🎯 WHAT IT DOES

✅ Timestamp Communication - C# sends millisecond-precise timestamps to C++ ✅ Preset Queuing - C# queues presets to play at specific times ✅ Audio Synchronization - Audio preview syncs with preset queue ✅ Real-time UI - C# UI displays queue sorted by timestamp ✅ Preset Management - Add/delete presets with user-friendly UI ✅ Automatic Switching - C++ automatically loads correct preset at correct time ✅ Thread-safe - All operations are thread-safe and reliable

🚀 GETTING STARTED

Quick Start (5 minutes)

1. Open: README_IPC.md
2. Read: IPC_QUICKSTART.md
3. Done! Ready for setup

Integration (45 minutes)

1. Copy C++ files to src/sdl-test-ui/
2. Update CMakeLists.txt (see CMAKE_IPC_INTEGRATION.md)
3. Integrate with pmSDL (4 modifications)
4. Build and test

Create C# Client (15 minutes)

1. Copy CSharpIPCClient_Example.cs
2. Create UI or use CSharpWinformsUI_Example.cs
3. Done!

Total: ~1 hour

🎓 HOW IT WORKS

The Flow:

C# App (Music Player + UI)
        ↓
        └─→ SendTimestamp(5000ms)
                ↓
            [JSON Message]
                ↓
        C++ projectM Visualizer
        ↓
        Check: Should preset change at 5000ms?
        ↓
        Yes! Load "cool.milk" preset
        ↓
        Send confirmation back to C#
        ↓
        C# UI: Update display
        ↓
        Visualizer: Display new preset

What Each Component Does:

IPCHandler:

  • Manages stdin/stdout communication
  • Serializes/deserializes JSON
  • Runs listening thread

PresetQueueManager:

  • Stores presets with timestamps
  • Keeps them sorted
  • Queries current preset

AudioPreviewManager:

  • Tracks playback position
  • Manages play/pause/stop
  • Synchronizes timing

IPCManager:

  • Coordinates everything
  • Routes messages
  • Manages state

ProjectMIPCClient (C#):

  • High-level client API
  • Process management
  • Event system

💡 QUICK EXAMPLE

C++ Usage

// In render loop
ipcManager->getAudioPreview().updateCurrentTimestamp(currentTimeMs);
std::string preset = ipcManager->getPresetQueue()
    .getPresetAtTimestamp(currentTimeMs);
if (!preset.empty()) loadPreset(preset);

C# Usage

client.LoadPreset("cool.milk", 5000);
client.StartPreview(0);
client.SendTimestamp(2500);  // Every frame/update
