NV Broadcast is an AI-powered virtual camera and voice enhancement app for Linux. It brings background blur, background replace, green-screen remove, eye contact correction, face relighting, video enhancement, recording, and local meeting transcription into one app.

What's new in v1.4.0: Global hotkeys, Gaze Lock, and reliable mode switching

• Adds rebindable Linux global shortcuts for effect toggles through the XDG GlobalShortcuts portal or a restricted GNOME fallback.
• Adds Natural and Gaze Lock Eye Contact modes with coordinated binocular targeting, blink fallback, and smooth head-pose updates.
• Switches physical cameras at runtime and applies profiles safely when a video backend can provide only one current frame.
• Rebuilds and atomically swaps RVM sessions during quality or processing mode changes, with clean CUDA recovery and CPU fallback.
• Preserves more head-hair and facial-hair detail in Ultra quality while suppressing neutral and bright background spill on soft edges.
• Keeps microphone capture active so Discord and other Pulse/PipeWire clients do not retain multi-second latency after opening the virtual mic.
• Uses one bounded OpenCV 4 owner and validates packaged dependencies before artifact upload.
• Keeps runtime installers out of immutable package environments and removes pip from Snap.
• Removes GTK image baseline warnings and harmonizes runtime log prefixes.

Recent quality updates:

• v1.3.0 adds a device-resident NVIDIA video path, stronger blur controls, safe camera and microphone power saving, corrected Apple Silicon camera selection, and cleaner sunlit replacement edges.
• v1.2.3 stabilizes Quality and Ultra mattes in strongly backlit scenes without changing displayed camera colors.
• v1.2.2 derives one shared binocular camera target, preserves natural iris spacing, and reduces coordinated eye-tracking latency.
• v1.2.1 makes moderate eye contact correction visible at the default intensity, preserves frame alpha, and includes corrected macOS OBS output.
• v1.2.0 adds DeepFilterNet3 noise removal, lower background CPU use, a native StatusNotifierItem tray, verified model storage, and configurable Linux virtual-camera output.
• v1.1.13 adds Center Face and Stable Background Auto Frame modes and fixes minimum-zoom tracking.
• v1.1.12 fixes OBS startup reliability, phone webcam fallback behavior, audio filtering dependency installs, and packaged meeting runtime support.
• v1.1.11 fixes white preview and missing-effects cases in OBS and meeting apps when cameras expose raw video modes instead of MJPEG.
• Camera startup avoids stale, metadata-only, and virtual-loopback source nodes after reboot or device-order changes.
• Source, Debian, RPM, and amd64 Snap installs include the corrected CUDA runtime path for NVIDIA systems.
• v1.1.10 improves live background replacement edges around hair, shoulders, raised hands, and finger gaps.
• Compute selection lets users choose Auto, GPU Focused, or CPU Focused behavior. GPU Focused selects the DocZeus/CUDA path when available, while CPU Focused keeps users on CPU modes when preferred.
• The arm64 Snap build stays portable and CPU-safe until Linux arm64 GPU wheels are available from upstream providers.
