视频捕获过滤器属性 [英] Video Capture Filter Properties

问题描述

我正在寻找有关阅读或更新VB.NET中的视频捕获过滤器属性的帮助/示例.

 I'm looking for some help/examples on reading or updating the video capture filter properties in VB.NET.

我正在使用Panasonic Toughbook上的USB视频设备.相机具有许多功能，用户可以在运行强韧本附带的软件时进行设置(缩放，亮度，对比度等)

I am working with a USB video device that came on a Panasonic Toughbook.  The camera has alot of functions that the user can set when running the software that came with the toughbook (zoom, bightness, contrast, etc)

我可以触发快门，将图片传输到任何位置，然后将图片重新读回到我的应用程序中，而在WIA中没有任何麻烦.我无法在VB中找到一种方法来读取相机的属性以根据我们的应用程序的需要对其进行更新.

I can trigger the shutter, transfer the picture to any location, and reread the picture back into my application all with no trouble in WIA.  I can not find a way in VB to read the properties of the camera to update them with our application's needs.

我使用DirectShow编译了Windows SDK中的c ++ AmCap程序.该编译程序能够为用户提供属性以供他们调整，因此我知道可以做到.我似乎无法理解它的位置和方式.

I have complied the c++ AmCap program that was part of the Windows SDK with DirectShow.  That compiled program is able to offer the Properities to the user for them to adjust, so I know it can be done.  I just can't seem to understand the where and how of it. 

有帮助吗?

谢谢
