Same root cause as IsChatBox — SourceType binding fails on WebcamSceneConfig,
WPF defaults Visibility to Visible without calling the converter.
Added virtual bool IsCountdown on SceneElement, override in Source.
Swapped binding to BoolToVis. Removed dead SourceTypeToVisibility converters.
- Source.ShowDesktop bool persisted in DB (schema migration + LayoutStore)
- ClearBackdropCaptureAsync clears CaptureKey + VideoImageSource for static fallback
- Top bar: red/green/pulsing status light, avatar via BitmapImage, Log In button
- ShowStartStream now requires IsConnected
- RunMockChatPreviewAsync: simple async loop, ChatPreviewEnabled property on Source
- EnsureDefaultBackdrop called on every scene switch, seeds all 5 scenes
- SeedEndingBackdrop replaces existing, SeedChatBackdrop added
- SceneCatalog: Chat scene display name corrected (layer = 'YouTube Chat')
- Left panel spacing consistency, context menu reordered
- Border animation rendering via code-behind Storyboard approach
- 3 new backdrop assets (ending-backdrop.jpg, chat-backdrop.jpg, live-backdrop.jpg)
- Build 0 warnings, 178 tests passing
- Elements panel config UI for ChatBox source (font size slider,
font/member/super-chat/background color inputs, max messages slider,
timestamp/badge toggles)
- Schema migration: 8 new ChatBox columns on Source table (ChatFontSize,
ChatFontColor, ChatBackgroundColor, ChatMaxMessages, ChatShowTimestamps,
ChatShowBadges, ChatMemberColor, ChatSuperChatColor)
- Load/save: Source SELECT and INSERT now include all ChatBox fields
- IsElementsPanelEmpty excludes ChatBox so hint doesn't cover config
- ChatBoxRenderer.cs created: WPF FormattedText + RenderTargetBitmap
renderer for on-stream chat overlay
- Slider bindings set to TwoWay for live propagation
- Assets/llamacasty-icon.png: new brand llama figure (no text)
- Assets/llamacasty-icon.ico: converted from PNG for executable
- Assets/llamacasty-logo.jpg: full logo with text
- ytLive.csproj: updated ApplicationIcon and Resource references
- All XAML windows: updated Icon references to new file
- YouTubeStreamService: added GetBroadcastLiveChatIdAsync to fetch liveChatId from broadcast contentDetails
- YouTubeChatService.Poll(): parse snippet.type to handle textMessageEvent, superChatEvent, newSponsorEvent
- MainViewModel: wire _youtubeChat.Start(liveChatId) in PrepareAndStartLiveAsync after broadcast creation
- MainViewModel: wire _youtubeChat.Stop() in StopStream before encoder stop
- MainViewModel: wire _youtubeChat.Dispose() in Shutdown
- MainWindow.xaml: updated chat DataTemplate with member badge (⭐), Super Chat highlight (💰 + gold border), timestamps (HH:mm)
- MainWindow.xaml.cs: auto-scroll ChatListBox on new messages via CollectionChanged
- Chat lifecycle is non-fatal: failures log and the stream continues without on-panel chat
1. Error text shows in red inside the desktop audio meter bar (scrollable)
when TRAX load or playback fails — user gets feedback, not just a
silent red dot.
2. LoadTrax no longer nulls _music on error — the track path is retained
so the user sees what failed and can retry.
3. OnTraxPlaybackEnded now receives the NAudio exception and surfaces it.
4. TRAX dot is green (playing) or gray (idle/no track) — no more yellow
or red states.

All three element sections (webcam border, countdown, web URI) now use
consistent [✕][✓] button order. Green check buttons enabled with click
handlers that save current values as snapshot baseline — revert undoes
to last accepted state, not initial selection.
Countdown section buttons were swapped (had [✓][✕], now [✕][✓]).
Webcam and web sections already had correct visual order.
1e of 7-issue polish batch. 207 tests, 0 warnings.
The web source section's visibility was bound to SelectedElement.Type
via a converter, but WebcamSceneConfig has no Type property — the WPF
binding path didn't resolve correctly and the section leaked through.
Added IsWebSource virtual property to SceneElement (mirrors existing
IsWebcam pattern), overridden in Source to return
Type == SourceType.WebSource. Section visibility now binds directly to
SelectedElement.IsWebSource via BoolToVis.
1c of 7-issue polish batch. 207 tests, 0 warnings.
Merged the URI TextBox and check/revert buttons into one DockPanel.
TextBox fills remaining space, buttons dock right (✓ rightmost, ✕ left).
No more line-wrapping in the web source config.
1b of 7-issue polish batch. 207 tests, 0 warnings.
The scrollbar lives inside the ScrollViewer, not the StackPanel
(ElementsPanel). Window_PreviewMouseLeftButtonDown was checking
IsDescendantOf against ElementsPanel, so scrollbar clicks fell through
and nulled SelectedElement. Now checks ElementsScrollViewer instead.
1a of 7-issue polish batch. 207 tests, 0 warnings.
- Elements scrollbar no longer deselects element on click (check ScrollViewer, not StackPanel)
- Web source: URI + check/revert buttons merged into single DockPanel row, consistent order (✓ rightmost)
- Countdown timer moved from Elements panel to inline in source list row, range clamped to 1-30 min
- Volume slider click-to-position restored: e.Handled prevents IncreaseLarge from overriding position, Thumb drag still works
- Desktop audio meter: asymmetric smoothing (attack 0.2, decay 0.08) for faster response to silence
- 207 tests passing, 0 warnings
1. About box bg → #0A0C1A (matches icon bg)
2. Elements panel collapses when no element selected / scene changes
3. OpacityChip moved from preview overlay into Elements panel
4. Color picker fix: cast to SceneElement not Source (WebcamSceneConfig was silently blocked)
5. Red left accent bar on selected items in Scene/Source lists
6. ✓ character replaced with Path checkmark icon in Elements panel
7. Removed ToolTip='Applied' from green check buttons
8. Created bugs.md with first entry (iTunes audio on mic meter)
9. Full logo in README + About box uses ytLlive-logo.png
- Removed llama-logo.ico, llama-logo.png, llama-logo-icon.png
- Added tyllive-icon.png (340x318, app icon for all windows + About overlay)
- Added tyllive-icon.ico (multi-size 16/32/48/256, Windows app icon)
- Updated ytLlive-logo.png to new 524x220 branded version with tagline
- Updated ytLive.csproj + all 6 XAML window references
- TRAX: LocalGain now applies 0.2× factor so music is quieter relative to desktop audio slider
- TRAX tooltip: switched to ToolTipService with Placement=Top to fix z-order in Viewbox overlay
- Mic meter: MeterLevel multiplied by 1.2× before clamping for ~20% higher visual readout
- Volume sliders: click anywhere on track to jump thumb to that position before dragging
- Backdrop: Image Visibility now binds to BackdropVisible; compositor checks IsVisible before blit
- Renamed 'Backdrop' to 'Game Capture' in EnsureBackdrop + test assertions
IFfmpegLocator seam that resolves ffmpeg.exe (PATH -> cache -> pinned download),
plus the licensing compliance that makes a paid GA product defensible.
NOTE FOR USERS: this change shows NO difference in the app's behavior except a
new top-bar "About" button (opens THIRD-PARTY-NOTICES.txt). It is scaffolding
for the encoder/streaming work.
- Services/Encoder/: IFfmpegLocator + FfmpegLocator. Pin is BtbN lgpl-shared
autobuild-2026-08-09-13-03 (NOT gyan.dev/GPL or static: LGPLv2.1 §6 static
relink material avoided by dynamic linking); extracts ffmpeg.exe + libav*.dll
via a staging dir so a crash never leaves a partial cache
- THIRD-PARTY-NOTICES.txt: LGPL/BSD/MIT notices + source offer, copied to the
build output, surfaced by the About button; v1 gate = bundle full license
texts (TASK 4 requirement 9)
- ai.md "Licensing - do not violate" guardrails (never GPL/nonfree/static/latest-
tag, never link FFmpeg in, never drop notices); TASKS.md + Services/index.md
updated
- Tests: FfmpegLocatorTests - hermetic decision-ladder integration test + shared-
build DLL extraction + edge cases; docs updated (78 tests passing, 0 warnings)
- Meter is a READ-ONLY realtime level display: fill = Math.Min(1, AudioLevel * MicVolume) (AudioLevel = live input from the future mixer, 0 with no input; MicVolume is gain on ambient noise). While the slider is dragged the bar previews the slider position (PreviewMouseLeftButtonDown/Up + LostMouseCapture -> SetVolumeAdjusting); on release it returns to the live level (bounces to 0 with no input). Clicking the meter does nothing.
- MicVolume drives MicMuted (read-only, muted <=> volume 0): sliding to 0 flips the speaker to the red slashed mute icon, sliding up from 0 clears it; speaker button runs volume to 0 or restores the prior level (_volumeBeforeMute, default 0.8) and flashes the meter to the restored position for ~300ms (BeginVolumeFlash/EndVolumeFlash DispatcherTimer, cancelled if the slider is grabbed).
- MIC label opens MicPickerDialog (WinRT audio-capture device enumeration, mirrors camera picker, no new packages); the chosen voice source name shows left-justified INSIDE the meter bar (fill at 75% opacity so text + ruler markings show through).
- New files: Services/IMicrophoneEnumerator, MicrophoneDeviceInfo, WinRtMicrophoneEnumerator; ViewModels/MicPickerViewModel; MicPickerDialog.
- Docs updated (ai.md, TASKS.md, Services/index.md, ViewModels/index.md); build 0 warnings, 65 tests passing
