Not adding metadata to the output file

[filippoteso]

I tried merging .mp3 files in a .m4b audiobook on Windows, using the system command prompt, but the output file has no metadata, cover image, or description.

OS: Windows 11 Pro 21H2 (x64)
Command: php m4b-tool.phar merge --name="The Two Towers" --series="The Lord of the Rings" --series-part="2" --output-file="C:\Users\Utente\Desktop\Libri e audiolibri\Audiolibri m4b\Fantasy\J. R. R. Tolkien\The Lord of the Rings\2 - The Two Towers\The Two Towers.m4b" "C:\Users\Utente\Desktop\Libri e audiolibri\Audiolibri m4b\Fantasy\J. R. R. Tolkien\The Lord of the Rings\2 - The Two Towers"

I also tried to force the metadata, but to no avail:
Command: php m4b-tool.phar merge --name="The Two Towers" --artist="Rob Inglis" --series="The Lord of the Rings" --series-part="2" --genre="Fantasy" --writer="J. R. R. Tolkien" --year="1990" --cover="cover.jpg" --description="description.txt" --output-file="C:\Users\Utente\Desktop\Libri e audiolibri\Audiolibri m4b\Fantasy\J. R. R. Tolkien\The Lord of the Rings\2 - The Two Towers\The Two Towers.m4b" "C:\Users\Utente\Desktop\Libri e audiolibri\Audiolibri m4b\Fantasy\J. R. R. Tolkien\The Lord of the Rings\2 - The Two Towers"

Which version are you using?
You could try to use --debug to get more info what is going wrong.

Thanks for replying, I'm using m4b-tool v.0.4.2

I tried running:
php m4b-tool.phar merge --debug --name="The Two Towers" --series="The Lord of the Rings" --series-part="2" --output-file="C:\Users\Utente\Desktop\Libri e audiolibri\Audiolibri m4b\Fantasy\J. R. R. Tolkien\The Lord of the Rings\2 - The Two Towers\The Two Towers.m4b" "C:\Users\Utente\Desktop\Libri e audiolibri\Audiolibri m4b\Fantasy\J. R. R. Tolkien\The Lord of the Rings\2 - The Two Towers"

... and I got this: The Two Towers (debug).log

Sorry to reopen the issue but I have created a satisfactory audiobook to which I already added a lot of metadata (mostly sorting) via the iTunes app for Windows. I’d like to rename some chapters without having to go through the whole process once again. I wonder if and how this can be done via m4b-tool and if doing that would delete the iTunes specific metadata

m4b-tool meta "Santa Claus.m4b" --export-chapters

# edit manually "Santa Clause.chapters.txt"

m4b-tool meta "Santa Claus.m4b" --import-chapters

rm "Santa Clause.chapters.txt"
