Html5 Video Button On Top - Opera Browser

I have video on my website and everything is ok in other browsers but when I checked it on Opera I see this button -> Is it possible to remove this?

Solution 1:

It's this: http://www.opera.com/blogs/desktop/2016/04/opera-beta-update-video-pop/

To disable paste this in url bar: opera:flags#media-detachable-view
