INTRODUCTION

Here we will decode an Ogg Theora file streaming from the internet onto a plane surface scripted in Unity 3d.

DISCUSSION

The fastest method to do this as of writing is to look here and then attach this to the camera in a new unity 3d scene.

FINDINGS

The Unity docs do not seem to show a C# source example, so in full Blue Peter (UK) style: Here is one I made earlier.

//============================================================================

// Author      : Divide To Infinity

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(GUITexture))]
[RequireComponent(typeof(AudioSource))]
public class WWWVideoTexture : MonoBehaviour
{
    public string url = "http://playground.html5rocks.com/samples/html5_misc/chrome_japan.ogv";
    IEnumerator Start()
    {
        WWW www = new WWW(url);
        MovieTexture movieTexture = www.movie;
        while (!movieTexture.isReadyToPlay)
        {
            yield return null;
        }
        
        GUITexture gt = GetComponent();
        gt.texture = movieTexture;
        transform.localScale = new Vector3(0, 0, 0);
        transform.position = new Vector3(0.1f, 0.25f, 0);

        gt.pixelInset = new Rect(0, 0, movieTexture.width / 2, movieTexture.height / 2);

        AudioSource aud = GetComponent();
        aud.clip = movieTexture.audioClip;
        movieTexture.Play();
        aud.Play();
    }
}
