Java实现视频时间维度剪切的工具类

这篇文章主要为大家详细介绍了将视频按照时间维度进行剪切的Java工具类，文中的示例代码讲解详细，感兴趣的小伙伴可以跟随小编一起了解一下

前言

本文提供将视频按照时间维度进行剪切的Java工具类，一如既往的实用主义。

Maven依赖

         com.google.guavaguava30.1.1-jre org.bytedecojavacv-platform1.5.5 cn.hutoolhutool-all5.5.2

代码

不废话，上代码。

package ai.guiji.csdn.tools; import cn.hutool.core.util.IdUtil; import com.google.common.base.Joiner; import com.google.common.base.Splitter; import org.bytedeco.javacpp.Loader; import java.io.File; import java.util.Arrays; import java.util.List; /** @Author 剑客阿良_ALiang @Date 2022/12/27 9:23 @Description: 视频剪切工具 */ public class CutVideoUtils { /** * 剪切视频 * * @param inputVideoPath 输入视频地址 * @param outputDir 输出目录 * @param startTime 起始时间，格式：0:01、10:08 * @param duration 持续时间，单位为：秒 * @return 图片地址 * @throws Exception 异常 */ public static String cut( String inputVideoPath, String outputDir, String startTime, Integer duration) throws Exception { List paths = Splitter.on(".").splitToList(inputVideoPath); String ext = paths.get(paths.size() - 1); if (!Arrays.asList("mp4", "flv").contains(ext)) { throw new Exception("format error"); } String resultPath = Joiner.on(File.separator).join(Arrays.asList(outputDir, IdUtil.simpleUUID() + "." + ext)); String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class); ProcessBuilder builder = new ProcessBuilder( ffmpeg, "-ss", startTime, "-i", inputVideoPath, "-t", String.valueOf(duration), "-c:v", "copy", "-c:a", "copy", "-y", resultPath); builder.inheritIO().start().waitFor(); return resultPath; } public static void main(String[] args) throws Exception { System.out.println( cut( "E:\\360MoveData\\Users\\huyi\\Desktop\\3333333.mp4", "E:\\360MoveData\\Users\\huyi\\Desktop\\", "0:10", 5)); } }

代码说明：

1、cut方法参数分别为输入视频路径、输出临时目录、剪切起始点、剪切持续时间。

2、起始时间的格式要注意，给了几个格式样式：0:01、10:11，前面为分钟后面为秒。

3、对文件后缀格式做了校验，可以按照需求自行调整。

4、剪切的时间不要超过视频时长。

验证一下

准备的视频信息如下
