So I tried running this code.. I have a LOGITECH webcam, and it works fine with the imshow, however when I added the VideoWriter feature to save the video feed, the video file appears but is not playable... Can anyone help me with this? Thank you!
import cv2
import sys
import logging as log
import datetime as dt
from time import sleep
cascPath = "haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascPath)
log.basicConfig(filename='webcam.log',level=log.INFO)
video_capture = cv2.VideoCapture(0)
anterior = 0
video_capture.set(3, 240)
video_capture.set(4, 240)
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('-Vid.avi', fourcc, 10, (240,240))
while True:
if not video_capture.isOpened():
print('Unable to load camera.')
sleep(5)
pass
ret, frame = video_capture.read()
if ret:
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
faces = faceCascade.detectMultiScale(
gray,
scaleFactor=1.1,
minNeighbors=5,
minSize=(30, 30)
)
for (x, y, w, h) in faces:
cv2.rectangle(frame, (x, y), (x+w, y+h), (0, 255, 0), 2)
if anterior != len(faces):
anterior = len(faces)
log.info("faces: "+str(len(faces))+" at "+str(dt.datetime.now()))
cv2.imshow('Video', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cv2.imshow('Video', frame)
out.write(frame)
else:
break
video_capture.release()
out.release()
cv2.destroyAllWindows()
