YouTube full screen background not working in YTplayer

I am using the YTplayer plugin for YouTube full screen player into this website Breathe the tab!

• I have provided the code with helpful links! I think the code is correct!

• Please help me figure out why autoplay is not working?
• where is my code having error?

                        <p>Travel is more than the seeing of sights; it is a change that goes on, deep and permanent, in the ideas of living.</p>
                    </div>
                </div>
