Flash doesn't work on iPads.
thank you for your answer, are there alternative way for me to format the file so it can play the video ?
Trade up to InDesign CC2015 (that's the latest version of InDesign) and create a fixed layout ePub.
The fixed layout ePub format can do the multi-media stuff but it's only playable on certain devices.
iBooks Author is excellent for iPads but the format can only play on Mac computers and devices.
Each eBook format has advantages and disadvantages.
Lynda.com has excellent tutorials for learning about the various formats, for example: Watch the Online Video Course Creating Fixed-Layout EPUBs with InDesign CC
Thank you very much for your help. I will check out the link.
I will see how much would it cost for me to trade up for indesign CC2015
