> So I have a backend that I can send YouTube URLs to running on my Mac Mini that gets the videos with yt-dlp.

I do this too with a mac mini app that does it on schedules across all the channels I like, dumps them in JellyFin with channel art, culls old videos, and uses the Jellyfin api to reindex that category when done.

I just like the lack of ads and no separate YouTube interface… YouTube is just a category in JellyFin.

yt-dlp has gotten spotty about YouTube blocking it, from time to time, though.
