Java代码实现上传视频获取视频某一帧作为截图封面（二）

　　上一个文章讲了 Java代码实现上传视频获取视频某一帧作为截图封面的一种方法，现在讲述第二种方法。为什么要在这里讲这种方法呢？第一、这种方法生成的图片占用的空间更小第二、这种方法可以获取很多信息
　　一、根上一篇文章一样导入Maven项目所需要的依赖，这里不在复制，可以去上篇文章看一下
　　二、废话不多说直接上代码 package com.basic.common.utils;   import org.bytedeco.javacv.FFmpegFrameGrabber; import org.bytedeco.javacv.FrameGrabber; import org.bytedeco.javacv.Frame; import org.bytedeco.javacv.Java2DFrameConverter;

　　切记包一定要导对哦
　　下面就是测试代码   public void testPic1() throws IOException {         String s = VideoUtils2.fetchFrame(＂D:testdemotestdemo.mp4＂);           VideoUtils2.base64ToMultipart(s).transferTo(new
