Solution 1:

You won't be able to manipulate the content of an external i-frame. It is called the Same Orgin Policy. You are going to need to ask the user to click on the button.

If you want to subscribe the user to your channel without the user clicking on the button, read the documentation about the Youtube API on how to subscribe a user to a channel. That's your best bet.

Hope that helps.
