有没有显示如何编写DirectShow转换过滤器的示例？ [英] Is there any example to show how to write a DirectShow transform filter?

问题描述

我想捕获当前框架及其前一个框架以进行分析并生成一个新的框架来显示。是说我必须编写一个转换DirectShow过滤器吗？但是我是DirectShow的新手。我对MSDN的许多文档感到困惑。因此，我想知道是否有任何简单的示例来演示如何做到这一点。

I want to capture a current frame and its previous one to do analysis and produce a new frame to show. Is it to say I must write a transform DirectShow filter? But I am a newbie to DirectShow. I was confused by MSDN's lots of documents. So I wonder if there is any simple example to show how to do it.

谢谢。

推荐答案

在Platform SDK随附的DirectShow示例中，至少，您总是习惯于获取示例关于如何制作各种过滤器。我不敢相信他们会删除它。它使DirectShow几乎可用：）

In the directshow samples that come with the Platform SDK you, at least, always USED to get examples on how to make all sorts of filters. I can't believe they would have removed that. It made DirectShow almost usable :)
