+# Real-time H.264 recording
+
+The default recorder (`RawBgraRecorderSink`) writes uncompressed BGRA to disk
+and ships a `convert.cmd` for post-recording FFmpeg encoding. That's safe
+(no extra dependencies, works without an encoder installed) but disk-heavy:
+1080p60 = ~500 MB/s, 720p30 = ~88 MB/s.
+
+For long shows or operators on slower disks, the engine ships a
+**`MediaFoundationRecorderSink`** that encodes to H.264 in real time using
+Windows Media Foundation. Inline encoding cuts disk pressure ~10× and
+produces a finished `.mp4` without the convert step.
+
+It's behind a build flag because activating it requires adding a NuGet
+dependency. The structural code is already in
+`src/TeamsISO.Engine/Pipeline/MediaFoundationRecorderSink.cs`.
+
+## Activating it
+
+1. **Add the NuGet dependency** to the engine project:
+
+ dotnet add src/TeamsISO.Engine package Vortice.MediaFoundation --version 3.6.2
+
+ (Pin to a known-good version — Vortice's API surface is stable across
+ 3.6.x but the engine code targets the namespaces in 3.6.x. If a newer
+ major version changes namespaces, the file may need adjustment.)
+
+2. **Define the `MF_AVAILABLE` build symbol** in `TeamsISO.Engine.csproj`:
+
+ ```xml
+
+ $(DefineConstants);MF_AVAILABLE
+
+ ```
+
+3. **Swap the recorder factory** in `IsoController.EnableIsoAsync`:
+
+ ```csharp
+ // Old:
+ recorder = new RawBgraRecorderSink(_loggerFactory.CreateLogger());
+ // New:
+ recorder = new MediaFoundationRecorderSink(_loggerFactory.CreateLogger());
+ ```
+
+ Both classes implement `IRecorderSink` so the rest of the pipeline is
+ unchanged.
+
+4. **Build and smoke-test.** Existing unit tests don't touch the recorder;
+ the integration tier covers it once you've enabled MF.
+
+## What the MF recorder produces
+
+For each enabled ISO with recording on:
+- `//output.mp4` — H.264 video at the engine's
+ configured resolution / framerate, target bitrate ~0.07 bits/pixel
+ (~7 Mbps for 1080p30, ~3 Mbps for 720p30).
+- `//markers.txt` — tab-separated marker offsets
+ from `IIsoController.AddRecordingMarker`. Manually chapter the .mp4 with
+ `mp4chaps -c -i markers.txt output.mp4` (mp4chaps from the `mp4v2` tools).
+
+## Trade-offs vs. RawBgraRecorderSink
+
+| | Raw BGRA | Media Foundation H.264 |
+| --------------------- | --------------- | ---------------------- |
+| Dependencies | None | Vortice.MediaFoundation NuGet |
+| Disk @ 1080p60 | ~500 MB/s | ~50 MB/s |
+| Disk @ 720p30 | ~88 MB/s | ~9 MB/s |
+| CPU | Negligible | Moderate (inline encode) |
+| Output | `.bgra` + `convert.cmd` for FFmpeg post-pass | Finished `.mp4` |
+| Markers in container | No (sidecar JSON) | Sidecar `.txt`, chapter via mp4chaps |
+| Reliable on legacy GPUs | Yes | Yes (MF falls back to software encoder if no hw H.264) |
+
+If your target machines have NVIDIA NVENC / Intel QuickSync, MF will use
+the hardware encoder transparently — that's the path that gives you
+multi-stream realtime H.264 with low CPU.
