Have you ever watched a video on a 16 grey level eInk screen? Just under 2 frames per second? Of course, we could go for faster screen refreshes using A2 mode and dithering but that involved an fairly massive quality loss. Given that A2 mode refreshes around 125 ms giving a massive 8 frames per second, video is not going to look very smooth. Not to mention that since Kobo ereaders do not have audio outputs, you are not going to hear any audio.
See
Dithering Implementation for Eink Display Panel for more information. You can google for even more information though that paper does a decent job of covering the basics.
As another way of displaying audio/video in epub3 files, you can play the videos in Sigil though it does insist on adding the backwards compatible toc.ncx file to epub3 documents.

Not absolutely certain what you mean by embedding the video in a page. Video files in an epub document are stored external to the html page and are referred to by links. Pretty much exactly the same as referencing an image. I suppose you could Base64 encode the images and place them directly in the html code but I haven't seen Base64 encoded images used in quite a few years. If nothing else, they take much more space than the original image in return for only need one GET to grab the whole page with images.
