1.AVProMovieCapture插件下載
沒什么好說的，搞到安裝包之后，直接往項目中拉就行。
2.操作面板配置
（1）在Hierarchy創建一個空物體，上面添加Capture From Camera和Camera Selector兩個插件
（2）Camera Selector常用屬性
?屬性：Select By
·其中Highest Depth Camera表明使用深度最大的攝像機作為錄制攝像機，也就是Priority值最大的就是錄制攝像機。
· 其中Tag和Name表明，下面一行中輸入哪個攝像機的Tag/Name就使用哪個攝像機錄制
·其中 Manual表明直接以點擊右側圓圈來選擇，或者拖拽攝像機放入的方式來選擇錄制攝像機
（3）CaptureFromCamera
·CaptureFromCamera部分
首先需要將Capture對象拖入Camera Selector屬性欄中
?Resolution是視頻的尺寸
·output部分
3.代碼控制開始錄制、攝像機切換和結束錄制?
