OpenCV SIGSEGVС++ minGW

Question

请帮忙。即使是在简单的程序中也有内存和异常的错误。调试中的代码块+ mingw - SIGSEGV，调用堆栈 - user32.dll。运行时崩溃与0xc0000005错误。 VC也因未处理的异常而崩溃。

using namespace cv; 
using namespace std; 

int main(int argc, char* argv[]) 
{ 
    CvCapture* capture = cvCreateCameraCapture(CV_CAP_ANY); //cvCaptureFromCAM(0); 
    assert(capture); 

    IplImage* frame=0; 

    cvNamedWindow("capture", CV_WINDOW_AUTOSIZE); 

    int counter=0; 
    char filename[512]; 

    while(true){ 

      frame = cvQueryFrame(capture); 


      cvShowImage("capture", frame); 

      char c = cvWaitKey(33); 
      if (c == 27) { 
        break; 
      } 

    } 

    cvReleaseCapture(&capture); 
    cvDestroyWindow("capture"); 
    return 0; 
    } 

Answer 1

您是否尝试过交换那些下面几行：

cvDestroyWindow("capture"); 

和

cvReleaseCapture(&capture); 

我相信之前你应该叫cvDestroyWindow比cvReleaseCapture。我认为窗户成了capture的拥有者，应该首先销毁。
