gramps 9d04aea55b UNIT 0 reading: the camera was never the problem, so Unit 1 is the wrong lever
Take ty-20261005-1201-556-0001.mp4 (75.3s) plus its log settle it. The
C920 delivers 30.0/s with ZERO gaps over 50ms and its own device stamps
agree - camera, USB and driver are clean. The pump managed 34 composites per
5s at ~141ms each, and the file holds 6.8 distinct webcam images per second
at 88.7% duplicates with no arrival hitch whatsoever. The judder is us
holding one face for 140ms and padding the rest of a 60fps container, which
is precisely what a lipreader experiences as "cutting out".

So 720p is a SHARPNESS win, not a smoothness win: it triples the bytes the
compositor stretches per render on a path already 4.4x over budget. The
exclusive camera lock stays agreed and stays queued, but it moves after the
compositor work or it makes the judder measurably worse.

The number still unexplained: the 10:01 take hit 25.6 images/s and this one
6.8, with the same scene shape (full-render split=0 elements=6 dynamic=5)
and the same 640x480 camera - composites went 29-34ms to 143-155ms between
sessions and nothing logged says why. There is no per-element composite
breakdown and no scene dump at pump start, so the next unit is measurement,
not a fix. Recorded the pump-counter overcount (13/s vs 6.8/s: one 141ms
composite lets ~4 camera frames arrive, and the counter stamps the first
epoch the resolver sees, not the frame actually drawn) so it is not
re-derived as a bug later.

ytLlive

LlamaCasty — livestream smarter

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 paid tier only removes the branding flash.

Structure

Path Role
Models/ Scene, Source, WebcamSceneConfig, SceneElement, SceneCatalog, QualityOption, StreamConfig/Health, chat, Socials, BroadcastMetadata, Music, MicStatus
ViewModels/ MainViewModel (partial classes per area) + dialogs: GoLive, CameraPicker, MicPicker, HotkeyConfig, Socials, LiveBroadcastForm
Services/ YouTube (OAuth, streams/broadcasts, chat polling), LayoutStore (SQLite), capture (camera/screen-capture/media-file via FFmpeg), SceneCompositor + FramePump, FFmpeg encoder + RTMP, audio pipeline (WASAPI loopback + mic, mixer, filters, ducker, limiter, TRAX), SocialValidator, notifications, hotkeys, SceneGraph, ChatOverlayLayer
Helpers/ ViewModelBase, RelayCommand, ImageCache, AppLog, TokenStore (DPAPI), OAuthCredentials, converters
Themes/ Controls.xaml — the dark-theme control styles, merged once in App.xaml
MainWindow.xaml Dark-theme control surface: thumbnails + central preview, two-state left panel (layers/properties ↔ live chat), top bar, footer
Distribution.md GA-time plan: signing, installer, EULA, hardening — executed as TASK 36

Docs (memory map)

schema.md defines the conventions; ai.md is the AI/session guide; TASKS.md is the task queue. Each code directory carries an index.md.
