サンプル↓動画ファイルパス書き換えてタイトルシーンとかじゃない3Dシーンで実行してみてー
using UnityEngine;
using UnityEngine.Video;
public class GameObjectListMacro
{
public static void MacroMain()
{
System.Console.WriteLine("--- VideoPlayer Sample ---");
var camera = new GameObject("VideoPlayer").AddComponent<Camera>();
camera.rect = new Rect(0.7f, 0.7f, 0.3f, 0.3f);
camera.gameObject.AddComponent<AudioSource>();
var videoPlayer = camera.gameObject.AddComponent<VideoPlayer>();
videoPlayer.renderMode = VideoRenderMode.CameraNearPlane;
videoPlayer.isLooping = true;
videoPlayer.url = "../test.mp4"; // ←Koikatuフォルダ直下
videoPlayer.Play();
}
}

VideoPlayer.renderModeのMaterialOverrideやRenderTexture使えば
CubeやQuadで3D空間にスクリーン作ったりも出来そうすね
