1.AVProMovieCapture插件下载

没什么好说的，搞到安装包之后，直接往项目中拉就行。

2.操作面板配置

（1）在Hierarchy创建一个空物体，上面添加Capture From Camera和Camera Selector两个插件

（2）Camera Selector常用属性

 属性：Select By

·其中Highest Depth Camera表明使用深度最大的摄像机作为录制摄像机，也就是Priority值最大的就是录制摄像机。

· 其中Tag和Name表明，下面一行中输入哪个摄像机的Tag/Name就使用哪个摄像机录制

·其中 Manual表明直接以点击右侧圆圈来选择，或者拖拽摄像机放入的方式来选择录制摄像机

（3）CaptureFromCamera

·CaptureFromCamera部分

首先需要将Capture对象拖入Camera Selector属性栏中

 Resolution是视频的尺寸

·output部分

3.代码控制开始录制、摄像机切换和结束录制
