Synology Docker install doesn't find media

[Sargon]

I have been running the SynoCommunity distribution of Jellyfin on my Synology NAS for a few years and have been happy with it, but recently the Android TV client was updated to a version that is no longer compatible with my server version.

In order to resolve that, I am attempting to configure Jellyfin through Docker instead.  I have completed the initial setup steps and mounted my media locations, but my libraries aren't detecting any media.  Here is what the mounted folders look like in Docker.



When I configure a media library, and click to add a folder, here is what I see initially.



I select the library that corresponds to the folder I want to map (in this case /video-movies) and then I see the following.



When I click on the ellipsis, then the folders change to the following.



This leads me to believe that something is not mapping properly to my media folders, because I can't see my media subfolders and it looks like it is redirecting back to the root directory.  Can anyone tell me where I may have went wrong and how I can fix this?

Thanks!

Here is one more piece of information from the log:

[2024-08-20 04:04:42.912 +00:00] [WRN] [8] MediaBrowser.Controller.Entities.BaseItem: Library folder "/video-movies" is inaccessible or empty, skipping
[2024-08-20 04:04:42.912 +00:00] [WRN] [8] MediaBrowser.Controller.Entities.BaseItem: Library folder "/video-other" is inaccessible or empty, skipping

So I think my library folders are somehow not pointing to the correct location, or possibly I have a permissions issue where the folder is not able to be read.

These are the users/groups that have permission to read my shared media folders. 



I thought 'SYSTEM' would take care of the permissions needed by Jellyfin, but perhaps not.  Note that sc-jellyfin and sc-media are leftover from the old SynoCommunity instance and are not relevant to the Docker install.  Are there other permissions I need to setup in order to properly share my media folder(s)?

Try reading over @Efficient_Good_5784 's guide on setting up Jellyfin on Synology NASes.

If his guide doesn't cover what you need, hopefully he will respond when he is available.

I was able to get the libraries working by granting read access on my media folders to all authenticated users. I would prefer to just grant access to the specific jellyfin user, but I'm not sure what user that would be on my Synology. Does anyone know?
