Per-Participant NDI ISO Controller for Microsoft Teams. Receives Teams NDI streams, normalizes framerate/resolution, and re-emits clean ISO outputs for live production switchers (vMix, OBS, Ross). Wild Dragon LLC.
First step of the WinUI 3 replatform per the approved redesign brief.
The new project coexists with the existing src/TeamsISO.App (WPF) so the
WPF host keeps building and shipping while the WinUI 3 redesign lands
incrementally. Once the WinUI 3 build is feature-complete and tested
against a real Teams meeting, the WPF project is retired.
Scaffold contents:
* src/TeamsISO.App.WinUI/TeamsISO.App.WinUI.csproj
Windows App SDK 1.6 LTS (250602001), unpackaged mode
(WindowsPackageType=None) so the existing MSI installer keeps working.
Target framework net8.0-windows10.0.19041.0, min platform 10.0.17763.0
to preserve Win10 1809+ compatibility for working broadcast hardware.
Pins WindowsSdkPackageVersion=10.0.19041.38 so .NET SDK 8.0.301 builds
cleanly without an SDK upgrade on the build host.
* src/TeamsISO.App.WinUI/app.manifest
PerMonitorV2 DPI awareness + gdiScaling for crisp text on high-DPI
broadcast monitors. asInvoker trust level (control surface :9755 and
OSC :9000 bind to 127.0.0.1, no admin needed).
* App.xaml + App.xaml.cs
Minimal startup: brings up MainWindow. The full pipeline (NDI runtime
preflight, IsoController wiring, single-instance mutex, REST + OSC
bridge, tray icon, crash diagnostics, auto-update banner, onboarding)
migrates in subsequent commits.
* Themes/Tokens.xaml
Wild Dragon design tokens as ThemeDictionary entries (Default = Dark,
Light). Colors as Color resources, Brushes paired per theme so
{ThemeResource} auto-swaps when RequestedTheme flips — no app restart,
no flicker. Spacing/radii/typography tokens are theme-agnostic at the
outer level. Light palette maintains brand recognition via cyan-tinted
off-whites (#FAFAFB canvas, #F0F1F3 rail) rather than pure white, and
splits cyan into accent.cyan.surface (#97EDF0, works in both modes
because text on top is near-black) and accent.cyan.text (#97EDF0 dark
/ #0E7C82 light) so captions and inline labels keep AA contrast.
* Themes/Controls.xaml
Button hierarchy with real commitments: Primary (cyan fill, one per
surface), Secondary (transparent bordered), Tertiary (text only),
Destructive (coral border + text), Caption (titlebar), RailIcon.
Typographic ramp (Display / Title / Heading / Body / Subtle / Caption
/ Mono) at the DESIGN.md 1.25 ratio.
* CommunityToolkit.WinUI.UI.Controls.DataGrid 7.1.2 referenced for the
participants table migration. (Toolkit 8.x dropped DataGrid; 7.x is
the only currently-maintained free option for WinUI 3.)
* Inter.ttf + JetBrainsMono.ttf + dragon-mark.png + teamsiso.ico copied
from the WPF project's Assets/ so the WinUI 3 host is self-contained.
* TeamsISO.sln + TeamsISO.Windows.slnf updated to include the new
project. The .slnf paths switch to backslash form so MSBuild can match
them against the .sln's canonical path representation.
Verified: dotnet build TeamsISO.Windows.slnf -c Debug succeeds with 0
warnings and 0 errors for all 8 projects (WPF host, WinUI 3 host, engine,
NDI interop, console, three test projects).

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
127.0.0.1:9755and OSC on UDP127.0.0.1:9000for Bitfocus Companion / Stream Deck / TouchOSC integration. Self-contained HTML control panel at/uifor 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.
Build
Requires .NET 8 SDK on Windows (the TeamsISO.App host is net8.0-windows
WPF).
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
Documentation
- Control surface API — REST + WebSocket + OSC reference with curl recipes and a Companion config example.
- Releasing — tag-push workflow, MSI signing path.
- Architecture spec — design overview.
- Embedded Teams orchestration spec — Phase E roadmap.
