下面给出的程序是用来从mp4文件提取内容和元数据：

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));
          }
       }  
    }

保存上述代码保存为JpegParse.java，并通过使用下面的命令从命令提示编译：

javac Mp4Parse.java
    java Mp4Parse

下面给出的是example.mp4的快照属性：

![Passing MP4][]

执行上述程序后，得到如下的输出

输出:

Contents of the document:
    
    Metadata of the document:
