Thanks for responding. I have read this post, and I don't like it.
First of all, you do have a Video component, and given the many device resolutions out there, a non responsive video component is almost useless. So I think the video component should be responsive out of the box (as any other component).
In addition, the solution in the answer is suggesting to set the height of the video to 50% or something, which makes no sense to me, as it should not take 50% of its parent container, but rather be "auto" based on the actual width and the aspect ratio of the movie (like it works in desktop browsers). But I may give it a deeper look.
