We recently installed CentOS 7 from DVD.  Our install selection was the GNOME desktop option. yum update yielded about 465 megabytes of updates all of which were successful with no warnings.  The multi media option was not chosen because KDE was listed. GNOME was not apparent in the software list for the multi media workstation install.

Google searches led us to instructions for installing mplayer.  The repo update appears to be successful as indicated below. Dependency resolution at the time of mplayer installation yielded twelve errors.

Are there other packages that could be installed prior to another attempt at mplayer installation that might provide the missing items?  Might these errors have been avoided by choosing the multi media workstation install?

Thanks.

 You could try using –skip-broken to work around the problem
 You could try running: rpm -Va –nofiles –nodigest
