视频格式转换工具，用到ws.schild.jave,之前是用的it.sauronsoftware.jave,作者已经不维护了

视频格式转换工具，用到ws.schild.jave,之前是用的it.sauronsoftware.jave,作者已经不维护了 ，最近又看到了这个，算是它的升级版，所以自己摸索它的用法，也根据之前的方法一步步试的。

添加依赖：

核心依赖

        ws.schild
            jave-core
            3.0.1
       

系统平台的依赖，看你程序使用的是什么系统，两个都可以加，这个是为了使用包里提供的工具，没有这个会出现错误！
       
            ws.schild
            jave-nativebin-win64
            3.0.1
       
       
            ws.schild
            jave-nativebin-linux64
