Media Embed

Hello all,
I want to add MediaEmbed plugin to my CKEditor which is on my website. I'm using PHP version to add this tool. My code is:

$ckeditor = new CKEditor();
$ckeditor->basePath = '/include/ckeditor/';
if(!isset($_GET['index2'])) $ckeditor->config['baseHref'] = "http://gieromaniak.pl"; else $ckeditor->config['baseHref'] = "http://gieromaniak.pl/liga";
$ckeditor->config['language'] = "pl";
$ckeditor->config['skin'] = "office2003";
$ckeditor->config['height'] = "350px";
$ckeditor->config['extraPlugins'] = "MediaEmbed";
$ckeditor->config['toolbar'] = array(
  array('Source','-','Undo','Redo','-','Templates'),
  array('Cut','Copy','Paste','PasteText','PasteFromWord','-', 'SpellChecker', 'Scayt','-','Subscript','Superscript','-','TextColor','BGColor', 'MediaEmbed'),
  array('Find','Replace','-','SelectAll','RemoveFormat'),
  array('Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton', 'HiddenField'),
  array('Bold','Italic','Underline','Strike','-','Outdent','Indent','Blockquote','CreateDiv'),
  array('NumberedList','BulletedList'),
  array('JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'),
  array('BidiLtr', 'BidiRtl' ),
  array('Link','Unlink','Anchor'),
  array('Image','Flash','Table','HorizontalRule','SpecialChar','PageBreak'),
  array('Styles','Format','Font','FontSize'),
  array('Maximize', 'ShowBlocks','-','About')
);
$ckeditor->editor('tresc', $wyswietl['tresc']);
