从预编译的二进制文件安装OpenCV，从github下载opencv-4.8.0-windows.exe 编译好的文件。按照官方文档拖入cv2.pyd文件。
https://docs.opencv.org/4.8.0/d5/de5/tutorial_py_setup_in_windows.html
拖入cv2.pyd和opencv_world480.dll之后执行程序报错
[ERROR:0@0.550] global cap.cpp:645 cv::VideoWriter::open VIDEOIO(CV_IMAGES): raised OpenCV exception:
OpenCV(4.8.0) C:\GHA-OCV-1_work\ci-gha-workflow\ci-gha-workflow\opencv\modules\videoio\src\cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can’t find starting number (in the name of file): output.avi in function ‘cv::icvExtractPattern’
之前发现缺少opencv_world480.dll动态库，找到之前解压opencv文件夹，查找所需动态库。我是拖到了site-packages文件夹下。系统路径能找到即可。
运行出现新错误之后，我在opencv目录，发现其它dll文件，一起拖到site-packages目录，解决报错。看情况应该时确实支持库。
opencv_videoio_ffmpeg480_64.dll
opencv_videoio_msmf480_64.dll
opencv_videoio_msmf480_64d.dll
碰到相识问题，可以考虑依赖问题。
