stash VS calibre

Also, something that comes pretty close to what I want to do is stash. However, it doesn't handle ebooks, and my library is not nsfw and shouldn't rely on an external database (as no external database for my field of interest exists afaik). But stash ticks almost all the requirements.

Stashapp - https://github.com/stashapp/stash

I'm basically looking for https://github.com/stashapp/stash + https://github.com/alexta69/metube - basically you copy paste a pornhub link; it downloads a local copy and tags it away with everything from the original site.

https://github.com/stashapp/stash - "a self-hosted webapp written in Go which organizes and serves your porn."

Stashapp, its meant for porn but it has a feature that would let you have a literal wall of videos playing at once. it doesn't play the entire length but you can set how many segments and how long per segment so like 20 segments of a video and each segment can be as long as you want like 10 seconds. https://stashapp.cc

I saw someone recommend Stash as a "Plex for porn" if that's what you're looking for. I don't know if it downloads stuff for you, though.

Except for the bug in the latest version in which it doesn’t stay fullscreen when you switch between videos.

Not to be confused with Calibre, the excellent ebook software by Kovid Goyal:

Glad you were able to fix it, but what about trying Calibre? It is free and makes it easy to adjust things, add info, and change front covers.

Or using Calibre (pdf or azw3) https://calibre-ebook.com

There are already some very good ebooks solutions out there so there's really no need. Calibre for the backend and database management, Calibre-Web for the front end, and Openbooks for content.
