Selfhosted

kodi and its derivatives are not something you should be using. it's shit software on so many levels and we should burn it in the deepest volcanos we got.

try one of these:

1. run lineageOS TV (konstakang images) on it and install regular ATV apps for the services mentioned. so, like googletv except there's no spying and ads and shit.

2. create a normal linux box that has a DLNA sink e.g. using macast. there's no remote control, you use your android/iOS device to send it stuff, like movie from Jellyfin or a youtube video, and it plays it back and allows some control (pause, play, rew/ff, etc)

3. dedicated Jellyfin box; same as 2) but boots right into jellyfin client. it can be run in TV mode where it reacts to only up/down/left/right/enter/back, via gamepad or remote controller. if yours isn't recognised, you can emulate it with InputRemapper.

not familiar with how twitch does stuff.

you also have the option of installing a normal raspi distro and then using a wireless keyboard and mouse/touchpad to run it, but I am of the opinion that once the device gets placed by the TV, it loses all keyboard and mouse privileges and should only be operated via the TV's remote.

When I was considering what to run, I found LineageOS TV provided the best experience for being able to get all the other TV apps, and even Jackbox Games. Many TV apps offer some content free with ads, which can be taken care of. Android TV interface only shows Android TV apps in the main app drawer though.

I loved Debian with KDE Big Screen on the pi for the customizability. You can run scripts like fetching tv schedules right on it (or you can just do this on your jellyfin server), and generally you have more customizability. I run PWAs as well via Firefox. I found Steam Link difficult to get working unless on Buster or earlier.

For remote, I tried out all the ones on Amazon, and found USB connection to be most reliable, and there's one that has a keyboard on the reverse, and an option to do voice control from the remote that's a major 🔑

Jellyfin is not a great experience on a RasPi4. I tried that for a while but i quickly gave up on it. It runs fine on my N100 mini PC, though.

I have much more powerful hardware than you but Jellyfin shouldn’t take more than a few seconds to load directories. The hardware is fairly irrelevant, this was still the case when I was on my old nas (which was an ancient pc that was garbage). Jellyfin doesn’t require much. My library is gigantic too, easily over 100,000 items across music, movies, and tv.

What do logs say? How is your network? When I moved into my new place i went ethernet only and had issues with Jellyfin (and other self hosted stuff) and tracked it down to one cable that was super cheap and limited to 100mbit.

Jellyfin isn’t really geared towards viewing media in a folder structure though.

You may be best off going with a freetube access. TBH I find Jellyfin works best with media that can be scraped or that I’m willing to create nfo files for. My music/tv/movies? These are overwhelmingly fine. Every once in a while a niche show or album requires manual scraping or a custom nfo. But I also have some other collections like music videos. Imvdb exists but is far less complete compared to other scraping sources and as a result I don’t even bother using it, the overwhelming majority of my collection needs manual nfos. When I’ve tried to contribute to it my contributions have sat in pending for literal months pending approval, even for obvious videos by major artists.

I don’t know of any scraper for youtube videos and such a thing would be a tremendous undertaking. If you archive a lot it’s a lot of nfos to create. Perhaps you could make a script that generates them automatically by scraping the description and grabbing the thumbnail as fan art?

I can recomend https://github.com/firsttris/plugin.video.sendtokodi for youtube .. you can share the videos from your phone but you have to deactivate the youtube-addon .. the advantage is you can share videos from a lot of other sites to .. there is a list of site that work with this addon on github

as backup you can try youtube for trailers from the slyguy-repo .. this addon works without api

With the forced upgrade to windows 11 a lot of older mini PCs are getting flooded on to ebay. A little i3 or i5 7th gen with be massively faster then a pi. Plus sips power when idle and completes tasks quicker

I use a rPi3 for this stuff exactly. I have about 300 movies in the folder (I know it sounds like a rookie number but I keep only stuff I know it will be watched) and kodi (through jellyfin addon) only takes a few seconds to load. My jellyfin server is not on the nas itself, it's on a separate docker server for hw transcoding on the fly (and the nas has hdd drives).

I used the piped addon for youtube.

I use kore app on my phone to control kodi. Been working like this for about 7 years.

A minute plus sounds like slow networking, but also, just organize your folders betters and you'll fix the problem right there.

I already get the feeling this is a post where OP is going to ignore all same advice to fix the issue, insist they are n the right, and then double down asking for the moon and telling everyone how wrong they are to suggest fixes though, so...
