Unity编辑器环境下录屏，并制作播放器播放视频

版权声明：转发，使用请留言告知 https://blog.csdn.net/qq_37310110/article/details/86502890

工程源码，插件资源地址：https://download.csdn.net/download/qq_37310110/10920054

一.录屏工具导入（Recorder）

把recorder导入unity后，Tools>Recorder> Video打开录屏设置界面

把Input跟OutPut的参数设置一下，不要忘了还有输出视频的类型，帧率等

最后点击StartRecording就会运行工程并录制mainCamera视角也即是Game界面的画面

二.制作视频播放载体

1.新建RawImage，RenderTexture

2.在RawImage上添加VideoPlayer组件，并分别拖入创建的RenderTexture

三.编写播放器脚本
