@rom I have jellyfin (no transcoding tho), navidrome and a calibre web

Maybe you should try out piped. It's a minimal web frontend for youtube, similar to invidious. It can give you a single rss feed for all channels you follow.

I already use Piped 😛

I actually figured that out! but I decided to get the feeds directly from youtube since the instance could end up being down or something

Then why did you bother importing 1200 feeds? Do you prefer having each channel in it's own feed?

my brain blacked out

I literally realized my mistake after I clicked the import button xD

The purpose would be, that my rss reader has notifications, while piped does not

If you really want notifications, there is libretube for android. Although I don't get why you'd ever need notifications when using piped. You just open it and see everything new that has been uploaded by the people you follow.

I didn't know Libretube had notifications, huh

What I did makes no sense, I just play around like that and experiment with things. What I do doesn't usually have a greater purpose xD
