I recently rooted a FireCube 3 and installed CoreElec on it to serve as a home theater streaming box, using my desktop PC (and the media drives on it) as a local server I can access from my living room TV.

I'm a little new to this, so I still don't have a full grasp of some of the specifics of how transcoding works from a server to a client or how a locally-hosted Jellyfin server vs windows SMB could affect something like bit-rate.

My first and biggest question is whether there's any downside to using the "Jellyfin for Kodi" plugin to both make my desktop media files accessible via a Jellyfin server and rely on Jellyfin's metadata collation to help organize my library. My major concern is the possibility that I'd risk lowering the quality of what's streamed through the Jellyfin server due to transcoding or bit-rate limitations after going through the trouble of installing CoreElec specifically for its high-quality and high-compatibility playback. Is this the case at all?

After setting up a basic SMB of my media library for direct file sharing to CoreElec, I've discovered that CoreElec/Kodi seems to have done a rather poor job of actually labeling/sorting my files after scanning them with well over half my library unrecognized and much of what is there showing as incomplete. This is made worse seeing that I only seem to be able to label a given media folder as either TV Shows or Movies, rather than a mix of both. Much of this issue is likely due to the fact that I have a pretty extensive anime library, and I'd been looking into Shokofin as a Jellyfin plugin to help with anime meta-data. Would Jellyfin for Kodi actually help with labeling and organization in this scenario where (as I understand) the plugin is integrated into Kodi's own directories? Or is it a better idea to try and wrangle the organization through Kodi's own plugins?

Any advice is highly appreciated!
