A full line of on-device AI blocks — object detection, face recognition, OCR/ANPR, background removal, custom ONNX inference, and offline Whisper transcription — is now available across Media Blocks SDK .NET, Video Capture SDK .NET, and Media Player SDK .NET. The same block instances register into a custom MediaBlocksPipeline, straight into live capture through VideoCaptureCoreX, or straight into playback through MediaPlayerCoreX — no separate pipeline to manage either way. Every model runs locally through ONNX Runtime and Whisper.net, so nothing is ever sent off the device.
•Object Detection & Analytics: Run YOLOv8, YOLOX, or RT-DETR models to detect and label objects in real time, whether the source is a live camera feed, a custom pipeline, or a file you're replaying for review. Add ByteTrack to assign persistent IDs to each object across frames, then layer on line-crossing counters and polygon zone occupancy alerts to turn raw detections into usable analytics — footfall counts, perimeter breaches, dwell-time zones. Detections render as overlays directly on the video, and the same analytics work whether you're watching a live feed or replaying an archived recording for forensic review.
•Face Recognition: Detect faces in a frame, enroll identities into a FaceGallery, and match incoming faces against that gallery — live from a camera, inside a custom pipeline, or against footage you've already recorded. Recognized people are labeled directly on the video, which makes the same block useful for access control at a gate, monitoring dashboards that flag known individuals, and after-the-fact searches through archived recordings to find every appearance of a given person.
•OCR & License Plate Recognition (ANPR): PaddleOCR-based blocks read on-screen text and vehicle license plates and turn them into structured detection events your application can act on programmatically — a decoded string with a bounding box and confidence score, not just an image. That covers gate cameras and parking barriers reading plates in real time, signage or storefront monitoring, and pulling text or plates out of recorded footage for archival indexing or investigations.
•Background Removal: ONNX matting models remove, blur, or replace the background behind a subject without a green screen — solid color, a custom image, or a fully transparent RGBA output for compositing. On a live webcam or streaming feed this powers virtual backgrounds and privacy blurring in real time; inside a custom pipeline it's just another block dropped between your source and your output.
•Offline Speech-to-Text & Captions: Whisper transcribes audio entirely on-device — no cloud call, no API key — with Silero VAD trimming silence so segments stay clean. Use it live while recording to burn captions into the output as it happens, or point it at a file's existing audio track to generate subtitles for footage that was never captioned in the first place. Either way, render live captions on screen or export the result as SRT or VTT files.
•Custom ONNX Inference: Attach your own ONNX model to the video pipeline and get raw tensor output back for whatever post-processing your application needs — the escape hatch for detection or classification tasks that don't fit the built-in blocks. Uses the same block-registration mechanism as everything else here, so it plugs into a custom pipeline, live capture, or playback just as easily.
VisioForge .NET SDKs now run directly inside the Unity game engine. You can embed real-time video playback, webcam and IP camera capture, RTSP streaming, and timeline video editing into your Unity projects — frames render straight into Unity textures through the VisioForgeVideoView control and the OnVideoFrameUnity event. Support is delivered through the X engines (MediaBlocksPipeline, MediaPlayerCoreX, VideoCaptureCoreX, and VideoEditCoreX) and ships as a single cumulative .unitypackage targeting .NET Standard 2.1, with cross-platform builds for Windows, Android, macOS, and iOS. Hardware-accelerated decoding and a developer-friendly C# API make it easy to add professional video features to games, AR/VR apps, digital signage, and surveillance dashboards. Unity support is available in Media Blocks SDK .NET, Media Player SDK .NET, Video Capture SDK .NET, and Video Edit SDK .NET. See the Unity page and our step-by-step Unity guides to get started.
Our February 2026 release brings 10 major new features across Media Blocks SDK and Video Capture SDK .NET.
•Pre-Event Recording: Circular buffer video recording for surveillance — continuously buffer the last N seconds and save footage before an event trigger. Supports MP4, MPEG-TS, and MKV.
•Network Disconnect Detection: New OnNetworkSourceDisconnect event for RTSP, HTTP, SRT, NDI, and RTMP sources, enabling automatic reconnection workflows.
•WebRTC WHIP Output: Low-latency browser streaming via WebRTC-HTTP Ingestion Protocol for real-time web delivery.
•RIST MPEG-TS Sink: Reliable Internet Stream Transport for dependable streaming over lossy networks with error correction.
•ElevenLabs AI Voice: Text-to-speech synthesis and voice cloning directly in media pipelines via new ElevenLabsSynthesizerBlock.
•WebView2 Overlays: Render live web content (HTML/CSS/JS) as video overlays for broadcast and streaming applications.
•H264 Push Source: Push raw H.264 encoded data into decoding pipelines with automatic AVC-to-byte-stream conversion and PTS rebasing.
•Fast RTSP Discovery: New lightweight RtspDescribeClient achieves ~100-200ms stream setup (10x faster) with Basic/Digest authentication.
•Image Sequence Overlays: Per-frame durations, looping, position/size animation, fade effects, and easing support for animated overlays.
•Screen Capture Mouse Clicks: Mouse click highlight support for screen capture with real-time settings updates.
•Windows ARM64: Full native ARM64 Core binaries now available on Windows via NuGet.
We've introduced a modern certificate-based licensing system for Video Capture SDK .NET, Video Edit SDK .NET, Media Blocks SDK .NET, and Media Player SDK .NET. The new system uses .vflicense certificate files with RSA-2048 digital signatures, replacing the previous license key approach. Two license types are available: Developer licenses for development machines with online activation, and Release licenses that work completely offline for production deployment. Integration is straightforward — load the certificate from a file with SetLicenseCertificateAsync() or embed it as a resource using SetLicenseCertificateDataAsync(). Existing customers can migrate their legacy license keys to the new certificate format. Visit our updated registration guide for complete setup instructions and code examples.
We're excited to introduce Pre-Event Recording (circular buffer recording) in VisioForge Media Blocks SDK and Video Capture SDK .NET. This key surveillance feature continuously buffers the last N seconds of encoded video and audio in memory. When an event triggers — such as motion detection, an alarm, or an API call — the buffered pre-event footage is written to a file along with post-event recording, creating complete event clips that never miss critical moments. Features include configurable buffer duration (default 30 seconds), keyframe-aware recording that always starts from the nearest I-frame, automatic post-event timer with extend-on-re-trigger support, thread-safe circular buffer with minimal memory footprint (~15 MB per camera at 4 Mbps), and multiple container formats including MP4, MPEG-TS (crash-safe), and MKV. The PreEventRecordingBlock integrates seamlessly into any MediaBlocks pipeline, and a high-level API is available through VideoCaptureCoreX for quick integration. Check our documentation for complete code samples with motion detection and RTSP camera support.
