How to restrict video from playing on different sites?

We are going to be using HTML5 video to be playing some members only content. The problem is, the Rackspace CDN allows videos to be played from anywhere on any website.

So, my thought is: there must be a way to use Javascript to prevent people from being able to scrape the content.

Obfuscation?
IP Address validation?

What's the best way to ensure that our videos are ONLY played on OUR sites?

PS. If need be, we could always host the videos on our own servers if an Apache directive would accomplish the task...

I have an article here that goes in a similar direction - it watermarks any image that is "hotlinked" from a foreign web site.  You might be able to use a similar design strategy.

I figured it out. It was pretty simple really:

On the HTML side:
<!--DOCTYPE htmli-->
<html>
<head>
</head>
<body>
<video controls width="720" height="306">
  <source type="video/mp4" src="http://www.highpoweredhelp.com/videotest/videos/
</video>
</body>
</html>

Open in new window


Then, there is a PHP script that serves videos from videotest/videos/index.php.

Then I wrote a class called "coldlinker" that handles all the permissions, but the code is pretty easy: build logic that discovers if the link is from an allowed domain, and if it is, serve the correct video. If not, serve something else or a broken one.

if(isset($_SERVER['HTTP_REFERER']))
{
        if($cl->refererAllowed($_SERVER['HTTP_REFERER']))
        {
                $cl->logger->log("Referer allowed: " . $_SERVER['HTTP_REFERER']);
                $path = 'http://1fe0653317283bdcaf77-9b1608f07c89c6f698961f2c1f14233d.r49.cf1.rackcdn.com/goodvideo.mp4';
        } else {
                $cl->logger->log("Referer : DISALLOWED " . $_SERVER['HTTP_REFERER']);
                $path = 'http://1fe0653317283bdcaf77-9b1608f07c89c6f698961f2c1f14233d.r49.cf1.rackcdn.com/youareathief.mp4';
        }
} else {
        $cl->logger->log("No referer present.");
        $path = 'http://1fe0653317283bdcaf77-9b1608f07c89c6f698961f2c1f14233d.r49.cf1.rackcdn.com/goodvideo.mp4';
}
header("location: $path");
