How To Get Metadata Of Video URL In Spring Boot Application

In this blog, we are going to create a simple spring boot project to extract metadata of the video URL. To extract the metadata of the video URL we are using Java 8 and Spring Boot 2.0 framework. To get the metadata of a video URL, We are using the Ws.Schild library of Java. In this library, we have many classes and services like multimedia object class, Multimedia info class, Through which we are able to get video URL metadata without downloading that video.

Step 1: Add Ws.Schild library in .pomx file :

<dependency>

<groupId>ws.schild</groupId>

<artifactId>jave-core</artifactId>

<version>3.2.0</version>

</dependency>

<dependency>

<groupId>ws.schild</groupId>

<artifactId>jave-all-deps</artifactId>

<version>3.2.0</version>

</dependency>

Step 2: Write Java code to extract metadata of a video URL :

package com.video;

import lombok.extern.slf4j.Slf4j;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import ws.schild.jave.EncoderException;

import ws.schild.jave.InputFormatException;

import ws.schild.jave.MultimediaObject;

import ws.schild.jave.info.MultimediaInfo;

import java.net.MalformedURLException;

import java.net.URL;

@SpringBootApplication

public class VideoApplication {

public static void main(String[] args) throws MalformedURLException, EncoderException {

SpringApplication.run(VideoApplication.class, args);

MultimediaInfo multimediaInfo = getInfo("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4");

long minutes = (multimediaInfo.getDuration() / 1000) / 60;

long seconds = (multimediaInfo.getDuration() / 1000) % 60;

System.out.println(multimediaInfo.getDuration() + " Milliseconds = " + minutes + " minutes and "+ seconds + " seconds.");

}

public static MultimediaInfo getInfo(String videoUrl) throws MalformedURLException, EncoderException {

URL url = new URL(videoUrl);

try {

MultimediaObject multimediaObject = new MultimediaObject(url);

MultimediaInfo multimediaInfo = multimediaObject.getInfo();

return multimediaInfo;

}catch (InputFormatException e){

e.printStackTrace();

return null;

}

}

}

Step 3: Run the video application and check the output in the console :

2021-12-25 17:26:25.534 INFO 10693 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 8094 (http) with context path ''
