# 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 by a
switcher — vMix, OBS, Ross, hardware capture.

> **Status:** **v1.0.0** — first general release. Windows only. Requires
> Microsoft Teams (with NDI broadcast enabled) and the NDI 6 runtime.

---

## What it does

- **Discovers participants** as Teams broadcasts each one over NDI. Cleans
  the Teams-prefixed source name down to a readable display name.
- **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
  per-row output name. Default is the speaker's display name; override
  inline in the participants table.
- **Records each ISO to disk** simultaneously — raw BGRA + `manifest.json`
  + FFmpeg `convert.cmd` — so post-production gets a clean per-guest archive.
- **Embeds Teams orchestration**: launch / stop Teams, hide its UI windows
  during a show, drive in-call controls (mute, camera, share, leave,
  raise hand) without leaving the operator console.
- **Operator presets** save the current per-participant ISO assignment and
  custom output names, applicable on next launch automatically.
- **Live preview thumbnails** in the participants table, plus pop-out
  floating preview windows 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. Self-contained HTML panel at `/ui` for phone-as-controller.
- **Theme-aware** — dark and light palettes, system-following or pinned.

## Install

Grab the latest MSI from the
[Releases page](https://forge.wilddragon.net/zgaetano/teamsiso/releases),
double-click, and accept the install prompts. Per-machine install under
`C:\Program Files\Wild Dragon\TeamsISO`.

**Prerequisites:**
- Windows 10 / 11, 64-bit
- [.NET 8 Desktop Runtime](https://dotnet.microsoft.com/download/dotnet/8.0)
- [NDI 6 Runtime](https://www.ndi.video/tools/) (the installer warns if
  missing but does not block — operators can stage the app before NDI is
  rolled out)
- Microsoft Teams (NDI broadcast enabled in admin policy)

## Configure

First-run defaults work for most setups. If your downstream switcher needs
a particular framerate / resolution / NDI group routing, open the **gear
icon** in the header to access the settings drawer:

- **Output** — framerate, resolution, aspect mode, audio routing
- **Network** — NDI discovery and output group names
- **App** — recording paths, startup behavior, theme

Per-participant overrides — click the **CFG** column gear on any row to
override framerate / resolution / aspect / audio for just that participant.

  OSC reference with curl recipes and a Companion config example.

## Build from source

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

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

Or use the included helper:

```powershell
pwsh -File .\build-and-test.ps1
```

To produce a fresh MSI:

```powershell
dotnet publish src\TeamsISO.App\TeamsISO.App.csproj `
    -c Release -r win-x64 --self-contained false `
    -o publish\TeamsISO
dotnet build installer\TeamsISO.Installer.wixproj -c Release
# Output: installer\bin\x64\Release\TeamsISO-Setup-<version>.msi
```
