gramps 94f015044a fix(stream): TEST-tab chat — resolve liveChatId from snippet, poll until the broadcast is live
The open creator report ('I still cannot post a chat message in the TEST tab',
feedback 'Chat polling couldn't start — Mock Chat Input is disabled') was a single
cause: the liveChatId never resolved. Two YouTube API facts:
1. The id lives in snippet.liveChatId — contentDetails has no such property
   (TASK 44 read part=contentDetails: could never resolve).
   https://developers.google.com/youtube/v3/live/docs/liveBroadcasts
2. It only exists once the broadcast is LIVE — the official sample lists
   broadcastStatus=active, and our fetch ran before the frame pump pushed RTMP
   (enableAutoStart flips ready→live). A ready-state list legitimately returns
   no id.
   https://github.com/youtube/api-samples/blob/master/java/src/main/java/com/google/api/services/samples/youtube/cmdline/live/GetLiveChatId.java

Fix: GetBroadcastLiveChatIdAsync reads part=snippet and polls with a bounded
retry (10x/2s); PrepareAndStartLiveAsync starts the frame pump FIRST, then
resolves the id. Chat stays non-fatal. Docs ai.md/TASKS.md/HANDOFF.md +
MyMistakes recipe updated same commit. TASK 44.

Good Dog: ONE integration test (GetBroadcastLiveChatIdAsync_Polls_Snippet_...
) drives a broadcast that gains its id mid-retry and asserts every request used
part=snippet. Gate: clean build 0 warnings, vstest 318/318.

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 one-time license 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.
