oops, sorry, I wrote the wrong things (it's getting late : )
i'm actually erring on this
######### typdef ############
cdef class CvCapture:
cdef c_highgui.CvCapture* thisptr
# convienience functions
def queryFrame(self):
# get and return an IplImage from from a capture source
# equivalent to img = cvQueryFrame(CvCapture* capture)
# make sure to set capture width and height before calling this
cdef c_cxcore.IplImage* img
cdef IplImage pyimg = IplImage()
img = c_highgui.cvQueryFrame(self.thisptr)
pyimg.thisptr = img
return pyimg
def __dealloc__(self):
c_highgui.cvReleaseCapture(&self.thisptr)
def cvCreateCameraCapture(device):
cdef c_highgui.CvCapture* cap = c_highgui.cvCreateCameraCapture(device)
cdef CvCapture pycap = CvCapture()
pycap.thisptr = cap
return pycap
####################
python code
cam = cvCreateCameraCapture(0)
img = cam.queryFrame()
img.show() <----- this works fine
img = cam.queryFrame() <---------- I crash here
sorry for the confusion
Chris
