Originally created by @iliasch-dev on GitHub (May 20, 2025).

What happened?

I have a script that creates mp3 files and attaches an embedded image to each one. It then copies the mp3 file to the library path of audiobookshelf. Most of the times the file is scanned correctly and the correct thumbnail is displayed on audiobookshelf. Sometimes however the file is added but with a past video thumbnail (the title is correct). I have to manually delete the file from the library and re-scan in order for audiobookshelf to detect the correct thumbnail. I have a jellyfin installation which scans the same directory and it doesn't appear to be having this issue so i'm guessing it's not my script.

What did you expect to happen?

100% success of scanning the files with the correct embedded image

Steps to reproduce the issue

  1. copy an mp3 with embedded image in library path
  2. let audiobookshelf scan the directory based on directory changes
  3. sometimes it associates the imported file with the a past mp3 thumbnail not the correct one.

Audiobookshelf version

v.2.21.0

How are you running audiobookshelf?

Docker

What OS is your Audiobookshelf server hosted from?

Linux

If the issue is being seen in the UI, what browsers are you seeing the problem on?

I'm not sure what you mean by "past mp3 thumbnail"

Is the previous image still present in the file metadata? Are there multiple covers in the mp3 and the old cover is first?

it happened again and I tried to analyze the relevant file with ffmpeg -i , this is the output . I think that there is only one image embedded (cover) which jellyfin scanned correctly. Audiobookshelf associated the file with an old image from a different and older mp3 file which i'm not sure where it found it. Looks like a caching issue but then again i don't know.

Abs must be scanning in the audio file before you change the image. You can look through the logs to see when that happens. Check the libraries that you have set up and make sure that the audio file is not in any library folder before you move it.

I create the mp3 and assign the image to it in directory A (/tmp) then I copy it to directory B (audiobook lib path) in order to avoid this issue.

I have a script that creates mp3 files and attaches an embedded image to each one. It then copies the mp3 file to the library path of audiobookshelf.

How are you embedding the image? You said it was a script, what command are you running?

the embedded thumbnail of a previously scanned mp3 file

When you say "a previously scanned image", do you mean scanned by Audiobookshelf before, or scanned by something else?

Audiobookshelf associated the file with an old image from a different and older mp3 file which i'm not sure where it found it. Looks like a caching issue but then again i don't know.

Is this other mp3 file still in audiobookshelf?

using eyed3 python lib

it's a previously scanned file by audiobookshelf

it used to be along with other older files but I have them removed from the ABS lib directory after 5 days (cronjob that rm the files from the directory), I then go to "ISSUES" menu and remove them completely manually since ABS won't find the associated files.

The general idea is (a,b,c performed by python script)

a. scrap youtube videos to mp3s in /tmp
b. embed an image to them in /tmp
c. copy the final file to the ABS directory
d. ABS scans the file and puts it in library with the correct image (most of the times)
e. rm files older than 5 days (cronjob runs every night at 02:00)
f. manually clean the removed files from "ISSUES" menu (ABS displays files it cannot find with a "!" which you can then remove from lib yourself, would be nice if it did it automatically though )

you may close it , I found the issue, forgot to change the path in the config file of my script to the /tmp directory (server side) so the mp3 remained in the ABS lib path while still being processed. Impressed however how jellyfin managed to work around it, maybe it keeps refreshing the metadata for each file.
