Using Opencv_videostab

Hey guys , First thanks for this Amazing library, Great work , It helped me a lot. I am stuck at this problem though. I am facing difficulties in writing this code of C into Java.

    StabilizerBase *stabilizer = 0;
    string inputPath = "";
    if (inputPath.empty())
        throw runtime_error("specify video file path");
    Ptr<VideoFileSource> source = makePtr<VideoFileSource>(inputPath);
    cout << "frame count (rough): " << source->count() << endl;
    outputFps = source->fps();
   // prepare motion estimation builders
    Ptr<IMotionEstimatorBuilder> motionEstBuilder;
    motionEstBuilder.reset(new MotionEstimatorRansacL2Builder(false));
    Ptr<IMotionEstimatorBuilder> wsMotionEstBuilder;
     wsMotionEstBuilder.reset(new MotionEstimatorRansacL2Builder(false, "ws-"));
    TwoPassStabilizer *twoPassStabilizer = new TwoPassStabilizer();
    stabilizer = twoPassStabilizer;
    twoPassStabilizer->setEstimateTrimRatio(true);
    twoPassStabilizer->setMotionStabilizer(makePtr<GaussianMotionFilter>(15));
    stabilizer->setFrameSource(source);
    stabilizer->setMotionEstimator(motionEstBuilder->build());
    stabilizedFrames.reset(dynamic_cast<IFrameSource*>(stabilizer));
    MotionModel model = stabilizer->motionEstimator()->motionModel();
    stabilizer->setRadius(15);
    stabilizer->setTrimRatio(0.1);
    stabilizer->setCorrectionForInclusion(false);
    stabilizer->setBorderMode(BORDER_REPLICATE);
    InpaintingPipeline *inpainters = new InpaintingPipeline();
    Ptr<InpainterBase> inpainters_(inpainters);

    outputPath = "";

      __android_log_write(ANDROID_LOG_ERROR, "Tag", "Output path set ");

    quietMode = 0;

Can anyone Help ?
