Can you describe a bit more how exactly do you want to put video into it? There are 3 different 'view modes' for this library: book list, 3d pages, fullscreen page. I'm currently using this library for large PDF pages, but only in fullscreen mode.
Anyway, in theory, you can throw any content into it, but performance will be really bad if you don't optimize. Definitely putting a video player, or even UIWebview, into every single page is not advisable. However, you can show thumbnail image on each page, and when replace it with a real video player when user tap on it.
