🎯 Spout2OverlayHUD is a Windows application that displays a Spout2 sender signal as a HUD overlay, with direct access to OpenGL textures. Perfect for integrating OBS scenes and sources directly on your screen!
✅ Low latency: The signal is rendered as an OpenGL texture with minimal performance impact.
✅ Clickthrough window: Does not interfere with user input.
✅ Smooth Mode (new in 1.0): Refreshes at twice the monitor rate so no sender frame is skipped, even when sender and monitor refresh are not aligned. Toggleable from the tray menu.
✅ True pause: Pausing hides the overlay and idles the app (near-zero CPU/GPU) while tray menu and hotkeys stay responsive.
✅ Multi-monitor support (new in 1.0): Screen selector with real monitor names and resolutions, remembered size/position per screen, automatic fit-to-screen on first select.
✅ Global hotkeys (new in 1.0): Optional hotkeys for pause/resume and screen switching, configurable from the tray menu (none set by default).
✅ Dark tray menu (new in 1.0): Dark themed menu with rounded corners and descriptions on hover.
✅ Status tray icon (new in 1.0): Shows pause bars over the icon when paused or no sender is detected.
✅ Sender pinning (new in 1.0): Stays on the selected sender; if it closes the overlay waits for it instead of jumping to another sender. Automatic reconnection when it returns.
✅ Idle mode (new in 1.0): Drops to a low refresh rate when no sender is present to save resources.
✅ Versatile usage: Ideal for streamers with a single monitor, allowing real-time display of effects, chat, and interactive overlays (Crowd Control, Stream Stickers, Viewer Attack) directly in the game.
📺 Example usage: Use OBS to overlay webcams, browsers, monitors—the possibilities are endless! For a lighter sender without OBS, try WebStage.
