1.在 maven 中引入依赖

         <dependency>
            <groupId>ws.schild</groupId>
            <artifactId>jave-all-deps</artifactId>
            <version>2.5.1</version>
        </dependency>  

2.使用工具类

 import ws.schild.jave.Encoder Exception ;
import ws.schild.jave.MultimediaInfo;
import ws.schild.jave.MultimediaObject;

import  java .io. File ;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.nio.channels.FileChannel;

public class AudioVideoUtil {

    /**
     * 获取音视频的大小
     * @param filePath
     * @return
     */
    public static Long getSize(String filePath) {
            FileChannel fc= null;
            try {
                FileInputStream fis = new FileInputStream(filePath);
                fc= fis.getChannel();
                Long videoSize=fc.size();
                return videoSize;
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                try {
                    fc.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            return  null;
        }

    /**
     * 获取音视频的时长
     * @param filePath
     * @return
     */
    public static  Long getTime(String filePath){
            try {
                MultimediaObject instance=new MultimediaObject(new File(filePath));
                MultimediaInfo result=instance.getInfo();
                Long videoTime=result.getDuration()/ 1000;
                return videoTime;
            } catch (EncoderException e) {
                e.printStackTrace();
            }
            return null;
        }
}
