How to disable full screen on youtube Iframe?

Question

I have a div container and Iframe inside. I assigned width=200 and height=200. when I click on full screen, the video becomes blurry with very bad quality. So, I wanted to see if it is possible to disable full screen on youtube iframe.

Answer 1

"I used ?controls=0 at the end of my url and it resolved the issue."

Your answer doesn't solve the problem, you can toggle full screen also double clicking the video. I tried allowfullscreen="0", doesn't work as well.

The same is for ?showinfo=0; also doesn't work.

?showinfo=0 works only if you change link:
