Video Capture SDK .Net is a powerful library designed specifically for .NET developers who need to implement webcam capture functionality in their applications. Whether you want to record webcam video, save webcam frames as images, or display the webcam feed in your application, this SDK has you covered. Some of its standout features include:
MP4 is one of the most widely supported video container formats, making it an excellent choice for applications where compatibility is a priority.
Supported codecs for MP4:
WebM is an open, royalty-free media file format designed for the web.
Supported codecs for WebM:
Each codec can be fine-tuned with various parameters to achieve the optimal balance between quality and file size for your specific application requirements.
One of the standout features of Video Capture SDK .Net is its robust support for GPU-accelerated video encoding, which offers several significant advantages:
Video Capture SDK .Net leverages multiple GPU acceleration technologies:
The SDK automatically detects available hardware and selects the optimal encoding path based on your system's capabilities, with fallback to software encoding when necessary.
Let's walk through a simple tutorial on how to record webcam video using C#. Implementing webcam capture with Video Capture SDK .Net is straightforward.
For WebM output with VP9 encoding, simply modify the encoder settings:
var webMOutput = new WebMOutput(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyVideos), "output.webm"));
videoCapture1.Outputs_Add(webMOutput);
Here's a simple example of how to just save a single image from the webcam.
Enable video sample grabber:
// Enable video sample grabber to make snapshots. Add these code before the StartAsync() method.
videoCapture1.Snapshot_Grabber_Enabled = true;
Get and save a single image from the webcam:
// Capture and save a single image from webcam
private async Task SaveSnapshotAsync()
{
var filename = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyPictures), "snapshot.jpg");
await videoCapture1.Snapshot_SaveAsync(filename, SkiaSharp.SKEncodedImageFormat.Jpeg);
}
Video Capture SDK .Net relies on native libraries to access webcam devices and perform video and audio processing. These native dependencies are bundled with the SDK and are automatically deployed with your application, ensuring seamless integration and compatibility across different systems.
Major SDK package (managed):
<ItemGroup>
<PackageReference Include="VisioForge.DotNet.VideoCapture" Version="2025.2.21" />
</ItemGroup>
Native dependencies for Windows x64:
<ItemGroup>

<PackageReference Include="VisioForge.CrossPlatform.Libav.Windows.x64" Version="2025.2.15" />
</ItemGroup>
For alternative platforms (macOS, Linux, Android, iOS), use the corresponding native dependencies packages.
Video Capture SDK .Net is designed with cross-platform compatibility in mind, making it an ideal choice for developers working on applications that need to run on multiple operating systems.
For developers working with .NET MAUI (Multi-platform App UI), Video Capture SDK .Net offers:
This cross-platform capability allows developers to write code once and deploy across Windows, macOS, and mobile platforms through MAUI, significantly reducing development time and maintenance overhead.
Video Capture SDK .Net provides a comprehensive solution for adding webcam video capture capabilities to your DotNet applications. Whether you need to record webcam footage, save webcam images, or simply display the webcam feed in your application, this library makes the process simple with just a few lines of C# code.
With support for industry-standard formats like MP4 and WebM, modern codecs including H.264/H.265 and VP8/VP9/AV1, and powerful GPU acceleration, it offers the performance and flexibility needed for even the most demanding video capture applications. The ability to create and save video files efficiently makes this library perfect for any application that needs to record webcam content.
The SDK's cross-platform compatibility, extending to macOS and MAUI applications, ensures that your webcam capture solution works consistently across different operating systems. Whether you're building a video conferencing tool, a surveillance application, or any other software requiring webcam functionality, Video Capture SDK .Net offers the tools you need to implement these features quickly.
