Advertisements


Given below is the program to extract content and metadata from mp4 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.mp4.MP4Parser;
import org.apache.tika.sax.BodyContentHandler;

import org.xml.sax.SAXException;

public class Mp4Parse {

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

      //detecting the file type
      BodyContentHandler handler = new BodyContentHandler();
      Metadata metadata = new Metadata();
      FileInputStream inputstream = new FileInputStream(new File("example.mp4"));
      ParseContext pcontext = new ParseContext();
      
      //Html parser
      MP4Parser MP4Parser = new MP4Parser();
      MP4Parser.parse(inputstream, handler, metadata,pcontext);
      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 Mp4Parse.java
java Mp4Parse 

Given below is the snapshot of properties of Example.mp4 file.
