Interesting, again at least in the android/web/Linux client ecosystem I’ve not experienced any of those issues, and Jellyfin has caused me less family tech support issues than Plex or Emby. I guess it all depends on the platform, and how much outside of just media consumption you’re wanting your server to do.
Thanks for the follow up.
I think the transcode part is decided by the client, but in the Jellyfin server admin you can control if a client can request a transcode (which may not be actually needed - and if you know what client they are running it’s probably easier to decide). This could just be client setting though, because I know on Jellyfin you can change the “backend” in the client that it tries to use and can make the difference on things like x265/HVEC playing back or not.
