Question

我在使用 GStreamer 功能从源代码构建 OpenCV 时遇到了这个错误。这是错误：

Python 3.8.7 (tags/v3.8.7:6503f05, Dec 21 2020, 17:59:51) [MSC v.1928 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Program Files\Python38\lib\site-packages\cv2\__init__.py", line 102, in <module>
 bootstrap()
File "C:\Program Files\Python38\lib\site-packages\cv2\__init__.py", line 90, in bootstrap
 import cv2
ImportError: DLL load failed while importing cv2: Belirtilen modül bulunamadı.
>>>

我的设置是：
Gstreamer 1.18.2（我尝试了 MinGW 64 位和 MSVC 64 位相同的结果）
Python 3.8
OpenCV 4.5.1

到目前为止我做了什么：

我将正在加载模块的 init.py 文件更改为调试模式，这是我发现的：

>>> import cv2

OpenCV loader: replacing cv2 module
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\Python38\lib\site-packages\cv2\__init__.py", line 102, in <module>
    bootstrap()

    import cv2
ImportError: DLL load failed while importing cv2: Belirtilen modül bulunamadı.

我认为这是路径问题，因为我用 Dependency Walker 打开了 cv2.cp38-win_amd64.pyd 文件以查找丢失的 DLL，我发现许多看起来丢失的 DLL 都在 System32 文件夹中。 Missing DLLs
因为我认为这是一个路径问题，所以我的路径看起来不错。当我在没有 GStreamer 功能的情况下构建 OpenCV 时，它完全正常工作。即使我使用额外的 contrib 模块和 CUDA 构建 OpenCV。我的用户和系统变量：

System PATHs
System and Enviroment Variables
User PATHs

我好几个星期都无法解决这个问题。我今天找到了另一个解决方案，但我真的希望 OpenCV 与 GStreamer 一起工作。如果有人能解决我会很高兴。
