Re: [flexcoders] Re: Buffer progress bar for streaming FLV

[Abdul Qabiz]

Hi,With VideoDisplay, you don't need to use onEnterFrame or any external Timer instance. Just subscribe to VideoDisplay's playheadUpdate event and do progress bar logic in event handler.-abdul

            Ok, Below is my updated "onEnterFrame()" method that updates a
progressBar component. It works great. Thanks again gang!

Now I'm going to try and get this working using the <mx:videoDisplay>
component. I'm not sure if I can get to its "netStream" object, so any
ideas/recommendations would be helpful and appreciated. 

Thanks!
Chris

			var loadpct:Number = Math.round(Math.ceil((stream.time/duration)*100));

			if(loadpct<=100)
			{
				bar.setProgress(loadpct,100);
				bar.label= "CurrentProgress" + " " + loadpct + "%";
				loadpct+=10;
			}
			if(loadpct>100)
			{
				loadpct=0;
			}
			trace("onEnterFrame: Duration: " + duration + " Time: " +
stream.time + " Loaded: " + loadpct + "%");
		}
