amperfy VS Audiobooks.bundle

You can self-host something like Navidrome/Ampache and use a subsonic app like Amperfy https://github.com/BLeeEZ/amperfy and download your whole library (or cache as you go along playing tracks).

RSS is only dead to those who don't know how to use it or lack imagination, what a weird thing to say really.

Personally I've been using it for a myriad of things ever since 2007, just recently I discovered you can add .atom to GitHub releases e.g. https://github.com/BLeeEZ/amperfy/releases.atom for a nice list of updates.

I like how neatly I can keep track of everything in one place without having to run around the web and deal with all the madness. If the feed is full of crap I can filter it out with www.feedrinse.com

RSS brings order to chaos, it keeps the signal-to-noise ratio under my control in a world bent on exploiting my web usage

Navidrome and Amperfy is what I'm using and both are awesome. Easy to setup and just work: https://github.com/BLeeEZ/amperfy

Also I noticed Audiobook.bundle is no longer being actively worked on and has been moved to a different project, Audnexus. If you want to try it, I would use Audnexus because it has a release in March.

I just set up Plex with the Audnexus agent (https://github.com/seanap/Audiobooks.bundle), using the Prologue app (https://prologue.audio/) to listen on my phone. It was a little bit of a fiddle to set up, but it's worked wonderfully.

I used this one: https://github.com/seanap/Audiobooks.bundle

You certainly have to massage it to make it work but with a plug-in or two (Seanad guide)and apps like prologue you certainly can get a good and complete experience.

Mp3Tag can be used to bulk edit local metadata if that's what's causing issues. This guide that targeted Audnexus's predecessor is also still relevant if you want to automate some of the process.

I currently have my large collection of audiobooks indexed in Plex as a music library using the Audiobooks.bundle scanner/agent - I setup AudiobookShelf on a VM to play around with it and have so far been very pleasantly surprised by the feature set.

I can't help with the Jellyfin side of things, but I have had great success with this methodology via Plex (even in the free version) using the iOS app Prologue

There is no built-in Plex audiobook agent. Do you have (old) Audiobooks.bundle agent installed?

The latest plex update broke metadata agents. For now you can roll back to 1.24.2. Plex will be release a fix in an upcoming beta release https://github.com/seanap/Audiobooks.bundle/issues/36

Sounds more like an issue with the agent. The fork here allows you to disable downloading artwork https://github.com/seanap/Audiobooks.bundle
