问题
In an Ionic 2 app, I am trying to embed one youtube video using iframe. The code looks like this:
<iframe width="320" height="315" src="https://www.youtube.com/embed/VIDEOID?autoplay=1&controls=1" frameborder="0" allowfullscreen></iframe>
However when I navigate to the page I am getting this error. I can't find a good answer how to fix this.
XMLHttpRequest cannot load https://googleads.g.doubleclick.net/pagead/id. A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'https://www.youtube.com' is therefore not allowed access. The credentials mode of an XMLHttpRequest is controlled by the withCredentials attribute.
Not sure how to fix this. Any help/lead would be appreciated.
BTW, I am developing/testing in chrome browser developer tool.
Thanks,

You better add this to your config.xml:
<preference name="AllowInlineMediaPlayback" value="true"/>
<access origin="*" subdomains="true" />
Also make sure your android manifest has:
<application android:hardwareAccelerated="true" ...>

I have solved iframe problem by editing two html_sanitizer.js files. You ca find them under node_modules\@angular\platform-browser\src\security and node_modules\@angular\platform-browser\esm\src\security folders.
Open them and search for this line var BLOCK_ELEMENTS, insert iframe tag name and save. Now it should work, at least it works for me.

Try using enablejsapi=1 inside the source.
