Linux/AM5728: OpenCV DSP build error

The software team have been notified. They will respond here.

Hello,

Can you please share the full build logs? If you could provide steps to reproduce this on our end that would be good too.

#include <unistd.h>
#include <time.h>
#include <stdio.h>
#include <opencv2/opencv.hpp>
#include <opencv2/core/ocl.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

#ifndef _OCL_HPP_
#include "opencv2/core/ocl.hpp"
#endif

using namespace cv;
using namespace std;


int main(){
VideoCapture cap;
cap.open("1.avi");

if(!cap.isOpened())
{
cout << "colud not load vodeo...."<<endl;
return -1;
}

ocl::setUseOpenCL(true);
Mat matSrc;
while(cap.read(matSrc))
{
cvtColor( matSrc , matSrc , CV_RGB2GRAY );

Mat padded;
int m = getOptimalDFTSize(matSrc.rows); // Return size of 2^x that suite for FFT
int n = getOptimalDFTSize(matSrc.cols);
// Padding 0, result is @padded
copyMakeBorder(matSrc, padded, 0, m-matSrc.rows, 0, n-matSrc.cols, BORDER_CONSTANT, Scalar::all(0));

// Create planes to storage REAL part and IMAGE part, IMAGE part init are 0
Mat planes[] = {Mat_<float>(padded), Mat::zeros(padded.size(), CV_32F) };

UMat complexI;
merge(planes, 2, complexI);
cv::dft(complexI, complexI);
}
ocl::setUseOpenCL(false);

return 0;
}




We tried to use DSP accelerated cv::dft()

It would compiled the opencl kernel for about 5 mins and return a compile error :

>>> Optimizer terminated abnormally
>>>> in function ifft_multi_radix_rows()

>> Compilation failure
OpenCL program build log: -D LOCAL_SIZE=50 -D kercn=10 -D FT=float -D CT=float2 -D RADIX_PROCESS='fft_radix2_B5(smem,twiddles+0,ind,1,25);fft_radix5_B2(smem,twiddles+1,ind,2,1T

>> Compilation failure

It will succeed in ARM .My SDK is 4.2.

Please help us ,we need dsp to accelerate dft();

Hi,
We focus on this issue for a long time with no progress.
Do you get any sugestions or updates we can reference ?
