I've downloaded books with embedded audio from Amazon that will play in the Kindle app on my iPad.
I wanted to explore these capabilities for myself so downloaded a copy of kindlegen and the Kindle Publishing Guidelines which explains the steps that should be followed. However, I have not been able to get the Jabberwocky sample that is included with the kindlegen download to work.
The book opens ok and shows the audio icon, but when I click it I get an error saying "Unable to play audio" - There was a problem downloading the audio content of this title. Please remove the book from your device and re-download it."
The audio is embedded in the sample mobi file, so it should not need to download it. I've even tried rebuilding the sample on both a windows PC and a mac, in case there were issues related to one of these platforms or the sample was not built correctly in the first place. However, I always get the same error.
If I just open the html file that is packaged in the mobi in a browser, the audio plays fine, so I know it's not a problem with the audio file itself or the html reference.
Hi, I'm struggling with this, too. I did a lot of trying today, using http://www.macroplant.com/iphoneexplorer/ to see what's happening in the file system on the ipad. I think original kindle books are re-packed after the upload to amazon and there are additional mechanisms for decompressing the mobi file. I loaded a title with video from the kindle store to see where the files are saved. Media files are stored in a separate folder after downloading, and my guess is that this does not work with selfmade oder sample mobi files.
I would be glad if someone from Amazon could help, we have to test our enhanced books before we uplod them, right?
Unfortunately or fortunately I'm not from Amazon. But I investigated this problem a bit further. I currently have the same problem. Neither my multimedia-mobi nor the Jabberwockey-sample supplied with Kindlegen works on my iPad. Although the Kindle for iPad App states that my ebook contains "audio/video", it is unable to playback video and audio.
So I downloaded from Kindle Editions a Ebook with Multimedia-Content. I transferred the file to my Mac, unzipped it and wondered: There were no multimedia files incorporated. The src attribute of the video tags in the XHTML referred to a not existing media directory.
I started the iPad explorer again and when you follow the path "/Apps/Kindle/Library/eBooks/" you'll find your purchased Mobis (in AZW-format) and a folder named "Media". Therein are all multimedia files stored.
Now, my problem is how to supply the videos, when you can't pack them in your mobi file?
