Chrome bug while using html5 video and fullpage.js. Any solution?

Question

On my project I'm using fullpage.js in the home page.

Then I want to add a video as background, however the video is ignoring the autoplay option and it doesn't start. but it does when you scroll down once and then up again.

It is working fine on firefox (and even on IE!).

You can see this behaviour on this codepen

chrome version: 60.0.3112.113 (Build oficial) (64 bits)

Anything I could add to my code to make it works, at least temporally?

Thanks a lot.

Answer 1

Add this statement at the end of the afterLoad callback. The video tag may be ready to autoplay, but the plugin is probably still rendering the sections to suit its needs. The video plays when the plugin is loaded, see demo.

$('video')[0].play();

// variables
var $header_top = $('.header-top');
var $nav = $('nav');



// toggle menu 
$header_top.find('a').on('click', function() {
  $(this).parent().toggleClass('open-menu');
});



// fullpage customization
$('#fullpage').fullpage({
  sectionsColor: ['#B8AE9C', '#348899', '#F2AE72', '#5C832F', '#B8B89F'],

  slidesNavigation: true,
  controlArrows: false,
  anchors: ['firstSection', 'secondSection', 'thirdSection', 'fourthSection', 'fifthSection'],
  menu: '#menu',

  afterLoad: function(anchorLink, index) {
    $header_top.css('background', 'rgba(0, 47, 77, .3)');
    $nav.css('background', 'rgba(0, 47, 77, .25)');
    if (index == 5) {
      $('#fp-nav').hide();
    }
    $('video')[0].play();// <=======================[ADD THIS]
  },

  onLeave: function(index, nextIndex, direction) {
    if (index == 5) {
      $('#fp-nav').show();
    }
  },

  afterSlideLoad: function(anchorLink, index, slideAnchor, slideIndex) {
    if (anchorLink == 'fifthSection' && slideIndex == 1) {
      $.fn.fullpage.setAllowScrolling(false, 'up');
      $header_top.css('background', 'transparent');
      $nav.css('background', 'transparent');
      $(this).css('background', '#374140');

        'opacity': 1,
        'transform': 'translateY(0)'
      });
    }
  },

  onSlideLeave: function(anchorLink, index, slideIndex, direction) {
    if (anchorLink == 'fifthSection' && slideIndex == 1) {
      $.fn.fullpage.setAllowScrolling(true, 'up');
      $header_top.css('background', 'rgba(0, 47, 77, .3)');
      $nav.css('background', 'rgba(0, 47, 77, .25)');
