Play video from recorded file in java

Hello everybody,

using Java (Eclipse) and a recorded video file *.rssdk, how can I simply show the video? 

Currently I tried this according to the documentation examples:

 

import java.awt.Color;

import java.awt.Graphics;
import java.awt.Image;
import java.awt.Point;

import javax.swing.JFrame;
import javax.swing.JPanel;

import intel.rssdk.PXCMCapture;
import intel.rssdk.PXCMImage.Access;
import intel.rssdk.PXCMImage.ImageData;
import intel.rssdk.PXCMSenseManager;
import intel.rssdk.pxcmStatus;

public class MainClass {

    public static int nframes = 1000000;

    public static void main(String s[]) {

        String filename = "C:\\1_RealSense\\Videos\\rec2.rssdk";

        // Create a SenseManager instance
        PXCMSenseManager sm = PXCMSenseManager.CreateInstance();

        // Set file playback name
        sm.QueryCaptureManager().SetFileName(filename, false);

        // Enable stream and Initialize
        sm.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_COLOR, 0, 0);
        sm.Init();

        // Set realtime=true and pause=false
        sm.QueryCaptureManager().SetRealtime(false);
        sm.QueryCaptureManager().SetPause(true);

        JFrame window = new JFrame("Haupttitel");
        window.setSize(1000, 800);
        window.setBackground(Color.white);
        window.setLocationRelativeTo(null);
        
        JPanel videoPanel = new JPanel();
        videoPanel.setSize(640, 480);
        videoPanel.setBackground(Color.black);
        videoPanel.setLocation(new Point(10,10));
        window.add(videoPanel);
        
//        window.pack();
        window.setVisible(true);


        // Streaming loop  
        for (int i = 0; i < nframes; i+=3) {  
          
           // Set to work on every 3rd frame of data  
           sm.QueryCaptureManager().SetFrameByIndex(i);  
           sm.FlushFrame();  
          
           // Ready for the frame to be ready  
           pxcmStatus sts = sm.AcquireFrame(true);  
           if (sts.compareTo( pxcmStatus.PXCM_STATUS_NO_ERROR)>0) break;  
          
           // Retrieve the sample and work on it. The image is in sample->color.  
           PXCMCapture.Sample sample = sm.QuerySample();  
         
          
          Graphics g = videoPanel.getGraphics();
          ImageData id = new ImageData();
          sample.rgb.AcquireAccess(Access.ACCESS_READ, id);
          
          Image img=null;
          
          g.drawImage(img, 0, 0, null);
           
           // Resume processing the next frame  
           sm.ReleaseFrame();  
        }  
          
        // Clean up  
        sm.FlushFrame();  

    }

}

 

I try to get each 3. frame from the rgb images (in the docs it says color, but that does not work, so I took rgb instead) and draw it on the JPanel. So far, this doesnt work. Can you help me in any way? Is it even possible to convert from PXCMImage to java.awt.image ?

 

The debugger also says that the sample.depth / ir / left / right are null. Only sample.rgb shows a PXCMImage

 

best regards,

J.
