## Description

The website uses account credentials that are given to every student. I cannot provide them because they are private, but they are of the form "r(some number)" and the password is chosen by the user. I use a netscape cookie file to authenticate. 

I have tried to write an extractor, wrote a regex to match on the website title `r"https?://(?:.+?\.)?kuleuven\.be/.*"`  but got stuck in writing the actual extraction function. While reading the source code of the pages I saw Kaltura is used. So I tried to make use of the Kaltura functions, but they do not seem to apply to the format of this page? 

In one of the other issues it is mentioned that you can reference a Kaltura id directly. Where can I find this id?
