Thanks, I didn’t know about that.

I love Seafile, but I’m not sure it really meets OP’s requirements. For example I’m not aware of any way to do upload without a login in Seafile.

Honestly, none that are all that great. I tried Kodi in various forms, LibreElec, OSMC, MythTV, Steam Big Picture, and KDE TV (or whatever its called), but you’re just never going to get a great experience with stuff like Netflix and YouTube on Linux.

In the end, I bought myself an Nvidia Shield, switched out the launcher for one without ads, installed Smart Tube Next for ad-free YouTube, and I couldn’t be happier with the results. I’ve got my apps for Nebula and Dropout. I’ve got Kodi and Jellyfin for my home library. It has barely any power consumption, it boots fast, it runs a huge variety of emulators, the included remote works great (plus there’s a remote app for your phone that controls the entire system), and the wife acceptance factor is exceptional.

I’m really big on self-hosting and building all my own stuff; I use lots of repurposed hardware salvaged from companies I and my friends work at and I try to avoid off the shelf products. But I’m genuinely kicking myself for not buying a Shield sooner. It really is the best TV solution for a self hoster.
