关于DShow开发摄像头程序问题

新版的VS2010虽然包含了DirectShow，但文件并不齐全。
在使用 ISampleGrabber操作视像头视频捕捉时，会出现  streams.h qedit.h  mtype.h
找不到的问题。


下载完整的windows   sdk包， E:\Program Files\Microsoft SDKs\Windows\v7.1\Samples\multimedia\directshow\baseclasses 
包含streams.h   mtype.h
并且打开该目录下的baseclasses项目文件编译各个版本。


qedit.h 内容如下，自己手动创建头文件并放至C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include
