Can I do this with Jellyfin?

[dix-hill]

I'm a Plex survivor and current Emby user. I like Emby, it was a breath of fresh air after using Plex for years, but I'm brushing up against its limitations.

Downmixing: How well does Jellyfin handle downmixing 5.1 surround sound to 2.1 stereo? The audio boost setting on Emby doesn't work that well and I constantly have to double/triple the volume on my Klipsch speakers.

Recursive Discovery: I have an elaborate folder structure to organize my TV shows that I refuse to deviate from. All of the file paths for my TV episodes end in Series Name\Season#\Series Name - S00E00 - Title. But, every series is in a Genre folder which means I have to manually add each genre folder to my TV Library in Emby. Then I have to do the same thing for my Anime Library. If I rename a Genre folder or add a new one, then I have to manually add them again. It's demoralizing. I want to add 1 folder to a library then Jellyfin discovers every TV show regardless of how many nested folders I use.

Tree Node Sidebar: I want to see each of my libraries in the sidebar and I want to see a carrot dropdown that reveals the library's genres and their respective media.

Custom Top Bar: When you select a Library in Emby, there's a horizontal menu that has buttons named Shows, Movies, Genres, and Folders. I would like something similar, but I can control the options or maybe replace it with a genre menu.

Multi-Star Rating: The one thing I miss from Plex is the 5 Star Rating feature. In Emby, you can only Favorite something which is objectively dumb.

Write Tags to Files: I know this one is a long-shot, but it would be great if I could write ratings and basic tags to music files. No expectations here.

Thanks for any help!

Depends.  If the audio is transcoding, there are server side settings for how that happens.  Including choosing a downmix algorithm and whether to, and how much, boost is applied.

Dashboard > Playback > Transcoding > Audio boost when downmixing and Stereo downmix algorithm

Client side downmixing is pretty basic for most clients.  The desktop client, Jellyfin Media Player, uses libMPV as the playback engine and accepts MPV configurations.  Meaning you can set custom MPV configs, including downmixing and boosting audio.

Users in another thread came up with the MPV settings you would add to Jellyfin Media Player.

Settings > Client Settings > scroll down to the bottom.  There will be a big text box to paste MPV options.

For the other clients, I am not aware of a way to boost audio within Jellyfin if the client is locally downmixing.

EDIT: Forgot to mention that Jellyfin MPV Shim, another desktop client, will also accept the same MPV downmix/audioboost config since it is pretty much a wrapper for MPV.

Jellyfin behaves the same as Emby in this regard.   Can't imagine why that would be.

The top bar is already a thing, but not customizable.

Jellyfin is the same as Emby in this regard.  There is an existing feature request.

AFAIK, there is no functionality in Jellyfin that will modify your media files, period.

Thanks for the detailed response! I knew Emby was a fork of Jellyfin, but I was never sure how wide that fork was.

Downmixing: I'll definitely try playing around with the downmixing/mpv settings.

Recursive Discovery: Do you know why media servers like Jellyfin, Emby, and Plex struggle with this? It works great with Movies and Music.

Tree Node Sidebar: I'll check out the feature requests.

Custom Top Bar: It is what it is.

Multi-Star Rating: This is another one that confuses me. All I can assume it's just easier to code (I'm not a coder) or it's a trend to emulate YouTube/Social Media. But, I'm so vehemently against it because all of my favorite long running shows vary wildly in quality.
Star Trek: The Next Generation is a perfect example because episodes range from:
5 Stars - Ageless classic sci-fi
2 Stars - Laughably bad, but everyone's having a great time
1 Stars - What the hell were you thinking? No one liked making this and I will never watch it again

Write Tags to Files: I get that's just outside the scope of these apps.

Regarding Recursive Discovery, I guess the difficulty has to do with trying to determine where your arbitrary organization ends and the actual folders that need to be paid attention to begins. There are special functions like extras, specials, cast interviews, and grouping multiple versions of a movie together, etc. All of them are dependent on a rigid naming and folder structure to ensure the everything is identified correctly and consistently. The file that is actually the movie is identified as such. The file(s) that are not the movie get sent down a different logic path to determine how those are organized.

If you allow loose, arbitrary folder structures how do you determine what folders to ignore? You could allow for special folder name syntax to help the parser make that determination. But that would complicate the code more and the stated goal is to not force users into a specific folder structure or folder naming.

Simpler is better, IMO.
