Bug with CSS3 animation and html5 videos

[onigetoc]

Hi, I discover your plugin after i found the javascript version.
There's bug with z-index in fullscreen mode because of keyframe animation. I fix it with another fade in fade out animation.

I also added a html5 player version playing for exemple .mp4 link.
