title: How do I actually add DRM to a video file for EME to interpret?
body: <p>So, I’ve tried googling this a bit but DRM and EME search results haven’t pulled up much in the way of actually telling me what to use on the server-side to implement DRM before a video is sent to the browser for the HTML5 player to decode. Is there some sort of ubuntu/Apache plug-in that adds drm to a video file on the fly then streams the DRM’d file to the HTML 5 video tag? </p>
