How to Auto Play an embed YOU TUBE video, Using the new Embed code

At this point I think you already know how to grab the share embed code from a youtube video.
When you go to the video at the bootm you will see the "share" link then click embed you will get a code similar to this

<iframe width="560" height="315" src="//www.youtube.com/embed/5HN6PYI2hA0" frameborder="0" allowfullscreen></iframe>

all you have to do is add the following to the code: ?rel=0&autoplay=1

this is what it should look like:
<iframe width="560" height="315" src="//www.youtube.com/embed/5HN6PYI2hA0?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

does anyone have any Idea how to fix it have searched online and looked into it on my own but I'm not able to find a solution at this time. 

My solution was to upgrade to the PRO version of RSS POSTER
