This code works for me in Moodle 2.6:
<div id="myElement">Loading the player...</div>
<script type="text/javascript">
jwplayer("myElement").setup({
playlist: [{
file: "http://www.example.org/draftfile.php/171/user/draft/927794117/Getting_Started.mp(four)",
image: "/assets/sintel.jpg",
tracks: [{
file: "http://www.example.org/draftfile.php/171/user/draft/927794117/Getting_Started.srt",
label: "English",
kind: "captions",
"default": true
},{
file: "http://www.example.org/draftfile.php/171/user/draft/927794117/Getting_Started.srt",
kind: "captions",
label: "Hungarian"
}]
}]
});
</script>
Please note to copy jwplayer under the root directory and add the following two lines into the <head> section of you theme:
<script src="/jwplayer/jwplayer.js" ></script>
<script>jwplayer.key="your_jwplayer_token_key";</script>
Also turn off QuickTime player on the SITE ADMINISTRATION / APPEARANCE / MEDIA EMBEDDING page.
Cheers
