Well, on a raspberry pi 4 4gb, no. It's very sluggish.
Maybe on a 5 with 8gb?
The next device I was going to test though is an Odroid C4 (4gb).
I'm currently going to meet with Bliss Rom creators to discuss getting Netflix etc working on Android as well in a sandboxed manner that still gives 1080p (maybe standard Android though with Flauncher instead of Android TV)
It's tricky to have a privacy friendly device that can also run mainstream, well, streaming clients.
I'm making this to make an easy to use box that works with a plain IR sensor remote for my parents (along with a customized Rustdesk client app in case they need help).
If that's not a problem though (like you want to use Radarr/Lidarr) then you can just a Lineage OS version of Android TV, although it seems Konstakang's version has issues with audio over HDMI on Android 12 and above.
Absol? (j)
