--combine works for mp3, but if --output-format m4b is used in addition, only the first chapter is saved

sorrrrrrry.....

No script errors occur, but the resulting m4b file is only (I think) the first chapter of the book. The conversion from mp3 to m4b works fine for the individual chapters, but the --combine flag seems to confuse something. to clarify - this all works perfectly now without the --output-format flag.

It's because the library I use for adding chapters does not support m4b files. It should work with mp3 files, also if you use --combine.

hi - thanks. makes sense.

[jo1gi]

I have made a temporary fix. It just requires ffmpeg. Please tell me if you have any problems.

[catfordfire]

Hi - it didn't work for me, unfortunately. It converted all to m4b and then combined to a file of only the first chapter.

[jo1gi]

I tried again. Hope it works now.

[catfordfire]

sadly not :( this is what I see. Could it be something on my end?

Could it be something on my end?

I think it is. It looks like there is a file it can't find. Maybe try uninstalling and installing it again? You could also try running it directly with python -m audiobookdl [options] <url>.

[catfordfire]

thanks. I'll look into it. I tried the direct command, but different error. I think I'll stick to auto-m4b for now, as that's working well on a docker. Thanks so much for trying to resolve this for me! Hope it helps other people :)
