+# Video Orchestra - VP9 Multi-Stream Decoder for Godot Engine
+
+## Project Overview
+A high-performance VP9 video decoding system for Godot Engine 4.4.1 that supports simultaneous decoding of 3 alpha-channel VP9 video streams using hardware acceleration on Android and iOS platforms.
+
+## Architecture Design
+
+### Core Components
+1. **VideoOrchestra Manager (C#)** - Main orchestration layer
+2. **Native Decoder Interface (C#)** - Platform abstraction layer
+3. **Android Native Library (C++)** - MediaCodec-based VP9 decoder
+4. **iOS Native Library (C++)** - VideoToolbox-based VP9 decoder (future)
+5. **Texture Pipeline** - Direct native texture rendering to Godot
+
+### Data Flow
+```
+VP9 Stream → Native Decoder → Hardware Codec → Texture Buffer → Godot Renderer
+```
+
+## Android Implementation Plan
+
+### 1. Hardware Decoder (MediaCodec)
+- **MediaCodec API Usage**: Leverage Android's MediaCodec for VP9 hardware decoding
+- **Surface Integration**: Use Surface API for direct texture output
+- **Alpha Channel Support**: Ensure VP9 alpha channel preservation
+- **Multi-stream Management**: Handle 3 concurrent decoder instances
+
+### 2. Native Library Architecture
+```cpp
+// Core decoder interface
+class VP9Decoder {
+    bool initialize(int width, int height);
+    bool decodeFrame(uint8_t* data, size_t size, int streamId);
+    uint32_t getTextureId(int streamId);
+    void release();
+};
+
+// Android implementation
+class AndroidVP9Decoder : public VP9Decoder {
+    AMediaCodec* codec[3];  // 3 decoder instances
+    ANativeWindow* surface[3];  // Direct surface rendering
+    // MediaCodec implementation
+};
+```
+
+### 3. C# Interface Layer
+```csharp
+// Godot-friendly VP9 decoder manager
+public class VideoOrchestraManager : Node {
+    private AndroidVP9Native nativeDecoder;
+    
+    public bool InitializeDecoders(int width, int height);
+    public bool DecodeFrame(byte[] data, int streamId);
+    public ImageTexture GetTexture(int streamId);
+}
+
+// Platform abstraction
+public interface IVP9Native {
+    bool Initialize(int width, int height);
+    bool DecodeFrame(byte[] data, int streamId);
+    uint GetTextureId(int streamId);
+}
+```
+
+### 4. Godot Integration
+- **Custom Resource Types**: VP9Stream resource for stream management
+- **Node Structure**: VideoOrchestraManager as main node
+- **Texture Binding**: Direct OpenGL texture ID binding
+- **Performance Optimization**: GPU memory management
+
+## Directory Structure

+   - Example: `ANDROID_NDK_HOME=C:\Android\Sdk\ndk\25.1.8937393`
+
+#### Building Android Library
+
+##### Option 1: Simplified Build (Java only)
+```bash
+# Windows - Creates library without native VP9 decoder
+build_android.bat
+
+# Status: ✅ Working - Creates basic Android library for Godot integration
+```
+
+##### Option 2: Full Build (With native VP9)
+```bash
+# First, uncomment NDK configuration in android/gradle/build.gradle
+# Then run:
+build_android.bat
+
+# Status: 🚧 Requires Android SDK/NDK setup
+```
+
+#### Build Troubleshooting
+
+##### Common Issues:
+
+**1. "gradlew not found"**
+- ✅ Fixed: Gradle wrapper files are now included
+- Solution: Use updated `build_android.bat`
+
+**2. "Java not found"**
+```bash
+Error: Java not found in PATH
+```
+- Solution: Install Java 8+ and add to PATH
+- Download: https://adoptium.net/
+
+**3. "Android SDK not found"**
+```bash
+Warning: ANDROID_HOME not set
+```
+- Solution: Install Android SDK and set environment variable
+- Set: `ANDROID_HOME=C:\Path\To\Android\Sdk`
+
+**4. "NDK build failed"**
+```bash
+Error: ndk-build command not found
+```
+- Solution: Install Android NDK and update build.gradle
+- Uncomment NDK configuration sections
+
+**5. "Build successful but no native decoding"**
+- Expected behavior with simplified build
+- Java-only library allows Godot integration testing
+- For full VP9 decoding, complete NDK setup required
+
+#### Godot Project Setup
+1. **Open Project**: Launch Godot 4.4.1 and open `godot-project/project.godot`
+2. **Build C# Assembly**: Project → Tools → C# → Create C# Solution
+3. **Configure Android Export**:
+   - Project → Export → Add Android template
+   - Enable "VP9 Orchestra" plugin in export settings
+   - Set minimum API level to 21
+   - Configure signing if needed
+
+#### Testing
+1. **Run Test Scene**: Launch `Main.tscn` in Godot editor
+2. **Load Test Streams**: Click "Load VP9 Streams" button
+3. **Start Playback**: Click "Play" to begin decoding simulation
+4. **Monitor Output**: Check debug console for decoder status
+
+### Technical Architecture
+
+#### MediaCodec Integration
+```cpp
+// Hardware VP9 decoding pipeline
+VP9 Stream → MediaCodec → Surface → OpenGL Texture → Godot
+```
+
+#### Memory Management
+- **Texture Buffers**: Direct GPU memory allocation
+- **Stream Isolation**: Separate decoder instances per stream
+- **Resource Cleanup**: Automatic cleanup on scene exit
+
+#### Performance Characteristics
+- **Target**: 3x1920x1080 VP9 streams at 60fps
+- **Memory**: ~100MB texture buffer allocation
+- **Latency**: <16ms decode-to-render pipeline
+
+### Known Limitations & TODOs
+
+#### Current Limitations
+1. **Test Data**: Currently uses dummy VP9 frames (not real video)
+2. **Surface Integration**: Simplified Surface/Texture binding (needs full implementation)
+3. **Error Handling**: Basic error handling (needs comprehensive error recovery)
+4. **Performance**: Not optimized for production use
+
+#### Future Enhancements
+1. **Real VP9 Files**: Support for loading actual .vp9 video files
+2. **Sync Playback**: Frame synchronization across all 3 streams
+3. **Software Fallback**: libvpx integration for cross-platform software decoding
+4. **iOS Support**: VideoToolbox implementation
+5. **Memory Optimization**: Advanced texture memory management
+
+### Production Deployment
+
+#### Device Compatibility
+- **Minimum**: Android API 21 (Android 5.0)
+- **Recommended**: API 24+ with VP9 hardware support
+- **Software Fallback**: libvpx cross-platform decoder
+
+#### Performance Testing
+```bash
+# Recommended test devices:
+# - High-end: Snapdragon 8 Gen series, Exynos 2xxx series
+# - Mid-range: Snapdragon 7 series, MediaTek Dimensity
+# - Entry: Snapdragon 6 series with VP9 support
+```
+
+### Troubleshooting
+
+#### Common Issues
+1. **Library Not Found**: Ensure AAR is built and copied correctly
+2. **MediaCodec Errors**: Check device VP9 hardware support
+3. **Texture Issues**: Verify OpenGL context and surface creation
+4. **Performance**: Monitor GPU memory usage and decoder queue depth
+
+#### Debug Commands
+```bash
+# Check MediaCodec capabilities
+adb shell dumpsys media.codec_capabilities | grep -i vp9
+
+# Monitor GPU usage
+adb shell dumpsys gfxinfo com.yourpackage.name
+
+# Native debugging
+adb shell setprop debug.videoorchestra.log 1
+```
+
+## Cross-Platform Software Decoder Implementation (libvpx)
+
+### Software Fallback Strategy
+For devices without hardware VP9 support or when hardware decoders fail, the project uses **libvpx** as the cross-platform software decoder solution.
+
+#### libvpx Advantages
+- **Official VP9 Implementation**: Google's reference VP9 decoder library
+- **Proven Performance**: Industry-standard implementation with extensive optimizations
+- **License**: BSD 3-Clause license - commercial-friendly
+- **Multi-threading**: Built-in support for concurrent decoding
+- **Alpha Channel**: Native VP9 alpha channel support
+- **Cross-Platform**: Windows, Android, iOS, macOS, Linux support
+
+### libvpx Integration Architecture
+
+#### Native Library Structure
+```cpp
+// Software VP9 decoder using libvpx
+class LibvpxVP9Decoder {
+    vpx_codec_ctx_t codec_ctx[MAX_VP9_STREAMS];
+    vpx_codec_dec_cfg_t dec_cfg;
+    
+    bool initialize(int width, int height);
+    bool decode_frame(const uint8_t* data, size_t size, int stream_id);
+    vpx_image_t* get_decoded_frame(int stream_id);
+    void release();
+};
+```
+
+#### C# Platform Implementation
+```csharp
+// scripts/Platform/Software/SoftwareVP9Decoder.cs
+public class SoftwareVP9Decoder : IVP9PlatformDecoder 
+{
+    // libvpx P/Invoke declarations
+    [DllImport("libvpx")]
+    private static extern int vpx_codec_dec_init_ver(...);
+    
+    [DllImport("libvpx")]
+    private static extern int vpx_codec_decode(...);
+    
+    // Multi-threaded software decoding
+    private Thread[] decodingThreads;
+    private ConcurrentQueue<DecodeTask>[] taskQueues;
+}
+```
+
+### Performance Optimization Strategy
+
+#### Hardware vs Software Decision Matrix
+| Device Capability | Primary Decoder | Fallback | Max Streams |
+|-------------------|----------------|----------|-------------|
+| High-end + HW VP9 | MediaCodec/MF | libvpx | 3 |
+| Mid-range + HW VP9 | MediaCodec/MF | libvpx | 2 |
+| High-end CPU only | libvpx | Simulation | 2 |
+| Low-end devices | Simulation | - | 1 |
+
+#### libvpx Performance Tuning
+- **Multi-threading**: 1 thread per stream + 1 coordinator thread
+- **Memory Pool**: Pre-allocated frame buffers
+- **SIMD Optimization**: ARM NEON, x86 SSE/AVX utilization
+- **Dynamic Quality**: Automatic quality reduction under CPU pressure
+
+### Build Integration
+
+#### Platform-Specific libvpx Builds
+```makefile
+# Android NDK (android/jni/Android.mk)
+LOCAL_STATIC_LIBRARIES += libvpx
+LOCAL_CFLAGS += -DHAVE_NEON
+
+# Windows (CMake/vcpkg)
+find_package(libvpx REQUIRED)
+target_link_libraries(vp9orchestra libvpx)
+
+# iOS (CocoaPods/Podfile)
+pod 'libvpx', '~> 1.13.0'
+```
+
+#### Fallback Logic Implementation
+```csharp
+// Platform factory enhancement
+public static IVP9PlatformDecoder CreateDecoder(bool preferHardware = true)
+{
+    string platform = OS.GetName().ToLower();
+    
+    try {
+        // Try hardware first
+        var hardwareDecoder = CreateHardwareDecoder(platform);
+        if (hardwareDecoder?.Initialize() == true) {
+            return hardwareDecoder;
+        }
+    } catch (Exception ex) {
+        GD.PrintWarn($"Hardware decoder failed: {ex.Message}");
+    }
+    
+    // Fallback to libvpx software decoder
+    GD.Print("Falling back to libvpx software decoder");
+    return new SoftwareVP9Decoder(); // libvpx-based
+}
+```
+
+### Expected Performance Characteristics
+
+#### Software Decoder Performance (libvpx)
+- **1080p Single Stream**: 30-60fps on modern CPUs
+- **1080p Triple Stream**: 15-30fps on high-end CPUs

+* vp9 하드웨어 코덱을 반드시 사용하여 디코딩해야 하고, 디코딩된 이미지 텍스처를 Godot Engine 에 직접 native로 렌더링해야한다.
+* 하드웨어 코덱을 사용하려면 MediaCodec 를 써야할 것으로 알고 있다.
+* 하드웨어 코덱을 지원하지 않는 단말기를 위해서라도 dav1d 라이브러리를 추후에 탑재할 필요가 있다.

+
+
+작업 설계 및 구현 과정을 CLAUDE.md 에 정리해준다.
+그 다음에 Godot Engine 기본 프로젝트 파일을 만든다.
+Android 단말기를 위해서 개발한다.
+iOS 단말기 개발은 추후에 별도로 진행한다.
