Man I am so grateful for this project, I was afraid it would feel polished enough after having been with Plex for the last few years. But hot damn Jellyfin is so much better and keeps on giving!
I can't tell you how many times I've looked up some feature or low-priority bug only to find the answer is "there's a PR for this that will be added in 10.9", commented like a year ago, glad to see the future plan is more frequent but smaller feature releases!
I've been dabbling with jellyfin lately. It doesn't seem to like my mp3 organization, which Plex had no issues with. I generally use artist/album/songs, though there are exceptions that seem to be tripping up jellyfin. For example, I split compilation cds into the appropriate artist's directory (so, artist/song), and it doesn't seem to know how to deal with that. There are also a few weird things floating around, but those might be due to bad id3 tags in the mp3s.
I know there are some issues with mp3 tags in some songs. For example, my wife's *NSync or N-Sync (or whatever the hell they are, I don't actually care) mp3s seem to have the artist name in different formats, so that's not helping matters at all.
Also, in fairness, jellyfin kind of got a bum start on my system - I installed it and started it, but I didn't have enough space on /var for everything, so the system started having problems. To get it running, I stopped jellyfin and just deleted the metadata directory (getting the server running in general was much more important than getting jellyfin working). I've since allocated more space to /var, and I had jellyfin reread all of the libraries, which seems to have been mostly successful. (It looks like I had the same issue with Plex, because I had moved its metadata /var directory to the media drive, but I forgot for jellyfin.)
I do hope the new version includes some features that are just personal preference, like for example I'd prefer the "artist" view to be first in the Music section, not albums. And I'd like to sort albums within the artist by year, not name (I suppose I could go in and give it the year as the sort key, but I don't want to have to do that for every artist). These are personal preferences, of course, not breaking bugs.
Overall it seems like a decent replacement for Plex. I watched an episode of the Simpsons using it last night on our FireTV, and it worked fine.
Please let there be Media Delete capability for Roku clients, soon. It's the only thing missing for the wife and I. It's incredible without this feature, but would be even BETTER than sliced bread with it!
Any place to sign up for a newsletter to be let known? I'd like to trial moving to jellyfin but I might as well wait since it's not like Plex is that terrible that I have to switch now
So I haven't taken the time to wrap my head around Jellyfin and the Arr family.
I currently use Kodi with Seren and Premiumize. Is there a guide for converting to something to replace Premiumize with what I assume is Sonarr and Radarr? I have a few months until my next renewal though I have to say I've not been unhappy with Premiumize, it's just another bill.
