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。

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;
public class CutVideoUtils {
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
