In-call control bar now drives the live Teams app via UIAutomation:
* Mute button → TeamsControlBridge.ToggleMute()
* Camera button → TeamsControlBridge.ToggleCamera()
* Share button → TeamsControlBridge.OpenShareTray()
* Leave button → TeamsControlBridge.LeaveCall()
Each button reports the result through the status bar (Invoked /
Teams-not-running / Control-not-visible / Invoke-failed).
Rail buttons also wired:
* Launch / surface Teams → TeamsLauncher.IsRunning()/TryLaunch()/ShowWindows()
* Hide / show Teams windows → TeamsLauncher.HideWindows()/ShowWindows()
with a _teamsHidden flag tracking the toggle state
The Marker button was already command-bound to MainViewModel.DropRecording
MarkerCommand (which fans out to IIsoController.AddRecordingMarker), so
the only thing that wasn't covered before is the Teams-side stuff.
Implementation notes:
* Services/TeamsControlBridge.cs and Services/TeamsLauncher.cs are
copied verbatim from src/TeamsISO.App/Services/ with only the
namespace adjusted (TeamsISO.App.Services → TeamsISO.App.WinUI.
Services). Neither file has WPF-specific dependencies — they use
System.Windows.Automation (UIAutomationClient) which works
identically across WPF and WinUI 3 builds. Duplication is
acceptable migration debt; the long-term plan is to lift these
into a shared TeamsISO.App.Shared library once both hosts
stabilize.
* DescribeBridgeResult maps the InvokeResult enum to operator-tone
status text so a failing mute reads "Mute failed — control not
visible (not in a call?)" instead of an opaque "ControlNotFound".
The in-call bar now does what the WPF host's in-call bar does, minus
the MUTED / CAM OFF state pills (those would need a 1Hz UIA poll of
the Teams call state — wire-up to come).

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.
A ground-up GUI redesign is in flight on main (see
docs/superpowers/plans/2026-05-12-winui3-migration.md). The WPF host
(src/TeamsISO.App/) remains the shipping build; a parallel WinUI 3 host
(src/TeamsISO.App.WinUI/) is scaffolded with the redesigned MainWindow,
theme system (dark + light), and secondary surfaces. Activation of the
unpackaged WinUI 3 .exe is the current blocker — diagnostics in the
migration plan's Phase 3.
Build
Requires .NET 8 SDK on Windows. The repo has two hosts:
src/TeamsISO.App— WPF,net8.0-windows, current shipping buildsrc/TeamsISO.App.WinUI— WinUI 3,net8.0-windows10.0.19041.0, in-flight
Both build together 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
