Hi,
I just want to save a picture from my webcam with OpenCv and Python on my Ubuntu 10.
OpenCv can connect with the webcam.
But I get this error:
OpenCV Error: Null pointer (NULL array pointer is passed) in cvGetMat, file /build/buildd/opencv-2.1.0/src/cxcore/cxarray.cpp, line 2376
Traceback (most recent call last):
File "video.py", line 5, in <module>
cv.SaveImage("test.JPG", img)
cv.error: NULL array pointer is passed
