I don't use LibreELEC but just I use it with the usbgrabber. The hardware is just faster, for example the "Size decimation" is limited on older hardware:
PI 1= 7 & the fastest update frequency ( at smoothing section) is 30Hz
PI 3= 4
PI 4= 2
So I guess Hyperion can use better source info with faster hardware for more accurate colors.
Do you have an other PI where you can test the USB gabber? I can switch the grabber between my pi's and they work.
Al tough we have the same chip, mine was advertised as a UTV007 and uses a easycap style case. So maybe there is still some differences?
I'm also running 2.0.0-alpha.6maybe that's the difference?
Can I use a separate power supply to only power the hmdi splitter?
(I want to always power the hdmi slitter, so I still can watch tv without powering the ambilight)
And if so do I need to connect the ground to all the different power supplies?
Yes we have the same output.
I got the same grabber for my second setup. It only works with the NG project. I have to set everything to automatic in the capturing Hardware tab otherwise it doesn't work.
USB capture and platform capture also needed to be activated to get it work...
You could use the image from hyperbian for an easy install.

My only compain is that the grabber captures a very green tint. But it can be compensated with the gamma settings and turning on the the blacklight setting very low.
