TIKA提取mp4文件

下面給出的程序是用來從mp4文件提取內容和元數據：

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)); } } }

保存上述代碼保存爲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：

執行上述程序後，得到如下的輸出

輸出:
