Original Vivek's popular sample project implementing virtual DirectShow video source filter

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.

1. The project requires DirectShow BaseClasses, which is a part of Windows SDK moved to github. 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.
2. Then, edit directshow.props and modify line with WindowsClassicSamplesDir to have it point to root of repository from step 1 above
3. Then, open vcam.sln and build this project

Differences from original version:

• output file name is Filters.dll (unlike original VCam.ax)
• the project is extended to have x64 platform configuration

How to use

Use Widows 10 SDK GraphEdit or GraphStudioNext.
