Tika Flv File Extraction Example

In the following example, we are extracting content and metadata from .flv file. See the example.

  package tikaexample;  import java.io.File;  import java.io.FileInputStream;  import java.io.IOException;  import java.io.InputStream;  import org.apache.tika.exception.TikaException;  import org.apache.tika.metadata.Metadata;  import org.apache.tika.parser.ParseContext;  import org.apache.tika.parser.video.FLVParser;  import org.apache.tika.sax.BodyContentHandler;  import org.xml.sax.SAXException;  public class FlvExample {  public static void main(String[] args) throws IOException, SAXException, TikaException {   BodyContentHandler handler   = new BodyContentHandler();   FLVParser parser         = new FLVParser(); // It is used to extract .flv file.   Metadata metadata            = new Metadata();   ParseContext pcontext        = new ParseContext();   try (InputStream stream = new FileInputStream(new File(“newsong.flv”))) {          parser.parse(stream, handler, metadata, pcontext);       System.out.println(“Document Content:” + handler.toString());       System.out.println(“Document Metadata:”);       String[] metadatas = metadata.names();        for(String data : metadatas) {           System.out.println(data + “:   ” + metadata.get(data));         }   }catch(Exception e) {System.out.println(“Exception message: “+ e.getMessage());}     }  }  

Output:

Document Content:  Document Metadata:  hasVideo:   true  hasAudio:   true  framerate:   24.0  audiodatarate:   51.421875  audiocodecid:   2.0  videodatarate:   781.25  audiosamplesize:   16.0  audiosamplerate:   22050.0  filesize:   90580.0  duration:   1.167  videocodecid:   2.0  stereo:   false  width:   170.0  Content-Type:   video/x-flv  height:   120.0
