Textbooks / course wiki with embedded Youtube videos?

We have built a knowledge base in Confluence. It is an optional reference material for course participants, not the main part of the course. This material contains a lot of embedded Youtube videos. Also, it has numerous pages that are interlinked. I am trying to find a way to integrate it into OpenEdX, so we wouldn’t have to enroll users in both OpenEdX and Confluence.

Course Wiki won’t do, because it cannot embed video. Neither can I do it with a PDF textbook. I could link from there from Youtube, but i would like videos to play inline, without leaving the OpenEdX environment.

Any ideas or help very welcome. I’ve spent hours looking for a solution.
