If you want on-device FRC then you really should look at RK3588-based TV boxes (or better). It can handle 1080p, but nothing more.
Anything slower won't be usable for FRC, even NV Shield is too weak.

BUT you can try with SVPcast streaming - i.e. doing FRC on a desktop PC in the same LAN. For this use case hardware requirements are much lower.

Because there're so little TV boxes that could handle SVPlayer, we don't want to make a Google Play version, cause it will obviously have 1.0 rating
So only an APK version for now.

Tested with Apple TV 4K 1st gen (2017) and 3rd gen (2022).

4K 2017 based on Apple A10, so it's rather slow. Only 1080p video with low interpolation settings.

4K 2022 based on A15, so it _could_ be powerful BUT someone decided it must be _cheap_ so they removed an active cooling. As a result it always overheating and thermal throttling like hell.
Because of that it can't handle 4K videos too (despite of A15-based iPad can do it).

This mod is a must with 4K 2022:

Modded 4K 2022, with output set to 1080p in Settings and "resize to 1080p" in SVPlayer, can play anything.

Finally all the versions released and have the same feature set.
