Add a Movie Texture to UI Button

Hello,

I´m trying to add a movie texture to a UI button I have. I have a method that plays and stops the video when the button is pressed. However I´m not able to get the video to show in my game view. Can anyone help me to make it show up?

This is the script attached to my button and my editor

 using UnityEngine;
 using System.Collections;
 
 [RequireComponent (typeof(AudioSource))]
 public class Video : MonoBehaviour {
     public MovieTexture movie;
     // Use this for initialization
     void Start () {
         renderer.material.mainTexture = movie as MovieTexture ;
         movie.Play ();
     
     }
 
 
     public void PlayStop(){
         if(movie.isPlaying){
             movie.Pause();
             
         }
         else{
             movie.Play();
             
         }
         
     }
 
 
 
 }
