OpenCV（4.1.1）在函数“cv:：icvExtractPattern”中找不到起始编号（文件名）：（摄像头\u流\u Url）

Question

>&燃气轮机；我的py脚本运行正常，但当我创建.py to.exe时，生成了以下错误。

OpenCV（4.1.1）C:\projects\OpenCV python\OpenCV\modules\videoio\src\cap_images.cpp:253:错误：（-5:错误参数）cap_images:在函数“cv:：icvExtractPattern”中找不到起始编号：http://admin:admin@192.168.1.86/axis-cgi/mjpg/video.cgi

下面是我的py脚本及其生成。
