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;
/**
* @Author:psw
* @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<String, Object> getVoideMsg(String path){
Map<String, Object> map = new HashMap<String, Object>();
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：
<dependency>
<groupId>it.sauronsoftware</groupId>
<artifactId>jave</artifactId>
<version>1.0.2</version>
<scope>system</scope>
<systemPath>${project.basedir}/src/main/resources/lib/jave-1.0.2.jar</systemPath>
</dependency>
<!-- https://mvnrepository.com/artifact/commons-codec/commons-codec -->
<dependency>
<groupId>commons-codec</groupId>
<artifactId>commons-codec</artifactId>
<version>1.10</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient -->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.1</version>
</dependency>
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
${project.basedir}/src/main/resources/lib/jave-1.0.2.jar为项目中jar的路径
<dependency>
<groupId>it.sauronsoftware</groupId>
<artifactId>jave</artifactId>
<version>1.0.2</version>
<scope>system</scope>
<systemPath>${project.basedir}/src/main/resources/lib/jave-1.0.2.jar</systemPath>
</dependency>
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
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<includeSystemScope>true</includeSystemScope>
</configuration>
</plugin>
</plugins>
</build>
