Hello,
i have had an working ambientlight with Libreelec 9.8.2 a long time ago.
Since then i changed my TV to a bigger one with 4k, but i didn´t install my ambientlight.
But i want to do it now.
I had an old setup with the Logilink Videograbber and APA102 Stripes. I tested it, but the LED wouldn´t turn on. So I bought some new parts:
Splitter: Feintech VSP01202
Grabber: HDTV Video Caputure Videoaufnahmekarte Capture Streaming Rekorder Live Streaming hdmi USB
Raspberry Pi3b
SK9822 LED Stripes
Power Supply: https://www.amazon.de/dp/B00MWQF08C?tag=hyperioforum-21
I installed Hyperbian to the Raspberry as told in the guide and in the following video:

I change the user to root.
Unfortunately my LED stripe stays black, even after the first start of hyperion.
My Pin Connection is:
GND: Pin 6
CI: Pin 23
DI :Pin 19
So it´s like for an APA102 stripe
Of course i connected the stripe with the power supply.
Under the Webinterface i did load the profile for my stripes and after that for the APA102 again. But with both profiles the LED stays black.
The grabber is working. Under Live-View the Screen Caputure of my Xbox is showing.
I dont know, why the LED won´t turn on. Maybe the GPIO are wrong, or aren´t used. Because like I said they won´t turn on even after the first start.
A second problem is, that after starting the PI i have to login manually by myself. But at first i want the LED to work.
Could anybody help me?
I´m right before giving up and buying an external solution. But anyhow it should work. But how?
My logfile is attached.
