使用AVPro Video 加载视频第一秒的图片
原理：使用AVPro Video插件的MediaPlayer
mediaPlayer.OpenMedia(new MediaPath(url链接, MediaPathType.AbsolutePathOrURL), false);
然后等待一定时间
使用ExtractFrame截取视频
Texture2D texture2D = mediaPlayer.ExtractFrame(null, 1);
UI效果：
点击图片进行播放，在点击一下关闭播放

yield return new WaitForSeconds(0.5f);
Debug.Log("结束等待0.3秒, i = " + i);
Texture2D texture2D = mediaPlayer.ExtractFrame(null, 1);
if (texture2D == null)
{
Debug.LogWarning($"需要调整等待时间 i = {i} url = {urls[i]}");
continue;
}
GameObject video = Instantiate<GameObject>(VideoPlayerPre);
video.SetActive(true);
video.transform.SetParent(scrollRect.content);
video.GetComponent<Image>().sprite = Sprite.Create(texture2D, new Rect(0, 0, texture2D.width, texture2D.height), new Vector2(0.5f, 0.5f));

UI
1.创建一个空对象并添加TestAVPro(自己写的脚本)
2.创建Scroll View
3.给Scroll View 的Content添加Grid Layout Group 和 Content Size Fitter组件，按需调整里面参数
4创建MediaPlayer和displayUGUI组件
7.一个工具类型,给UI添加点击事件
using UnityEngine;
using UnityEngine.EventSystems;
public class EventTriggerListener : EventTrigger
{
public delegate void voidDelegate(GameObject obj);
public voidDelegate OnBtnDown;
public voidDelegate OnBtnUp;
public voidDelegate OnEnter;
public voidDelegate OnExit;
public voidDelegate OnStay;
public voidDelegate OnClick;
public voidDelegate OnDoubleClick;
private bool isEnter = false;
public void Update()
{
if (isEnter)
{
if (OnStay != null)
{
OnStay(gameObject);
}
}
}
public static EventTriggerListener Get(GameObject obj)
{
EventTriggerListener eventTriggerListener = obj.GetComponent<EventTriggerListener>();
if (eventTriggerListener == null)
{
eventTriggerListener = obj.AddComponent<EventTriggerListener>();
}
return eventTriggerListener;
}
private bool isTwo = true;
private bool isOver = true;
public override void OnPointerDown(PointerEventData eventData)
{
if (OnBtnDown != null)
{
OnBtnDown(gameObject);
}
isTwo = !isTwo;
if (!isOver)
{
return;
}
isOver = false;
Invoke("SelectClick", 0.3f);
}
public void SelectClick()
{
if (isTwo)
{
if (OnDoubleClick != null)
{
OnDoubleClick(gameObject);
}
}
else
{
if (OnClick != null)
{
OnClick(gameObject);
}
}
isTwo = true;
isOver = true;
}
public override void OnPointerUp(PointerEventData eventData)
{
if (OnBtnUp != null)
{
OnBtnUp(gameObject);
}
}
public override void OnPointerEnter(PointerEventData eventData)
{
if (OnEnter != null)
{
OnEnter(gameObject);
}
isEnter = true;
}
public override void OnPointerExit(PointerEventData eventData)
{
if (OnExit != null)
{
OnExit(gameObject);
}
isEnter = false;
}
}
