What is the minimum Visual Studio version that fully supports OpenCV 3? I have tried with Visual Studio 2008 and OpenCV 2.3.1(the last version supposed to work with 2008) but only very basic samples such as webcam display worked.

Hi, Can you tell me how to change stream from video to webCam. I change the capVideo to capVideo(0) and i comment capVideo.open("768x576.avi") but i have comunication that: "error: video file must have at least two frames". I comment this too but the program show only once image from camera and stop. Thanks for reply !!

Thanks for the informative vid! Just wanted to know how I would change the main.cpp source code if I wanted to use my webcam instead of a video file, any help would be great!

Hello I am trying to run your code in ubuntu linux and get this error message error: ISO C++ forbids declaration of 'convexHull' with no type [-fpermissive] for (auto &convexHull : convexHulls) can you help me with this? Many thanks in advance.

If you want to use the same code with a live video stream from a Webcam, just do the following steps:

capVideo.open(0); // To capture from the webcam

// Then comment all the following " IF condition "
/* if <
{ capVideo.read(imgFrame2);
}
else { std::cout << "End of Video \n" ;
break;
}
} */

Then replace taht by this instruction

capVideo.read(imgFrame2);

And it should work fine

hi, do you have a tutorial c++ to take and save date/time from a video?

[aiandcybersecurity]
