Programs for youtube, instead of the browser, to skip ads?

Currently, programs like mpv, haruna, smplayer, yt-dlp, and other downloaders, can all still play or download youtube videos without the ads (for now).

Surely there has to be some program(s) available as an interface for youtube, or that would have the browser launch another player?

I've just started looking myself, so I'm wondering what other people might use for this?

I've found a couple browser addons that should allow me to launch youtube videos in mpv, but I was wondering if there was a full application that would show me videos from my subs, etc, like the browser does, but uses a player like mpv to play them.

Plus there's the videos that are restricted that require you to be logged in to view.
