FFMPEG를 사용하여 DVD에서 VOB 파일을 자동으로 연결(병합)하는 데 문제가 있습니다.

Question

많은 실험과 연구 끝에 BAT 파일 스크립트를 만들어 변수에 두 번째 BAT 파일 스크립트를 작성하고 임시 BAt 파일로 저장하는 것이 가장 좋은 방법이라는 것을 알았습니다. 그런 다음 구성된 BAT 파일은 원하는 DVD 타이틀 세트와 타이틀 세트에서 검색된 파일 수를 기반으로 사용자 정의 구성된 "concat: " 매개변수를 사용하여 빌드할 수 있습니다. 연고의 유일한 문제점은 파이프(|) 문자가 포함된 변수에 문자열을 작성하는 것이 거의 불가능하다는 것입니다. 저는 빌드 중에 '@' 문자를 대체하여 이 문제를 해결했고 나중에 오픈 소스 파일 검색 및 교체 유틸리티를 사용하여 '@' 인스턴스를 "|"로 변경했습니다. 잘 작동합니다. 참고 저는 2020년 6월에 다운로드하여 설치된 Windows 10 및 FFMPEG 버전 git-2020-06-26-7447045를 사용하고 있습니다. 아래는 제가 만든 주석 처리된 배치 파일입니다. 비슷한 작업을 원하는 사람이 있으면 이 파일로 시작할 수 있습니다. 개선될 수 있다는 것을 알고 있지만 작동합니다(항상 좋은 시작입니다)!
