Android : Create mpeg4 movie file using jcodec for Android

I tried write mpeg4 movie file using jcodec 0.1.7 / Android 4.4.2 from PNG files.

But, the written file is broken (Can not open using Android, VLC Player etc.)

How to method to write mpeg4 correctly?

            File destFile = new File(destPath);
            try {
                SequenceEncoder sequenceEncoder = new SequenceEncoder(destFile);

                String baseDir = cacheDirectoryPath();
                File dirF = new File(imgDir);
                File files[] = dirF.listFiles();

                for (int i = 0; i < 200; i++) {
                    Log.d("File: ", files[i].getAbsolutePath());
                    Bitmap bmp1 = BitmapFactory.decodeFile(files[i].getAbsolutePath());
                    Picture pic = BitmapUtil.fromBitmap(bmp1);
                    sequenceEncoder.encodeNativeFrame(pic);
                }

                sequenceEncoder.finish();

            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
