Initial public release of VirtualDisplayKit.

VirtualDisplayKit is a Swift Package derived from Stengo/DeskPad (MIT-licensed), extended into a modular, reusable package with video recording, RTMP-ready streaming output, and SwiftUI/AppKit view integrations. See ATTRIBUTION.md for the full derivation breakdown.

What's included

  • VirtualDisplay — create and manage virtual displays via the private CGVirtualDisplay API
  • VirtualDisplayConfiguration — configurable resolution, refresh rate, HiDPI support, vendor/product identifiers, and preset configurations (.preset1080p, .preset1080pPortrait, .preset4K, .preset4KPortrait)
  • DisplayStreamRenderer — CGDisplayStream-based frame delivery with both IOSurface and CVPixelBuffer output paths
  • DisplayRecorder — record virtual display content to H.264/HEVC MP4/MOV via AVAssetWriter; .standard, .highQuality, and .hevcHighEfficiency presets
  • FrameOutputStream — emit encoded H.264/HEVC Annex-B or raw CVPixelBuffer frames for RTMP streaming, OBS integration, or custom pipelines, via VTCompressionSession; .rtmpStreaming, .highQuality, .realtime presets
  • VirtualDisplayController — high-level facade combining display, recording, and streaming
  • VirtualDisplayView (SwiftUI) and VirtualDisplayNSView (AppKit) for preview integration
  • MouseTracker — cursor position mapping between preview view and virtual display coordinate space
  • Demo app at Virtual Display.xcodeproj demonstrating all features
  • Examples for SwiftUI, AppKit, and digital signage use cases
