다음을 사용하여 소스에서 FFMPEG를 컴파일하고 있습니다.우분투 가이드이전에 성공적으로 사용했던 것입니다.
Ubuntu 서버 14.04의 VirtualBox에서 Vagrant 가상 머신을 컴파일하고 있습니다. 프로젝트와 을 복제하면 vagrant up상자에 FFMPEG가 설치됩니다.github.com/rfkrocktk/vagrant-ffmpeg.
저는 Ansible을 사용하여 컴파일을 자동화하고 있으므로 모든 단계를 볼 수 있습니다.여기:

Ansible을 모르더라도 이것이 무엇을 하는지 명확하게 알 수 있기를 바랍니다.
ffmpeg내가 겪고 있는 문제는 이 모든 작업이 성공적으로 실행된 후에도 컴퓨터 내에서 실행할 때 다음 오류가 발생한다는 것입니다 .
ffmpeg: error while loading shared libraries: libx265.so.77: cannot open shared object file: No such file or directory
파일을 명확하게 찾을 수 있습니다.
$ find /usr -iname libx265.so.77
/usr/local/lib/libx265.so.77
왜 이것이 발견되지 않습니까? 편집 가이드에 뭔가 빠졌나요? 나는 내 바이너리가 인간적으로 가능한 한 이식성이 있기를 바랍니다.

LD_LIBRARY_PATH환경 변수에 정의되어 있지 않습니다.
또한 이것은:
$ grep -r local /etc/ld.so.conf.d/
/etc/ld.so.conf.d/libc.conf:/usr/local/lib
내 작업 이론은 Ansible command모듈이 환경 변수를 제거하기 때문에 모든 것이 중단된다는 것입니다.
FFMPEG 또는 x265 빌드에 문제가 있다고 생각합니다. --enable-libx265FFMPEG 구성 명령을 제거했고 이제 FFMPEG가 작동하고 있습니다.
답변1
내 문제는 모든 것을 설치한 후 실행한 적이 없다는 사실에 있었습니다 ldconfig.
Debian에서 공유 개체 라이브러리를 찾으려면 실행하여 sudo ldconfig공유 라이브러리 캐시를 다시 빌드해야 합니다.
