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.

A small computer, large capacity ssd and two WiFi interfaces (2x usb dongles, or dongle plus usb).

Small computer could be anything: raspberry pi (or generic and), nuc mini pc or laptop. If you want to use it without a plug you’ll need to add a battery, usb c powered devices could be more convent to power from a battery.

A ssd is better for this use case. Not because it’s faster, but they are more resilient to being knocked about and dropped. They are also much smaller, especially M.2, and aren’t fussy about how they are mounted.

The two WiFi interfaces would allow you to create a WiFi bridge to access the internet through a WiFi network and access your media server. It would need some configuration, you may also need to have the computer act as a router if you want to use multiple devices without reconfiguring.

It may be easier to have your device act as a WiFi hotspot and have the media centre automatically connect to it. This would make it difficult for multiple devices to use it simultaneously, and you could accidentally allow the media centre to do all its updating and downloading over your mobile connection.

This type of thing is going to be expensive and troublesome to configure unless your already experienced with that sort of thing.

I think a better solution, especially if you already have a media server. Is to set your media server for external access.

To get media when you don’t have internet, buy a large capacity flash drive (or external ssd/hdd). When you have access to your media server download all the content you want on to the drive. I think iOS jellyfin can do this without much modification.

Once out of range of your media server. Delete the content you’ve watched on your device (iPad) to free up space. Connect the external drive through the usb port on the iPad, copy over the next lot of content you want to watch. Disconnect and then watch the content.

Jellyfin can download the content, but you may need another app to play it when you don’t have access to the media server.

This approach lets multiple people access a much larger amount of media, effectively simultaneously. It doesn’t require a large amount of often expensive local device storage - you use cheap external storage. It much less expensive if it breaks or gets lost and has very little configuration -if you already have a media server running jellyfin.

Probably not much for people on a self hosting community, but those that want to get away from subscriptions and steal your data as a service cloud providers that might need some reassurance that they’ll have a working system.

Nixos is an os that’s defined by its config stored in .nix files. Everything is defined here all the software and configurations. Two people with the same script will have the exact same os.

Any changes you make that aren’t in the scripts won’t be present when you reboot.

You could maintain a very custom linux distribution (kinda) by just maintaining these config scripts.

So a user wouldn’t need to install all required software and dependencies. They could get a nixos and the self-host config and adjust some settings and have a working system straight after install.

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.

Same account different servers would mimic discord. So you have one app, but the communities or ‘discord server’ can be their own instance. If it’s mimicking discord it will keep all the message boards private to users like discord, but it could still benefit from Lemmy/Mastodon integration. Many communities have a discord and a sub Reddit having the same account on both may be valuable to some people.

I don’t know the state of voice and video calls in the fediverse, it seems to be the main benefit of discord. Otherwise discord is just a terrible closed version of forums/subreddit/communities.
