hello
I'm not good very in english
I want open a "10 bit YCbCr 4:2:2 frame" and show it in openCV
frame size is: 720 * 576
my source code :
void main (int argc, char ** argv)
{
streampos size;
char *pData;
ifstream file("C:\\639.bin", ios::in | ios::binary | ios::ate);
Mat YUV(576, 720, CV_8UC3);
Mat RGB(576,720, CV_8UC3);
if (file.is_open())
{
size = file.tellg();
pData = new char[size];
file.seekg(0, ios::beg);
file.read(pData, size);
file.close();
long k = 0;
int n = 0;
int Y, Cb, Cr;
for (int i = 0; i < 576; i++)
{
n = 0;
for (int j = 0; j < 1920; j += 16)
{
k = i * 1920 + j;
Y=YUV.at>(Point(n, i))[0] = ((pData[k+1]&252)/4.0 + (pData[k + 2] & 15) * 64)/4.0;

}
cvtColor(YUV, RGB, CV_YUV2RGB);
imwrite("C:\\1.jpg", RGB);
namedWindow("1");
imshow("1", RGB);
waitKey(0);
}
}
after run source code following image is shown:
but orginal frame is:
this frame captured from Intensity DeckLink Black MagicDesign Capture Card and Pixel Format is:
please help for solve this problem
thanks
