java 获取视频的时长、大小、格式等信息

1、最近有一个小的视频处理需求，根据传入视频的url获取视频的时长、大小、格式等信息。下面将记录一下：

package Void;

/**

* @Description:获取视频宽高大小时间工具类

*/

import it.sauronsoftware.jave.Encoder;

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import java.math.BigDecimal;

import java.math.RoundingMode;

import java.nio.channels.FileChannel;

import java.util.HashMap;

import java.util.Map;

public class VoidUtils {

public static void main(String[] args){

File source = new File("http://flv4.people.com.cn/videofile3//CCTV1/2018/1/14/CCTV1_1500000_20181114_30322514_0_113_android_l.mp4");

Encoder encoder = new Encoder();

FileChannel fc= null;

String size = "";

try {

it.sauronsoftware.jave.MultimediaInfo m = encoder.getInfo(source);

long ls = m.getDuration();

System.out.println("此视频时长为:"+ls/60000+"分"+(ls)/1000+"秒！");

//视频帧宽高

System.out.println("此视频高度为:"+m.getVideo().getSize().getHeight());

System.out.println("此视频宽度为:"+m.getVideo().getSize().getWidth());

System.out.println("此视频格式为:"+m.getFormat());

FileInputStream fis = new FileInputStream(source);

fc= fis.getChannel();

BigDecimal fileSize = new BigDecimal(fc.size());

size = fileSize.divide(new BigDecimal(1048576), 2, RoundingMode.HALF_UP) + "MB";

System.out.println("此视频大小为"+size);

}catch (Exception e) {

e.printStackTrace();

}finally {

if (null!=fc){

try {

fc.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

}

/**

* @param path

* @return Map

*/

public static Map getVoideMsg(String path){

Map map = new HashMap();

File file = new File(path);

Encoder encoder = new Encoder();

FileChannel fc= null;

String size = "";

if(file != null){

try {

it.sauronsoftware.jave.MultimediaInfo m = encoder.getInfo(file);

long ls = m.getDuration();

FileInputStream fis = new FileInputStream(file);

fc= fis.getChannel();

BigDecimal fileSize = new BigDecimal(fc.size());

size = fileSize.divide(new BigDecimal(1048576), 2, RoundingMode.HALF_UP) + "MB";

map.put("height", m.getVideo().getSize().getHeight());

map.put("width", m.getVideo().getSize().getWidth());

map.put("format", m.getFormat());

}catch (Exception e) {

e.printStackTrace();

}finally {

if (null!=fc){

try {

fc.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

}

return map;

}

}

该工具类需要的依赖：

it.sauronsoftware

jave

1.0.2

system

${project.basedir}/src/main/resources/lib/jave-1.0.2.jar

commons-codec

commons-codec

1.10

org.apache.httpcomponents

httpclient

4.3.1

其中jave-1.0.2.jar 这个maven中没有 ，需要自己下载：

下载后在resource下创建lib放在里面

此时因为是外部包 不是maven自带的需要scope内system

${project.basedir}/src/main/resources/lib/jave-1.0.2.jar为项目中jar的路径

it.sauronsoftware

jave

1.0.2

system

${project.basedir}/src/main/resources/lib/jave-1.0.2.jar

当scope为system的时候打包不会自动打包进去的，所以要添加一个参数才能打包进去的

org.springframework.boot

spring-boot-maven-plugin

true
