Update video.js to latest 4.x version

Steps to reproduce

Steps to reproduce:
1. Currently video.js is version 4.7. There is already a version 4.9 out and a version 5.0. As 5.0 does not work without some refactoring of the theodul plugin code, but 4.9 does it makes sence to update the player to the last 4.x release.
