OpenCV错误：cvGetSize中的参数错误（数组应为CvMat或IplImage）

Question

I have successfully written a video processing program. I used ubuntu and Netbeans for programming. When I run this program on netbeans it runs perfectly and gives expected output.

I built executable file of this program both in debug and release mode and tried to run them in the command line. Now I get the following error. But Netbeans doesn't complain about this. Could someone point out what might be the problem?

OpenCV Error: Bad argument (Array should be CvMat or IplImage) in cvGetSize, file /home/<user>/trunk/opencv/modules/core/src/array.cpp, line 1238
terminate called after throwing an instance of 'cv::Exception'
  what():  /home/<user>/trunk/opencv/modules/core/src/array.cpp:1238: error: (-5) Array should be CvMat or IplImage in function cvGetSize

thank you in advance

Answer 1

Can you check if the input argument to cvGetSize is:

1. a NULL pointer? What is the result of querying/retrieving the frame?
2. a CvSeq?
3. a 1- or 3-dimensional array?

Usually it is the first.

That's the way OpenCV talks to you - it's more often the runtime exception than a compiler error.
