* so in order to access the `video` or `audio` tag, use `media.originalNode` or `player.node`;
* `player.container` used to be jQuery but now is a HTML element, and many elements inside
* the player rely on it being a HTML now, so its conversion is difficult; however, a
* `player.$container` new variable has been added to be used as jQuery object
