The closest I got adding audio/video to my ebooks on the kindle worked ONLY if played with on the Kindle App for Android and iOS App, (see 'Scratch' Scratch - Horror eBook ).
I also had to include direct links just in case. I thought I would come back around and see where we were in the ability to add audio and video to Kindle/.mobi eBooks.
I did a search through current threads. Doesn't seem to be a hot topic, but I thought I would put it out there again. I understand the principals behind the HTML5 enhancements and it's use through .mobi, but I'm not seeing it around for the common man to add it to their ebooks. I believe only a higher choice few can (Stephen King books, etc).
Any thoughts? Can anyone point me in the right direction?
I've never troubled myself with these options, in part because I own a K3 Keyboard so am very conscious that Kindles seem to last forever, and that there are millions of devices out there that can't handle the fancy stuff. Why would you shut these people out? They are probably more likely to buy books than are the owners of tablets, who if they want to see videos can download classic movies for free through Amazon Prime.
(My kiddos live on a boat, and in 2005 they bought two Sony Readers to take with them on a world cruise. After eight years in a salt-water environment, those venerable gadgets are still going strong, even though the family has now added three Kindles to the mix.)
You can embed a video if you build your ebook using KindleGen v1.2 or if you build your ebook using the latest KindleGen and then extract the old Mobi7 file (a.k.a. KF6 file) from the resulting .mobi file using software called KindleUnpack. Note that embedded video does not work on the majority of Kindle devices. It only works on iPod Touch, iPhone, iPad, Kindle Fire HD, Fire HD 8.9", and 2nd-generation Kindle Fire. For coding instructions for embedded video, see page 48 of Amazon Kindle Publishing Guidelines.
That's a great idea, but how does it work in practice? Do you bundle KF7 and KF8 versions together somehow, or do you actually create two different books, one for the oldtimers and the other for the tablets etc?
If you use the latest Amazon's tools (Kindle Previewer, KindleGen, or the KDP converter), they will build a .mobi file that contains two formats: KF8 and KF6 (for compatibility with old devices). My latest testing shows that Amazon splits that file later and sends the KF8-only part to the newer devices and all reading apps, and sends the KF6-only part to the older devices (K1, K2, and DX).
KindleUnpack can split the latest version of the .mobi file, and produces two separate files: KF6 (i.e. Mobi7) and KF8 (aka AZW3). You can also make the KF6-only file by building your ebook using KindleGen 1.x. Drag-and-drop the EPUB file onto the file kindlegen.exe
The KF6 file still works perfectly on all devices and in all reading apps and you can publish it on KDP. If you publish the KF6-only file, Amazon will be sending it to all devices and reading apps. I am not sure you can combine the two separate KF6-only and KF8-only parts into one master .mobi file. (It's easier to just build a new combined MOBI using the latest Amazon's tools.) I am publishing all my ebooks as KF6 files (now 10 ebooks under my belt) because I like Mobi7.
