Slick.js and html5 video autoplay and pause on video

Question

Is it possible to use slick.js with html5 self hosted videos, to play and pause a video without user interaction?

I currently have the following code to have a dual

Answer 1

Yes it can be done using JavaScript.
When the video slide becomes the currentSlide you need to:

1. pause the slider
2. play the video

You can do this using the slick.js event afterChange:

$('.sliderMain').on('afterChange', function(event, slick, currentSlide){
  if (currentSlide == 5) {
    $('.sliderMain').slick('slickPause');
    myVideo.play();
  }
});

You will also need to add an event listener for when to video ends in order to order the slider to continue. You can do so like this:

document.getElementById('myVideo').addEventListener('ended',myHandler,false);
function myHandler(e) {
    $('.sliderMain').slick('slickPlay');
}

If you're having trouble with this, please add a JSFiddle and I'll try help you there.

Edit: here's a working JSFiddle

$(document).ready(function() {
  $('.sliderMain').slick({
    slidesToShow: 1,
    slidesToScroll: 1,
    arrows: false,
    fade: true,
    asNavFor: '.sliderSidebar',
    autoplay: true,
    autoplaySpeed: 3000
  });
  $('.sliderSidebar').slick({
    slidesToShow: 5,
    slidesToScroll: 1,
    asNavFor: '.sliderMain',
    dots: false,
    centerMode: false,
    focusOnSelect: true,
    vertical: true,
    arrows: false
  });
  $('.sliderMain').on('afterChange', function(event, slick, currentSlide) {
    if (currentSlide == 5) {
      $('.sliderMain').slick('slickPause');
      theVideo.play();
    }
  });

  document.getElementById('theVideo').addEventListener('ended', myHandler, false);

  function myHandler(e) {
    $('.sliderMain').slick('slickPlay');
  }
});
