Capture Frames or Thumbnails of Video Files using Xuggler Library in JAVA

In this Tutorial, i am going to describe , How to capture Frame or Thumbnails of Video Files using Xuggler library.For using Xuggler you need to download the library version greater than  5.2 i.e. xuggle-xuggler-5.3.jar or latest version, because  earlier version has a large amount of native code that needs to be specifically compiled for different operating systems.
So you can download the Xuggler library form here:
1. http://xuggle.googlecode.com/svn/trunk/repo/share/java/xuggle/xuggle-xuggler/
                                                                 OR
2. Download from here




 Here is the code:

package com.jkit;
package com.jkit;

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;

import com.xuggle.mediatool.IMediaReader;
import com.xuggle.mediatool.MediaListenerAdapter;
import com.xuggle.mediatool.ToolFactory;
import com.xuggle.mediatool.event.IVideoPictureEvent;
import com.xuggle.xuggler.Global;

public class ThumbnailCreation {

 
   public static final double SECONDS_BETWEEN_FRAMES = 15;
      private static final String inputFilename = "D:/loginInterceptor.mp4";
      private static final String outputFilePrefix = "D:/snapshots/mysnapshot";
      // The video stream index, used to ensure we display frames from one and
      // only one video stream from the media container.
      private static int mVideoStreamIndex = -1;
      // Time of last frame write
      private static long mLastPtsWrite = Global.NO_PTS;
      public static final long MICRO_SECONDS_BETWEEN_FRAMES =
              (long) (Global.DEFAULT_PTS_PER_SECOND * SECONDS_BETWEEN_FRAMES);

      public static void main(String[] args) {
          IMediaReader mediaReader = ToolFactory.makeReader(inputFilename);

          // we want BufferedImages created in BGR 24bit color space
          mediaReader.setBufferedImageTypeToGenerate(BufferedImage.TYPE_3BYTE_BGR);

          mediaReader.addListener(new ImageSnapListener());

          // read out the contents of the media file and
          // dispatch events to the attached listener
          while (mediaReader.readPacket() == null);

      }

      private static class ImageSnapListener extends MediaListenerAdapter {

          public void onVideoPicture(IVideoPictureEvent event) {

              if (event.getStreamIndex() != mVideoStreamIndex) {
                  // if the selected video stream id is not yet set, go ahead an
                  // select this lucky video stream
                  if (mVideoStreamIndex == -1) {
                      mVideoStreamIndex = event.getStreamIndex();
                  } // no need to show frames from this video stream
                  else {
                      return;
                  }
              }

              // if uninitialized, back date mLastPtsWrite to get the very first frame
              if (mLastPtsWrite == Global.NO_PTS) {
                  mLastPtsWrite = event.getTimeStamp() - MICRO_SECONDS_BETWEEN_FRAMES;
              }

              // if it's time to write the next frame
              if (event.getTimeStamp() - mLastPtsWrite
                      >= MICRO_SECONDS_BETWEEN_FRAMES) {

                  String outputFilename = dumpImageToFile(event.getImage());

                  // indicate file written
                  double seconds = ((double) event.getTimeStamp())
                          / Global.DEFAULT_PTS_PER_SECOND;
                  System.out.printf(
                          "at elapsed time of %6.3f seconds wrote: %s\n",
                          seconds, outputFilename);

                  // update last write time
                  mLastPtsWrite += MICRO_SECONDS_BETWEEN_FRAMES;
              }

          }

          private String dumpImageToFile(BufferedImage image) {
              try {
                  String outputFilename = outputFilePrefix
                          + System.currentTimeMillis() + ".png";
                  ImageIO.write(image, "png", new File(outputFilename));
                  return outputFilename;
              } catch (IOException e) {
                  e.printStackTrace();
                  return null;
              }
          }
      }
 }
Now run the application, you will see the Console output like this:
