Android中的Instagram等视频和图像过滤器

我正在开发一个应用程序，它需要像Instagram这样的视频和图像过滤器。我在互联网上花了很多时间。我没有发现任何东西非常有用。现在我正在使用这段代码进行图像过滤器，但响应时间非常慢

public class LightingFilterPagerAdapter extends PagerAdapter {
public static String[] styles = { "No Filter", "Chrome", "Cool", "Classic", "Fade", "Noir", "Greyscale", "Highlight", "Invert", "Snow", "MeanRemova", "SepiaToning" };
private Bitmap originBitmap, filteredBitmap;
private SparseArray<View> selectorArray = new SparseArray<View>();

private LayoutInflater layoutInflater;

public LightingFilterPagerAdapter(Context context) {
    layoutInflater = LayoutInflater.from(context);
}

public void setFilterable(Bitmap bitmap) {
    this.originBitmap = null == bitmap ? BitmapFactory.decodeResource(layoutInflater.getContext().getResources(), R.drawable.ic_launcher) : Bitmap.createScaledBitmap(bitmap,
            150, 150, false);
}

@Override
public float getPageWidth(int position) {
    return 0.35f;
}

public Object instantiateItem(View container, final int position) {
    View view = layoutInflater.inflate(R.layout.filter_pager_item, null);

    if (position == 0 || position > styles.length) {
        filteredBitmap = originBitmap;
    } else {
        filteredBitmap = applyStyle(position, originBitmap);
    }

    // initially selected no filter
    View selView = view.findViewById(R.id.selector_v);
    selectorArray.put(position, selView);
    selView.setVisibility(0 == position ? View.VISIBLE : View.GONE);

    ImageView filterIv = (ImageView) view.findViewById(R.id.filter_iv);
    filterIv.setImageBitmap(filteredBitmap);

    TextView filterTv = (TextView) view.findViewById(R.id.filter_tv);
    filterTv.setText(styles[position]);

    view.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // unselect all except selected one
            for (int i = 0; i < selectorArray.size(); i++) {
                View selectorView = selectorArray.get(selectorArray.keyAt(i));
                selectorView.setVisibility(i == position ? View.VISIBLE : View.GONE);
            }

            if (null != filterSelectedListener) {
                filterSelectedListener.onFilterSelected(position, styles[position]);
            }
        }
    });

    ((ViewPager) container).addView(view);

    return view;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    ((ViewPager) container).removeView((View) object);
}

@Override
public int getCount() {
    return null == styles ? 0 : styles.length;
}

@Override
public boolean isViewFromObject(View arg0, Object arg1) {
    return arg0 == ((View) arg1);
}

private FilterSelectedListener filterSelectedListener;

public void setFilterSelectedListener(FilterSelectedListener listener) {
    this.filterSelectedListener = listener;

对于图像过滤器，我发现非常使用完整库，但是对于视频过滤器，我仍然在寻找视频过滤器，我遵循了视频预览上实现的过滤器。但是仍然在寻找解决方案，将过滤器添加到视频并保存它
