TIKA提取mp4文件

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 typeBodyContentHandler handler = new BodyContentHandler();Metadata metadata = new Metadata();FileInputStream inputstream = new FileInputStream(new File("example.mp4"));ParseContext pcontext = new ParseContext();//Html parserMP4Parser 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：

执行上述程序后，得到如下的输出

输出:
