how to change the volume

[GoogleCodeExporter]

What steps will reproduce the problem?
1. play a stream
2. try to change the volume
3.

What is the expected output? What do you see instead?

Hi I am trying to change the volume (eventually using a volume slider)
the MP3StreamPlayer.soundChannel is read only, how to use soundTransform?

What version of the product are you using? What player environment did you
test in? What version?

latest one, in flash CS4.

Please provide any additional information below.

mp3streamplayer.soundChannel.soundTransform.volume = 0.5; // 50%

This is the code I am using (to test it):

import fly.sound.*
import fly.sound.shoutcast.*
import fly.sound.events.*

var ssp:MP3StreamPlayer = new MP3StreamPlayer() 
ssp.playStream("http://scfire-ntc-aa06.stream.aol.com:80/stream/1039")
ssp.soundChannel.soundTransform.volume = 0.0; // 50%

The error I receive is:

TypeError: Error #1009: Cannot access a property or method of a null object 
reference.

If you want to change the volume, try this:

var myPlayer:MP3StreamPlayer = new MP3StreamPlayer();;
var myChannel:SoundChannel = myPlayer.soundChannel;
var mySoundTransform:SoundTransform = myChannel.soundTransform;
mySoundTransform.volume = 0.5;
myChannel.soundTransform = mySoundTransform;

It won't work.  You can change wolume only after the playback is started. It 
can be done with this code:

var stream:MP3StreamPlayer = new MP3StreamPlayer();
stream.addEventListener(Event.COMPLETE, completeHandler);
stream.playStream('http://stream_address/');

function completeHandler(e:Event)
{
    var stream:MP3StreamPlayer = e.target;
    var mySoundTransform:SoundTransform = stream.soundChannel.soundTransform;
    mySoundTransform.volume = Std.parseFloat(params.volume);
    stream.soundChannel.soundTransform = mySoundTransform;
}
