Question: How can I find out if jPlayer is playing?
I tried this `alert($.jPlayer.event.playing);` but it doesn't work.

Answer: 
I've not worked with Jplayer specifically, but playing around, this returned false if the media was playing and true if it wasn't.

```
$('#jquery_jplayer_1').data().jPlayer.status.paused

```
```
var duration = $('#jquery_jplayer_1').data("jPlayer").status.currentTime;

if(duration){
  // Source is loaded and playing 
}

```
