Video Capture SDK for .NET Developers

Video Capture SDK .Net

Introduction

Our Video Capture SDK for .NET equips developers with a powerful, versatile solution for implementing professional-grade video recording capabilities in their applications. Designed specifically for .NET environments, this SDK provides seamless integration with your existing codebase while delivering exceptional performance and reliability.

Quick Start — Record webcam to MP4

Minimum end-to-end path with VideoCaptureCoreX (cross-platform). Swap the MP4Output for MKVOutput / WebMOutput / MOVOutput to switch container, or for RTSPServerOutput / RTMPOutput / HLSOutput to stream instead of record — the surrounding wiring stays the same.

using VisioForge.Core;
using VisioForge.Core.Types;
using VisioForge.Core.Types.X.Output;
using VisioForge.Core.Types.X.Sources;
using VisioForge.Core.VideoCaptureX;

// 1. Initialise the cross-platform engine once per process.
VisioForgeX.InitSDK();

// 2. Create the engine, bound to an IVideoView for preview (or null for headless).
var videoCapture = new VideoCaptureCoreX(videoView as IVideoView);

// 3. Select first enumerated camera + microphone.
var videoDevice = (await DeviceEnumerator.Shared.VideoSourcesAsync()).First();
var audioDevice = (await DeviceEnumerator.Shared.AudioSourcesAsync()).First();
videoCapture.Video_Source = new VideoCaptureDeviceSourceSettings(videoDevice);
videoCapture.Audio_Source = new AudioCaptureDeviceSourceSettings(audioDevice);
videoCapture.Audio_Record = true;

// 4. Add an MP4 output. Defaults to H.264 + AAC.
videoCapture.Outputs_Add(new MP4Output("output.mp4"), true);

// 5. Start. OnError fires on pipeline errors.
await videoCapture.StartAsync();

Key Capabilities

  • Multi-source capture - Record from webcams, capture cards, and other video devices
  • Real-time processing - Apply filters and effects during capture
  • Customizable quality settings - Control bitrate, framerate, and resolution
  • Event-driven architecture - Respond to capture events in your application
  • Multi-platform support - Works across Windows desktop environments

Extensive Format Support

Our SDK supports a comprehensive range of output formats to meet diverse project requirements, ensuring your applications can deliver video in exactly the format your users need:

Standard Video Formats

  • MP4 (H.264/AAC) - Industry standard format offering excellent compatibility across devices and platforms, ideal for distribution and streaming applications
  • WebM - Open-source format optimized for web applications with efficient compression and broad browser support
  • AVI - Classic container format with widespread compatibility and minimal processing overhead, supporting virtually any DirectShow-compatible codec
  • WMV - Microsoft's video format providing good compression ratios and integration with Windows environments

Professional & Broadcast Formats

  • MKV (Matroska) - Flexible container format supporting multiple audio, video, and subtitle tracks, ideal for archiving and high-quality storage
  • MOV (QuickTime) - Apple's container format widely used in professional video editing and production workflows
  • MPEG-TS (Transport Stream) - Format optimized for broadcasting and streaming applications with robust error correction
  • MXF (Material Exchange Format) - Professional video production format used in broadcast and post-production environments

Specialized Output Options

  • GIF (Graphics Interchange Format) - Perfect for creating short, looping animations with wide web compatibility
  • DV (Digital Video) - Professional-grade format commonly used with digital camcorders, preserving high-quality video for editing workflows
  • FFMPEG Integration - Advanced encoding options leveraging the powerful FFMPEG library for specialized encoding requirements
  • Custom Output Solutions - Create your own format specifications and processing pipelines for unique application needs

Hardware-Optimized Capture

Advanced Video Encoders

Our SDK incorporates multiple advanced video encoders to provide optimal compression efficiency and performance for different capture scenarios:

Modern High-Efficiency Encoders

  • H.264 (AVC) - Industry-standard encoder offering excellent compatibility and multiple hardware acceleration options from NVIDIA, AMD, and Intel
  • HEVC (H.265) - Next-generation encoder providing ~50% better compression than H.264 with support for 4K and HDR content
  • AV1 - Royalty-free open standard delivering superior compression efficiency, ideal for web streaming applications

Specialized & Legacy Encoders

  • MJPEG - Motion JPEG encoder providing low-latency frame-by-frame compression with hardware and software implementations
  • VP8/VP9 - Google's open-source codecs offering competitive quality-to-bitrate ratios for WebM containers

Hardware Acceleration Support

Our encoders support hardware acceleration from major vendors:

  • NVIDIA NVENC - GPU-accelerated encoding with minimal CPU usage
  • AMD AMF - Advanced Media Framework for efficient AMD GPU encoding
  • Intel QuickSync - Intel's hardware-accelerated video processing
  • Software Fallbacks - Comprehensive software implementations when hardware acceleration isn't available
