So Got myself a Raspberry Pi 4 Model B 4GB RAM. I have also bought a S-100-5 PSU (20A) for lighting a WS2812 addressable light strip.
My overall goal is to create a Responsive AmbiLight for my TV.
The problem lies between the HDMI splitter and the Pi. I've since learnt that the HDMI socket is an output only, and that the USB sockets 2.0 or 3.0 can't handle the data transfer from HDMI unless I use an expensive capture card.
So basically. What else can I do to achieve what I want?
Note: the video does not need to be HD quality.
