Directx 9.0c sdk를 이용하여
동영상 플레이어 제작을 하고 있습니다.
거의 마무리 단계에서 LNK 2001 에러가 나오는데..
어찌 해결해야 할지 모르겠습니다.
아래는 에러 코드 입니다.
1MPEG.obj : error LNK2001: _CLSID_DefaultDirectSound 외부 기호를 확인할 수 없습니다.
1MPEG.obj : error LNK2001: _CLSID_MPEGAudioDecoder 외부 기호를 확인할 수 없습니다.
1MPEG.obj : error LNK2001: _CLSID_MPEGVidoeDecoder 외부 기호를 확인할 수 없습니다.MyCLSID.h 라는 헤더 파일을 임포트 시켜서
아래와 같이 추가 했습니다.
