+● 현재 VavCore DLL 통합 테스트가 완전히 완료되었으므로, 다음 단계를 제안합니다:
+
+ 🎯 다음 작업 옵션들
+
+ Option 1: Godot 실제 통합 테스트 (강력 추천)
+
+ - VavCore.Godot 프로젝트에서 실제 AV1 비디오 재생 테스트
+ - GPU Surface 디코딩 vs CPU Fallback 성능 비교
+ - Godot 씬에서 VavCorePlayer 컨트롤 실제 사용
+
+ Option 2: GPU Surface 디코딩 활성화
+
+ - D3D11/Vulkan Surface 디코딩 구현 완성
+ - Zero-Copy GPU 파이프라인 실제 동작 검증
+ - RenderingDevice 텍스처 바인딩 테스트
+
+ Option 3: 성능 벤치마킹 시스템
+
+ - CPU vs GPU 디코딩 성능 측정
+ - 4K AV1 실시간 재생 성능 검증
+ - 메모리 사용량 프로파일링
+
+ Option 4: 크로스 플랫폼 확장
+
+ - Android/iOS 플랫폼 빌드 테스트
+ - MediaCodec/Metal Surface 통합
+ - 플랫폼별 최적화 검증
+
+ Option 5: Unity/Unreal 엔진 통합
+
+ - VavCore C API를 Unity C# 스크립트에 통합
+ - Unreal Engine C++ 플러그인 구현
+ - 다른 게임 엔진 지원 확장
+
+ 어떤 옵션을 선택하시겠습니까? (1-5번 또는 다른 아이디어가 있으시면 말씀해주세요)
+
+---------------------------------------------
+
+ Option B: Godot 프로젝트 통합 및 UI 구성
+
+ 실제 Godot 씬에서 VavCorePlayer 사용 예제 구현
+ - Godot 프로젝트 생성 및 VavCorePlayer 노드 통합
+ - UI 컨트롤 구성 (재생/일시정지/탐색/설정)
+ - 파일 선택 다이얼로그 구현
+ - 실시간 재생 상태 표시 (FPS, 모드, 에러)
+
+ Option C: 예외 처리 및 에러 복구 강화
+
+ 견고한 에러 핸들링 시스템 구축
+ - VavCore 초기화 실패 시 복구 로직
+ - 비디오 로딩 실패 시 사용자 피드백
+ - 디코딩 오류 시 graceful degradation
+ - 메모리 부족 상황 대응
+
+ Option D: 성능 프로파일링 및 벤치마킹
+
+ 체계적인 성능 측정 시스템
+ - 프레임 디코딩 시간 측정
+ - GPU vs CPU 모드 성능 비교
+ - 메모리 사용량 프로파일링
+ - 다양한 해상도별 성능 테스트
+
+ Option E: 플랫폼별 네이티브 최적화
+
+ 각 플랫폼에 특화된 성능 향상
+ - Windows: D3D11 네이티브 Surface 공유 구현
+ - Android: Vulkan/OpenGL ES 최적화
+ - iOS/macOS: Metal 성능 향상
+ - 플랫폼별 빌드 테스트
+
+ 💡 개인적 추천: Option A
+
+ 지금까지 구현한 모든 기능이 이론적으로는 완벽하지만, 실제로 동작하는지 검증이 필요합니다. 특히:
