The creator couldn't add a webcam to Live (grayed app-wide) and nothing in the app explained why. Ground truth from the live DB: one Webcam identity AND one WebcamSceneConfig in the Chat scene — so the gray was the single-identity rule working, but the reason was unobservable. This slice makes the webcam a resource the app validates and locks, mirroring how OBS reserves its devices. At startup we enumerate the OS once (ValidateWebcamResourceStartupAsync, fired after LoadLayout, stored as WebcamStartupValidationTask for tests to await): - 0 webcams -> app runs on, layer inactive, no alarm - exactly 1 -> attempt CameraManager.AcquireAsync as an app-wide lock; on failure show a persistent red alert at the bottom of the Layers panel (WebcamLockAlert + Retry) that re-polls every 5s and clears itself the moment the camera locks, or on any first real frame - >=2 -> deliberately no auto-lock; camera selection belongs to the App Settings dialog (gear) — next slice CameraManager.IsRunning(deviceId) tells the pass a session already exists (started OR still starting) so loaded identity configs count as the lock and the pass never double-acquires. Test seams mirror LayoutPathOverride: CameraEnumeratorOverride / CameraFrameSourceFactoryOverride so the startup probe never touches real hardware under test. Good Dog test: WebcamStartupResourceTests x3 — single-cam locked + app runs on, zero-cams no-alarm/no-lock, lock-fails -> red alert -> Retry -> clears. Full suite 304/304, build 0 warnings, scope-check passed. Docs in-commit: TASKS Open items + ai.md Webcam section + HANDOFF rewrite. Also corrects the record: 'NVIDIA Broadcast opens the webcam exclusively' was a suspect-list claim (CameraConflictProbe reads process names only, no handles) — not restated as fact.
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.
Audio Assumption
ytLlive uses your default microphone and desktop/game output — it never hunts for a device or contends for one. It assumes your audio is already configured and working (default input and output set, not hijacked by another app). Audio issues are a Windows/device matter outside ytLlive's scope: we don't debug, detect, or try to fix them. If it doesn't sound right, fix the system's audio settings first — it's on the OS, not on us.
Run
dotnet build # Windows only — WPF
dotnet run
Version Roadmap
v1 is the finished product (creator ruling, 2026-09-01 — there are no v1.x releases).
Everything still queueing lands in v1; anything not on the feature list is on the closed
"Out of product — permanently" list in TASKS.md — read that page before asking for a feature.
What v1 ships: the five-scene director's control surface, webcam + screen capture, media + web + text sources, chat on-stream, the social bar, mic/desktop audio with auto-duck and TRAX, local recording, variable quality tiers with auto step-down, one-click go-live + scheduling, stream resilience (auto-reconnect inside YouTube's grace, one-click back on air), built-in monetization awareness (reward capture, session reports, YPP journey tracker), Alerts — all free and ungated; the subscription only removes the branding flash.
