Video controls in iBooks for Mac

I'm producing a Fixed Layout ePub, with video and animation.

Some videos fit the width of the page, nothing to report on iPad reading, but on iBooks for Mac I can't play the video because "play" button is "under" the iBooks "turn page" button!

I see video controls "iPad-like" on Mac, in books like "Yellow Submarine": I've tried to see the code but these books are encrypted.. any help?
