add autoplay for video in slick carousel

Question

I use slick carousel http://kenwheeler.github.io/slick/ on my page and now I need to add video with autoplay in it.
I use this code
HTML

<div class="main-slider" id="main-slider">
            <div>
                <div class="video-wrapper">
                    <video autoplay loop class="pageBackground-video">
                        <source src="/Content/video/332145276.mp4" type="video/mp4">
                    </video>
                </div>
            </div>
            <div>
                <div class="video-wrapper">
                    <video autoplay loop class="pageBackground-video">
                        <source src="/Content/video/332145276.mp4" type="video/mp4">
                    </video>
                </div>
            </div>          
        </div>

and script

$('#main-slider').slick({
      slidesToShow: 1,
      slidesToScroll: 1,
      autoplay: true,
      autoplaySpeed: 30000,
      dots: true,
      infinite: true,
      adaptiveHeight: true,
      arrows: false
  });

but autoplay doesn't work. Is there any way to make autoplay work?

upd I tried to use

$('#main-slider').on('afterChange', function(event, slick, currentSlide, nextSlide){
  var video = currentSlide.children('video').get(0).play();
});

but I get an error Uncaught TypeError: currentSlide.children is not a function because currentSlide it's just a number (0,1,etc). How to get current element?

upd2 I used this code and it works

$('#main-slider').on('afterChange', function(event, slick, currentSlide, nextSlide){
    $('#main-slider .slick-slide').find('video').get(0).pause();
    var video = $('#main-slider .slick-active').find('video').get(0).play();
});

but now autoplay work for all video perfectly but only after first slick changes. How to make it work for the first video after page only loaded.

upd3 I used this code

 var video = $('#main-slider .slick-active').find('video').get(0).play();

  $('#main-slider').on('afterChange', function(event, slick, currentSlide, nextSlide){
    $('#main-slider .slick-slide').find('video').get(0).pause();
    var video = $('#main-slider .slick-active').find('video').get(0).play();
});

and now all work as I want but I'm afraid my code is ugly (

You can use functions from the slick docs.

// On slide change, pause all videos
$('#main-slider').on('beforeChange', function(event, slick, currentSlide, nextSlide){
  $('video').each(function() {
    $(this).get(0).pause();
  });
});

// On slide chnage, play a video inside the current slide
$('#main-slider').on('afterChange', function(event, slick, currentSlide, nextSlide){
  if( $('.project-slide.slick-current').find('video').length !== 0) {
    $("#main-slider .slick-current video")[0].play();
  }
});
