Bugs in content types

Hello,

I have a strange problem after updating the H5P plugin to the latest version: 
I can’t see video controls nor the bottom bar on load for some H5P activities, but when I resize the window these elements reappear, and they disappear again on refresh. To illustrate it, I’ve created a short video: https://youtu.be/mT8uEC0KYAU 

Hi

I Uploaded yesterday to your website a 15.5 mega mp4 movie to an interactive video.

After a few hours i recieved an "video format not supported" message.

I tried to do it several times (each time i had the same result)

this is the link to the interactive video (i uploaded it again now and it is working now)

Please help me :)

Thanks
