jellyfin-tizen VS Emby

I cannot help you with this, but this is what I found.

The official repo: https://github.com/jellyfin/jellyfin-tizen

Following this github link.

This is the github repository link I'm following: (https://github.com/jellyfin/jellyfin-tizen/blob/a8629f095dc8ef25878796f549defbb306978246/README.md)

If you're actually going to use the extra features of Plex/Jellyfin over a pure media player like Kodi, generally you would install the sever on a headless box, then install the client on your TV or connected media player. Plex is usually a single click app install on most Samsung TVs. Jellyfin might take a bit more work.

there is a Tizen client (https://github.com/jellyfin/jellyfin-tizen) but it isn't on the app store so you need to install it with dev mode which isn't easy for the average Joe

The app version is just whatever git HEAD was when I built it, d23ca24. The server version is 10.8.9-1 on a RPi 2 installed via apt.

It's unfortunate but you can compile and deploy an app for Samsung: https://github.com/jellyfin/jellyfin-tizen

I used to use Plex until I found Emby. I find Emby easier to use and it does the same thing. Just putting this here as a fourth option for OP. :)

Media Server: EMBY

I use https://emby.media along with private trackers and Usenet.

You can find it here! I have both installed, but I generally keep EMBY turned off until I want to play around with it. You can have both running at once and both accessing the same folders. You can check it out for free.

Emby: Offers premium features with some behind a membership.

I went with Emby, personally. Plex, Jellyfin, etc are all good choices too! :)

For clarity: Emby is still mostly open source (the source code is right here: https://github.com/MediaBrowser/Emby). Emby started incorporating closed source plugins that you only get with the paid version of Emby in order to try and get revenue.

I used Plex until I found Emby, which is far easier to set up and works very well with all my media.
