ty-1723/1726 device takes showed accelerated playback + audio tail cut-off:
a render overrun (~35ms vs the 16.6ms slot) SKIPPED the missed slots (slice 10's
freshness choice), so a 60fps-authoring pump wrote one frame per 35ms into a
60fps container — 1723: 697 frames/11.62s vs 11.84s audio; 1726: 163/2.72s vs
2.93s, video ending 0.21-0.24s early.
OBS never leaves a wall-time hole: the video thread emits one frame per tick and
a lagging producer DUPLICATES the newest frame ("lagged frames due to rendering
lag/stalls" — obs-output.c; "If the video frame queue is full, it will duplicate
the last frame" — docs.obsproject.com/backend-design). The pump's submit is now a
bounded catch-up over the missed slots (while now >= nextTick), fresh on the first,
repeated after — duration == wall, judder not fast-forward. Safe because Channel.
TryWrite never blocks (the take-9 smear was the blocking pipe-write; each emit is
nanoseconds). Burned frame index moved inside the loop: every emitted slot carries
its own +1 (also fixes the old unconditional pre-gate bump that gapped the judge
sequence on non-submitting fast-render iterations).
Good Dog test: Pump_Overrun_Renders_EmitsEverySlot_NotSkipped (60fps, 35ms render
cost, asserts >=0.65 of the wall slots emitted). 294/294 green, 0 warnings.
No push — web/A/V work is commit-local until greenlight.
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.

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.
