1、导入maven依赖

<dependency><groupId>org.mp4parser</groupId><artifactId>isoparser</artifactId><version>1.9.41</version>
</dependency>

2、代码案例

import com.alibaba.fastjson2.JSON;
import org.mp4parser.IsoFile;import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.text.ParseException;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.temporal.ChronoUnit;
import java.time.temporal.TemporalAdjusters;
import java.util.*;public class Test {public static void main(String[] args) throws ParseException {long spsj = readDuration(Paths.get("C:\\Users\\Administrator\\Desktop\\ceshi.mp4"));System.out.println(spsj);}public static long readDuration(Path mp4Path) {if (Files.notExists(mp4Path) || !Files.isReadable(mp4Path)) {System.out.println("文件路径不存在或不可读 " + mp4Path);return 0;}try {IsoFile isoFile = new IsoFile(mp4Path.toFile());long duration = isoFile.getMovieBox().getMovieHeaderBox().getDuration();long timescale = isoFile.getMovieBox().getMovieHeaderBox().getTimescale();return duration / timescale;} catch (IOException e) {e.printStackTrace();return 0;}}
}

3、SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder”.

如果在运行过程中报错：SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

问题分析：
org.slf4j.impl.StaticLoggerBinder通常存在于slf4j-nop.jar和slf4j-simple.jar中，虽然项目maven中已引入了simple包，但依然存在报错。说明simple包未真正被加载。为了让包更好的加载，在依赖中添加type为jar后，问题得到解决。

<!-- 依赖软件版本 -->
