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

        <dependency>

代码

不废话，上代码。

import cn.hutool.core.util.IdUtil;
import com.google.common.base.Joiner;

public class CutVideoUtils {
  /**
   * 剪切视频
   *
   * @param inputVideoPath 输入视频地址
   * @param outputDir 输出目录

   * @param duration 持续时间，单位为：秒

   */
  public static String cut(
      String inputVideoPath, String outputDir, String startTime, Integer duration)
      throws Exception {
    List<String> 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
