나는 ffmpeg 전문가가 아닙니다. 시네마그래프 효과를 만들기 위해 일치하는 이미지가 위에 겹쳐진 비디오를 생성하려고 합니다. 기본 테스트를 위해 이것을 실행했지만 출력 비디오 끝이 완료되기 약 1.5초 전에 프레임 생성이 중지됩니다.
ffmpeg -ss 10.0000 -t 15.00000 -i waterfall.mp4 -loop 1 -i output.png -an output1.mp4
왜 이런 일이 발생할 수 있는지에 대한 올바른 방향을 알려줄 수 있는 사람이 있습니까? 모든 도움에 감사드립니다!
전체 콘솔 출력은 다음과 같습니다.
