glsurfaceview

I am using this code to give multiple effect on bitmap that is on GlSurfaceView. apply-effects-on-image-using-effects Now, I want to save the bitmap. They have given the code to save the bitmap but with that, whole GlSurfaceView is going to be saved as bitmap image. Instead I want to save only bitmap area to save as Image. There is method that takes pixels and make bitmap from that and also make image. e.g.: public Bitmap takeScreenshot(GL10 mGL) { final int mWidth = mEffectView.getWidth(); final int mHeight = mEffectView.getHeight(); IntBuffer ib = IntBuffer.allocate(mWidth * mHeight);

I'm making a virtual reality application where the camera should detect faces, locate them and show their location on the camera preview. I know of 3 ways to do it, I'd like to use GLSurfaceView to be as fast as possible ( according to this post ), but currently I'm trying to draw on the same SurfaceView where the camera is using for its preview. My callback to draw on it would be onFaceDetection like so: public class MyActivity extends Activity implements SurfaceHolder.Callback, Camera.FaceDetectionListener { Camera camera; SurfaceView svPreview; SurfaceHolder previewHolder; TextView tvInfo;

I am new to the world of Open Gl and I have googled a lot but i am unable to find a way to implement Effects on a video being played. After some research i have finally found a class that can be used to play video on a GLSurfaceView. And i know from Google documentation and that we can apply effects on a video. By following this post i was able to successfully apply effects on bitmaps. Now i want to do that for my video so any help or pointers is appreciated. Here is the VideoSurfaceView that i am using to Render Video that is being played package me.crossle.demo.surfacetexture; import java.io
