I would temporarily disable both and use the atrpms for mplayer.
Create a file /etc/yum/repos.d/atrpms
- Code: Select all
name=CentOS6 $releasever - $basearch - ATrpms
You should look at the wiki articles for various repos. http://wiki.centos.org/AdditionalResources/Repositories
I'm finding that the atrpms repo has the more current versions of most multimedia programs so have been using it.
EPEL has some library versions that clash with the others.
If using atrpms, I would use the line
yum --disablerepo=epel-* install mplayer
(There's also some el6 ones on their site, but the above works well for me.)
