yolov5调用ip摄像头时出现的问题

今天尝试使用yolov5-5.0做实时目标检测，但是当输入指令：

python detect.py --source http://192.168.xx.xx:xx/video --weights yolov5s.pt

(xx表示我自己的ip)
总会出现以下问题：
[ERROR:[email protected]] global D:\a\opencv-python\opencv-python\opencv\modules\videoio\src\cap.cpp (166) cv::VideoCapture::open VIDEOIO(CV_IMAGES): raised OpenCV
exception:

OpenCV(4.5.5) D:\a\opencv-python\opencv-python\opencv\modules\videoio\src\cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can’t find starting numb
er (in the name of file): http://192.168.3.100:8001/video in function ‘cv::icvExtractPattern’

Traceback (most recent call last):

AssertionError: Failed to open http://192.168.3.100:8081/video

在网上查阅了诸多资料也没能解决，直到在一篇博客中看到别人的指令是这样的

python detect.py --source http://admin:[email protected].x.x.x:x

突然想起来自己在pycharm的terminal直接点击ip摄像头的连接地址时会出现这样的弹窗：


这才发现自己的错误多么低级：没有ip摄像头的输入账号和密码。
于是在terminal重新输入：

python detect.py --source http://admin:[email protected]192.168.x.x:x --weights yolov5s.pt

成功！
