+# AGENTS.md — Branch Output Plugin for OBS Studio
+
+## Project Overview
+
+**Branch Output** is an OBS Studio plugin (shared library / module) that adds an effect filter allowing
+individual sources or scenes to stream and/or record independently from the main OBS output.
+It is developed and maintained by **OPENSPHERE Inc.** under the GPLv2+ license.
+
+- Repository language: **C++ 17** with **Qt 6** for UI
+- Build system: **CMake** (≥ 3.16)
+- Based on the official [obs-plugintemplate](https://github.com/obsproject/obs-plugintemplate)
+- Target OBS Studio version: **≥ 30.1.0** (Qt6, x64 / ARM64 / Apple Silicon)

+# With Inno Setup installer
+.\build.ps1 -installer
+```
+
+Or manually:
+
+```powershell
+cmake --fresh -S . -B build_x64 -G "Visual Studio 17 2022" -A x64
+cmake --build build_x64 --config RelWithDebInfo
+cmake --install build_x64 --prefix release/Package --config RelWithDebInfo
+```
+
+### CMake Presets
+
+Use `cmake --preset <name>` with one of:
+- `windows-x64` / `windows-ci-x64`
+- `macos` / `macos-ci`
+- `linux-x86_64` / `linux-ci-x86_64`
+
+---
+
+## Architecture & Key Concepts
+
+### Plugin Entry Point
+
+The plugin registers an OBS **effect filter** via `obs_source_info` (filter ID: `osi_branch_output`).
+The main class is `BranchOutputFilter` (declared in `plugin-main.hpp`), which is a `QObject` subclass.
+
+### Core Responsibilities of BranchOutputFilter
+
+| Area | Description |
+|------|-------------|
+| **Streaming** | Creates up to `MAX_SERVICES` (8) independent streaming outputs with dedicated services, encoders, and reconnect logic. |
+| **Recording** | Supports file recording with various container formats, time/size-based splitting, pause/unpause, and chapter markers. |
+| **Audio** | Manages up to `MAX_AUDIO_MIXES` audio contexts via `AudioCapture` class. Supports filter audio, per-source audio, and audio track selection. |
+| **Video** | Creates an OBS view (`obs_view_t`) with a private video output for per-filter encoding and resolution control. |
+| **UI** | Properties panel built via OBS properties API (`plugin-ui.cpp`). Status dock (`BranchOutputStatusDock`) shows live statistics for all filters. |
+| **Hotkeys** | Registers hotkey pairs for enable/disable, split recording, pause/unpause, and chapter markers. |
+| **Interlock** | Can link filter activation to OBS streaming, recording, or virtual camera states. |
+| **Blanking** | Uses a private solid-color source to blank output when the parent source is inactive. |
+
+### Threading Model
+
+- OBS callbacks (video render, audio filter, video tick) may run on **different threads** from the UI thread.
+- `pthread_mutex_t outputMutex` protects streaming/recording output state.
+- `QMutex` protects audio buffers in `AudioCapture`.
+- UI updates use `QMetaObject::invokeMethod` with `Qt::QueuedConnection` for thread safety.
+- Settings changes are tracked via revision counters (`storedSettingsRev` / `activeSettingsRev`) to defer restarts.
+
+### OBS API Usage
+
+The plugin heavily uses:
+- `obs-module.h` — Module registration, locale, config paths
+- `obs-frontend-api.h` — Profile config, scene enumeration, frontend events
+- `obs.hpp` — OBS RAII wrappers (`OBSSourceAutoRelease`, `OBSEncoderAutoRelease`, `OBSOutputAutoRelease`, etc.)
+- `util/deque.h`, `util/threading.h`, `util/platform.h` — Low-level utilities
+
+---
+
+## Code Style & Formatting
+
+### C++ (clang-format)
+
+- **Standard**: C++17
+- **Column limit**: 120
+- **Indent**: 4 spaces (tabs not used)
+- **Brace style**: Custom — functions use next-line braces; control statements use same-line braces
+- **clang-format version**: ≥ 16 required
+- Run: `clang-format -i src/**/*.cpp src/**/*.hpp`
+
+### CMake (cmake-format)
+
+- **Line width**: 120
+- **Tab size**: 2
+- Config: `.cmake-format.json`
+
+### CI Enforcement
+
+Format is checked in CI via `.github/workflows/check-format.yaml` using reusable actions
+(`run-clang-format`, `run-cmake-format`). PRs and pushes to `master` are validated.
+
+---
+
+## Coding Guidelines
+
+### General Rules
+
+1. **Follow OBS plugin conventions** — Use `obs_log()` for logging, `OBS_DECLARE_MODULE()` for entry, locale via `obs_module_text()`.
+2. **RAII wrappers** — Always use `OBSSourceAutoRelease`, `OBSDataAutoRelease`, etc. instead of manual `obs_*_release()`.
+3. **Thread safety** — Any data shared between OBS callbacks and UI must be guarded by mutex. Use `QMetaObject::invokeMethod` with `Qt::QueuedConnection` when calling UI methods from non-UI threads.
+4. **Settings migration** — When changing settings schema, add backward-compatible migration code in the constructor (see `audio_source` migration example in `BranchOutputFilter` constructor).
+5. **Qt MOC** — Classes using `Q_OBJECT` must be in headers. `AUTOMOC`, `AUTOUIC`, `AUTORCC` are enabled.
+
+### Naming Conventions
+
+- **Classes**: PascalCase (`BranchOutputFilter`, `AudioCapture`, `OutputTableRow`)
+- **Methods**: camelCase (`startOutput`, `stopRecordingOutput`, `onIntervalTimerTimeout`)
+- **Constants/Macros**: UPPER_SNAKE_CASE (`MAX_SERVICES`, `FILTER_ID`, `OUTPUT_MAX_RETRIES`)
+- **Member variables**: camelCase, no prefix (`filterSource`, `videoEncoder`, `recordingActive`)
+- **Static callbacks**: camelCase with descriptive prefix (`onEnableFilterHotkeyPressed`, `audioFilterCallback`)
+
+### Ternary Operators
+
+- **Avoid multi-line ternary expressions** — clang-format cannot reliably format nested or multi-line ternary operators (`a ? b : c`) in a readable way. Use `if`/`else if`/`else` statements instead when the expression would span multiple lines.
+
+### Error Handling
+
+- Use `obs_log(LOG_ERROR, ...)` for errors, `LOG_WARNING` for warnings, `LOG_INFO` for lifecycle events, `LOG_DEBUG` for verbose tracing.
+- Check return values from OBS API calls; handle gracefully (do not crash OBS).
+- Never throw C++ exceptions across OBS API boundaries.
+
+### Localization
+
+- All user-facing strings must use `obs_module_text("Key")` or the `QTStr("Key")` helper.
+- Add new keys to `data/locale/en-US.ini` (primary) and ideally to `ja-JP.ini`.
+- Locale files use INI format: `Key="Value"`.
+
+---
+
+## Testing & Validation
+
+- There are no automated unit tests in this repository currently.
+- **Manual testing** is required: load the plugin in OBS Studio, add the "Branch Output" filter, and verify streaming/recording behavior.
+- Test on all supported platforms when possible (Windows x64, macOS, Linux).
+- Verify Studio Mode compatibility (Branch Output ignores studio mode's program and outputs from preview).
+- Verify that enabling and then disabling the Branch Output filter does not cause a crash.
+- Verify that shutting down OBS does not crash when the Branch Output filter is inactive or active, respectively.
+- Verify that switching scene collections does not crash when the Branch Output filter is inactive or active, respectively.
+- Verify that no memory leaks are logged on OBS shutdown.
+- Verify that mutex does not cause deadlocks.

+
+## Common Tasks for AI Agents
+
+### Adding a New Setting / Feature
+
+1. Add the setting key to `BranchOutputFilter::getDefaults()` in `plugin-main.cpp`.
+2. Add UI controls in `plugin-ui.cpp` (use OBS properties API: `obs_properties_add_*`).
+3. Handle the setting in `startOutput()` / `stopOutput()` / `updateCallback()` as needed.
+4. Add locale strings to **all** locale files under `data/locale/` (`en-US.ini`, `ja-JP.ini`, `zh-CN.ini`, `ko-KR.ini`, `de-DE.ini`, `fr-FR.ini`, `ca-ES.ini`, `ro-RO.ini`, `ru-RU.ini`, `uk-UA.ini`). `en-US.ini` is the primary (required); all others should also be updated.
+5. Ensure backward compatibility — existing saved settings must still load correctly.
+
+### Adding a New Streaming Service Slot
+
+- The plugin supports up to `MAX_SERVICES` (8) service slots.
+- Each slot has its own `BranchOutputStreamingContext` with output, service, and signals.
+- Use `getIndexedPropNameFormat()` for indexed property names.
+
+### Modifying Audio Handling
+
+- Audio capture is abstracted through `AudioCapture` class in `src/audio/`.
+- The class manages an audio buffer, supports push/pop patterns, and handles format conversion.
+- Audio mixers and encoder binding are managed in `BranchOutputFilter::startOutput()`.
+
+### Modifying the Status Dock
+
+- `BranchOutputStatusDock` in `src/UI/` is a `QFrame`-based dock widget.
+- It uses a `QTableWidget` with custom cell classes (`OutputTableCellItem`, `LabelCell`, `FilterCell`).
+- Thread-safe updates via `QMetaObject::invokeMethod`.
+
+---
+
+## Important Warnings
+
+- **Do NOT call `obs_filter_get_parent()` in the `BranchOutputFilter` constructor** — it returns `nullptr` at that point. Use `addCallback()` instead.
+- **Private sources** (not visible in frontend) are intentionally excluded from status dock and timer registration.
+- **Settings revisions** (`storedSettingsRev` / `activeSettingsRev`) exist to avoid stopping output during reconnect attempts. Do not bypass this mechanism.
+- **Encoder compatibility** — The plugin maps "simple" encoder names to actual encoder IDs, with version-specific fallbacks (OBS 30 vs OBS 31). See `getSimpleVideoEncoder()` in `utils.hpp`.
+- **Memory management** — Use OBS RAII wrappers. Raw `bfree()` / `obs_data_release()` calls are error-prone.
+- **`.gitignore` uses allowlist pattern** — New top-level files/directories must be explicitly un-ignored with `!` prefix.
