No se encontró el espejo al intentar instalar FFMPEG en CENTOS7

Estoy en un servidor dedicado con acceso Root. No estoy familiarizado con los servidores. Estoy intentando instalar FFMpeg en mi servidor. Recibo errores y no sé cómo solucionarlos. Así que cualquier luz sobre esto será muy apreciada.

[root@ns335004 ~]# yum update

 One of the configured repositories failed (DAG RPM Repository),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Disable the repository, so yum won't use it by default. Yum will then
        just ignore the repository until you permanently enable it again or use
        --enablerepo for temporary usage:

            yum-config-manager --disable dag

     4. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=dag.skip_if_unavailable=true

failure: repodata/repomd.xml from dag: [Errno 256] No more mirrors to try.

También probé:

sudo yum clean metadata
sudo yum clean all

Pero sigo teniendo el mismo error 404.

Gracias.

Ese es el antiguo repositorio DAG, que está esencialmente obsoleto. Debe eliminarlo, ya sea eliminando el paquete de instalación del repositorio que instaló originalmente o estableciendo enabled=0el archivo del repositorio en /etc/yum.repos.d.

El repositorio EL7 enATrpmstienecompilaciones de FFmpeg. Son bastante antiguos, pero probablemente sean adecuados para la mayoría de los propósitos.

Si quieres lo último y lo mejor, es posible que tengas que hacerlo.construirlo desde la fuente. No es especialmente difícil estos días.
