Windows 10: Project and build structure for Microsoft DirectShow based virtual webcam application on...

I am trying to create simplest virtual webcam application which can display image file on my local filesystem.

After initial research on stackoverflow links and seeing OBS Studio source code I got some idea how can I achieve this.

1. I would need to use Microsoft DirectShow.
2. I would need to develop one source filter that would work as capture filter using IBaseFilter
3. I would need to develop another source filter that would work as output filter or virtual webcam filter. I would need to compile this filter as .dll file and will need to register using regsvr32.exe
   As given on https://docs.microsoft.com/en-us/windows/win32/directshow/building-directshow-filters
4. I would need to create Filter Graph and Capture Filter Graph using CoCreateInstance like
   hr = CoCreateInstanceCLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER, IID_IFilterGraph, void **&graph;
   hr = CoCreateInstanceCLSID_CaptureGraphBuilder2, NULL, CLSCTX_INPROC_SERVER, IID_ICaptureGraphBuilder2, void **&builder;
5. Then I would need to add these filters to Filter Graph
6. Then I would set Filter Graph to Capture Filter Graph like hr = builder->SetFiltergraphgraph;

Here is my confusion now:
After these steps I am not sure if I have to wrap these Graph Filters and Capture Graph Filter in one application which would be having main method and compile it to get .exe file or I need to compile as another .dll file.

Or How should I wrap these steps to create final application?

Microsoft and Dassault Systèmes Launch Microsoft Virtual Earth -3DVIA

Dassault Systèmes (DS), a world leader in 3-D and product life-cycle management (PLM) solutions, and Microsoft Corp. today launched Microsoft Virtual Earth -3DVIA (Technology Preview). This free online application, developed by Dassault Systèmes, allows consumers to imagine and create realistic 3-D models — such as of buildings and structures — then share them through Microsoft Virtual Earth and online communities.


“Virtual Earth -3DVIA users will be able to build a world that mixes their future projects and ideas with real-life places, buildings and structures,” said Lynne Wilson, senior vice president and general manager of 3DVIA at Dassault Systèmes. “Through Microsoft’s online geographic location mapping technology and our 3-D modeling and realistic visualization know-how, we have created a new level of realism within Virtual Earth that provides an unrestricted freedom for creativity and innovation.”

Users can download Virtual Earth -3DVIA for free and immediately begin using the fun, easy-to-use and intuitive application. Virtual Earth -3DVIA allows anyone to do the following with their ideas:

• Create. With just a few clicks, users can easily design a 3-D model of their house, favorite building or any structure, then select from different visualization options, textures and colors to give their 3-D model a style of its own.
• Publish. Users can upload their 3-D models to Virtual Earth, specifying an address or neighborhood so they can experience the model within a real-life context.
• Share. Users can add their 3-D model to collections, and share it with friends and colleagues through Web communities.

“Our alliance with Dassault Systèmes, a company that has 26 years of technology experience in 3-D modeling, will help us bring a new level of realism to Virtual Earth,” said Stephen Lawler, general manager of Virtual Earth at Microsoft. “Microsoft is committed to delivering the highest-quality product for our Virtual Earth customers, and this enhancement is another step toward fulfilling that commitment.”

Virtual Earth -3DVIA is being released as a technology preview to allow community feedback before the next release of the product. More information about Virtual Earth -3DVIA is available online at Karten.

C# Web Webcam Capture Help

Hello all. I stumbled across this project: http://kristoffer.vinther.name/projects/managed-directshow/ which could be used in a project I've been wanting to take on for a while now. However, when I set up the "Camcorder" application to capture from a webcam source as shown on the project's page, I get this error from visual studio 2010:

pointing to this line:
Code: this.asfRecorder1.Record();[/quote] When I investigate the error further, VS2010 tells me it's looking for "String what" and "Records string contents to a file"

The help online says "String
A designation of what is to be recorded, e.g. the title of a show. " - http://kristoffer.vinther.name/proj...DirectShow.Components.AsfRecorderMembers.html and http://kristoffer.vinther.name/proj...tShow.Components.FileRecorderBase.Record.html

If anyone can help me make sense of this, It is greatly appreciated. Thanks in advance.
