DirectShow VCam
This repository contains Vivek's Capture Source Filter filter, a popular DirectShow sample project, which recently celebrated its 16th anniversary (2005 posting reference).
Capture Source Filter filter (version 0.1) 86 KB zipped, includes binaries. A sample source filter that emulates a video capture device contributed by Vivek (rep movsd from the public newsgroups). Thanks Vivek! TMH has not tested this filter yet. Ask questions about this on microsoft.public.win32.programmer.directx.video.
This was hosted on The March Hare's website for quite some time, and now when the website is gone people don't know where to look for the source code. Here it goes!

Updates
Orignial source code is tagged by original tag. In this state the project needs a bit of massaging to be beuilt.
The head of the repository is updated for Virtual Studio 2019 Community builds.

For this reason you need to pull https://github.com/roman380/Windows-classic-samples/tree/directshow/Samples/Win7Samples/multimedia/directshow (note branch "directshow") first and build the directshow.sln solution there (or at least BaseClasses project) first.
- Then, edit directshow.props and modify line with
WindowsClassicSamplesDirto have it point to root of repository from step 1 above - Then, open vcam.sln and build this project
