Does your plugin support playing embedded audio and video inside the pdf? Your demo doesn't give that example and I didnt see anything in the documentation or support.
not embedded, but yes it has own feature: http://3dflipbook.net/embedded-video , https://www.youtube.com/watch?v=ekpAGfmPI5k
That looks good. I expect that I can change the css to position the video higher or lower on a page. Is there something in your iframe code that is preventing the video from allowing the user to open full screen?
Yes, there is no allowfullscreen in iframe tag, but of course you can add it)
