JS vs pure data (a video file) is an important distinction. I will grant you that. My point is that it's perfectly reasonable to assume users can access this blog post just fine (and my analytics show that is the case for the vast majority of them), because the functionality is built-in to every browser on the planet. You literally have to take action to circumvent the way your browser is intended to work, in order for my site to not work.
