Change the time of a video when moving the mouse?

Question

I stumbled across this WoW website and, inspecting some elements, discovered that the "spinning characters" are WebM / MP4 videos. Go to the Characters section, pick a character, and press this button. This will load up a video of them spinning.

These videos can rewind and fast-forward depending on the direction you drag your cursor (Left = reverse, Right = fast-forward).

My question is simple, what function does that? Is it JavaScript?

Thanks in advance.

Answer 1

It's JavaScript, and this is the code they are using:

//this is for video on stage
CharacterSelect.ui.modelVideo = ModelVideo.build($(".model-video"));

//and this is when the page is ready
$(document).ready(function() {
if (ModelVideo.supportsVideo && !$('html').hasClass('ie')) {
  var modelVideo = videoController.create(".model-video");
}
});
