (which i realise is what the raspberry is used for)
