Wanted: Sweet Video Shortcode

Hugo should have an internal shortcode a theme component for embedding videos using the video element so we can get our sweet video content ripped—I mean, downloaded—with the Video DownloadHelper onto our sites. Anyone have a good implementation to start with? Looking for something responsive with a configurable aspect ratio and optional progressive enhancement for JS-supporting user agents. Here’s a place to start: https://github.com/search?q=video+path%3A%2Flayouts%2Fshortcodes&type=Code

Regarding WebM, sure perhaps it compresses a little better but that carrot might not be enough to enable it to surpass MP4 as the Web’s most-used, unencumbered open source video codec AFAIK.
