The widget page paints html/body opaque, so CapturePreviewAsync output had
zero alpha-0 margins — every take since bccdb48 built the crop on 'the
capture is transparent' and never verified it. WebView2 spec is explicit:
'WebView will always honor a webpage's background content' and
DefaultBackgroundColor only shows through pages with no background style
(MicrosoftEdge/WebView2Feedback specs/BackgroundColor.md). The late
ExecuteScriptAsync injection (NavStarting/NavCompleted) ran after page CSS
and lost the fight.
Fix via CoreWebView2.AddScriptToExecuteOnDocumentCreatedAsync — the
documented pre-parse hook ('before the HTML document has been parsed and
before any other script included by the HTML document is run'), the same
mechanism OBS user.css uses. Nav handlers kept as post-load re-assertion.
Restores the take-23/24 stride-correct crop path (my take-25 removal was
wrong — it regressed the bounding box into a solid black box).
Adds one-shot diagnostics: raw capture PNG -> %TEMP%/ytLive-web-<id>.png
plus alpha min/max/mean/%zero and FindContentBounds result in startup.log,
so the next run proves the capture is transparent instead of guessing.
Build 0 warnings, 289/289 tests pass. MyMistakes.md records the full chain.
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.
