I am trying to build a flash player for my company's Shoutcast server, and have seen a few articles about it on the 'net, including this SO question here.
However, I can't seem to get the audio stream to actually play. It seems to be connecting alright, but calling stream.play() doesn't seem to do anything.
I have tried the code in the SO question I have linked to, and have also tried something similar to this (sorry i don't remember the exact syntax):
public function stream() {
private var url:URLREQUEST = "my.domain.com";
private var sStream:Sound = new Sound();
sStream.load(url);
sStream.play();
}
If anyone has any revelations for me I'd appreciate it.
I just posted a solution on this thread:
How to stream a shoutcast radio broadcast in Flash (Shoutcast Flash Player)
Did you try this - (corrected some typos in the code you posted)?
public function stream()
{
private var url:URLRequest = new URLRequest("my.domain.com/song.mp3");
private var sStream:Sound = new Sound();
sStream.load(url);
sStream.play();
}

I'm building an AIR application. Basically, what I'm looking to do is using navigateToUrl() to open a browser window, assign it a "name" and then, send variables to that newly opened window using the POST method.
EDIT : I need the window to be visible, this is why I absolutely need to use the navigateToUrl() function
I already know that I CAN'T DO something like this, that the AIR application will send the variables using the GET method...
var vars:URLVariables = new URLVariables();
vars.myVar = "Hello my friend";
var req:URLRequest = new URLRequest("http://example.com/my-page.php");
req.method = "POST":
req.data = vars;
navigateToURL(req);
Considering the amount of variables I have to send (multiline texts) I absolutely need to send my variables using the POST method else Internet Explorer is truncating the query string... Works fine in Firefox and Safari but unfortunately, we will always have (hope not!) to deal with IE..
So I was thinking something like this :
import flash.net.navigateToURL;
private var _timer:Timer;
protected function loadPage():void
{
var req:URLRequest = new URLRequest("http://example.com/my-page.php");
navigateToURL(req, "myPageName");
_timer = new Timer(3000, 1);
_timer.addEventListener(TimerEvent.TIMER, postVars);
_timer.start();
}
protected function postVars(event:TimerEvent):void
{
// I'm looking to send variables using the POST method to "myPageName"
// and possibly using URLVariables()??
_timer.stop();
}
Any idea Flex coders? THANKS!
I think what you're going to need to do is open up a page you have control over, then use ExternalInterface to inject the values into a hidden form and then execute the post operation in that page form.submit(), etc.
This can happen almost instantly and it will all appear very seamless to the end user.
This is a super newbie question on Flex. While I am a seasoned programmer, this is my first ever Flex application; please bear with me for my Flex codes.
I have a web service written in ColdFusion. In this web service, there are two functions; one is to return all the questions in a quiz and the other one is to return all the answer selections to the questions in a quiz.
[Bindable]
private var questionArray:ArrayCollection;
private var cfquiz:RemoteObject;
private function loadQuestions():void {
currentQuestionCounter = 0;
btnPrev.enabled = false;
btnNext.enabled = false;
cfquiz = new RemoteObject("ColdFusion");
cfquiz.source = "CFCertExam.cfquiz";
cfquiz.addEventListener(ResultEvent.RESULT, resultHandler);
}
private function resultHandler(event:ResultEvent):void {
questionArray = event.result as ArrayCollection;
txt1Questions.htmlText = questionArray.getItemAt(currentQuestionCounter).Question_Text;
btnNext.enabled = true;
}
I have the codes above. loadQuestions is called at creationComplete to retrieve the questions. Things are working fine. What I want to do is to call another function within the same web service, returnAnswers, to return the answer options for a question. Since I have cfquiz associated to the web service already, I was using cfquiz to call returnAnswers. However, there is an event listener associated to cfquiz already, resultHandler is being called when returnAnswers comes back with the results.
My questions are, first, is it possible to check which function returns the results within resultHandler? If so, how? And second, what is the best way to handle calls to multiple functions within the same web service?
Thanks in advance,
Monte
Yes you can. You need to specify a handler function for each method which in turn calls a different webservice.
The better way to do this is using AsyncToken and AsyncResponder instead of addEventListener, as following code.
tokenA = cfquiz.methodA();
tokenA.addResponder(new AsyncResponder(onResultForMethodA, onFaultMethodA));
tokenB = cfquiz.methodA();
tokenB.addResponder(new AsyncResponder(onResultForMethodB, onFaultMethodB));
tokenC = cfquiz.methodA();
tokenC.addResponder(new AsyncResponder(onResultForMethodC, onFaultMethodC));
or
tokenA = cfquiz.methodA();
var responderA:IResponder = new AsyncResponder(onResult, onFault, "methodA");
tokenB = cfquiz.methodB();
var responderB:IResponder = new AsyncResponder(onResult, onFault, "methodB");
tokenA.addResponder(responderA);
tokenB.addResponder(responderB);
private function onResult(evt:ResultEvent, token:Object):void {
if(token == "methodA" ) {
//logic for methodA
}
if(token == "methodB" ) {
//logic for methodB
}
}
I'm a little confused as I can't see where you are calling the actual web service function, for example from these examples, I am expecting to see:
cfquiz = new RemoteObject("ColdFusion");
cfquiz.source = "CFCertExam.cfquiz";
cfquiz.addEventListener(ResultEvent.RESULT, resultHandler);
cfquiz.myCFCFunctionCall(); /* where is this? */
Anyway, AFAIK you can create a new instance of the remote object and set that up to have it's own event listener.
Hope that helps.
I'm using Adobe Stratus (now renamed to Cirrus) to build a p2p application. Inside the application, I used NetStream.onPeerConnect callback function and expected it to be triggered every time when a peer is connected. However, it always failed with my friend A while strangely friend B managed to have the function called without any problem.
I was wondering what could be the cause to this issue?
Here are how the code pieces look like.
First of all, create a NetConnection.
netConnection = new NetConnection();
netConnection.addEventListener(NetStatusEvent.NET_STATUS, netConnectionHandler);
netConnection.connect(SERVER_ADDRESS+DEVELOPER_KEY);
Secondly, create NetStream upon NetConnection successfully connected.
private function netConnectionHandler(event:NetStatusEvent):void{
switch (event.info.code){
case "NetConnection.Connect.Success":
sendStream = new NetStream(netConnection, NetStream.DIRECT_CONNECTIONS);
sendStream.addEventListener(NetStatusEvent.NET_STATUS, netStreamHandler);
var sendObj:Object = new Object();
sendObj.onPeerConnect = function(subscriber:NetStream) : Boolean {
trace("[onPeerConnect] far id: " + subscriber.farID);
return true;
}
sendStream.client = sendObj;
sendStream.publish("file");
......
Thirdly, here's how I build the connection between two peers
receivedStream = new NetStream(netConnection, farId);
receivedStream.client = this;
receivedStream.addEventListener(NetStatusEvent.NET_STATUS, incomingStreamHandler);
receivedStream.play("file");
Please help enlighten me. Thanks!
It turns out my friend A is behind a symmetric NAT. I'm thinking to setup a TURN server for us to build a successful connection.
I have a simple video/chat application built in FLEX. I've created a groupSpecifier, netGroup and a NetStream for the different functionalities.
NetGroup is mainly used for the messaging (Posting) and keeping track of the users who enter.
NetStream is (or would be used) to control some functions like "start video, stop video" for everyone under the same group.
The most important functions I will post on here. The first is setupGroup.
private function setupGroup():void{
var groupspec:GroupSpecifier = new GroupSpecifier("vid"+GROUP_ID+"_sid_"+SESSION_ID);
groupspec.serverChannelEnabled = true;
groupspec.postingEnabled = true;
groupspec.multicastEnabled = true;
groupspec.ipMulticastMemberUpdatesEnabled = true;
trace("Groupspec: "+groupspec.groupspecWithoutAuthorizations());
netGroup = new NetGroup(nc,groupspec.groupspecWithoutAuthorizations());
netGroup.addEventListener(NetStatusEvent.NET_STATUS,netStatus);
netVideo = new NetStream(nc,groupspec.groupspecWithoutAuthorizations());
netVideo.addEventListener(NetStatusEvent.NET_STATUS,netStatus);
user = "user"+Math.round(Math.random()*10000);
}
The second is sendMessage
private function sendMessage():void{
var message:Object = new Object();
message.sender = netGroup.convertPeerIDToGroupAddress(nc.nearID);
message.user = txtUser.text;
message.text = txtMessage.text;
netGroup.post(message);
receiveMessage(message);
txtMessage.text = "";
}
And then startVideo
private function startVideo():void{
netVideo.send("publishVideo");
ns.togglePause();
}
There is another function called "publishVideo" which I hope would be called for the rest of the members in the group, but this is not happening. Most of this code is straight from the example Tom has provided from http://www.flashrealtime.com. Any help / suggestions would be appreciated!
p.s. I am not using group object replication because of the latency.
Answer is prosaically simple.
You need to start video with:
netVideo.publish("channel");
NetStream.send() is for invoking callback method on receiver NetStream.client object.

I'm looking for a way to find the status of a live stream through a VideoDisplay (or any other method really). I am interested to know if the stream is currently being published to or if the publisher has stopped. This is for a Flex/Flash ActionScript 3 project.
Is there a way to do this or is this ANOTHER oversight by adobe?
flex flash adobe adobe-flex actionscript
I've only found one solution, and that's using the NetStream object in combination with a video control.
The video control must be manually added to an
nsListen = new NetStream(nc);
nsListen.addEventListener(NetStatusEvent.NET_STATUS, nsListenHandler);
nsListen.play(streamname);
var v:Video = new Video();
v.attachStream(nsListen);
uicontrol.add(v);
Finally, the event status is returned in nsListenHandler:
private function nsListenHandler(e:Event):void
{
if(e is NetStatusEvent)
{
var nse:NetStatusEvent = NetStatusEvent(e);
if(nse.info.code == "NetStream.Play.Failed")
{
// Big error.
}
if(nse.info.code == "NetStream.Play.PublishNotify")
{
// Stream has just been published
}
if(nse.info.code == "NetStream.Play.UnpublishNotify")
{
// Stream has just been unpublished
}
trace(NetStatusEvent(e).info.code);
trace(NetStatusEvent(e).info.description);
}
}
Only this code wont do is tell you if a stream is already successfully being published to.
You can dig into NetStatusEvent events.
