Reload Source of html5 video tag doesn't work on chrome

on an website I have a simple video player tag and a list of videos. Onclick to an element of the videolist I change the poster and src attribute of the video tag an den src and type of the source-tag inside the video tag. This all works fine in FF and IE but it don't works in chrome.

VideoTag

<video id='video' class='video-js vjs-default-skin' controls preload='none' width='640' height='320' poster='./poster/dummy.png' data-setup='{}' preload='none'>
    <source src='./video/BeHappyToBeAlive.mp4' type='video/mp4'>
    <track kind='captions' src='demo.captions.vtt' srclang='en' label='English'></track><!-- Tracks need an ending tag thanks to IE9 -->
    <track kind='subtitles' src='demo.captions.vtt' srclang='en' label='English'></track><!-- Tracks need an ending tag thanks to IE9 -->
    Your Browser does not support video tag. Please update your Browser.
</video>

JavaScript

$(document).ready(function(){

var videoChanging = false;

function changeVideo(videoTag) {

    var video = videoTag.children().first();
    var src = video.children('source');
    var title = video.parent().find('h3').html();
    var description = video.parent().find('p').html();
    var poster = video.attr('poster');
    var source = video.children().first().attr('src');
    var mainVideo = $('#video_html5_api');
    var mainVideoBox = $('#video');
    mainVideo.children('source').remove();
    mainVideo.prepend(src.clone());
    mainVideo.attr('poster', poster);
    mainVideo.attr('src', source);
    mainVideoBox.parent().find('h3').html(title);
    mainVideoBox.parent().find('p').html(description);
    document.getElementById('video_html5_api').load();
    videoChanging = false;
    setTimeout(function(){
        document.getElementById('video_html5_api').play();
    }, 200);
}

$('.videoListItemBox > a ').on('click', function () {

    if( videoChanging ){
        return;
    }

    document.getElementById('video_html5_api').pause();
    var video = $(this);
    videoChanging = true;
    var changeMovieCallback = function(){ changeVideo( video ); }
    var t = setTimeout(changeMovieCallback, 200);

});

});

When I add an alert to the beginn of the changeVideo(videoTag) function it will works fine in chrome. Can somebody explain my why and give me a solution to fix this problem?

This reason why the newly selected video is loading on alert message box is that it causes postback which is when the video is loaded.

It might be the preload='none' property on your video element. But it is hard to tell - your sample is too complex. How about something simple?

<video id='video' controls width='640' height='320'>
    Your Browser does not support video tag. Please update your Browser.
</video>

<div class= "videoListItemBox">
  <a href="#" data-src="http://html5demos.com/assets/dizzy.mp4" 
    data-poster="http://lorempixel.com/640/320/">video 1</a>
  <a href="#" data-src="http://techslides.com/demos/sample-videos/small.mp4" 
    data-poster="http://lorempixel.com/640/320/">video 2</a>
<div>

code:

$(function(){
  $('.videoListItemBox > a ').on('click', function (e) {
    var link = $(this);
    $('#video')
        .attr('poster', link.data('poster'))
        .attr('src', link.data('src'))
        .get(0).play();
    e.preventDefault(); 
  });
});

Do note that *.mp4 files are not supported on all browsers, so you should expand your code to include *.webm files as a fallback.
