How to stop youtube video when another youtube video starts playing?

Question

JavaScript

There is a slider with videos that are inserted into an iframe.
It is necessary to stop the already playing video when you turn on any other.
Tried like this

$('.video .slides li').change(function(){
    $('video').contentWindow.postMessage('{"event":"onclick","func":"pauseVideo","args":""}', '*');
  });

Did not help.
Thanks in advance!
