Android : Video creation using JAVACV

hi i really need help in this issue, i'm extracting video frames and with the extracted frames i'm trying to create a video using JAVACV and run it on android version 4.2.1 it create the video but can't play it, when i try a drawable images and convert it to bitmaps it works and play the video , but when i use the extracted frames it doesn't work.

HERE IS MY CODE:

/* this method is responsible for retrieve all the video Frames it's parameters the path of the video and it's duration  */
    public static void getVideoFrame(String FD, long duration) throws Exception {
         FrameRecorder recorder = new FFmpegFrameRecorder("storage/sdcard0/DCIM/video5.mp4", 640, 480);
         recorder.setVideoBitrate(1);
         recorder.setVideoCodec(AV_CODEC_ID_MPEG4);
         recorder.setPixelFormat(AV_PIX_FMT_YUV420P);
         recorder.setFrameRate(2);
         recorder.start();

        MediaMetadataRetriever retriever = new MediaMetadataRetriever();
        try {

            retriever.setDataSource(FD); // set video source

            /* for loop on video duartion in each time w increment(duration/#of frames we should get)*/
            for (int i = 0; i <= duration; i += ((duration-1) /100)) 
            {


                Bitmap b = retriever.getFrameAtTime(i*1000,retriever.OPTION_CLOSEST); // retrieve a bitmap in (i*1000) position
//               Bitmap converted=convert(b,Config.ARGB_8888);

                // convert each bitmap to ARGB_8888 configuration
                Bitmap maskBitmap = Bitmap.createBitmap( b.getWidth(), b.getHeight(), Bitmap.Config.ARGB_8888 );
                Canvas c = new Canvas();
                c.setBitmap(maskBitmap);
                Paint p = new Paint();
                c.drawBitmap(b,0,0,p);
                b.recycle();


                 IplImage imagei = IplImage.create(maskBitmap.getWidth(),maskBitmap.getHeight(),IPL_DEPTH_8U, 4);
                   Config s= maskBitmap.getConfig();
                   Log.d("configgggggggggg", s.toString());
                   maskBitmap.copyPixelsToBuffer(imagei.getByteBuffer());
                   images.add(imagei);
                   Frames.add(b);
                  // image.setImageBitmap(Frames.get(5));

            }


              for (int i = 0; i <images.size(); i++) {
                     // cvSetZero(imagei);
                     // cvPutText(imagei, "#" + i, cvPoint(320, 240), font, CvScalar.WHITE);
                      recorder.record(images.get(i));
                  }
                  recorder.stop();
        } catch (IllegalArgumentException ex) {
            ex.printStackTrace();
            System.out.println("IllegalArgumentException: " + ex.toString());

        } catch (RuntimeException ex) {
            System.out.println("RunTimeException: " + ex.toString());
            ex.printStackTrace();
        } finally {
            try {
                retriever.release();
            } catch (RuntimeException ex) {
            }
        }
