@@shivanigangwar1192 Hey! So, I had a lot of errors as well! Thats how we learn actually, I scrolled through stack overflow,used chatGpt,google, a lot of other sources to finally remove all the errors,please be careful about the directory you provide for the pictures and video
,here is my code :

[@nakul--]

import cv2
import time
from datetime import datetime
import argparse
import os
face_cascade = cv2.CascadeClassifier("haarcascade_frontalface_default.xml")
video = cv2.VideoCapture(0)
counter = 0
while True:
check, frame = video.read()
if frame is not None:
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
faces = face_cascade.detectMultiScale(gray, scaleFactor=1.1, minNeighbors=10)

for x, y, w, h in faces:
img = cv2.rectangle(frame, (x, y), (x+w, y+h), (0, 255, 0), 3)
exact_time = datetime.now().strftime('%Y-%b-%d-%H-%M-%S-%f')
file_name = "C:/Users/dell/Desktop/Computer Vision/project/face_detected_{}.jpg".format(counter)
cv2.imwrite(file_name, frame, [cv2.IMWRITE_JPEG_QUALITY, 100])
print("Saved:", file_name)
counter += 1
cv2.imshow("home surv", frame)
key = cv2.waitKey(1)
if key == ord('q'):
break
video.release()
cv2.destroyAllWindows()
dir_path = "C:/Users/dell/Desktop/Computer Vision/project/"
ext = "jpg"
output = "C:/Users/dell/Desktop/Computer Vision/project/output.mp4"
images = [f for f in os.listdir(dir_path) if f.endswith(ext)]
images.sort()
if len(images) > 0:
first_image_path = os.path.join(dir_path, images[0])
frame = cv2.imread(first_image_path)
height, width, channels = frame.shape
fourcc = cv2.VideoWriter_fourcc(*'mp4v')
out = cv2.VideoWriter(output, fourcc, 5.0, (width, height))
for image in images:
image_path = os.path.join(dir_path, image)
frame = cv2.imread(image_path)
out.write(frame)
out.release()

and also keep the haarcascade_frontalface_default.xml file and the python script in one folder, it is very important! I hope this helps!
