Software compositor that renders a scene into the encoder's master VideoFrame, mirroring the XAML preview minus editing chrome: backdrop -> background -> elements (UniformToFill cover-crop, round clip, mirror, opacity, border) -> branding flash. NOTE FOR USERS: this change shows NO difference in the app's UI — it is pure backend scaffolding laying the groundwork for live video capture/streaming. The preview you see is unchanged. - Services/Compositor/: SceneCompositor (Render(scene, frameFor resolver, flashFrame, CompositorOptions)), CompositorOptions (source rect + output size; 16:9 full master, vertical 607x1080 -> 1080x1920), StretchMath (pure UniformToFill + bilinear), StaticPixelCache (asset bytes -> BGRA8 frame) - Frame sources injected via Func<SceneElement, VideoFrame?> resolver, so the compositor is pure, WPF-free, and hermetic to test (D3D11 upgrade behind the same seam later) - SceneElement.TryGetBorderColor public (shared hex parse), stale MainViewModel comment fixed, pre-existing CS1998 in YouTubeAuthServiceTests cleaned up - Tests: SceneCompositorTests integration (full scene + vertical tier + flash) + StretchMath units, docs updated (72 tests passing, 0 warnings)
ytLlive
A creator-proof live-streaming and recording app for YouTube — native Windows (C# / WPF / .NET 8).

Design Principle
This software is so intuitive that even the most right-brained person can easily intuit and use it.
Every feature is measured against this. One-click go-live, sane YouTube defaults, visual scene building, and no dead ends — every action has a visible outcome.
Why ytLlive
OBS treats YouTube as an afterthought; SLOBS is Twitch-first with YouTube bolted on. ytLlive is designed and dedicated to YouTube livestreaming and recording, and to YouTube's specific quirks.
Account Assumption
ytLlive assumes you already have a YouTube creator account — connecting uses "Sign in with Google" to link that existing account. ytLlive does not create accounts. If you don't have a YouTube channel yet, set one up on YouTube first, then connect it here.
