WWW.movie never get ready to play ?

Hello there,

I'm trying to stream a movie from an external directory (on a distant server or on my computer). While I have no trouble retrieving the whole video, I can never get it to play because isReadyToPlay is always false.

At first, I thought it was a codec issue but it can't be it. When I import it in my project, it is not converted (since it's already OGG Theora) and it plays well.

Here's the slightly modified test code I found on the net :

 #define STREAMING
 
 using System;
 using UnityEngine;
 using System.Collections;
  
 [RequireComponent(typeof(AudioSource))]
 public class VideoStreamer : MonoBehaviour
 {
     public MovieTexture movieTexture;
     protected bool streamReady = false;
  
     void Start ()
     {
         
 #if STREAMING
         StartCoroutine(StartStream(@"C:\Users\mparent\Videos\teaser_ANTITRUST_FR_1.ogv"));
 #else    
         audio.clip = movieTexture.audioClip;
         audio.Play();
         movieTexture.Play();
 #endif
         
     }
     
 #if STREAMING
     
     protected IEnumerator StartStream (String url)
     {
         WWW videoStreamer = new WWW (url);
         movieTexture = videoStreamer.movie;
         audio.clip = movieTexture.audioClip;
  
         while (!movieTexture.isReadyToPlay) {
             if ( ! videoStreamer.isDone ) Debug.Log ( "Downloading !");
             else Debug.Log ( "Preparing stuff...");
             yield return 0;
         }
  
         Debug.Log("Start playback");
         audio.Play ();
         movieTexture.Play ();
         streamReady = true;
     }
     
 #endif
  
     void OnGUI ()
     {
         
 #if STREAMING
         if (streamReady) {
             GUI.DrawTexture (new Rect (0, 0, Screen.width, Screen.height), movieTexture);    
         }
 #else
         GUI.DrawTexture (new Rect (0, 0, Screen.width, Screen.height), movieTexture);  
 #endif
         
     }
 }

Anyone knows what's wrong here ? Thanks in advance for your answers.
