Thanks for the error report. Amazon has introduced a change to KFX. I will release an update to this plugin to handle it shortly. (In the next day or two.)

[jhowell]

Version 1.16.0 - 19 Apr 2019

Handle images containing links. (Fixes "story ... content type $271 has extra data: {$179: ...}")

Fix link colors sometimes being applied to the wrong element.

Thank you jhowell. Works well!

Thanks jhowell. Is there a patch number so I can control when it will became available in Calibre? Is it a complicated code?

Thanks again

It is in the 3.41 release. You will need to delete the files containing cached metadata on your device to have it take effect for books that are already present there.

Thanks jhowell, it works for all books except for a very few kfx files

One of these is an italian ebook titled La forma dell'acqua. Camilleri tra letteratura e fiction (Italian Edition). I have seen that on DeviceView the author of this ebook is Silvestra Sorbera & Unknown but after adding it into Calibre the author becames only Silvestra Sorbera.

Attached to this post the metadata.kfx file. Thanks again for the support and patience...

The new code in calibre takes the title from the new metadata, but still combines author information from both old and new metadata. For that book the old style metadata has the author as "Unknown". At this point I am not inclined to make any further changes. It should work for most books.

ok, but... after adding the ebook in Calibre Library the author is only Silvestra Sorbera and not Silvestra Sorbera & Unknown. The "& Unknown" automatically disappears...

Also Kindle device for this ebook shows only Silvestra Sorbera...

Why does Calibre combine author information from both old and new metadata if also Kindle device seems to use information from new metadata?

Attached to this post there is the "metadata.kfx" from another ebook that has two authors ("Giorgio Colangelo & Massimo Temporelli"). For this ebook the adding process works perfectly with the same information (title and author) on both Calibre Library and On Device View. Can you have a look?

Thanks

Both calibre and this plugin should probably use only the new metadata if both old and new are available. I will look into changing this when I have time, but it won't be soon.

Hi jhowell,

- KFX Input updated to latest versions;
- KFX Input continues to work well on all previously purchased ebooks.
- Ebook imported into Calibre from kindle Device using "Add books to library"

Below error log:

One of the KFX files that makes up the book is missing from your device. Try removing the book and downloading it again.

If that does not fix it then I will need more information about that book in order to pursue the problem.

Thanks, I removed the book and downloaded it again. Now it works!

P.S.
I can also confirm that KFX Input and Calibre (Device View) use different methods to read author information from a kfx ebook. I have some other ebooks that in Calibre Device View have incorrect values in author information
("& Unknow" or duplicate values) that, after importing them with KFX Input, are correct!
