Windows 용 decklink 형식 (-f decklink)을 지원 하는 최신 정적 ffmpeg 빌드 를 다운로드했습니다
.
또한 decklink 10.8.2 드라이버를 설치 했습니다 (이 빌드가 게시 될 때 사용 가능한 최신 드라이버 임)
데크 링크 장치를 참조하십시오 :

첫 번째 장치에서 지원되는 형식은 다음과 같습니다.
ffmpeg -f lavfi -t 1 -i nullsrc -f decklink -list_formats 1 “DeckLink SDI (1)”

그러나 작은 따옴표로는 작동하지 않습니다 (아마도 중요합니다).
ffmpeg -f lavfi -t 1 -i nullsrc -f decklink -list_formats 1 ‘DeckLink SDI (1)’

다음 오류가 발생했습니다. “출력 파일 # 0에 헤더를 쓸 수 없습니다 (잘못된 코덱 매개 변수?) : 해당 장치 나 주소가 없습니다”
누군가이 오류의 원인과 해결 방법을 설명해 주시겠습니까?
