[question] what are good alternatives to jellyfin?

I have a vps where I host a few things and I tried adding jellyfin. It worked and while scanning media railed the CPU/ram, once it was done everything was smooth. However, despite having all dependencies a bunch of videos didn't play. I also don't need the music and ebooks side of jellyfin as I'll be using other things for those (funkwhale for music, still looking into the books and comics ) So, which self hosted alternatives do I have for videos and books/comic books? I need things that only do that but don't well. The video one needs to have a client I can install on a android device I have plugged ony tv
