TASK 49 is retired (creator ruling): YouTube owns chat moderation. Its blocked-words filter and
hold-for-review run upstream of `liveChatMessages.list` — held messages are never returned
(https://stackoverflow.com/questions/74511524/) — so a second local list would duplicate a switch
the creator already owns, with a second set of false positives and a second support surface.
What we actually owed the platform, and had wrong:
- The parser added every item to the overlay. A deleted message arrives as a `tombstone` carrying
no text at all ("it has since been deleted … only liveChatId, type and publishedAt are present" —
https://developers.google.com/youtube/data/live/reference/rest/v3/liveChatMessages), so every
deletion rendered as a BLANK chat row. `hasDisplayContent:false` messages and chat-mode events
did the same.
- Deletion events (`messageDeletedEvent`/`messageRetractedEvent`/`userBannedEvent`) are documented
but have not been delivered to clients for years (https://stackoverflow.com/questions/44346893/),
so nothing is built on them; they are skipped if they ever arrive.
- Found while testing: Super Chat read `displayString`, but YouTube's field is `amountDisplayString`
— every amount silently fell back to a recomposed string, which mangles non-dollar locales. The
model's own comment said this was the reason the field exists.
Test: `ChatModerationParseTests` — tombstone, no-display-content, chat-mode events all produce no
row; a real Super Chat still parses its pre-rendered amount (constraint 4: reward fields are never
reinterpreted).
Docs: TASK 49 marked retired with the citations, the rule recorded in decisions.md, HANDOFF updated.
verify.sh: 550 passed, 0 failed, 0 warnings.
TASK 64 slice F — the two things left after the feature worked by hand.
- App Settings → **Video clips → Auto Green/Blue Screen** (off by default). When on, a
high-confidence detected screen is keyed as soon as the clip is added; the panel says
"Removed automatically" so an automatic change is never silent. Medium confidence still
asks, low says nothing — a wrong automatic key eats the picture.
- **A clip is a clip:** the alert box's own replacement clip keys through the same settings
block (one alert box per layout, so its settings are the ones the next alert uses), and
choosing an alert clip runs the same detector. The Green/Blue Screen panel now appears for
a video layer *or* an alert box with a custom clip (`Source.ShowsChromaKey`).
- Spill ships as the creator-facing **Fringe** switch; nothing further to tune behind it.
Test: `ChromaKeyApplyTests` gains the auto-apply case (no click, still explicit in the panel)
and an alert-clip case (its pipe asks ffmpeg for colorkey+despill with the blue screen type).
Docs: TASK 64 complete in TASKS.md, known limits recorded in the task file, HANDOFF rewritten.
verify.sh: 546 passed, 0 failed, 0 warnings.
TASK 64 slices D and E: the feature is usable end to end.
- Add a video file → one frame is probed (new `IChromaProbe`/`FfmpegChromaProbe`, one ffmpeg
pass at 160x90, off the UI thread) and the layer gets an offer: "Looks like a green screen —
Remove it", with the measured colour as a swatch.
- Accepting it turns the offer into settings (Amount / Softness / Fringe) that reach ffmpeg as
`colorkey` + `despill` + `format=bgra`, so the key is computed in the pipe and both consumers
(the shared preview bitmap and the compositor's frame) carry the same alpha.
- Media sessions are now keyed by **path + look** (`MainViewModel.MediaSessionKey`), so two
layers with the same settings still share one decoder, and changing the look releases the old
session and starts the new one. Removal, load reconciliation, loop and audio settings all move
to the same key.
- Settings persist on the `Source` row (six ALTER TABLE guards + SELECT/INSERT), so a keyed layer
comes back keyed.
- Panel section is plain creator words: Green/Blue Screen, Amount, Softness, Fringe.
Test: `ChromaKeyApplyTests` — the pipe asks ffmpeg to key (and does not when off); a green-screen
clip is offered, accepting it starts a keyed session, the layer's resolver then reads that session
rather than the old one; the setting survives a save.
Docs: TASK 64 D/E ticked with slice F (auto-apply setting + alert clips) left open; frame-pipeline
records the decode-option design; HANDOFF rewritten. verify.sh: 544 passed, 0 failed, 0 warnings.
TASK 64 units B and C — the two pure halves, no wiring yet.
- `Services/ChromaKeyDetector.cs`: samples the frame's outer ring (the screen is at the
edges, the subject in the middle), reports Green/Blue/None plus the colour actually shot
and a confidence. Confidence is coverage × hue tightness, which is what keeps a lawn or
a football pitch from being offered as a keyable screen. Letterbox bars are excluded from
the denominator rather than counted against the screen. Never decides anything: an offer
is the creator's to accept.
- `Services/VideoFilterChain.cs`: options → `-vf` (scale → colorkey → despill → format=bgra)
plus a `Signature` so two layers keyed identically can share one decoder. Numbers clamp and
an unparseable colour falls back to the app default, so ffmpeg is never handed a filter it
rejects at spawn.
- Keying is done by the bundled ffmpeg, not by us: verified against the shipped binary that
`colorkey=…,format=bgra` emits straight-alpha BGRA (alpha 0 on keyed pixels), which is what
the compositor already blends. No per-pixel loop lands in the 16.67 ms render budget.
Test: `ChromaKeyDetectorTests` — green, blue, letterboxed, lawn (must say None), mixed scene,
dark frame, plus the chain strings and signature sharing.
Docs: TASK 64 queued in TASKS.md with its slice table; the decisions.md chroma-key reversal
recorded as a reversal (it was buried for webcam background removal, not for supplied clips).
A video file was picture-only: the decode pipe passed `-an`, so a starting-soon
or BRB clip with music played silent everywhere. Adds sound to every clip and
collapses the two decoders into one.
- `Services/VideoClipPipe.cs`: the shared pipe behind `MediaVideoSource` (TASK 21)
and `AlertClipDecoder` (TASK 47) — video (`rawvideo bgra`, scaled) + audio
(`f32le -ac 2 -ar 48000`, 50 ms chunks, byte-carry across reads), both paced to
real time, loop restarts both so picture and sound stay together. Alert
behaviour is unchanged.
- `MediaVideoSourceManager` applies the layer's Level/Mute per session and raises
`AudioAvailable`; `MainViewModel` feeds it to the new
`AudioMixer.EnqueueDesktopMediaAudio`, which joins the DESKTOP/GAME ring so the
desktop fader and the mic auto-ducker apply exactly as they do for game audio
and TRAX (creator ruling 2026-11-05: audio joins the group).
- Per-layer `MediaMuted` + existing `MediaVolume` surfaced as Mute/Level in the
properties panel; `MediaMuted` persisted (ALTER TABLE guard + SELECT/INSERT).
- Level/mute are per SESSION because one decoder is shared per file path — the
last layer touched wins; one decoder per layer would play the file twice.
Test: `MediaSourceAudioTests` — the pipe emits 50 ms chunks at 48k stereo, the
manager scales by level and drops when muted, and a media layer's sound moves the
desktop meter. Alert/decode suites unchanged and green.
Docs: task-21 closed on item 10, the "silent soundtrack" facts corrected in
frame-pipeline/output/overlays, HANDOFF rewritten. verify.sh green (529 passed;
the two documented pre-existing failures only).
TASK 21's picker slice: the decoder, manager, pacing and loop mechanism were
already shipped but nothing ever acquired a session, so a media Source rendered
nothing. Adds "Video File" to the (+) menu (video-filtered OpenFileDialog),
one decode session per distinct path with a HasSession guard, release when the
last scene reference goes, and a post-load reconcile. Loop is a manager-level
per-path answer ("any live reference loops") applied before StartAsync and
updated live via SetLooping. Properties panel shows the file with Change… and
Loop. Volume stays unwired: media audio rides the desktop loopback, TRAX-style.
Reference: OBS's media source (file → decode → composite into the scene) is the
established answer for this feature; the lifecycle shape mirrors this repo's
WebView2/ScreenCapture registration rather than inventing a new one.
Test: ytLive.Tests/MediaSourceAcquisitionTests.cs — add starts one decoder and
frames reach the layer, loop flip reaches the decoder, remove stops it.
Docs: task-21 closed, TASKS row + Day-4 row + stale 3·17 row corrected,
frame-pipeline acquisition note, HANDOFF rewritten. verify.sh green.
The four llamacasty-* files were source exports, not assets: shipped art is
embedded via <Resource> in ytLive.csproj and read through pack: URIs, and the
Store tiles derive from Assets/llamacasty-logo.jpg. None of the four appears in
the csproj, any XAML Source/Icon, or a script, so they were dead weight that
kept resurfacing as untracked noise.
MyMistakes.md gains the recipe (csproj list + grep = 30-second verdict) so a
loose file in Assets/ is never re-litigated; HANDOFF drops the stale note.
Put size and color on one row, place emphasis labels before their toggles, and split the remaining font families into handwriting, symbols, and international groups while omitting legacy dingbat fonts. Text-layer properties follow the existing hierarchical layout and palette conventions.
Use category-filtered font and selected-item dropdowns, separate horizontal and vertical alignment, and reuse the border-color palette templates for text color. Persist vertical alignment additively. Follow the established static text-source pattern: https://obsproject.com/kb/text-sources
Raster static text on UI-thread changes and reuse the same transparent BGRA frame in preview and all compositor paths. Cache text frame identity in the frame-pump signature and invalidate static bakes on edits. Follow OBS text-source conventions: https://obsproject.com/kb/text-sources
TextOverlay layers now have a multiline editor, Windows font and size controls, color/emphasis/alignment settings, and a visible draggable preview. Text sources follow OBS's static text-source conventions: https://obsproject.com/kb/text-sources
Add additive defaults and round-trip tests for per-layer text content and formatting. Model the static text source after OBS text-source conventions: https://obsproject.com/kb/text-sources
The frame pump now submits crop-sized BGRA frames; FFmpeg scales them to final tier dimensions. Bundled scaler benchmark: 300 608x1080 to 1080x1920 frames in 0.435s (scaler-only).

Add independent AppLog message types and explicit Class 1/2 severity. Wrap and color log rows, pin Class 1 above Class 2, and let acknowledgement return entries to the current-launch timeline without changing file format or rotation.

Add Live Chat and Logs tabs to the non-edit left panel. Expose a bounded process-local AppLog feed so the newest messages appear first without importing earlier startup.log contents or changing file logging.

Model the AlertBox and standalone ticker with shared settings; scene tickers render the in-memory active and queued events without saving history. Keep AlertBox content active-event-only.

Keep non-owner resolution choices visible but muted. Selecting one preserves the free tier and opens About; external navigation is only the explicit llamacasty.com link. Ref: https://streamlabs.com/desktop
The earlier pass checked wiring only; this is the typography sweep. Raw Foreground/FontSize
labels are gone from the elements panel:
- Opacity, Timer (minutes) and URI are headings above their control (PropertyHeader), with the
control row on the panel's 10px indent — the same shape as Border Thickness/Opacity.
- Scroll speed, scoreboard Opacity/Text size and their value readouts are PropertyFieldLabel.
- The drag hint and the scoreboard sign-in note are PropertyHint.
- Simulate (dev) keeps its orange, gains the field-label typography.
- Edge, Text colour and Background were PropertySubHeader/SubHeader: ONE heading rank now, so
PropertySubHeader and the legacy SubHeader are deleted from Themes/Controls.xaml.
- DeveloperPanel — the last panel with raw typography and an unstyled CheckBox — now uses the
same styles, and PropertiesStyleTests accepts PropertyPillCheck (the guard went stale when
every check box became a pill switch). 18 tests pass; Release 0 warnings.
Their rank is carried by size and colour, not by an indent — so Video, Sound byte and Ticker all
line up on the left edge exactly like each other, and only the controls under them tab in.
The brand exemption for the universal blur put a BrandLogoOverlay above the blur host while the
canvas ItemsControl kept drawing the same element, so two logos sat on top of each other.
- The canvas presenter for a brand logo is collapsed: BrandLogoOverlay is the only render, and it
now carries the element's Opacity so the canvas copy is not missed.
- Hit-testing follows the eye: a click inside the logo's bounds selects the logo, because it is the
topmost layer in the compositor too. Without that you saw the logo on top and grabbed the webcam
underneath it.
- SelectedLayerPreviewHitTestingTests updated to the new contract (collapsed presenter, logo wins
its bounds, list selection still works). 3 tests pass; Release 0 warnings.
The preview draws two background images — BackgroundImage and, above it, ActiveBackgroundImage
(the static art) — while the mini-pane reads the scene snapshot. The default-restore path only
called UpdateBackgroundImage, so the thumbnails updated and the preview did not.
It now calls UpdateActiveBackground as well.
Also adds the generic cure behind the Background bug: OnSelectedElementPropertyChanged invalidates
the scene bake for ANY property change. A static layer's pixels are cached by element identity, so
a property edit without invalidation repaints nothing and the control looks dead — the failure was
never specific to UseDefaultBackground, only first noticed there.
Background + thumbnail tests pass (21); Release 0 warnings.
Browse… writes the chosen picture into BOTH CustomBackgroundPath and AssetId, and the default
stamp bails when AssetId is already set. So flipping "Use default background" back on changed a
bool while the preview kept showing the custom image — it looked like the switch did nothing.
Turning the default on now clears the custom pointer and the asset, re-runs
StampDefaultBackgroundAsset for the scene's shipped art, and only then invalidates the bake,
updates the preview and refreshes thumbnails.
BackgroundTests pass (17); Release 0 warnings.
Review findings from a screenshot of the Stream Alerts panel, each addressed:
- "Reset to built-in" and "Browse…" were YtButton-derived (white, semi-bold, 13px), so a reset
action outranked the section header. Property-panel actions now use PropertyButton: bordered,
11px, normal weight, OnSurface text.
- Explanation text and field labels were the same muted blue-gray. PropertyHint is now
OnSurfaceDisabled, one clear step below a label.
- Groups inside a category ran together. PropertyDivider (1px OutlineVariant) separates Video,
Sound byte and Message ticker.
- The disabled loop switch was near-invisible. Disabled now keeps the label at OnSurfaceVariant
and dims the whole control to 0.55 — readable, obviously inactive.
- Switch "on" was full-strength accent, shouting about static state. The track now sits at 0.6
opacity when on, which also stops it competing with the slider's accent fill.
No new palette entries: every change uses an existing token, so DESIGN.md stays the one colour
source. Release 0 warnings; token and typography tests pass.
Creator directive 2026-11-01: the properties panels had 14 hand-rolled heading styles, 37
hand-rolled labels, four literal grey hex values, and 14 square checkboxes.
- PropertyHeader / PropertySubHeader / PropertyFieldLabel / PropertyHint in Themes/Controls.xaml
now carry the whole hierarchy: category bright and 11px, labels and hints dim, size and weight
doing the level. Colour groups the panel — bright for what you edit, dim for its labels and
help — and no new palette entry was needed; DESIGN.md stays the only colour source.
- Every checkbox in the panel is a pill switch (PropertyPillCheck, 32x16 animated thumb).
IsChecked semantics unchanged, so no binding moved.
- Literal #888/#666/#555 became OnSurfaceVariant / OnSurfaceDisabled.
- 13 headings, 2 sub-headers and 31 in-row labels now reference a style instead of repeating
colour + size + alignment inline.
Controls audited for backing: every Button/Slider/ComboBox/CheckBox/ToggleButton/TextBox in the
panel has a Command or Click, a Value binding, an ItemsSource or Selected*, IsChecked, or Text —
no dead controls. Release 0 warnings; typography and token tests pass.
New `youTubeTrainingVideos.md`: the feature list worth filming, split into "ready now" and
"after the surge lands" so nothing gets filmed before it exists, plus the format decisions
settled on 2026-11-01.
Format: 16:9 long-form is the library (search intent, walkthroughs, conversion); vertical Shorts
are trailers cut from the same pass. A 16:9 video cannot be a Short, so it is a per-video choice.
TikTok is a mirror of the verticals, never a strategy.
The numbers behind it: Shorts need 1,000 subs + 10M views in 90 days for YPP versus 4,000 watch
hours in a year; Shorts RPM is $0.02-0.08 per 1,000 against $3-8 for tutorials; and one $79 sale
nets ~$55.30, which is what 700k-2M Shorts views pay. Shorts are an install engine, not revenue.
Film first: privacy blur, auto-ducking, webcam blur.
Creator ruling 2026-11-01. One SKU, one price, Steam does the selling.
- Pro is a one-time Steam DLC on the free app: $79 introductory, $99 on a stated date, announced
where the price is shown and actually raised.
- The subscription is retired. The reasoning is in decisions.md: no service behind a monthly fee
(no servers, no cloud, no content), ~1-3 subscribers per 1,000 installs against 5-8% churn, and
it carried the most expensive code in the product.
- Polar goes dormant. Its customer-portal design is recorded, not built. The "freemium on Steam,
convert on Polar, Valve gets nothing" proposal is rejected: in-app purchases must use the Steam
Wallet, so it risks the listing to save ~$24 a sale.
- Entitlement collapses to `steamDlcOwned`. No lease, no key, no portal, no device limit; the
greyed tier opens the Steam store overlay, so every purchase stays inside Valve's own surface.
- The site publishes the model and links the store page. It takes no payment and hosts no binaries.
- The $400 lifetime died with the subscription it anchored. Founding 200 died with the coupons and
passes it needed.
Costs: $115 fixed year one; $79 nets $55.30 after Steam, so three sales cover the year.
