I really like how simple and effective this module is for Drupal 7 - though am having a problem with the html5/iframe embeds for youttube; the module seems to be writing embeds with the wrong markup for fullscreen and this resulting in these embeds not displaying the fullscreen toggle...
My embedded youtube videos' code looks like this when I view the source of a node:
<iframe src="//www.youtube.com/embed/ZOco-gIY-g4?width=680&height=382&theme=dark&autoplay=1&hd=1&rel=0&showinfo=0&modestbranding=1&iv_load_policy=3&autohide=1&start=0&wmode=opaque" allowfullscreen="" frameborder="0" height="382" width="680"></iframe>
As you can see - the embed includes allowfullscreen="" instead of simply allowfullscreen
When I looked into video_embed_field.handlers.inc I couldn't specifically see where the extra ="" is coming from!?!?
