[Plugin: MediaElement.js – HTML5 Video & Audio Player] javascript code in category list

When viewing a Category list or Search results I see javascript code:

jQuery(document).ready(function($) {
$(‘#wp_mep_1′).mediaelementplayer({
m:1

,features: ['playpause','progress','current','duration','volume','tracks','fullscreen']
});
});

But it is ok when viewing a single post.
