I have open cv 3.2.0 in python 2.7.13 on windows 10. Eventually I would like to run a background substractor, but I`m stuck in the very first step. I am not being able to make make to show a frame from a video in a file. Here is the code I have tried to far
import cv2
cam = cv2.VideoCapture("C:\\Users\\Public\\Videos\\Sample Videos\\wildlife.avi")
worked,f = cam.read()
cv2.imshow('f',f)
k=cv2.waitKey(1)
cv2.imshow() gives the following error:
"error: (-215) size.width>0 && size.height>0 in function cv::imshow"
worked is always returning FALSE, which according to what I could google it implies cam.read() is not reading the frame correctly
I google for solutions but so far none worked. Tried to use , different movies, formats (mp4,avi,wmv), internal codecs (h264, msmpeg4v2). I saw some suggestion of recompiling the library to better interact with 3rd party codecs, but I got opencv from the website, and numpy and matplotlib through pip. It seems drastic to redo it.
Does anyone knows what might be going on?
