How to get YouTube video aspect ratio

Question

I\'d like to get the aspect ratio of a YouTube video, to resize the player accordingly. I\'m programming the YT player using JavaScript.

Answer 1

My goal was to get aspect ratio for any video, not only for those for which I'm owner.

Thus the trick is to use https://developers.google.com/youtube/v3/docs/videos/list with player provided in parts and then parsing width and height of returned embed html.
