Hi, I followed your cheat sheet 1(also your video) closely,however, when I heat F5 to start debugging, the error pop out telling me the CannyStill1.exe program cannot start, Operation not supported, unknown error: 0x800700d8.

Is it because I am using a 32-bit Windows 10 OS?

Hi,
I am downloading opencv for python 2.7.5 for the first time, and I followed all the steps on the installation tutorial but to no avail. I've tried uninstalling and reinstalling a couple of times but nothing I do seems to work. I've attached a screenshot of the error I am getting; if anyone could tell me how to fix it, I'd super appreciate it. Thanks

I can't see the video from USA.

Hello ,

I have managed to follow your instruction and successfully ran your sample file to process an image using opencv. Then I started to create a tiny application of my own and needed to use the debugger. Since I am in Windows , I had to setup the Windows debugger separately by visual studio installer. After the installation of the Windows SDK, I pointed to the windows debugger from the QtCreator and I started to get compilation error with the same sample application that used to work after the initial setup. The error is:

"C:\Users\si3699\Documents\CustomInstallation\ComputerVision\opencv\build\include\opencv2\core\types_c.h:55: error: C1083: Cannot open include file: 'assert.h': No such file or directory"

Some hint is requested to get around this issue.

Thanks

Hey,

Thanks

Previously I follow your turtorial, but when I uses the following code, I found the error and every time this is talking about "opencv_ffmpeg300.dll". I can't get rid form this error.
I am waiting for your response.

include<opencv2/core/core.hpp>

include<opencv2/highgui/highgui.hpp>

include<opencv2/imgproc/imgproc.hpp>

int main ( int argc, char** argv)
{
cvNamedWindow( "Example2", CV_WINDOW_AUTOSIZE);
CvCapture* capture = cvCreateFileCapture( argv[1] );
IplImage* frame;
while(1)
{
frame = cvQueryFrame( capture );
if( !frame ) break;
cvShowImage( "Example2", frame );
char c = cvWaitKey(33);
if( c == 27) break;
}
cvReleaseCapture( &capture );
cvDestroyWindow( "Example2" );
}
