Fails on >24hr audiobooks & Reader Jumps Around #37

Seems like the failure at >24hr books is because final wav file gets too big.

Another (somewhat) related issue is that ebook reader randomly pauses and like jump backwards to random places.

Have you considered using m4b-tool instead of combining wav files & making the metadata yourself?

or maybe something with my files messes with the formatting.

edit: willing to work on this myself, but want to know if anyone has ideas first

DrewThomasson commented 2 weeks ago

hm, Ill look into this

but in the meantime I suppose you could try removing the activation of the create_m4b_from_chapters() function?

Then you should just be left with a bunch of chapter wav files located in the Chapter_wav_files dir?

Unless of course your issue comes before the creation of the final giant audiobook file

the best is standardize the audio file with a max time, for ex 2 hours, and a consistent naming convention i.e: chapter-1.1, chapter-1.2 etc... to split with ffmpeg something like ffmpeg -i long_audio.wav -f segment -segment_time 7200 chapter%03d.m4b

👍🏻 yeah for now I went the route of just commenting out create_m4b_from_chapters() and use m4b-tool to convert those which works great.
