Refused to display in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'

I found a better solution, maybe it can help somebody replace "watch?v=" by "v/" and it will work

var url = url.replace("watch?v=", "v/");

O.K. after spending more time on this with the help of this SO post

Overcoming "Display forbidden by X-Frame-Options"

I managed to solve the issue by adding &output=embed to the end of the url before posting to the google URL:

var url = data.url + "&output=embed";
window.location.replace(url);

Try to use

https://www.youtube.com/embed/YOUR_VIDEO_CODE

You can find all embeded code in 'Embeded Code' section and that looks like this

<iframe width="560" height="315"  src="https://www.youtube.com/embed/YOUR_VIDEO_CODE" frameborder="0" allowfullscreen></iframe>

They have set the header to SAMEORIGIN in this case, which means that they have disallowed loading of the resource in an iframe outside of their domain. So this iframe is not able to display cross domain

enter image description here

For this purpose you need to match the location in your apache or any other service you are using

If you are using apache then in httpd.conf file.

  <LocationMatch "/your_relative_path">
      ProxyPass absolute_path_of_your_application/your_relative_path
      ProxyPassReverse absolute_path_of_your_application/your_relative_path
   </LocationMatch>

If you are using iframe for vimeo, change the url from:

https://vimeo.com/63534746

to:

http://player.vimeo.com/video/63534746

It works for me.
