ActionScript 3.0 :: Flv Length/creating A Seek Bar?

I'm using the following code to load a flv:
 
var connection:NetConnection = new NetConnection();var stream:NetStream;var videoMain = new Video(600,340);var metaObj:Object = new Object();
function onMetaData(data:Object):void{}

[Code].....
 
I can create play/pause funtionality just fine with stream.play(); and stream.pause();, but I also want to have a seek bar for the user to scrub. I'm just starting this, and I think I can do it once I figure out how to call the flv total length and link it to a custom seek bar movieclip.   So is there a way to call on the total length of a flv file?
 
such as:
 
var videoLength:uint = videoMain.length;
