jellyscrub VS jellyfin-plugin-kodisyncqueue

You can enable optional Jellyscrub support.

You may want to look at the source for the Jellyscrub plugin. It seems to do a lot of the general things you want including a scheduled job, being informed of new media being added, and saving settings. https://github.com/nicknsy/jellyscrub

This might be a good example if someone wants to make an offline transcoding plugin for Jellyfin.

This update brings MPV and the web client versions up to date, which is particularly notable for JMP since the MPV version was pinned to a 2021 release for a while. I also added experimental support for Jellyscrub and Skip Intro.

Besides that, Jellyscrub allows you to scrub images. To see what I mean, there are some demonstrations in the readme of the repo.

The Kodi Sync Queue plugin does data persistence which you may find useful for building up collections of items to send: https://github.com/jellyfin/jellyfin-plugin-kodisyncqueue

Jellyfin has a server-side plugin called Jellyfin Kodi Sync Queue Plugin that aims to solve it.

So basically because you're killing Kodi, it has to look for those updates on startup. If you leave it running (and as long as the websocket connection stays active), it should automatically sync updates as they happen. There's a bit more that could be done here, but at the moment a lot of the reason for huge updates comes from the server and I can't stop that client side. (More on that here and in the linked issue if you're curious).
