opencv 2.1.0 memory leaks

[gonzalo.llorente@…]

Hi,

I think there must be something wrong with function cvShowImage(). A simple piece of code that plays a video like (see below) just keeps allocating memory all the time. This same program compiled against port opencv 2.0.0 just takes 30 MB and stays around that amount of memory.

code:

#include <stdio.h> #include "highgui.h"

int main(int argc, char* argv[]) {

if (argc != 2) {

printf("%s <file>\n", argv[0]); return -1;

}

char *title = argv[1];

cvNamedWindow(title, CV_WINDOW_AUTOSIZE); CvCapture *capture = cvCreateFileCapture(argv[1]); IplImage *frame;

while (1) {

frame = cvQueryFrame(capture); if (!frame)

break;

cvShowImage() posible memory leak... cvShowImage(title, frame); char c = cvWaitKey(33); if (c == 27)

break;

}

cvReleaseCapture(&capture); cvDestroyWindow(title); return 0;

}

If I comment out the line that show the image on screen (cvShowImage()) the behaviour of the memory is right. So I think that maybe something is wrong with this function...

I don't know if this should be reported to the opencv developers... Thanks for the help.

Hi,

This issue has been reported months ago. Someone pointed out a fix ticket in the opencv list.

​https://code.ros.org/trac/opencv/changeset/3253

is this patch applied in latest opencv macport?
