Im trying to get some pictures with facedetection with my raspberry with the code below
import cv2
import time
count = 0
faceCascade = cv2.CascadeClassifier('/home/pi/haarcascade_frontalface_alt.xml')
cv2.VideoCapture('http://***/videostream.cgiuser=**&pwd=**&resolution=32&rate=0')
while True:
ret, frame = video_capture.read()
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
faces = faceCascade.detectMultiScale(
gray,
scaleFactor=1.1,
minNeighbors=5,
minSize=(30, 30),
flags=cv2.CASCADE_SCALE_IMAGE
)
for (x, y, w, h) in faces:
cv2.rectangle(frame, (x, y), (x + w, y + h), (0, 255, 0), 2)
file_name = '/home/pi/faces_detected/frame%s_%s.png' %(count, str(time.time())[11:])
cv2.imwrite(file_name, frame)
count += 1
if cv2.waitKey(1) & 0xFF == ord('q'):
break
when I run with python, i got the error several times
[mp3 @ 0xe6b3c0] Header missing
[mp3 @ 0xe6b3c0] Header missing
[mp3 @ 0xe6b3c0] Header missing
[mp3 @ 0xe6b3c0] Header missing
[mp3 @ 0xe6b3c0] Header missing
I do not use any audio on the code, why I got this error?
