Problem converting .kpf file to .epub

Jennifer G · 06-26-2019, 01:11 PM

I am attempting to create an ebook in Kindle Create that has embedded interactive audio, then convert it to epub in Calibre. I have added the KFX plugin, so that the .kpf file will be readable by Calibre. But when I try the conversion to either epub or mobi, I get an error message that begins:

ERROR: KFX conversion failed: Cannot convert Presentation1b Exception(u'Unknown com.amazon.yjconversion feature: yj_audio-2\nexternal_resource has extra data: zsSHNix_EhEDg_nv8mmGC904

Maybe there is some other plugin that will help with the audio? I've searched but haven't found anything obvious. Thanks in advance for any help you can offer.

The next release of the KFX Input plugin will accept the yj_audio-2 feature. In the mean time you can force the conversion to complete by selecting the option "Allow conversion to complete even if errors are detected" in the KFX Input tab of the conversion dialog.

However the results of converting this sort of book may not be very useful. KFX textbook format will convert to a fixed-layout EPUB containing one image per page, each with a hidden text overlay. The audio will be converted as HTML "audio" elements.
