I almost tested all possible combinations!

I did the same thing. my specified argument is like : C:\Users\ASUS\my_proj\video.avi But still not working. actually it was working well with OpenCV 2.4.1

Thanks for suggestion. I did the way you said but I get error on " argv[1].c_str() " . I added the line to my project for multibyte char DEFINES += _MBCS

Hi, I want to create a track bar in OpenCV 2.4.3. I write a sample code for that as regular, but the output is not like before.

This is my sample code and I'm using QT creator 5 on windows platform.

 int aa=5;
 cv::namedWindow("Cut histogram edges input image",1);
 cv::createTrackbar("histogram edges clipping limit", "Cut histogram edges input image",&aa,50);
 cv::namedWindow("Retina Parvo", 1);

Does anybody know why my output window is like the image above? Thanks

Hi everybody, Recently I migrated to OpenCV 2.4.3 from 2.4.1.

My program which worked well with 2.4.1 version now encounters problem with 2.4.3.

The problem is related to VideoCapture that can not open my video file.

I saw similar problem while searching the net but I couldn't find a proper solution for this. Here is my sample code:

VideoCapture video(argv[1]);
while(video.grab())
{
    video.retrieve(imgFrame);
    imshow("Video",ImgFrame);
    waitKey(1);
}

It's worth mentioning that capturing video from webcam device works well but I want to grab stream from file.

I'm using Qt creator 5 and I compiled OpenCV with MingW. I'm on Windows platform either.

I tried several different video formats and I rebuilt opencv with and without ffmpeg. But the problem is still consistent.

Any idea to solve the problem?

Thanks
