At the moment the solution I have to view 4:2:2 feeds, Octagon SF 8008 streaming to RPi5 with Libreelec, E2 client addons, works perfectly with 4:2:2 HD feeds.
When I did the scan with the Octagon SF8008 it was right at the beginning of the reports, now with the unstable signal always going to zero I can no longer do the scan.
I don't know of any Android TV box that can do this. I have Mi Box S, ChromeCast HD and it doesn't work, only 4:2:0 feeds, but the E2 receivers can do that too, there's no need to stream.
