ffmpeg error

[citadella]

When running a conversion, I see the following error on every run, it seems. I make progress each time, and it picks up where it left off, but I only seem to make 3-6 chapters of progress each time I run it:

pydub.exceptions.CouldntDecodeError: Decoding failed. ffmpeg returned error code: 183

Output from ffmpeg/avlib:

could u share the text if possible, and whether you used special inputs?

[citadella]

No special inputs and there's nothing obvious about the text. From Part 5-30 it only managed 3-4 chapters at a time, then it got better and gave me 5-7 chapters to 45, then did the last 40 chapters with no issues. Weird...
