Youtube-player: add support to toggle FullScreen

[mattiLeBlanc]

Feature Description

I am creating my own controls to Start (playVideo) and Pause (pauseVideo( a video and I would also like to be able to add a fullscreen button outside of the youtube-player component.
There seems to be no function available for it and I also can't requestFullscreen on the iframe.
Is there away, maybe via postMessage to tell the iframe to go trigger fullscreen?
If not, can this be provided?

The Youtube API doesn't mention anything. So I guess it is not possible.

Use Case

Toggle fullscreen when youtube controls are disabled, outside of the youtube component.

We want to use it on a Smart TV and using the D-pad arrows on the remote to go to the fullscreen icon is not very convenient. Being able to programatically go fullscreen should not be anymore insecure as allowing to Play or Pause, I think.

@crisbeto wow, that is quick.
I see you do the resize in the host of the youtube component. That was my solution to if this wasn't going be possible or picked up.
But I wasn't sure if it would have the same effect as if you click the fullscreen button within the iframe.
I will give a test, thanks.

Will this be available soon version 19.1.5?

@crisbeto I wanted to share this:

and when I hit fullscreen:

The iframe with the youtube video doesn't seem to resize. Is that something I can control?

okay, I was able to reset the size of the youtube player on resize, it goes to window.outerWidth and window.outerHeight, instead of what it was non fullscreen mode.
It works for the width, but not for the height. But that is probably something I can figure out.

**update: got it to work, using innerheight for height is better and I get it to fullscreen,
