Trying krpano video example in an HTML widget

Hi,

I've tried to insert a HTML widget in my iBook with a 360º video, like the one in videointerface example I've downloaded from krpano.
I can use it without any issue in Safari and other explorers, but when I try it in an iBook I get this message: "HTML5 version not available".

Is it possible to run the krpano videointerface example in an iBook HTML widget?
I'd like to buy the krpano but only needed if is possible to run this example in an iBook.

Thanks in advance!

Ok, thanks for your reply Klaus!
