# Android VavCore Lazy Initialization 구현 완료 🎉
**완료일**: 2025년 9월 29일
**상태**: ✅ 완료 - **Critical 마일스톤**
**카테고리**: Android 플랫폼, 시스템 아키텍처, Lazy Initialization
---
## 🎯 **프로젝트 개요**
Android 플랫폼에서 Windows DllMain과 동등한 **Lazy Initialization 시스템**을 구현하여, VavCore 라이브러리의 안전한 초기화와 `vavcore_create_player()` 함수의 완전한 작동을 달성한 Critical 프로젝트입니다.
### **핵심 문제**
- Android에서 `vavcore_create_player()` 함수가 항상 실패
- Windows DllMain과 동등한 초기화 메커니즘 부재
- JNI 래퍼의 반환값 타입 오류로 인한 잘못된 성공/실패 판정
- 디코더 등록 함수의 링킹 오류
### **해결 목표**
- **Windows와 동등한 Android 초기화 시스템 구현**
- **모든 Android AV1 디코더 정상 작동 확인**
- **JNI-C++ 간 완벽한 상호 운용성 확보**
---
## 🔧 **해결된 핵심 문제들**
### **1. Android JNI_OnLoad 시스템 구현** 🏗️
**문제**: Android에는 Windows DllMain과 같은 라이브러리 초기화 메커니즘이 없음
**해결책**:
```cpp
// VavCore.cpp - Android JNI_OnLoad 구현
JNIEXPORT jint JNICALL JNI_OnLoad(JavaVM* vm, void* reserved) {
__android_log_print(ANDROID_LOG_INFO, "VavCore", "JNI_OnLoad: VavCore library loaded");
std::lock_guard<std::mutex> lock(g_mutex);
g_jni_loaded = true;
__android_log_print(ANDROID_LOG_INFO, "VavCore", "JNI_OnLoad: VavCore ready for initialization");
return JNI_VERSION_1_6;
}
static bool IsAndroidLibraryReady() {
return g_jni_loaded;
}
```
**효과**:
- ✅ 라이브러리 로드 시 자동 초기화
- ✅ Windows DllMain과 동등한 기능
- ✅ Thread-safe 초기화 상태 관리
### **2. 디코더 등록 함수 링킹 문제 해결** 🔗
**문제**: `RegisterAV1Decoders()`, `RegisterAndroidMediaCodecDecoders()` 함수 링킹 실패
**원인**: C++ 네임 맹글링으로 인한 심볼 찾기 실패
**해결책**:
```cpp
// AV1Decoder.cpp & AndroidMediaCodecAV1Decoder.cpp
extern "C" void RegisterAV1Decoders() {
VideoDecoderFactory::RegisterAV1Decoder({
"dav1d",
"Software AV1 decoder using dav1d library",
50,
[]() { return true; },
[]() { return std::make_unique<AV1Decoder>(); }
});
}
extern "C" void RegisterAndroidMediaCodecDecoders() {
VideoDecoderFactory::RegisterAV1Decoder({
"mediacodec",
"Android MediaCodec hardware AV1 decoder",
5, // High priority
[]() {
AndroidMediaCodecAV1Decoder temp_decoder;
auto codecs = temp_decoder.GetAvailableCodecs();
return !codecs.empty();
},
[]() { return std::make_unique<AndroidMediaCodecAV1Decoder>(); }
});
}
```
**효과**:
- ✅ 모든 디코더 등록 함수 정상 링킹
- ✅ MediaCodec 하드웨어 가속 디코더 등록 성공
- ✅ dav1d 소프트웨어 디코더 등록 성공
### **3. JNI 반환값 타입 오류 수정** 🔄
**문제**: `VavCoreResult`를 `bool`로 잘못 캐스팅하여 성공을 실패로 오인
**원인**: `VAVCORE_SUCCESS` (값: 0)이 `false`로 변환됨
**해결책**:
```cpp
// vavcore_jni.cpp - 수정 전
bool result = vavcore_initialize(); // ❌ 잘못된 타입
if (result) { // VAVCORE_SUCCESS(0)가 false로 인식
LOGI("VavCore initialized successfully");
return JNI_TRUE;
} else {
LOGE("Failed to initialize VavCore");
return JNI_FALSE;
}
// vavcore_jni.cpp - 수정 후
VavCoreResult result = vavcore_initialize(); // ✅ 올바른 타입
if (result == VAVCORE_SUCCESS) { // 명시적 비교
LOGI("VavCore initialized successfully");
return JNI_TRUE;
} else {
LOGE("Failed to initialize VavCore (error: %d)", result);
return JNI_FALSE;
}
```
**효과**:
- ✅ 성공적인 초기화를 올바르게 감지
- ✅ 에러 코드 상세 로깅 가능
- ✅ JNI 래퍼의 정확한 상태 보고
### **4. Android 초기화 로직 수정** 🏁
**문제**: 조건부 컴파일 블록 오류로 항상 실패 경로로 진입
**해결책**:
```cpp
// VavCore.cpp - vavcore_initialize() 수정
#ifndef ANDROID
// Windows: DLL 초기화 확인
if (!IsDllReadyForInitialization()) {
return VAVCORE_ERROR_INIT_FAILED;
}
if (!PerformSafeDllInitialization()) {
return VAVCORE_ERROR_INIT_FAILED;
}
#else
// Android: JNI 라이브러리 준비 확인
if (!IsAndroidLibraryReady()) {
__android_log_print(ANDROID_LOG_ERROR, "VavCore", "Android JNI library not ready");
return VAVCORE_ERROR_INIT_FAILED;
}
__android_log_print(ANDROID_LOG_INFO, "VavCore", "Android initialization successful");
#endif
// 공통: 디코더 등록 및 팩토리 초기화
RegisterAV1Decoders();
#ifdef ANDROID
RegisterAndroidMediaCodecDecoders();
#endif
VideoDecoderFactory::InitializeFactory();
```
**효과**:
- ✅ Android 전용 초기화 경로 올바르게 실행
- ✅ 플랫폼별 조건부 컴파일 정상 작동
- ✅ 초기화 성공 시 디코더 등록 정상 진행
---

# Android 16KB 페이지 정렬 및 JNI 라이브러리 통합 프로젝트
**완료일**: 2025년 9월 29일
**목적**: Android 15+ 호환성을 위한 16KB 페이지 정렬 적용 및 VavCore JNI 라이브러리 통합
**상태**: ✅ 완료
---
## 📋 프로젝트 개요
### 🎯 주요 목표
1. **16KB 페이지 정렬 적용**: Google Play 2025년 11월 1일 요구사항 준수
2. **Android 빌드 스크립트 업데이트**: 모든 Android 라이브러리에 16KB 정렬 적용
3. **JNI 라이브러리 통합 문제 해결**: APK 내 libvavcore.so 포함 오류 수정
4. **라이브러리 이름 충돌 해결**: JNI 래퍼와 prebuilt 라이브러리 구분
### 🚨 해결한 주요 문제
- **런타임 오류**: `dlopen failed: library "libvavcore.so" not found`
- **의존성 오류**: `library "libVavCore.so" not found: needed by libvavcore.so`
- **빌드 시스템 통합**: CMakeLists.txt 경로 문제 및 라이브러리 패키징 이슈
- **Google Play 호환성**: Android 15+ 디바이스에서 16KB 페이지 크기 지원
---
## ✅ 완료된 작업 상세
### 1. **16KB 페이지 정렬 적용**
#### 수정된 빌드 스크립트들:
- `build_vavcore_android.bat`
- `build_dav1d_android.bat`
- `build_libwebm_android.bat`
#### 적용된 링커 플래그:
```bash
-Wl,-z,max-page-size=16384
-Wl,-z,common-page-size=16384
```
#### CMake 설정 (VavCore Android):
```cmake
set_target_properties(vavcore_jni PROPERTIES
LINK_FLAGS "-Wl,-z,max-page-size=16384 -Wl,-z,common-page-size=16384"
)
```
#### Meson 설정 (dav1d):
```meson
c_link_args = ['-Wl,-z,max-page-size=16384', '-Wl,-z,common-page-size=16384']
cpp_link_args = ['-Wl,-z,max-page-size=16384', '-Wl,-z,common-page-size=16384']
```
### 2. **Android JNI 라이브러리 통합**
#### CMakeLists.txt 경로 수정:
```cmake
# 수정 전 (잘못된 경로)
set(VAVCORE_LIB_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../../android/vavcore/lib/android-${ANDROID_ABI}")
# 수정 후 (올바른 경로)
set(VAVCORE_LIB_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../../../platforms/android/vavcore/lib/android-${ANDROID_ABI}")
```
#### Include 경로 수정:
```cmake
include_directories(
${CMAKE_CURRENT_SOURCE_DIR}/include
${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../../../platforms/android/vavcore/include
${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../include
${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../include/dav1d
${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../include/libwebm
)
```
### 3. **라이브러리 이름 충돌 해결**
#### 문제:
- JNI 래퍼: `libvavcore.so`
- Prebuilt 라이브러리: `libVavCore.so`
- Windows에서는 대소문자 구분 없어 혼란 발생
#### 해결책:
```cmake
# JNI 래퍼 라이브러리 이름 변경
add_library(vavcore_jni SHARED ${JNI_SOURCES})
```
```java
// Java 코드에서 로드 이름 변경
System.loadLibrary("vavcore_jni");
```
#### 최종 라이브러리 구조:
- **JNI 래퍼**: `libvavcore_jni.so` (1.47MB)
- **Prebuilt 라이브러리**: `libVavCore.so` (2.86MB)
### 4. **자동 라이브러리 복사 설정**
#### CMakeLists.txt POST_BUILD 명령어:
```cmake
# JNI 래퍼 라이브러리 복사
add_custom_command(TARGET vavcore_jni POST_BUILD
COMMAND ${CMAKE_COMMAND} -E make_directory ${CMAKE_CURRENT_SOURCE_DIR}/../jniLibs/${ANDROID_ABI}

# Prebuilt VavCore 라이브러리 복사
if(TARGET VavCore)
add_custom_command(TARGET vavcore_jni POST_BUILD

COMMENT "Copying libVavCore.so to jniLibs/${ANDROID_ABI}/"
)
endif()
```

:: VavCore Android Local Build Script
:: ================================================================================================
:: Purpose: Build VavCore library for Android in local directory
:: Target: vav2/platforms/android/vavcore/lib/
:: Author: Generated with Claude Code
::
:: Prerequisites:
:: 1. Android NDK r25+ installed
:: 2. CMake installed and in PATH
:: 3. Dependencies pre-built in project root lib/ directory
::
:: Usage:
:: 1. Set Android NDK environment variable:
:: set ANDROID_NDK_HOME=C:\Android\android-ndk-r25c
:: 2. Run this script:
:: build_vavcore_android.bat (for ARM64)
:: build_vavcore_android.bat arm32 (for ARM32)
::
:: Output:
:: - vav2/platforms/android/vavcore/lib/android-arm64-v8a/libVavCore.so

🎯 추천하는 다음 작업 순서:
1. 우선순위: AV1 비디오 파일 디코딩 테스트 구현
현재 VavCore 초기화와 디코더 감지까지는 완료되었지만, 실제 비디오 파일을 열고 프레임을 디코딩하는
기능이 필요합니다.
구현 내용:
- VavCore C API를 사용한 실제 WebM/AV1 파일 열기
- 프레임별 디코딩 및 YUV → RGB 변환
- Android에서 디코딩된 프레임 표시
2. MediaCodec vs dav1d 성능 비교
두 디코더의 실제 성능을 측정하여 최적의 선택을 할 수 있도록 벤치마크 구현
3. 실제 비디오 재생 UI 구현
MainActivity의 "Video Player" 버튼에 실제 기능 추가
4. Android 기기 실제 테스트
APK를 실제 Android 기기에 설치하여 하드웨어 가속 테스트
---
어떤 작업부터 시작하시겠습니까?
A) AV1 비디오 파일 디코딩 테스트 - 실제 비디오 파일을 열고 디코딩하는 기능 구현B) 성능 벤치마크 테스트
- MediaCodec와 dav1d 성능 비교C) 비디오 재생 UI - 실제 비디오 플레이어 화면 구현D) Android 기기
테스트 - APK 배포 및 실기기 테스트
또는 다른 우선순위가 있으시면 말씀해 주세요! 🚀
