What is a Virtual Webcam?
A virtual webcam (also known as a virtual camera) is a software-based camera that simulates a physical webcam device on your Windows PC. This allows you to send video and audio from any source—such as video files, network streams, webcams, camcorders, or even your desktop screen—to popular applications like Zoom, Skype, OBS Studio, Google Meet, Microsoft Teams, and many more.
With a virtual webcam, you can:
- Use pre-recorded videos, live streams, or custom video effects as your webcam input.
- Share your desktop, presentations, or application windows as a webcam feed.
- Combine multiple video sources and switch between them seamlessly.
- Apply real-time video effects, overlays, and branding to your video stream.
- Use your virtual camera in multiple applications at the same time, thanks to multi-instance support.
This technology is ideal for live streaming, video conferencing, online teaching, webinars, remote collaboration, and any scenario where you want to control or enhance your video presence.

C# Code Example
Here's a practical example of how to use the Virtual Camera SDK in a .NET application:
Project Setup
Create a new .NET project and add the VisioForge.DirectShowAPI NuGet package:
.csproj Configuration
XMLImplementation Example
This example demonstrates how to capture video from a physical camera and stream it through a virtual camera:
VirtualCameraExample.cs
C#This example shows:
- Setting up a DirectShow filter graph
- Enumerating and selecting video capture devices
- Creating and connecting source and virtual camera filters
- Managing the streaming lifecycle
- Proper resource cleanup
For more advanced features like video effects, format selection, and multiple instances, refer to our comprehensive SDK documentation.
C++ DirectShow Example
