Does swift-toolkit support non-MP3 audio files?

[domkm]

I just tried opening a few non-DRM M4Bs, both as individual files and as ZABs, and got Publication.OpeningError.unsupportedFormat errors. Is this expected? If it is, what needs to be done to enable non-MP3 audio formats?

A publication asset is recognized as audiobook if it contains resources with these extensions:

Could you share the full list of entries in your package?

I'm glad to hear that it's supposed to work.

I'm using M4B files from Librivox. Specifically, https://archive.org/download/2br02b_0801_librivox/2BR02B_librivox.m4b and https://archive.org/download/trialofoscarwilde_1601_librivox/trialofoscarwilde_1601_librivox.m4b. I also zipped a directory containing only the former to test ZAB opening. In all cases this returns an unsupportedFormat error using swift-toolkit 2.6.1 (at least on my machine), while MP3 files and ZAB of MP3 files open without issue. I've tried opening these M4B files in QuickTime, IINA, and Apple Books, which all seem to play them without issue.

Some code was missing which prevented zipped audiobooks without a manifest from being recognized. Could you try again from this branch? #403

That seems to be working for my test cases. Thanks!
