Advertisements


Given below is the program to extract content and metadata from mp3 files:

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import org.apache.tika.exception.TikaException;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.parser.mp3.LyricsHandler;
import org.apache.tika.parser.mp3.Mp3Parser;
import org.apache.tika.sax.BodyContentHandler;

import org.xml.sax.SAXException;

public class Mp3Parse {

   public static void main(final String[] args) throws Exception, IOException, SAXException, TikaException {

      //detecting the file type
      BodyContentHandler handler = new BodyContentHandler();
      Metadata metadata = new Metadata();
      FileInputStream inputstream = new FileInputStream(new File("example.mp3"));
      ParseContext pcontext = new ParseContext();
      
      //Mp3 parser
      Mp3Parser  Mp3Parser = new  Mp3Parser();
      Mp3Parser.parse(inputstream, handler, metadata, pcontext);
      LyricsHandler lyrics = new LyricsHandler(inputstream,handler);
      
      while(lyrics.hasLyrics()) {
    	  System.out.println(lyrics.toString());
      }
      
      System.out.println("Contents of the document:" + handler.toString());
      System.out.println("Metadata of the document:");
      String[] metadataNames = metadata.names();

      for(String name : metadataNames) {		        
    	  System.out.println(name + ": " + metadata.get(name));
      }
   }
}

Save the above code as JpegParse.java, and compile it from the command prompt by using the following commands:

javac Mp3Parse.java
java Mp3Parse 

Here we are passing an example.mp3 file having the following properties:
