问题
I know its said in Embed YouTube Video with No Ads that it is up to the content owner if ads are shown or not.
However, I think there must be a workaround if you use a YouTube video as background in HTML5.
I discovered this website http://www.lifealignmentor.com/ after checking the source code I realized its using this YouTube video. The video on YouTube has ads enabled. However on the website http://www.lifealignmentor.com/ I never saw the ads.
So is the website using a forbidden hack or is there actually a way to embed a YouTube video as background without seeing the ads?
I don't know if it helps, but I also found that the website is using the Onetone MageeWP Theme.
