the bitrate is a property of an event object received by the metadataevent. so, you can just "read" it by listening for the metadataevent.

Thank you for replay. i'm working with live player.

i calculating kb from 'netstream.info' on every 10 sec.

now i had a problem. below script is showing total Kilobits on every 10 sec.

(like 1st time: 2695, 2nd time: 4882, 3rd time:7069)

but i want how much 'kb' in 10 sec.

i know solution is " totalKb - lastTime Kb result".

But i don't know how to calculate in this code.

var totalKb:Number;

function videoInfo():void
{
totalKb = ((ns.info.byteCount* 8) / 1024);
trace (totalKb);
}

var myInterval:uint = setInterval (videoInfo, 10000);

that's not the bitrate. you want to determine the download rate.

for that use:

var previouslyExecuted:Boolean;
if(!previouslyExecuted){
previouslyExecuted=true;
var totalKb:Number;
var previousTotalKb:Number=0;
var myInterval:uint;
}

function videoInfo():void
{
totalKb = ((ns.info.byteCount* 8) / 1024);
trace (totalKb-previousTotalKb);
previousTotalKb=totalKb
}

clearInterval(myInterval);
myInterval = setInterval (videoInfo, 10000);

you're welcome.

p.s. if you also want the bitrate, use the metadataevent. exactly how you do that depends on whether you're using netstream or an flvplayback component.

{
          totalKB = ((ns.info.byteCount* 8)/1024);
          trace (totalKB - previousTotalKb);
          previousTotalKb = totalKB;

if you want to send totalKB-previousTotalKb to your js function use:

function videoInfo():void
{
          totalKB = ((ns.info.byteCount* 8)/1024);
          trace (totalKB - previousTotalKb);
flash.external.ExternalInterface.call("sendToJS", totalKB-previousTotalKb);
          previousTotalKb = totalKB;

}

clearInterval(myInterval);
myInterval = setInterval(videoInfo, 10000);
