Hi,
I am trying to embed audio and video in an enhanced Kindle edition eBook to be sold on Amazon. It must be possible somehow, because there are enhanced editions on sale (like this FREE one
http://www.amazon.com/Vampires-Bansh...ees+and+angels or this one
http://www.amazon.com/Haven-Kindle-E...9405370&sr=8-1).
I am able to create a valid EPUB either with Legend Maker software (from an RTF) or by making a HTML-file an converting it with Calibre.
I am going to attach the newest set of test files created with Textwrangler (HTML) and Calibre (conversion into EPUB and MOBI).
I understand that the Desktop-Apps do not play multimedia, but Kobo and iBooks on my iPhone open the EPUBs just fine and play the audio/video.
What never works - but is crucial to me - is the MOBI file. In this case, it just displays an empty page, no multimedia elements at all. In other cases there was some kind of thumbnail, accompanied by an error message. Either way, my media did not play.
I also created AZW3 files, but they did not open in the Kindle App on the iPhone. I renamed them MOBI to force them to open, and then they looked just like the original MOBI-files (empty).
Does anyone here know how to end up with a functional enhanced (multimedia) Kindle eBook? Is there a problem with my HTML-files to begin with?
(I understand that there's rumors that only big publishers are allowed to upload these to Amazon - that might or might not be true - right now I am only trying to create the file locally, which should be possible either way, even if it could not be sold through Amazon via self-publishing.)
Thanks so much - if you need any additional information, just let me know!

(Oh, I am working on a Mac, OS X Mountain Lion.)
Best wishes, Ulrich
