NDI-Browser v2026.10.29

Added

• Integrated Dark Mode Navigation Bar & Custom Window Frame (Avalonia UI):
  • Migrated the desktop preview window to Avalonia UI with Semi.Avalonia dark theme styling.
  • Extended client area into the title bar (ExtendClientAreaToDecorationsHint="True" and ExtendClientAreaChromeHints="NoChrome") with full drag support on empty title bar regions.
  • Implemented unified dark header bar (#141414 background, #2D2D2D border) integrating:
    • Dynamic application title section: [Page Title] - NDI Browser (WidthxHeight) with icon.
    • Navigation buttons: Back (◀), Forward (▶), and Reload (⟳) with history state tracking.
    • Responsive dark address bar with rounded corners (CornerRadius="4"), auto-selection on focus, bi-directional URL synchronization on AddressChanged, and Enter key submission without keystroke leaking to OSR.
    • Window management controls: Minimize (—), Maximize/Restore (🗖/🗗), and Close (✕) with red hover highlight (#E81123).
  • Added BrowserViewControl for hardware-accelerated Skia rendering of CEF OSR BGRA frame buffers and pointer/keyboard input forwarding.
  • Introduced IBrowserPreviewWindow abstraction to decouple preview presentation from the core Chromium rendering pipeline.

NDI-Browser v2026.10.27

Added

• Interactive Desktop Preview Window:
  • Added BrowserPreviewForm providing a live, resizable desktop window rendering off-screen (OSR) Chromium output.
  • Supports full input forwarding: mouse moves, left/right/middle clicks, mouse wheel scrolling, and keyboard input (KeyDown, KeyUp, and KeyPress text input).
  • Coordinates scale proportionally between preview window dimensions and Chromium canvas size.
  • Preview window runs on a dedicated STA thread and can be closed without interrupting or stopping the NDI stream.
  • Added CLI flags --preview / --enable-preview and --disable-preview.
  • Added a "Preview Window" checkbox to the graphical launcher (LauncherForm), enabled by default and persisted in LauncherSettings.
• Automatic Webcam & Microphone Permission Granting:
  • Added CustomPermissionHandler implementing IPermissionHandler to automatically grant media access (MediaAccessPermissionType) and UI permission prompts without blocking user interaction.
  • Added Chromium command-line switches enable-media-stream and use-fake-ui-for-media-stream to automatically select and use system default capture devices without browser infobar prompts.
