But you can't "cast" from Newpipe (you'd have cast the phone's screen and play stuff in Newpipe in your phone). Which anyways is what I do when I start getting too many ads (typically I just shutdown the TV and try to time turning it back on so the ad is finishing. it's something of a mini-game).

EDIT: I'm referring to the original chromecast, not the new "Chromecast with Google TV"

If you get some type of streaming box with an open version of Android TV you can just run Newpipe on the box. The most capable one is the Nvidia shield but for just running a YouTube client there are probably cheaper ones you can get off Alibaba or similar.

You can use the regular YouTube app from your phone purely as a remote, and cast from it to SmartTubeNext on your TV.
