FFmpeg : strftime을 사용하여 프레임 파일 이름을 가져올 수 없습니다.

Question

FFmpeg에서 생성 한 JPEG 파일에 타임 스탬프를 갖고 싶습니다.

ffmpeg -f dshow -framerate 50 -i video="XI100DUSB-HDMI Video" -strftime 1 "%Y-%m-%d_%H-%M-%S_thumb%04d.jpg" 

또한 말한다 :

av_interleaved_write_frame() : 잘못된 인수 내가 잘못 뭐하는 거지

나는 이런 식으로는 FFmpeg를 실행 위의 오류 메시지를 받고 있어요? 감사합니다.

Answer 1

패턴은 % D 날짜에 예약하고, 확장() STRFTIME에 전달되고있다. Advanced Renamer과 같은 다른 도구를 사용하여 시퀀스 색인 숫자를 접미사로 추가해야합니다.

P. FFmpeg가 프레임을 삭제합니다. 추가 -rtbufsize 20M 전에 -i video
