Pardon my ignorance. What is the Average Joe required to do with this? I have installed your repo but couldnt find this under video addons.

This isn't for the "Average Joe". This is a module for other addons to use. It's main feature it that it converts the video URL to the actual playable video URL. One of the hardest parts of coding a video addon is to access the actual playable URL. Not only does it take some complex parsing and various tricks to accomplish, the method also needs to change occasionally to adapt to changes in the site.

The youtube-dl project works with hundreds of sites and is updated constantly for changes in those sites.

So for instance the YouTube addon recently had issues playing videos because of changes in the YouTube site. If this module had existed at that time and the YouTube addon was using it it would not have needed any intervention by the author to account for those changes, because the youtube-dl project was quickly updated.
Another example of it's usage is in my Forum Browser addon. It allows it to play video links from a variety of sites without me having to do anything but pass in the video page URL.
