如何在Windows 7中访问网络摄像头 [英] How to access the Webcam in Windows 7

问题描述

我正在尝试编写一个简单的程序，将网络摄像头中的视频转换为ASCII文本，例如ASCII艺术视频.我目前拥有Visual Studio 2008，并将很快升级到VS2010.我的机器是Windows 7、64位.我的问题是，我可以使用哪个SDK，该SDK允许我从网络摄像头中获取帧，处理这些帧，然后将它们显示在窗口中.我知道，如果我在2005年会问这个问题，我只会使用avicap32.dll.但是据我了解，这已被Microsoft Media Foundation取代.在Media Foundation中，从网络摄像头框架中提取RGB数据并将其转换为文本似乎非常困难.所以我的问题是，我应该使用什么?我应该尝试返回并使用DirectShow库吗?

I am trying to write a a simple program that converts video from my webcam into ASCII text, like an ASCII art video. I currently have Visual Studio 2008, and will soon upgrade to VS 2010. My machine is Windows 7, 64 bit. My question is, which SDK can I use which will allow me to take frames from my webcam, process the frames, and then display them in a window. I know that if I would have asked this question in 2005, I would simply use avicap32.dll. As I understand it, though, this has been superceded by Microsoft Media Foundation. Extracting RGB data from a webcam frame and converting to text seems really difficult in Media Foundation. So my question is, what should I use? Should I try to go back and use the DirectShow libraries?

Thanks in advance!
