Man. Watching youtube through my jellyfin solved all my issues with youtube. The problems that I had was, at some point in me watching videos on youtube; youtube would go ahead and spin up my fan to a point where it sounds like a jet engine (Very unreasonable). With jellyfin, my fan spins normally.
Another issue I had with youtube. Video quality. I personally use pinchflat to pull videos. I have the videos download at the quality of 1080p. I no longer have to fuck around with the video quality π.
Edit: The BIG plus. NO ADS!
