Hi shree123,
I think a possible solution to your problem will be to load the image from the web to a different Image object and then swap the display, something like:


<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" cachePolicy="auto">
<mx:Script>
<![CDATA[
import flash.utils.setInterval;
import flash.utils.setTimeout;

private var currentImage:int=0;

private function afterImage():void
{
if (currentImage == 0)
{
image1.addEventListener(Event.COMPLETE,swapImages) ;
image1.addEventListener(Event.COMPLETE,swapImages) ;
image1.load("http://192.168.1.68/Jpeg/CamImg.jpg");
} else {
image0.load("http://192.168.1.68/Jpeg/CamImg.jpg");
}
}

private function swapImages(event:Event):void
{
if (currentImage == 0)
{
image1.visible = true;
image0.visible = false;
} else {
image0.visible = false;
image1.visible = true;
}
}
]]>
</mx:Script>
<mx:Canvas>
<mx:Image id="image0" initialize="setInterval(afterImage,10000);" source="http://192.168.1.68/Jpeg/CamImg.jpg">
<mx:Image id="image1" visible="false">
</mx:Image>
</mx:Canvas>
</mx:Application>


I didn't try it but I think it should work...

Have fun !!!

shree123 - did you ever figure out the flicker. I tested the example above and still had the same problem. I think the idea is right there's just something missing.

Thanks in advance for any help!

Did you guys get this solved?

I'm newbie. So correct me if the code is wrong or not efficient.

But, this thing works fine for me.

...........
private static var count = 0;
...........
function setup(){
var my_mcl:MovieClipLoader = new MovieClipLoader();
var img_mc_0:MovieClip = _root.createEmptyMovieClip("img_mc_0", 10);
var img_mc_1:MovieClip = _root.createEmptyMovieClip("img_mc_1", 20);
..............
setInterval(updateScreen, 500, my_mcl, img_mc_0, img_mc_1);
}

function updateScreen(my_mcl, img_mc_0, img_mc_1){
if ((count % 2) == 0)
my_mcl.loadClip(_currentCamURL, img_mc_0);
else
my_mcl.loadClip(_currentCamURL, img_mc_1);

count++;
}
