I'm trying to convert an image from YUV to RGB inside onImageAvailable method in java.
I'm using openCV for conversion. I can't use RGB format from android Camera2 for avoiding frame loss.
I can't chose the best format for conversion.
Image.Plane Y = image.getPlanes()[0];
Image.Plane U = image.getPlanes()[1];
Image.Plane V = image.getPlanes()[2];
Y.getBuffer().position(0);
U.getBuffer().position(0);
V.getBuffer().position(0);
int Yb = Y.getBuffer().remaining();
int Ub = U.getBuffer().remaining();
int Vb = V.getBuffer().remaining();
ByteBuffer buffer = ByteBuffer.allocateDirect( Yb + Ub + Vb);
buffer.put(Y.getBuffer());
buffer.put(U.getBuffer());
buffer.put(V.getBuffer());
// Image is 640 x 480
Mat yuvMat = new Mat(960, 640, CvType.CV_8UC1);
yuvMat.put(0, 0, buffer.array());
// I don't know what is the correct format
Mat rgbMat = new Mat(yuvMat.rows, yuvMat.cols, CvType.CV_8UC4);
Imgproc.cvtColor(yuvMat, rgbMat, Imgproc.COLOR_YUV420sp2RGBA);
final Bitmap bit = Bitmap.createBitmap(rgbMat.cols(), rgbMat.rows(), Bitmap.Config.ARGB_8888);
Utils.matToBitmap(rgbMat, bit);
Actually I can obtain only cropped grayscale image
