它的记录很少，但演示了如何访问 DirectShow 用于从视频流中捕获帧（甚至对其进行一些操作）的 API，正如一些人提到的，这是现代 Windows 系统的方法。
I wanted to be able to get a video stream from a webcam using Python in Windows. I found this VideoCapture library, but it didn't work in Python 2.6, so I ended up porting his library to Python using ctypes and comtypes called jaraco.video.
It's sparsely documented, but demonstrates how one would access the DirectShow APIs to capture frames from a video stream (and even do some manipulation on it), which as some have mentioned, is the way to go for modern Windows systems.
这可能是因为 Windows 视频已被弃用一段时间了。它已被 DirectShow 库取代，后者处理视频捕获和编码任务。
That would probably because Video for Windows is deprecated for some time now. It has been replaced with DirectShow libraries, which handle the video capture and encoding tasks.

根据 这篇 Wikipedia 文章，VFW 的最后一个版本是 1996 年的 NT4。换句话说，这是过时的技术。
According to this Wikipedia article, the last release of VFW was in 1996 for NT4. In other words, this is obsolete technology.
我希望能够在 Windows 中使用 Python 从网络摄像头获取视频流。我找到了这个VideoCapture库，但它在Python 2.6中不起作用，所以我最终移植了他的库使用名为 jaraco.video 的 ctypes 和 comtypes 转换为 Python。
