Corrections of the code for the embed popup. Functions are now in the embed_popup.js
With chrome the player used to play the video even when it wasn't supposed to be displayed and kept playing when we hid the player. When we changed between div and iframe the player started even when it was suppose to be hidden. It's now solved.
