Audiofile (.mp3) showing up as a subfolder and not a file. about audioserve HOT 7 CLOSED

Thanks for detailed description of the problem.

audioserve is using libavformat (from ffmpeg package) to extract audio meta data.
If audio file contains chapters then it is displayed as "pseudo" folder - so you can access it's chapters individually. It's used mostly for .m4b format, which contains chapters information.
How ever I've never seen chapters info in .mp3 file. (audioserve can split huge mp3 file into equal size parts - chapter like - but it has to be enabled by explicit option - or one can supply additional companion file to indicate chapters - I assume you are not using this).

So I think libavformat is returning chapters for this file - something like one real and one dummy?

Can you share the problematic file?

It seems you are right, I couldn't find that anywhere but of my full metadata output using ffmpeg of my file does show it has 2 chapters there for some reason.

This was originally a chapters m4b file which I split using the m4b-tool utility.
Ironically I found the maintainer of that post the exact issue I had whereby you cannot seem to re-import new chapters data from a modified metadata file.

Will look at trying to re-encode somehow.

Thanks for update - anyhow if you can share file I'll look into it.
m4b format should work with some limitation (no cover, no description).
I should add some sanity checking about chapters metadata ( if there is only 1 chapter do not show as folder etc..)

For splitting m4b I'm using my own wrapper around ffmpeg

from audioserve.

I came up with a short bash script to strip out the chapters but retain all other metadata. It now appearing as it should 👍 Do you still want the file for your own observations?

#!/bin/bash

# creates a direectory scrubbed with new chapoter removed files
# '.strip_chapters.sh <dir>

cd "$1"
mkdir "scrubbed"
set -x
for FILE in *; 
do 
   if [ ${FILE: -4} == ".mp3" ]
      then
         ffmpeg -i "${FILE}" -f ffmetadata "meta.txt"
         ffmpeg -i "$FILE" -i "meta.txt" -map_metadata 1 -map_chapters -1 -codec copy "./scrubbed/${FILE}"
         rm -rf "meta.txt"
   fi
done

Thanks - I've checked - with ffprobe - there are really two chapters - first one is "real" - other has zero length (and starts and ends at end of first chapter) . audioserve displays them both and plays OK. So I think problem is in splitting program, which adds second useless chapter. I've added option --ignore-chapters-meta to globally ignore chapters metadata if people would prefer that.
