Is there a library for overlaying questions on embedded YouTube videos?

Question

In the AI class course by Stanford, they use embedded videos for teaching the course.

After each video users are asked to answer a quiz question.

Is there a library one can use for accomplishing this?

I'd like to use this in creating online content for my students as well.

Answer 1

It looks like they implemented it themselves. So that would probably mean there's no general library, or they would probably have used that.

They did a nice job, by the way.
