Unity——播放视频

注：此方法播放视频仅支持ogv格式。

由于此播放视频的方法只支持ogv格式视频，而我们常见的视频格式大多是mp4、flv、avi等格式。所以我们需要对视频进行格式转换。

而格式转换所使用的工具为：Theora Converter .NET

将需要转换的视频拖入箭头指向区域，完成转换输出配置后，点击start即开始转换格式。

将转换好的视频文件放入资源库里，创建视频管理类

在Unity中使用NGUI插件创建名为Movie的UIPanel组件。

将视频管理类脚本挂在组件上。

创建Main方法：

using UnityEngine;using System.Collections;public class main1 : MonoBehaviour {    private MovieManage mm;// Use this for initializationvoid Start () {        mm = GameObject.Find("Movie").GetComponent<MovieManage>();        mm.PlayMovie("120");}// Update is called once per framevoid Update () {}}
