<script type="text/javascript">
jwplayer("myElement").setup({
image: "test.png",
sources: [{
file: 'http://www52.uptobox.com/stream/2ils3p70fd/360/0',
label: "360p"
},{
file: 'http://www52.uptobox.com/stream/2ils3p70fd/480/0',
label: "480p"
},{
file: 'http://www52.uptobox.com/stream/2ils3p70fd/720/0',
