Description

Hi there,

I'm using the new OpenCV 2.4.0, compiled with VisualStudio 2010 (Win64), CMake 2.8.8 under Windows 7. I built "debug" as well as "release" configurations and tested both with the same result:

While using the function imread() I always see a gray image (with the correct window size), no matter whether using bmp, jpg or any other stuff.

Trying to capture a single frame and then displaying it with imshow() leads to no errors.

While compiling, no errors/warnings were found. There are also no errors during runtime.

I tried both using absolute and relative path for the image, but it had no effect at all.

Any ideas?

Greetings

Florian

You have to use cv::waitKey instead of getchar.
Please, refer to waitKey documentation for the details.
