[Plugin: MediaElement.js – HTML5 Video & Audio Player] Please no looping!

I am having the same problem. Seems like the loop=”false” as documented does not work. Is there another solution to stop the looping?

I think I found a solution, well it fixed it for me.
In the file mediaelement-js-wp.php line 179 change

'loop' => 'false',
to
'loop' => false,

Basically what was happening is that $loop was being defined as a string (with the quotes) instead of a bool so it was always true… then on line 237 it changed loop: true because $loop was defined.
