I can’t disable transcoding globally, I have to mess with horrible config menus on every client I want to use. Library scans take more than 30 minutes on my i7-4790k NAS - after that I just stopped and removed the jellyfin server from it. Just being open source is not enough. Once it starts working as a user-first app I’ll gladly switch over.
For me it’s a bit different - just installing things to get build123d to work is an insurmountable obstacle. Because I’m not a programmer it’s rage-inducing. But I guess that’s how this stuff goes 😉
