The last resilience slice. When a drop ends the broadcast, YouTube cannot resume it, so the only way
back is a new one — and that is what the app now offers, in one click.
- `Services/BroadcastTitle.cs` — the resume marker is applied to the title the show was using, and any
existing marker is REPLACED rather than stacked ("Show (resumed)" → "Show (resumed 2)"), with the base
truncated so the whole title fits YouTube's 100-character limit. Otherwise a channel grows two
identically named videos and the creator has to explain it.
- `MainViewModel.BackOnAirCommand` — reuses the ordinary go-live path with the saved details and the
cached stream: new broadcast, new VOD, no dialog. It appears only after a drop ended the session and
the ordinary start button steps aside, so there is exactly one way forward.
- The running line goes red OFF AIR (not amber) in that state; the button reads "● Back on air".
Tests: `BackOnAirTests` — first re-air marks the title, a second drop counts instead of stacking, the
100-character limit holds, an empty title still works, and the post-drop state exposes exactly one
start affordance. FAST gate: 552 passed, 0 failed, 0 warnings.
TASK 32 is now complete: fragmented MP4, blip retry, poll-driven RECONNECTING, ingest pre-flight, Back
on air.
"I forgot the VPN" used to create a broadcast on YouTube that nothing ever pushed to: the app looked
live, YouTube held an empty broadcast, and the creator had to work out what happened. Prevention beats
recovery here, so go-live now asks one question first.
- `Services/IngestProbe.cs` — `IIngestProbe` + `TcpIngestProbe`: parse the RTMP URL, connect to the host
(rtmp → 1935, rtmps → 443) with a 2 s timeout. Any failure answers "not reachable"; the point is a
fast unambiguous answer, not a diagnosis.
- `MainViewModel.IngestPreflightAsync` runs **before the first API call** whenever a cached ingest URL
exists; on a first run it probes once the stream is resolved, still before any broadcast is created.
A false answer logs, tells the creator ("Nothing was created on YouTube…"), and rolls the session
back — nothing to clean up on YouTube.
- The probe is a test seam (`IngestProbeOverride`) like the camera and chroma ones.
Tests: `IngestPreflightTests` — unreachable aborts, reachable continues, URL parsing (rtmp/rtmps,
garbage), and the probe against **real sockets**: a listening port answers true, the same port closed
answers false and does so fast. FAST gate: 547 passed, 0 failed, 0 warnings.
Creator challenge (2026-11-05): "I really don't think that's going to be a constant — it's going to
depend on so many variables, some that are dark to us." Correct, so the measured-grace constant and
the countdown are dropped from the spec. YouTube's cutoff is server-side and depends on ingest health,
prior stream quality, region and load; a pinned number would be a guess wearing a timer, and it would
be wrong exactly when the creator is staring at it.
What ships instead:
- **Amber RECONNECTING** in the top bar with measured facts only: elapsed seconds and the attempt
number ("0:12 · attempt 2 of 4"). The seconds come from a stopwatch started at the drop.
- **The status poll speeds up while recovering** (30 s → 4 s) and drives the sign; it restores 30 s
when recovery ends.
- **`chatEndedEvent`** — already in the chat feed we poll and previously skipped — now raises a signal
that prompts an immediate status check. It never decides anything: `liveBroadcasts.list`
`lifeCycleStatus` stays authoritative, with `liveStreams.list` health as the push-received signal.
- At `complete`: red OFF AIR (the existing stop path) rather than a pretend-live sign.
Tests: `ChatEndedSignalTests` (the marker is not a chat row, the service raises the signal, and a
complete broadcast ends recovery with the honest message). FAST gate: 543 passed, 0 warnings.
Derived from the clock rather than a literal, so a build shipped next year does not display a stale
date. The About test asserts the rendered string, year included.
Creator: system messages are limited to two lines; the label above the message ('STEAM ID NOT
PRESENT', 'STREAM') was repeating what the row already said and pushing the stack past its budget.
AttentionAlert loses Label; rows render Text only. The licence row is now exactly:
Steam ID Limit: 30fps
Click for More Info
(60fps with a close control once owned). Rows are identified by Id internally, so nothing in the UI
depends on the removed text. Tests updated to assert position/text rather than the heading.
A dead encoder used to run the whole stop path, so a one-second blip ended the broadcast. Now a dropped
push is relaunched against the same ingest while the broadcast is still alive.
- `Services/StreamRetryPolicy.cs` — immediate, +1 s, +2 s, +3 s. Minimum waits on purpose (creator
ruling): YouTube's grace is short, so every second not pushing is grace spent.
- `Services/StreamRecovery.cs` — the loop, with the audio pipe recreated before every attempt (its
server is single-instance and unusable after the old client dies, so a naive relaunch fails on a
missing input). After a push comes up it asks the API whether the broadcast survived: "complete"
ends recovery as `BroadcastComplete` instead of showing a live sign over a dead stream; an API
hiccup counts as recovered rather than ending a healthy session.
- `FramePump.EncoderFailed` — a dead push is recoverable; a compositor fault still goes through
`Failed` and ends the session, because retrying it would loop.
- `MainViewModel.Recovery.cs` — wires the steps, reports each episode into the left panel alert stack
(one row per episode, updated in place, log range painted), and cancels on Stop.
- Alert stack polish: a rule and a gap now separate the stack from the scene layers (they read as one
list before), and the licence indicator uses the creator's wording — `STEAM ID NOT PRESENT` /
`Steam ID Limit: 30fps` / `Click for More Info`, becoming `STEAM ID PRESENT` / `60fps` with a close
control once owned.
Tests: `StreamRecoveryTests` (schedule, recover on attempt 2 with the pipe restarted each time,
complete-broadcast honesty, unknown liveness, give-up, cancel, audio-restart fault),
`FramePumpTests` now pin that process death raises `EncoderFailed` and not `Failed`.
FAST gate: 538 passed (one documented pre-existing audio failure), 0 warnings.
Creator design (2026-11-05). A stack of red rows at the top of the left panel, above both mode grids
so it shows while editing and while live, pushing the panel's content down.
- Row 1 is the **Steam licence indicator** and nothing displaces it. It reads as status, not a
warning: "Entitlement 30 fps · Maximum 60 fps", both numbers derived from QualityOptions and
HasProOutput. While higher tiers are unavailable it shows a **pin** (standing indicator, no close
control); once ownership is verified the pin becomes a **close control** and the dismissal is
persisted (`Steam.LicenceIndicatorDismissed`), permanent while ownership holds. Losing ownership
restores it as pinned — a change of state, not a preference. Click → About.
- **Event rows stack beneath, newest first**, one row per episode (an episode advancing its state
updates its own row rather than adding another). Each is dismissible. Click → the Logs tab opens
with that event's sequence range painted red (`HighlightedLogFrom/To` + `LogInRangeConverter`; two
numbers rather than a collection because the log list is virtualised and realised rows do not
re-evaluate on membership changes).
- Replaces the old red panel under the quality picker, which is removed.
- The Steam diagnostic text loses "Contact the creator or support" for a neutral
"Steam licensing is not configured in this build."
Tests: `AttentionAlertStackTests` — pinned first with the status text; owned → closable and the close
survives a reload but ownership loss restores it pinned; pinned cannot be dismissed; event rows LIFO
with in-place episode updates; clicking an event opens Logs and sets its range. AboutHub + Entitlement
tests updated for the removed panel and the new wording. FAST gate: 532 passed, 0 failed, 0 warnings.
Two follow-ups from the creator's lip-sync observation.
1. Audio still slept a fixed 50 ms per chunk — the same "sleep on top of the work" fault fixed for
video an hour ago, left in place. Every chunk's read cost was added, so a clip's audio fell
progressively behind its picture: small per chunk, unbounded over a long clip. It now uses the
same deadline pacer, so audio and video advance on the same wall clock.
2. The preview pane is NOT the compositor. "Preview looks great" proves the decode and the preview
bitmap; the recording and stream are blitted by SceneCompositor. `MediaCompositeOutputTests`
renders a keyed video layer over a background through the real compositor and asserts the two
things that matter: keyed (alpha 0) pixels let the background through, and the subject half
covers it. So "green screen removed" is now proven in the output path, not just the pane.
Also: a round-clipped video layer had no preview trigger (only webcam+Round existed), so it would
render in the output and be invisible in the pane. Same unit-circle path now covers it.
Tests: 16 scoped (pacer, real-clip rate + keying, composite output, decode pacing, alert pacing)
green. FULL SUITE NOT RUN — the machine is in use: two runs under load aborted in the WPF test host
(HWND subclass crash) and one hit the 15-minute cap. Re-run scripts/verify.sh in a quiet window.
Reported as "the default video and the green screen video are playing at a hideously slow
rate… I thought the playback timing issues were resolved?!" They were not: two independent
faults, both in the shared clip pipe.
1. QUADRATIC COPY IN THE FRAME READER. `RawVideoFrameReader` re-concatenated the whole pending
buffer on every `Feed`, and the pipe feeds it 64 KB at a time. A 1080p BGRA frame is 8 MB, so
one frame cost ~127 copies of a growing buffer — roughly half a gigabyte of memcpy per frame.
Measured on a 30 fps clip: 6 frames in 3 seconds (2 fps). The reader now fills one preallocated
frame buffer and hands that array to the VideoFrame, so a frame is copied exactly once. Pipe
reads are 256 KB. Same clip: 29 fps.
2. PACING SLEPT ON TOP OF THE WORK. A fixed 1/fps sleep after each frame adds the frame's own
cost, so 20 ms of work on a 30 fps clip yields 1/(33+20) ≈ 19 fps — measured 20.9. Pacing is
now deadline-based (`Helpers/FramePacer.cs`): wait only what is left of the frame's interval,
resync when a frame overruns instead of bursting, never sleep longer than one interval.
The alert clip shares this pipe, so it gained both fixes.
Tests: `FramePacerTests` (subtract work, no drift, late → resync, zero duration, reset);
`ChromaKeyRealClipTests.RealClip_PlaysAtItsNativeRate` (throughput floor of 15 fps on the real
30 fps clip — the old code sat at 2); the two pacing assertions now check "at most one interval"
rather than an exact sleep, which is what deadline pacing means. Full suite: 574 passed,
0 failed, clean build.
The creator's test_greenscreen_moving_subject.mp4 (1920x1080, 5s, subject moving over a
green field) is what exposed the detector's brightness ceiling and proved the key colour must
come from the measured screen.
Development-only by construction, not by convention: ytLive.csproj lists Assets as explicit
<Resource Include> entries with no Assets/** glob, so a file that is not on that list is never
compiled in, copied to output, or published. The test project links this one path into its own
Fixtures output, so the repo holds ONE copy (23 KB).
Three reports from the creator, plus two bugs the real clip exposed.
1. A video layer was INVISIBLE in the preview. The pane's per-layer Image is Collapsed by
default and switched on by a whitelist of DataTriggers; MediaSource matched none, so the clip
decoded into a bitmap that nothing displayed. Same defect the alert box hit on 2026-09-26 and
the scoreboard after it — now recorded at the top of docs/ai/ui-surface.md with a test that
asserts the bound Image is Visible (`MediaPreviewDisplayTests`).
2. Play is no longer tied to Loop: the button is always enabled (creator ruling — Loop must not
toggle Play). Loop still restarts a finished clip, which is the behaviour that was broken.
3. Geometry is now the LAST section of the properties list for every draggable element, with
opacity at the top; the web source's duplicate geometry block is gone (it now uses the shared
one, which had been sitting above the media panel).
4. The physical mouse-drag test is deleted. It injected real cursor movement, hijacked whatever
machine ran it, and failed whenever the desktop was busy. The arithmetic it covered now lives
in `Helpers/DragReorderMath.cs` — pure, and covered by `DragReorderMathTests` (threshold,
up/down moves, no-op and out-of-range). The two persistence tests were already synthetic.
5. Real-clip check (creator's `test_greenscreen_moving_subject.mp4`, 1920×1080): the detector
REJECTED it — a fully saturated green sits at value 1.0 and the detector's 0.98 brightness
ceiling threw it away. White highlights are excluded by the saturation floor, which is the
property that actually separates them, so the ceiling is gone. With it fixed, the clip is
detected as green (high confidence), and keyed through our own pipe 97.8% of pixels go
transparent. Measured: keying with the canonical #00B140 keys 0.0% of this clip — which is why
the key colour comes from the measured screen.
Tests: 567 passed, 0 failed, clean build 0 warnings. The gate's scope check flags
`Assets/Videos/test_greenscreen_moving_subject.mp4` — the creator's working copy, deliberately not
committed; the fixture lives under ytLive.Tests/Fixtures.
Reported 2026-11-05: "when I click Loop, the video doesn't play in the preview pane". Two
causes, both real:
- `VideoClipPipe.StartAsync` bailed out once it had run once (`_run != null`), so a clip that
reached EOF could never be started again — it held its last frame forever.
- Loop is only consulted at end-of-file by a LIVE decoder, so flipping it on a finished clip
did nothing at all.
Now: the pipe reports running state and is restartable after a natural end; the manager marks a
session finished (keeping its last frame) and exposes `IsRunning`/`RestartAsync`; the layer shows
`IsMediaRunning`/`IsMediaFinished`; flipping Loop on a finished clip restarts it.
UI: `▶ Play` sits to the right of the **Video File** label and is enabled only while Loop is off
(creator ruling: with Loop on the clip already runs continuously, so there is nothing to start).
The panel says "Clip finished — holding the last frame." so a frozen picture explains itself.
Also: verify.sh no longer runs physical-input tests by default. That test moves the real cursor
(SetCursorPos + mouse_event); running it mid-gate hijacks the machine someone is using, which is
exactly how it felt. Opt in with PHYSICAL_TESTS=1 when the desktop is idle; the header documents
the scoped-run command for working hours.
Test: `MediaPlaybackRestartTests` (pipe restart, finished state, Play again, Loop-on-finished).
8 scoped tests green. FULL SUITE NOT RUN — the machine was in use; run scripts/verify.sh in a
quiet window before the next milestone.
TASK 32·4. A plain MP4 keeps its index (moov) at the end, so a power cut or a killed
process left the entire recording unreadable even though every video byte was on disk.
The record block now carries
`-movflags +frag_keyframe+empty_moov+default_base_moof`: index first, a playable
fragment flushed at every keyframe, so an interrupted take plays to the last fragment.
Record block only — the FLV stream output has no index and never gets the flags.
Rename-on-stop is untouched.
Test: `Args_RecordBlock_IsFragmentedMp4_SoACrashKeepsTheFile` asserts the flags on the
record block and their absence from the streaming block.
Not yet proven on a real interrupted take (kill ffmpeg mid-recording, play the result);
the args test is by construction.
Docs: task-32 slice 4 ticked with that caveat, TASKS row, output.md record note, HANDOFF.
verify.sh: 550 passed (mouse-injection test excluded, desktop in use), 0 warnings.
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.
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).

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.
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.
Creator request: a sound-byte browse + label under Built-in video, with an option to loop the
sound while the clip plays. The video itself is always one pass to completion.
- Source gains AlertAudioPath and AlertAudioLoop, persisted (column + migration + INSERT +
SELECT + reader, the whole chain — that chain is where the blur crashed once).
- The sound byte plays through MediaPlayer on the default output device; MediaEnded re-seeks to
zero while looping, and StopClip kills it so a tail cannot bleed into the next alert.
- The clip's OWN soundtrack moved off the mixer and onto the device as well
(Services/Audio/AlertAudioOutput: one WaveOutEvent + buffered float provider).
Why the move: the creator asked that alert audio — the clip's track or the added sound byte —
appear in the desktop sound bar. Only audio that reaches the default device is picked up by the
WASAPI loopback that feeds both the meter and the stream. The old EnqueueAlertAudio route put the
sound in the stream but left the meter flat and the room silent.
Tests: the sound byte and its loop flag round-trip through SQLite, and a fresh alert layer starts
with no sound byte and no loop. Release 0 warnings.
Creator rulings, 2026-11-01.
- Master strip is 44px (from 36) and its meter is now the largest on screen: 420x14 with 32
segments, centred under the preview, with a 12px MASTER label — bigger than the 9px bay
labels. L/R imbalance is a flag on the left, MONO and the session clock on the right.
- The kbps / fps / dropped counters are gone from that line: the live readouts already sit
above the preview, and the duplicate was noise rather than telemetry.
- TRAX is its own bay (MIC | GAME | TRAX | LIP-SYNC) with its own meter bound to
TraxMeterFraction. It lived inside the game bay with no ladder, which meant whether the bed
was actually playing could not be answered from the dock — and the player already measures
its own output.
- Lip-sync is narrow (0.45 star) since it is one slider and three presets; the three sound bays
are equal width, so their meters keep the same relative size.
AudioDockLayout moves with it (156 = 112 + 44; collapsed 44) and the layout test is updated.
TraxBayTests now asserts the opposite of the old ruling: the bay HAS a meter, and the game bay
no longer carries it.
The blur is universal, so it would swallow the logo along with everything else. The compositor
now defers every visible brand logo: skipped in both element loops, blitted immediately AFTER
the blur group, before the flash/social/ticker overlays. One logo per scene, so it is cheap.
Preview mirrors it: the staged scene's brand logo is drawn above the blur host (StagedBrandLogo),
so what you see in the editor is what the encoder gets.
Test: a blur covering the logo's area leaves the logo's pixels exactly white while the coloured
background beneath it blends.
The Blur item's Visibility is bound to CanAddBlur, which depends on the staged scene. The scene
setter never raised it, so the binding evaluated once (collapsed) and stayed collapsed for the
session — build 1082: the option simply wasn't there.
StagedScene now notifies CanAddBlur, with a test that pins both halves: Live true, Chat false,
and a notification on every staged-scene change.
