# 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`](docs/CONTROL-SURFACE.md) 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.

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 build
- `src/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
