[Bug]: some cover.jpg not showing in library

[randall-66]

What happened?

I recently replaced all my covers and most of them are showing across the app. However some of them do not and yet all the ones that dont WILL show when i actually click on the book and am viewing it directly and not in library or homepage or series etc.

I have cleared abs cache browser cache removed the books and readded removed the whole library and readed and nothing seems to work.

Also tried turning off option to not prefer square cover and when i see "invalid cover" and click on that cover the pop up shows the cover perfectly.

All the cover.jpg were made in the exact same way and the "problemstic" files are viewable in any app i have tried and also as i said in abs if i am viewing the book like i am about to play it. And when i look at the one locally stored cover image, there it is! Am i missing some obvious caching issue?

What did you expect to happen?

Covers to be viewable across app not just on play screens

Steps to reproduce the issue

1. Deleted all cover.jpg and cover.png files with powershell script from audiobooks shelf nas share
2. Created new cover.jpg file for each book and saved
3. Copied over all new cover.jpeg file from local audiobook folder backup

Are the books that are showing the cover downloaded books?

[randall-66]

No none of them are downloaded. In fact i removed the entire container and reinstalled into a new lxc so now on the brand new 2.18 from 2.17.7. Loaded up the library again and same issue. Here are a few screenshots to help. Especially in in ex 3, 4 and 5 you can see it shows invalid cover and that a local cover.jpg is stored and i an even click on the invalid cover and it pops up the cover image! Haha i feel like im going to kick myself for not seeing whatever it ends up being......

[advplyr]

Can you check the server logs? The covers that show are most likely showing because it is the raw cover image whereas the covers on book cards are thumbnails auto-generated and stored in /metadata/cache/covers/

[randall-66]

the logs seem to have alot of ffmpeg errors about resizing images (below).

What is the format of the cover images that don't load?

[advplyr]

I see in the ffmpeg error log it is jpeg. One thing you can try is to run the ffmpeg query that Abs is attempting to run.

ffmpeg -i "/mnt/audiobooks/Jim Butcher/The Dresden Files/Vol. 17.1 - Little Things {James Marsters}/cover.jpg" -vf scale=400:-1 output.webp

[randall-66]

i tried that and it is failling.

This may be an issue though, the script i created (amateur here!) to pull embeded covers from the .m4b files i dont thin properly accounted for converting the image. This file is labeled as a jpeg but you can see the file command returned that it was PNG image data. Is that possibly my issue?

file "/mnt/audiobooks/Jim Butcher/The Dresden Files/Vol. 17.1 - Little Things {James Marsters}/cover.jpg"

Output:
/mnt/audiobooks/Jim Butcher/The Dresden Files/Vol. 17.1 - Little Things {James Marsters}/cover.jpg: PNG image data, 500 x 500, 8-bit/color RGB, non-interlaced

[advplyr]

Ah yeah that would be a problem. You can change the extension to png and run the ffmpeg command again to be sure.
