Has anyone heard of any update related to adding audio and video to your Kindle files? I wanted to do the same. Found this sample enhanced ebook (Jay-Z Decoded Enhanced Edition) with audio/video for Kindle apps for iPad.
I've tried using the latest Kindlegen_v2.4 to generate the mobi with audio/video included but got the same error message when loaded to Kindle apps for iPad "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."
I tried extracting the mobi file and found out that the audio and video files are not included when the mobi file is generated. Not sure if this is considered as a bug for the tool or there is another process from Amazon that would take place to include the audio/video on the mobi file.
Any response would really be appreciated. Thanks in advance!
