mp4在DrawTexture上播放

此脚本是挂在Plane下，要将Audio Sourse和Audio listener组件挂在此物体上才能正常播放视频。这两个组件挂在camera上无法播放视频。

using UnityEngine;
using System.Collections;

public class TestMp4B : MonoBehaviour {

//电影纹理
public MovieTexture mov;

void Start()
{

audio.clip = mov.audioClip;
audio.Play();
mov.Play();

//设置电影纹理播放模式为循环
mov.loop = true;

}

void OnGUI()
{
if(GUI.Button(new Rect ( 310,0,100,50),"2倍速播放"))
{
audio.pitch = 2f;
}

if(GUI.Button(new Rect ( 410,0,100,50),"1倍速播放"))
{
audio.pitch = 1f;
}

GUI.DrawTexture(new Rect(0,0,300,300),mov);

//绘制电影纹理
GUI.DrawTexture(new Rect(0, 0, Screen.width, Screen.height), mov, ScaleMode.StretchToFill);

if (GUILayout.Button("播放/继续"))
{
//播放/继续播放视频
if (!mov.isPlaying)
{
mov.Play();
}

}

if (GUILayout.Button("暂停播放"))
{
//暂停播放
mov.Pause();
}

if (GUILayout.Button("停止播放"))
{
//停止播放
mov.Stop();
}
}

}
