Internet Explorer 11 support
Alerted by one user we have decided to look closer at not working player on each of demo pages, even if IE 11 is a pretty old browser and Micosoft ended support for this last version of Internet Explorer in June this year. Explorer was once a major player in the internet, today it holds about 2-3% of the market, and IE11 share is 0.32% only.
But this was not the end of the trouble with IE 11, the player still was not playing. Then we found the reason is a minimized version of video.js script. Once we minimized it on behalf, the player suddenly started to work on nearly every demo page
However, remember, that playing videos on IE 11 cannot be same smooth as in modern browsers. Also not every player feature will work. It is not possible to set graphical filters to video, VR display is not supported.
