一、搭建基础的视频显示UI（其中时间进度条、音量进度条、及其对应的显示文字UI可以不用搭建）

注意：要想实现鼠标移入显示进度条、音量和时间控件，需要给视频显示控件RawImage添加BoxCollider 2D碰撞体，且调整碰撞体大小为自己想要触发的区域即可。 

二、编写视频控制脚本

三、使用方法

 ①将该设备播放控制脚本（Ctrl_VideosOperation.cs）添加给视频显示组件（我这里是：Image_Videos (3)）

②新建一个空物体(取名：_TestVideosOperation)作为测试视频操作脚本的挂载物体（Test_VideosOpreation.cs）

③测试视频操作脚本的挂载物体（Test_VideosOpreation.cs）如下：

/****	Title："可视化" 项目*		主题：测试视频播放控制*	Description：*		功能：XXX*	Date：2019*	Version：0.1版本*	Author：Coffee*	Modify Recoder：*/using System.Collections;using System.Collections.Generic;using UnityEngine;using Control;using System.IO;using kernal;using Global;using UnityEngine.EventSystems;namespace TestInfo{	public class Test_VideosOpreation : MonoBehaviour    {        public GameObject showRawImage;                                         //显示面板        private Ctrl_VideosOperation _VideosOperation;                          //视频控制脚本               void Start()        {            if (showRawImage!=null)            {                _VideosOperation = showRawImage.GetComponent<Ctrl_VideosOperation>();            }            //获得本地的视频路径            string _VideoPath=@"C:\测试视频\第1章 基本概念清晰版.mp4";            _VideosOperation.satrtplay = _VideosOperation.LoadVideo(VideoPath);            _VideosOperation.LoadFirstPicture();        }        void Update()        {            //开始播放            if (Input.GetKeyDown(KeyCode.P))            {                _VideosOperation.Play();            }            //暂停播放            if (Input.GetKeyDown(KeyCode.L))            {                _VideosOperation.Pause();            }            //停止播放            if (Input.GetKeyDown(KeyCode.S))            {                _VideosOperation.Stop();            }        }           }//Class_end}

④运行测试，效果图如下：
