TIKA提取mp4檔案

下面給出的程式是用來從mp4檔案提取內容和後設資料：

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));
      }
   }  
}

儲存上述程式碼儲存為JpegParse.java，並通過使用下面的命令從命令提示編譯：

javac Mp4Parse.java
java Mp4Parse 

下面給出的是example.mp4的快照屬性：

執行上述程式後，得到如下的輸出

輸出:
