Support Youtube enablejsapi

Problem/Motivation

Hi,

I need to add a "autostop" for embedded youtube videos when user scrolls away from the video.
For that the iframe tag should contain enablejsapi=1.

Where should I look, how to add this in the embeddings? I am using
https://noembed.com

Steps to reproduce
