Error on Mac M4

[DaughterOfMars]

I get the following error when clicking on the convert button after selecting the file:

A couple of questions:

Have you got ffmpeg installed?
Did you select any chapters?

[DaughterOfMars]

Yes, ffmpeg is installed:

==> ffmpeg: stable 7.1 (bottled), HEAD
Play, record, convert, and stream audio and video
https://ffmpeg.org/
Installed
/opt/homebrew/Cellar/ffmpeg/7.1_4 (287 files, 52.1MB) *
  Poured from bottle using the formulae.brew.sh API on 2025-02-06 at 13:12:22

I was not selecting any chapters, as I did not notice the check boxes. When I do, I get a segfault instead:

Firstly, I will look to reproduce the first error you saw.

Secondly, could you try another epub and/or provide the epub that is causing the issue? The reason why I'm saying that is that error appears to maybe be coming from the ebooklib package. In any regards, I will improve the error handling around this case - we shouldn't be having segfaults from something like this.

[DaughterOfMars]

I tried with two different epub files and got the same result. Here is one of them: https://archive.org/details/sacred-and-terrible-air_en/page/n3/mode/2up

[plusuncold]

Two things, as of the just pushed v1.0.3:

• If you select no chapters, it auto-selects all chapters
• That epub has the chapters not listed as DOCUMENT, but UNKNOWN. Those should be read in as chapters now, even though they're probably not 'correct'

[DaughterOfMars]

After updating to the most recent commit I now am able to play the audio via the play button previews. Clicking "convert epub" fails with the following error:
