是否可以伪造一个视频流作为虚拟凸轮在Skype，Lync等可见？ [英] Is it possible to fake a video stream as virtual cam that is visible in Skype, Lync etc?
本文介绍了是否可以伪造一个视频流作为虚拟凸轮在Skype，Lync等可见？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图为我的应用程序构建一个关键的部分，我需要能够伪造一个虚拟凸轮视频流。我想假装为虚拟网络摄像头的视频流通过我的电脑，我可以设置视频源从我的网络摄像头或某处从我的hdd。总而言之，我可以在WPF中设置为 MediaElement.SourceProperty或Image.Source 。
看到 Vivek的Vcam，在tmhare.com的directshow过滤器这似乎是非常相关的我在找。但我找不到一个方法来编译它与VS2010，我也不知道该怎么办。我想我需要更改输入引脚，但是如何？
总之，我试图构建一个需要像小版本一样工作的部分代码是什么意思？我正在构建一个WPF应用程序，我从一个64位PC流源。
我还会感谢一些滤镜的示例代码，因为我几乎忘记了所有关于C ++的知识，因为DirectShow过滤器需要用C ++编写... <感谢一切！

解决方案
使用directshow过滤器，您需要安装Windows SDK并完成BaseClasses解决方案。
查看： C：\Program Files \Microsoft SDKs \Windows \v7.0\ Samples \multimedia\directshow\baseclasses
之后，您需要将BaseClasses头文件和libs目录添加到项目属性中。
现在你的项目将知道DirectShow类，你可以开始更改VCam源过滤器pin。
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!

解决方案
In order to work with directshow filters, you need to have the Windows SDK installed and comiple the BaseClasses solution.
look at: C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\multimedia\directshow\baseclasses
Afterward you need to add the BaseClasses header files and libs directories to your project properties.
Now your project will know the DirectShow classes and you can start changing the VCam source filter pin.
