How do you stop YouTube from playing other videos after one video ends?

I face many times this problem,when I embed my YouTube video after finish video come related video lists come. That go out form my site or my video links or playlist.

For this i have one solution :

check this red line box.when you embed YouTube video unchecked this checkbox. 

OR 

You have only embed code of video then you need some code in embed code.

add "?rel=0" after YouTube link 

E.g. 

< #iframe allow="autoplay; encrypted-media" allowfullscreen="" frameborder="0" height="315" src="https://www.youtube.com/embed/5i1jB-l_UlY?rel=0" width="560">

You can check from your side also.
