1、安装ffmpeg

https://ffmpeg.org/download.html#build-windows
下载windows可执行版
解压到服务器 D:\ffmpeg-6.1

2、复制video-thumbnail-context.xml和video-transformation-context.xml到D:\alfresco-community\tomcat\shared\classes\alfresco\extension

3、在D:\alfresco-community\tomcat\shared\classes\alfresco-global.properties中增加以下配置：
