I'm using bootstrap 3 in conection with accordion 2 and superszed 2. In the sections of accordion 2 I've placed html 5 video player. It works with Firefox and Chrome, but not so with ie11.
With ie11 the thing on one hand is, that the videos do not fill the hole screen in the fullscreen mode and on the other hand will cut off in the fullscreen mode every time when the pictures changed in supersized 2.

Here’s the website
www.subroom-blues.de

So what should I do?
