Virtual Camera SDK

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.

VisioForge Virtual Camera SDK stands out as a leading solution for virtual webcam functionality on Windows. Here's why:

• Easy SDK Integration: Add virtual webcam features to your own Windows applications with our comprehensive SDK.

• Virtual webcam not recognized? Ensure the SDK is installed and selected as the video input in your application. Restart the app if needed.
• Choppy video or audio? Close other resource-intensive programs or check your system resources and internet connection.
• Compatibility issues? Some applications may require updates or specific settings. Contact our support team for assistance.
• Need help? Access our detailed documentation, FAQs, or reach out to our priority support team for personalized help.

• e2eSoft VCam: Both offer virtual webcam functionality, but VisioForge provides deeper DirectShow integration, more advanced video processing, and developer-friendly SDK features.
• OBS Studio Virtual Camera: OBS is great for streaming, but VisioForge SDK is designed for easy integration into your own apps and offers more granular control for developers.
• ManyCam, YouCam, etc.: These are end-user apps, while VisioForge SDK is ideal for developers and businesses looking to embed virtual webcam features into their own products.

Here's a practical example of how to use the Virtual Camera SDK in a .NET application:

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.

Here's a complete example showing how to capture video and stream it through the virtual camera:

This C++ example demonstrates:

• DirectShow filter graph setup and management
• Video capture device enumeration
• Virtual camera filter creation and configuration
• Filter connection and streaming control
• Proper COM resource cleanup
• Error handling and status reporting

The example uses standard DirectShow interfaces along with the Virtual Camera SDK's custom interfaces for advanced functionality. Make sure to:

1. Link against the DirectShow libraries
2. Include the necessary DirectShow headers
3. Initialize and uninitialize COM appropriately
4. Handle all COM interface releases properly

For advanced features like video format selection, multiple instances, or video effects, refer to our SDK documentation.

We maintain a comprehensive collection of sample projects on GitHub to help you get started with the Virtual Camera SDK. Visit our DirectShow Samples Repository for complete, working examples.

The samples are available in multiple programming languages:

• C# (.NET)
• C++ (Native DirectShow)
• Delphi
