The player does have a large effect on both those things. A player that supports the codec will not need server hw accept and hdr conversion as it will direct stream. A big issues is these codecs can cost money. So if the player doesn’t come with it the player needs to pay for it, something plex may be doing for those that purchased their subscription.
Jellyseer is a jellyfin comparable alternative to ombi.
A glass may have a spec that allows it to be filled to the brim. Doesn’t mean it’s a good idea, especially when you want to run up stairs with it.
Your going to spill water everywhere.
Yes, I understood that. There are specific OS for Kodi like libreElec, that make it easy to have support for lots of codecs etc. I don’t know if any for specific to Jellyfin, but the Jellyfin App has a better UX than Kodi.
Kodi is a great Linux client. But that’s not what OP wants, the jellyfin app is a nicer UX experience.
There is lots of web based guis. These are accessed on a separate device on the same network (or internet). These use very little resources, all the rendering is done on the client web browser.
Swiftfin is the official Apple TV jellyfin app. Swiftfin is great on iOS, but hasn’t been updated on Apple TV for a while. It also lacks a lot of polish and features but it is being worked on. There should be an update soon.
I’ve been using infuse on Apple TV. Infuse isn’t open source and needs a subscription to watch most 4k hdr content. I think it’s worth it if Swiftfin gets an update soon.
Apple TV is definitely a better experience compared to Samsung and Android. Apps are nicer and there isn’t any ads, privacy controls and privacy statements are much better. Recommended content can also be disabled and only shows when your hovering over the relevant app.
