这是我正在使用的代码：

 import cv2 
from time import time
import socket
from goprocam import GoProCamera, constants

WRITE = False
gpCam = GoProCamera.GoPro()
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
t=time()
gpCam.livestream("start")
gpCam.video_settings(res='1080p', fps='30')
gpCam.gpControlSet(constants.Stream.WINDOW_SIZE, constants.Stream.WindowSize.R720)
cap = cv2.VideoCapture("udp://10.5.5.9:8554", cv2.CAP_)
counter = 0
while True:
    ret, frame = cap.read()
    cv2.imshow("GoPro OpenCV", frame)
    #if WRITE == True:
        #cv2.imwrite(str(counter)+".jpg", frame)
        #counter += 1
        #if counter >= 10:
            #break
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
    if time() - t >= 2.5:
        sock.sendto("_GPHD_:0:0:2:0.000000\n".encode(), ("10.5.5.9", 8554))
        t=time()
# When everything is done, release the capture
cap.release()
cv2.destroyAllWindows()

当我运行代码时，相机连接并显示实时画面，但终端给了我这个：

我怀疑它与这条线有关：

cap = cv2.VideoCapture("udp://10.5.5.9:8554", cv2.CAP_FFMPEG)

但我不确定。

此外，实时馈送非常缓慢且模糊，但我认为这只是无线连接的结果。有人对如何阻止这些错误有任何建议吗？
