Hi Dave!  Is this how you embed these videos?  I'm have a customer who creates custom training video in aviation, and they don't want the videos being downloaded, or YouTube links being passed around.  This seems like the solution.  I see you're html video link points to a blob...so, I'm assuming the technique in this video is what you're actually using.  If so, I'm gonna utilize this in my project.
