How can I auto advance after the completion of an embedded video!?

Hi, I'm a masters student desperately trying to work out how to auto advance from one page to another for my dissertation project, AFTER an embedded video has ended. I'd like a function like what the timings question gives, but without having to give it a time frame in which the window can be open (because participants need to be able to pause the video as there are readable elements contained within it). It's clear there IS code that exists within the program that works if it can do this, I just can't work out how I can do this when the video ends.
It's an embedded youtube video iframe if that makes any difference, and my dad is a coder and even his code just won't work in qualtrics! I have managed to include other custom code in the dedicated html and javascript areas but it seems impossible to make this do what I want. Youtube pops up with all sorts of ads and video links at the end of a video, even within qualtrics, and this is the reason I need it to skip when it ends, as I cant have participants getting distracted before they move on!
Just hoping that someone here knows an answer to this. Thanks in advance!
