Hello, I'm trying to add my .cbr comic books to jellyfin but it won't load any content. Files works on local/online reader, but not in jellyfin. I created book-type library and added comics to them with name syntax form docs, I also have bookshelf plugin installed, but it doesn't create any metadata. I also see never ending sppining loading screen when I try to read anything. Please help!

Steps to Reproduce:

Have book type library with .cbr files
Try to read anything from it
See never-ending loading loop

Jellyfin Version

To fix your metadata:
Could not load ComicInfo metadata for "/biblioteka/komiksy/Batman Zero Year (2014)/Red Hood and the Outlaws #25 (2014).cbr" from XML file

This means that the bookshelf plug-in couldn't load the metadata which might be placed inside the comic. This makes sense as the bookshelf plug-in can't open cbr files and check them for metadata. Only cbz files.

Could not load external xml from "/biblioteka/komiksy/Batman Zero Year (2014)/ComicInfo.xml".
This means that the fallback did not work either as the bookshelf plugin could not find a file named ComicInfo.xml at the given path: /biblioteka/komiksy/Batman Zero Year (2014)/ComicInfo.xml
Placing a ComicInfo.xml file (which contains the metadata) at the given location should fix your metadata problem.

The bookshelf plug-in itself doesn't (yet) grab any metadata from the internet except from Google Books (in my experience, Google Books won't find many of my books and comics/mangas). It mainly relies on local files providing the necessary information.

Regarding your issue with cbr files not loading: I can't help much as I don't have any of those. All I can say is, for cbz files, it might take a few minutes for the comic to load.

I see about metadata, i'll add it manualy, but CBR won't start working! I tried with converted to Epub and all works fine but now i need to convert all my comics :(( Ok, i'll try but hope to see some better support in future. Cause wiki clearly claims that jellyfin reads CBR but it does not. Thanks anyway, i'll keep this isseu open as CBR support is still bugged

Yes. To be more precise, it did read everything that was inside the comic as the reader couldn't differentiate between a page and everything else. That's fixed in Jellyfin-Web 10.8.0 (since Beta 1).

but CBR won't start working!

Hm... not sure why. I don't have access right now to my 10.7 instance, but in my 10.8 development instance, cbr files did load on my PC. Thought I only tested it with a file I created out of two random images instead of a real comic.
Maybe someone else can help more with the cbr issue.

Maybe it's then a 10.7.7 bug, can't wait to test 10.8 but don't want to play with beta for now. Thanks ;)
