Por que não consigo instalar o ffmpeg no CentOS 7

Question

Eu quero instalar o ffmpeg no meu servidor do CentOS 7, mas não posso dizer que faltam algumas bibliotecas que não posso encontrar onde e como instalá-las.

Este é o comando que eu usei e o erro ocorreu:

[root@www13 ~]# yum install ffmpeg -y

Onde e como posso instalar o libudev, libopenal, libass para o meu servidor?

Editar: basta executar o comando @Alexander T disse:

Answer 1

Você faz tudo certo, como disse @Bert, mas essas bibliotecas devem ser instaladas a partir do repositório EPEL. Você pode instalá-lo pelo comando yum install epel-release e, depois disso, os erros de dependência desaparecerão.

Aqui lista de pacotes que instala de EPEL (filtrada yum output):

Answer 2

Instale o repositório nux-dextop e execute o yum install ffmpeg
