I can’t figure out why my code is not working it says something about config not being installed but I have installed almost every flipping package that has these stuff what have I done wrong in my code can anyone help me out?
Error message
My code yes this is from I cannot recall what website I got it from I have tried everything and it’s quite frustrating
import cv2
videoName = 'Test.mp4'
#create a videoCapture Object (this allow to read frames one by one)
video = cv2.VideoCapture(videoName)
#check it's ok
if video.isOpened():
print('Video Succefully opened')
else:
print('Something went wrong check if the video name and path is correct')
#define a scale lvl for visualization
scaleLevel = 3 #it means reduce the size to 2**(scaleLevel-1)
windowName = 'Video Reproducer'
cv2.namedWindow(windowName )
#let's reproduce the video
while True:
ret,frame = video.read() #read a single frame
if not ret: #this mean it could not read the frame
print("Could not read the frame")
cv2.destroyWindow(windowName)
break
reescaled_frame = frame
for i in range(scaleLevel-1):
reescaled_frame = cv2.pyrDown(reescaled_frame)
cv2.imshow(windowName, reescaled_frame )
waitKey = (cv2.waitKey(1) & 0xFF)
if waitKey == ord('q'): #if Q pressed you could do something else with other keypress
print("closing video and exiting")
cv2.destroyWindow(windowName)
video.release()
break
#release the video
video.release()
Can anyone help me?
Hi @BassetHoundDev. Thank you for your post.

Hey, @BassetHoundDev!
You could use this code :
# importing libraries
import cv2
import numpy as np
# Create a VideoCapture object and read from input file
cap = cv2.VideoCapture('Spend Your Summer Vacations\
Wisely! Ft. Sandeep Sir _ GeeksforGeeks.mp4')
# Check if camera opened successfully
if (cap.isOpened()== False):
print("Error opening video file")
# Read until video is completed
while(cap.isOpened()):
# Capture frame-by-frame
ret, frame = cap.read()
if ret == True:
# Display the resulting frame
cv2.imshow('Frame', frame)
# Press Q on keyboard to exit
if cv2.waitKey(25) & 0xFF == ord('q'):
break
# Break the loop
else:
break
# When everything done, release
# the video capture object
cap.release()
# Closes all the frames
cv2.destroyAllWindows()
Sadly,that doesn’t work here is the error message that appears
Try after running in shell:
pip install --force-reinstall opencv-python&
And make sure the process isn’t interrupted
I was gonna ask about that how do you install stuff through the shell I still cant figure it out
depends on the “stuff”. For python packages, run in shell:
poetry add <package name>
For general nix packages, search using https://search.nixos.org, then install using:
sed -i "s/\];/ pkgs.<package name>
&/" replit.nix
Im sorry i sound annoying can you send a picture of how the shell would look if you installed open cv im really getting frustrated at this if you could this would help me a ton if i can see it thanks
Wdym that link doesn’t work
Is the video for Rick Rolling
No lol i was making a Easter egg of a show but if you want me to rick roll you i can ha ha
Did you try replit package manager to install?
Yes I tried many packages and still didn’t work
I have this same problem but I’m getting this error:
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/runner/MotionTracking/venv/lib/python3.8/site-packages/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: xcb.
