I added a shortcode generator/inserter to my copy of MediaElements.js. I'm developing an HTML5 theme for my site and created the generator which I implemented via functions.php. Then I thought it might be useful to others whose memory is as bad as mine with all the file locations and player options available. It's a real hack because I'm not a coder, so if you can improve it, great. Share. The full archive with the add-on is available from my site here.
There's a line of code added at the bottom of the MediaElements.js plugin, so if you use this hack and upgrade you'd have to reinsert the line. There's an additional readme in the archive that explains what's what. Nothing fancy really.
