Footer shows recording drive free space 
Operators recording long shows previously had to open File Explorer to check disk pressure. New '· 245 GB free' indicator next to the REC badge polls DriveInfo on the recording drive at the existing 1Hz stats tick. Coral tint kicks in below 10GB; existing DiskSpaceWatcher still auto-disables recording at 1GB as a hard safety net.

FormatBytes helper produces footer-readable strings: '1.2 TB' / '245 GB' (no decimal for 100+ GB to avoid clutter) / '8.4 GB' (decimal for the low-warning case) / '450 MB'.

Polling is wrapped in try/catch — network paths occasionally throw, and disk-space display is a comfort feature, not a critical signal.

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.

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
