Estou compilando o FFMPEG da fonte usandoo guia para Ubuntuque usei antes com sucesso.
Estou compilando em uma máquina virtual Vagrant no VirtualBox no servidor Ubuntu 14.04. Você pode clonar o projeto vagrant upe o FFMPEG instalado na caixa:github.com/rfkrocktk/vagrant-ffmpeg.
Estou usando o Ansible para automatizar a compilação, para que você possa ver todas as etapasaqui:

Esperançosamente, mesmo que você não conheça o Ansible, deve ficar claro o que ele está fazendo.
O problema que estou tendo é que mesmo depois de tudo rodar com sucesso, quando executo ffmpegde dentro da máquina, recebo o seguinte erro:
ffmpeg: error while loading shared libraries: libx265.so.77: cannot open shared object file: No such file or directory
Posso encontrar claramente o arquivo:
$ find /usr -iname libx265.so.77
/usr/local/lib/libx265.so.77
Por que isso não está sendo encontrado? Estou faltando alguma coisa no guia de compilação? Gostaria que meus binários fossem tão portáteis quanto humanamente possível.

LD_LIBRARY_PATHé indefinido em variáveis de ambiente.
Também isto:
$ grep -r local /etc/ld.so.conf.d/
/etc/ld.so.conf.d/libc.conf:/usr/local/lib
Minha teoria de trabalho é que, como o commandmódulo Ansible elimina variáveis de ambiente, tudo quebra.
Estou pensando que há algo errado com a compilação FFMPEG ou x265. Eu removi --enable-libx265o comando de configuração do FFMPEG e agora tenho um FFMPEG funcionando.

Meu problema era que nunca corri ldconfigdepois de instalar tudo.
Para que bibliotecas de objetos compartilhados sejam encontradas no Debian, você deve executar sudo ldconfigpara reconstruir o cache da biblioteca compartilhada.
