视频格式转换工具，用到,之前是用的,作者已经不维护了

视频格式转换工具，用到,之前是用的,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

        <groupId></groupId>
            <artifactId>jave-core</artifactId>
            <version>3.0.1</version>
        </dependency>

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！
        <dependency>
            <groupId></groupId>
            <artifactId>jave-nativebin-win64</artifactId>
            <version>3.0.1</version>
