What is a good video platform that I can capture user data from?

I am looking at creating an online university that will offer on demand videos as an option for attendance. However, in order to ensure that the information was covered and the user actually watched the video we need to be able to capture playback data for the user. Essentially if a video is 10 minutes long we need to be able to capture data in order to determine that the user watched 90% of the video before considering the user to have attended the class.

So I'm currently in search of a either a video plugin or platform that can give us the data we need to complete this. I'm open to options here.
