Getting Segmentation Fault 11 about rt-motion-detection-opencv-python HOT 8 CLOSED

@hneiraf Hi, could you please provide me with the video source which gives you a segfault?
BTW, we only tested in Linux.

from rt-motion-detection-opencv-python.

@hneiraf also, try running with group_boxes=False. Do things change?

I'm still getting the same error.
I'm working with python 3.7.7 and last version of all required libraries, something related to this?

Best,

Hugo

This is what I'm getting:

Same here, seg fault on macOS.

from rt-motion-detection-opencv-python.

@SylvainGarrigues, @hneiraf I don't have MacOS to test and fix it. Please do it with your own environments and send a PR here.

I'm also getting the seg fault (also on macOS), I've been able to narrow it down to the Py_BuildValue call in the below line in scanner.c. Haven't been able to solve it, but seems like on my machine Py_BuildValue with ints always segfaults, though floats sometimes work... dunno, not familiar with this kind of python/c interoperability.

PyList_Append(boxes, Py_BuildValue("(iiii)", c_min, r_min, c_max, r_max));
