Error When Streaming Using AS3

[Guest]

Hello Guys, I am trying to stream my webcam using AS3 code but I keep receiving this error message in the output panel when I run the application:

ArgumentError: Error #2126: NetConnection object must be connected.

at flash.net::NetStream/ctor()

at flash.net::NetStream()

At first I listen for the NetStatusEvent status and the connection succeded

But when i include the NetStream class I receive that annoying error. I think this is the relevant code. Any ideas why it isnt working?

import flash.net.NetConnection;
import flash.events.NetStatusEvent;
import flash.net.NetStream;
import flash.media.Camera;
import flash.events.StatusEvent;
import flash.media.Video;
import flash.media.Microphone;

var nc:NetConnection = new NetConnection();

nc.addEventListener(NetStatusEvent.NET_STATUS, netStatus);

nc.connect("rtmfp://localhost/streamCamUrl");

var ns:NetStream = new NetStream(nc);

ns.publish("live", "recording");

function netStatus(event:NetStatusEvent):void{
switch(event.info.code){
 
  case "NetConnection.Connect.Success":
  trace("Connecting up...");
  break;
 
  case "NetConnection.Connect.Failed":
  trace("Unable to Connect");
  break;
 
  case "NetConnection.Connect.Rejected":
  trace("Ouchh!");
  break;
 
  case "NetStream.Connect.Success":
  trace("Thats great!");
  break;
 
  case "NetStream.Connect.Failed":
  trace("Livestream");
  break;
}
}

var cam:Camera = Camera.getCamera();
cam.setMode(520,320,15);
cam.setQuality(0, 80);
ns.attachCamera(cam);

cam.addEventListener(StatusEvent.STATUS, statusHandler);

var vid:Video = new Video();
vid.height = cam.height;
vid.width = cam.width;
vid.attachCamera(cam);

addChild(vid);

var mic:Microphone = Microphone.getEnhancedMicrophone();
mic.gain = 50;
mic.setSilenceLevel(0, 2000);
mic.framesPerPacket = 1;
mic.codec = SoundCodec.SPEEX;
ns.attachAudio(mic);

mic.addEventListener(ActivityEvent.ACTIVITY, this.onMicStatus);

function statusHandler(event:StatusEvent):void{
switch (event.code)
    {
        case "Camera.Muted":
            trace("User clicked Deny.");
            break;
        case "Camera.Unmuted":
            trace("User clicked Accept.");
            break;
    }
}

function onMicStatus(event:StatusEvent):void
{
    if (event.code == "Microphone.Unmuted")
    {
        trace("Microphone access was allowed.");
    } 
    else if (event.code == "Microphone.Muted")
    {
         trace("Microphone access was denied.");
    }
}

your ns.publish() method should not execute until your connection succeeds.  move that line of code.

Thanks kglad for your comment. I deleted out the ns.publish method when I executed the code I got a different error...

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

at Untitled_fla::MainTimeline/frame1()

Connecting up...

I have been tweaking around with the code but i still couldnt fix the issue. When I debugged the code this appeared in my output:

[SWF] C:\Users\\AppData\Local\Temp\Untitled-1.swf - 3420 bytes after decompression

*** Security Sandbox Violation ***

Connection to rtmfp://localhost/streamCamera halted - not permitted

-- Untrusted local SWFs may not contact the Internet.

SecurityError: Error #2028: Local-with-filesystem SWF file cannot access Internet URL rtmfp://localhost/streamCam.era

at flash.net::NetConnection/connect()

Any advice how to fix this?

[kglad]

you mean you moved that line of code, don't you?

[Guest]

Yes, Just clarifying I did remove the ns.publish. Then, I got a new error instead . Its confusing.

[kglad]

no, don't remove it. move it to your netconnection listener.

[Guest]

Sorry to be a nuisance. I hope I don't sound dumb but you mean move the ns.publish method to the netStatus function like this?

switch (info.code) {case "NetConnection.Connect.Success": 

                            ns.publish("live" "recording");

                            trace("CONNECTION SUCCES");
                            break;

[kglad]

yes, that should resolve the error message you mentioned.

[Guest]

No didnt work! I got the same argument error after putting that line of code in. Sorry, I must be a real pain. Do you put the ns constructor before or after the NetStatus function or doesnt it matter?

[kglad]

copy and paste your updated code.
