As3 MP3 Player not loading

Question

So as I stated in this other post.. http://stackoverflow.com/questions/3700338/as3-mp3-player-loads-when-opened-locally-but-doesnt-show-up-at-all-on-my-server ..my MP3 Player is not loading online, but works perfectly on my local computer...

I was messing around with filse today and I finally got flash to give me an error...Could this be why the MP# player does not load online? heres the error

TypeError: Error #2007: Parameter text must be non-null.
 at flash.text::TextField/set text()
 at Mp3Player_fla::MainTimeline/id3Handler()

By the way I have the MP3 on its own swf. Its being called by the main swf...If I place all the code into the main swf could it possibly work? that shoudnt make a difference, but maybe becuause im loading large movies as the backgrounds and many other swf's at the same time, its messing it up?!

Answer 1

Your bug is in the id3Handler function. It appears you are trying to set the value of a text field there to null. If you cant figure it out, post the code for id3Handler and I'll give you some more info. Likely something hasn't loaded yet.

Answer 2

You could try to catch the error in the id3Handler , in case the id3 tags are not defined

function id3Handler(evt:Event):void {

    try{

      songInfo.text = /*song.id3.artist + ": " +*/ song.id3.songName;

   }catch(e:Error)
   {
      trace(e );

      //or...
      songInfo.text = "No name"
   }
}

although , you may well have a security issue , id3 info would be returned in such case. do you use a crossdomain policy file?

Extract from the Sound class docs:

Certain operations dealing with sound are restricted. 
The data in a loaded sound cannot be accessed by a file in a different domain 
unless you implement a cross-domain policy file. 
Sound-related APIs that fall under this restriction are 
Sound.id3 , 
SoundMixer.computeSpectrum(), 
SoundMixer.bufferTime, 
and the SoundTransform class.

Edit:

Here's a very permissive policy file, copy it , save it to a file and name the file

crossdomain.xml

then upload it to the root folder of your site, for instance for example.com

http://example.com/crossdomain.xml

  <?xml version="1.0"?> 
  <!DOCTYPE cross-domain-policy SYSTEM      
  "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd"&gt;
      <cross-domain-policy> <site-control permitted-cross-domain-policies="all"/> 
      <allow-    access-from domain="*" secure="false"/> 
      <allow-http-request-headers-from domain="*"   headers="*" secure="false"/>
 </cross-domain-policy>

If this works, read this article

and see how you can secure your site with the crossdomain policy file
