How to stretch video embed via YouTubeAPI?

Question

YouTube

So it goes.
There are several vids.
A common class has been written, where all videos are processed and launched, so as not to duplicate the code from YTAPI.
But one video should be in the background. And I can’t stretch it to its full width and height, so that there are no black margins on the sides / top / bottom.
How to achieve this?
