Question

The problem is the following:

There is a CIF video file that is supposed to be processed by the OpenCV.
Unfortunately, I am not able to read frames from this video. The following code

cv::VideoCapture cap = cv::VideoCapture("foreman.cif");
if(!cap.isOpened()) {
    std::cout << "Open file error" << std::endl;
    return -1;
}

gives Open file error in console.

Is there any way to grab frames from CIF video using OpenCV?

I don’t think openCV can read raw YUV streams directly.
You can use memcoder to convert it to an avi, compressed or not.
Or you can use regular c/c++ to read the data blocks, copy them into an image and use cvCvtColor() to convert YUV->BGR
