Unity 5 2d how to add a video (android)?

[wushu_1]

so i tried the handheld.playfullscreenmovie but all i see when i run it is white screen. here's what i did

public class splashy : MonoBehaviour {

// Use this for initialization
void Start () {
    splashyVoid();
}

// Update is called once per frame
void Update () {

}

void splashyVoid()
{
    Handheld.PlayFullScreenMovie("supersplashyyy.mp4", Color.black, FullScreenMovieControlMode.Hidden);
}
}

im completely new to unity. thanks for answering this.
