是否可以将视频流伪造为在 Skype、Lync 等中可见的虚拟摄像头？

发布于 2024-12-02 17:28:18 字数 7903 浏览 0 评论 0原文

我正在尝试为我的应用程序构建一个关键部分，其中我需要能够伪造虚拟摄像头视频流。我想要伪造为虚拟网络摄像头的视频流通过我的 PC 进行流式传输，我可以在其中设置来自网络摄像头或硬盘某个位置的视频源。总而言之，我可以在 WPF 中将其设置为 MediaElement.SourceProperty 或 Image.Source。

我在 tmhare.com 上看到了 Vivek 的 Vcam，一个 directshow 过滤器，看起来好像是与我正在寻找的东西非常相关。但我找不到用VS2010编译它的方法，我也不知道该怎么办。我想我需要更改输入引脚，但是如何更改？

无论如何，总而言之，我正在尝试构建一个需要像 ManyCam 的小版本一样工作的部分代码。我正在构建一个 WPF 应用程序，在其中从 64 位 PC 流式传输源代码。

我也很感激过滤器的一些示例代码，因为我几乎忘记了我所知道的关于 C++ 的一切，因为 DirectShow 过滤器需要用 C++ 编写......

感谢一切！

I'm trying to build a crucial part for my application in which I need to be able to fake a virtual cam video stream. The video stream that I want to fake as a virtual webcam is streamed through my PC, where I can set the video source from my webcam or somewhere from my hdd. To sum up, something I can set as MediaElement.SourceProperty or Image.Source in WPF.

I've seen Vivek's Vcam, a directshow filter here in tmhare.com which seems like it is extremely related to what I'm looking for. But I couldn't find a way to compile it with VS2010, I also don't really know what to do with it. I think I need to change the input pin but how?

Anyhow, to sum up, I'm trying to build a partial code that needs to work like a small version of ManyCam. I'm building a WPF application where I stream the source from a 64 bit PC.

I would also appreciate some sample code for the filter since I have nearly forgotten everything I ever knew about C++ since DirectShow filter needs to be written in C++...

Thanks for everything!

为了使用 directshow 过滤器，您需要安装 Windows SDK 并编译 BaseClasses 解决方案。
查看： C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\multimedia\directshow\baseclasses

然后，您需要将 BaseClasses 头文件和 libs 目录添加到项目属性中。

现在您的项目将了解 DirectShow 类，并且您可以开始更改 VCam 源过滤器引脚。
