Live streaming with rtsp

Hello,

I have a problem, I want to display a live video in a window but I have no video with the code below. I tried with the example of Unity: http://www.unity3d.com/webplayers/Movie/sample.ogg that works very well.

Have an idea or it is not possible? I have to use another way to use the live streaming?

// My code

//the GUI texture

 private GUITexture videoGUItex;
 
 //the Movie texture
 private MovieTexture mTex;
 //the AudioSource
 private AudioSource movieAS;
 //the movie name inside the resources folder
 public string movieName;

 private string url= "rtsp://my_AdresseIp";
 
 //WWW
 private WWW myWWW;
 
 void Awake()
 {
     
 }

 //On Script Start
 void Start()
 {
     //get the attached GUITexture
     videoGUItex = this.GetComponent<GUITexture>();
     //get the attached AudioSource
     movieAS = this.GetComponent<AudioSource>();

     myWWW = new WWW(url);

     //load the movie texture from the resources folder
     mTex = myWWW.movie; //(MovieTexture)Resources.Load(movieName);
     //set the AudioSource clip to be the same as the movie texture audio clip
     movieAS.clip = mTex.audioClip;
     //anamorphic fullscreen
     videoGUItex.pixelInset = new Rect(Screen.width / 2, -Screen.height / 2, 0, 0);

     //set the videoGUItex.texture to be the same as mTex
     videoGUItex.texture = mTex;
     //Plays the movie
     mTex.Play();
     //plays the audio from the movie
     movieAS.Play(); 
 }
