Zac Gaetano 33fca8e955 polish(mainwindow): empty state, table widths, strings, theme tooltip 
Walks the v2 polish punch list against MainWindow.

- Theme button tooltip is now "Theme (System / Dark / Light)" per the
  v2 shape brief, replacing the previous "Toggle theme (Ctrl+T)".
- Participants table column widths match spec: Output 130px (was 150),
  ISO pill 100px (was 110). The 24px state LED, 110px audio meter, and
  52px row height already matched. The 106px Preview thumbnail column
  and 32px gear-button column are intentional deviations (live thumbs
  were restored at 4944de5; per-ISO override gear added at the same
  time) and are now called out in the column-spec comment so a future
  reader doesn't try to "fix" them.
- Empty-state placeholder finally renders when ParticipantCount == 0:
  mono sentence "no ndi sources yet — open teams and start a meeting"
  + a tertiary Refresh discovery button — exactly the copy specified
  by the shape brief's empty-states section. CountToVisibilityConverter
  is now declared in MainWindow.Resources (it shipped as a class but
  was never registered).
- OnClosing wraps WindowStateStore.Save in a try/catch so a serialization
  or filesystem fault on shutdown can never block the window from
  closing. Save itself already swallows its own IO errors; this is
  defense-in-depth for anything that escapes.
- MessageBox copy in MainWindow.xaml.cs (Hide/show Teams, Launch Teams,
  Stop Teams) moves to Properties/Strings.resx + a hand-written
  Properties/Strings.Designer.cs accessor. ResourceManager reads it by
  basename "TeamsISO.App.Properties.Strings"; LogicalName is set on the
  EmbeddedResource so the manifest name is predictable regardless of
  how MSBuild would otherwise compute it. Future-localization seam.
  OnLaunchTeamsRightClick's confirmation dialog is intentional — it
  guards a destructive mid-show action — and the code-behind comment
  now says so; the palette also offers Stop Teams as the keyboard
  surface, so the right-click affordance isn't the only one.

Build clean (0 warnings, 0 errors); 160 tests still pass (56 App +
104 Engine, Category!=ndi&requires!=ndi filter).

TeamsISO

Per-Participant NDI ISO Controller for Microsoft Teams.

TeamsISO sits between Microsoft Teams' raw NDI broadcast output and a live-production environment. It receives each participant's NDI stream, normalizes framerate / resolution / aspect / audio per a configured target, and re-emits clean, individually-addressable NDI sources for ingestion into a switcher (vMix, OBS, Ross, hardware capture).

What it does

  • Discovers participants as Teams broadcasts each one over NDI, surfacing the operator-friendly display name (handles current "MS Teams - Name" format and the legacy "(Teams) Name" format).
  • Normalizes feeds to a consistent framerate, resolution, aspect mode, and audio routing — so the downstream switcher gets predictable inputs regardless of what each participant's webcam is doing.
  • Routes per-participant as separate NDI sources with a configurable output-name template (TEAMSISO_{name}, {guid}, {machine}, {timestamp} tokens).
  • Records each ISO to disk simultaneously — raw BGRA + sidecar manifest.json
    • ffmpeg convert.cmd — so post-production gets a clean per-guest archive.
  • Embeds Teams orchestration: launch and stop Teams from the rail, hide Teams' UI windows during a show, drive in-call controls (mute, camera, share, leave, raise hand) via UIAutomation.
  • Operator presets save the current per-participant ISO assignment and custom output names, applicable on next launch automatically.
  • Live preview thumbnails per participant in the participants table, plus pop-out floating preview windows (right-click → Open preview…) for multi-monitor monitoring.
  • External control surface — REST + WebSocket on 127.0.0.1:9755 and OSC on UDP 127.0.0.1:9000 for Bitfocus Companion / Stream Deck / TouchOSC integration. Self-contained HTML control panel at /ui for phone-as-controller.
  • Crash diagnostics wired to a rolling daily Serilog file sink under %LOCALAPPDATA%\TeamsISO\Logs\.
  • Update check against forge.wilddragon.net's release API — manual or silent on launch (throttled to 24h).
  • Diagnostic bundle export zips logs + config + presets for bug reports.

Status

Pre-1.0. The May 2026 batch is feature-complete; v1.0 cut is gated on code-signing the MSI and a smoke pass against a real Teams meeting. See CHANGELOG.md for the [Unreleased] entry.

The May 2026 ground-up redesign — the v2 "Studio Terminal" shell — has landed on the WPF host (src/TeamsISO.App/). A WinUI 3 replatform was explored in early May 2026 and abandoned (activation blockers + redundant work given the redesign is purely XAML / view-layer); the brief lives at docs/shapes/2026-05-13-teamsiso-v2-studio-terminal.md, and the abandoned migration plan + bootstrap probe are archived under docs/archive/.

Build

Requires .NET 8 SDK on Windows. WPF is the only host:

  • src/TeamsISO.App — WPF, net8.0-windows, the shipping build

Build from the solution filter:

dotnet restore TeamsISO.Windows.slnf
dotnet build TeamsISO.Windows.slnf -c Release
dotnet test TeamsISO.Windows.slnf --filter "Category!=ndi&requires!=ndi"

The shipped helper scripts in the repo root automate this:

pwsh -File .\build-and-test.ps1
pwsh -File .\commit-and-push.ps1
