How to stop playing YouTube video in pop-up after closing it?

Question

YouTube

Is there any simple and not steamy way to stop the video in the pop-up after it is closed?
Videos are inserted in the simplest way, ie. like this

<iframe class="youtube-video" width="100%" height="400" src="https://www.youtube.com/embed/ym80poNoDFE" frameborder="0" allowfullscreen></iframe>

Yes, I know that there is an api, and that you can upload each video through this api, but it's long and complicated. And there are already a lot of vidos on the site and it’s not an option to contact each vidos through id in order to close it.
Maybe there is some kind, even a crutch solution?

Jquery:$('.video-block iframe').attr('src', '');

Answer 3

Try another modal window plugin like Cardboardbox . There is nothing to add, the video itself stops playing after closing.
