- [x] 빌드 시스템 통합 (debug 라이브러리 호환성 해결)
- [x] VSTest 실행 환경 구축
#### **🔥 현재 상황: AV1 디코딩 문제 해결 필요** (최고 우선순위)
- **핵심 문제**: AV1 디코더 초기화는 성공하지만 실제 프레임 디코딩이 실패
- **증상**: "Frame 0: decode failed" - 모든 프레임에서 디코딩 실패
- **영향**: 기본 비디오 재생 기능 작동 불가
#### **✅ NVDEC 하드웨어 가속 디코더 구현 완료** (2025-09-24 완료)
- [x] NVIDIA Video Codec SDK 13.0 통합 및 CUDA 13.0 API 지원
- [x] NVDECAV1Decoder 헤드리스 구현 및 테스트 완료
- [x] GUI 프로젝트 NVDEC 통합 및 TIMECODE 충돌 해결
- [x] VideoDecoderFactory에서 NVDEC → MediaFoundation → dav1d 우선순위 설정
- [x] 하드웨어 가용성 자동 감지 및 graceful fallback 구현
