How to stop a video in a YouTube slider when moving to the next one?

Question

YouTube

Tell me, pliz, I've been banging my head for several days.
As in this example of redwood.com.ua - where the video slider
is, you turn on the video from YouTube, it plays, but when you switch to the next video clip in the slider and click play, a cacophony begins, because. the previous video did not stop.
