javascript - 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

I would suggest hitting the oembed url:

https://www.youtube.com/oembed?url=https://www.youtube.com/watch?v={videoID}&format=json

This gives you the exact video dimensions for videos that are public. I'm not sure about private videos though. It will also return thumbnail dimensions, which seem to be different im some cases, so just be sure to not mix them up.
