I did get rid of the netflix and YT premium and I'm looking best player out there right now 
I guess simillar to Anything better than a Pi4 currently? - Hardware - LibreELEC Forum
I would like:
- sponsor block
- youtube 4k
- plays as much as possible from the "scene stuff"
- no SD card os
- can do CEC
- 4k UI
- follow media refresh rate for movies
So I ended up with deciding between rPi5 and rk3399 players. This rk3399 does have official libreelec build https://aliexpress.com/item/1005005115649141.html and does have emmc. So should be nice options.
It seems rk3399 can do vp9 for 4k youtube. Are there any advantages for choosing rPi over this? Can it play more stuff then rk3399? Maybe there are still issues with refresh rate switching?
Also any advantage for going amlogic sbc (not a box!) and core elec? Maybe they do some more relevance, license "questionable" stuff?
I do also have 8gen NUC in the drawer - is there a chance to get it working with CEC for everything? It does have some options for waking up on cec in bios, but cannot do control out of box, so would putting pulse eight into JUST WORK? Can such an old Intel cpu just play everything?
It does have typical windows PC issues of not always waking up, etc. But maybe it is just windows and not x86 and with libre elec it would work?
