누락된 종속성을 해결하는 방법은 무엇입니까?
전체 질문:
이것을 실행하면 ffmpeg -i "./input.mp4" -vcodec libvpx-vp9 -acodec libvorbis -b:v 9M "./output.webm"결과 비트 전송률은 9MB가 아니고 훨씬 작아집니다. 하지만 사용하려는 입력 비디오의 비트 전송률은 정확히 9MB 이상입니다.
왜 이런 일이 발생하는지 궁금합니다. 를 사용하는 것 외에는 이 문제를 해결하는 데 도움을 줄 수 있는 방법이 없습니다 -crf. 이렇게 하면 시행착오를 통해 출력 파일의 비트 전송률을 입력 파일의 비트 전송률과 일치시킬 수 있습니다. 이 문제는 다음 질문과 관련이 있을 수도 있고 없을 수도 있습니다. 이에 대해 별도의 질문을 만들어야 할 수도 있습니다.
위의 문제로 인해 ffmpeg를 다시 설치해 보았습니다. ffmpeg가 설치된 것 같습니다.Basil Gello의 Kodi 저장소(메인 데비안 저장소의 Kodi 버전은 매우 오래되었습니다.) 처음에는 저장소를 삭제하고 받은 저장소를 실행하여 sudo apt-get update && sudo apt-get --reinstall install ffmpegffmpeg를 다시 설치해 보았습니다. Reinstallation of ffmpeg is not possible, it cannot be downloaded.그래서 저장소를 다시 추가하고 다음을 실행했습니다 sudo apt-get --reinstall install ffmpeg/buster-backports. 출력은 다음과 같습니다.

누락된 종속성을 해결하는 방법은 무엇입니까? 이것을 다시 설치할 수는 없으며 다른 많은 핵심 패키지가 이에 의존합니다.
나도 달려보려고 했는데sudo apt-get clean ; sudo apt-get update ; sudo apt-get check ; sudo apt-get purge ffmpeg* -y ; sudo apt-get autoremove -y ; sudo apt-get -f satisfy ffmpeg -y 이것문제가 해결되지 않았습니다.
저는 KDE를 사용하여 데비안 10을 실행하고 있습니다. 도움을 주시면 감사하겠습니다.
답변1
libavdevice58 버전 7:4.3.1-6~bpo10+1을 설치하라는 요청이 있었던 것 같습니다. 이는 ffmpeglibavdevice58 버전 7:4.1.6-1~deb10u1에 의존하는 데비안의 바닐라와 충돌합니다 . 명령줄에서 버전을 지정하여 이전 버전을 명시적으로 요청할 수 있습니다.
sudo apt install ffmpeg libavdevice58=7:4.1.6-1~deb10u1
인코딩 결과에 대해서는 두 번째 질문을 해야 합니다. ~처럼관광 가이드함께 작용하는 몇 가지 매개변수가 있음을 지적합니다. 명령은 실제로 인코더를 고정 비트 전송률 모드가 아닌 평균 비트 전송률 모드로 설정합니다. 소스 자료가 충분히 쉽게 압축될 수 있는 경우 인코더는 항상 목표 비트 전송률 미만을 유지하도록 선택할 수 있습니다.
