cv::imshow causes error: (-206:Bad flag (parameter or structure field)) Unrecognized or unsupported array type in function 'cvGetMat'

[Yensl2024]

Can someone provides me some guidance in solving this issue please? The error dissappeared when I comment the 'cv::imshow();' line.

This main.cpp is running ok command terminal without any error.

Hi and welcome to devnet,

While you are using Qt Creator, you should rather contact the OpenCV folks as they will have better knowledge on such matters.
