[CentOS] Re Centos 7.2 Repos

Hi All,
I am having a terrible time installing multi media tools
like smplayer (which requires mplayer), which is not avaiable
from the centos repos.
I have installed epel.repo which containa the epel-release repo info
for yum
Still I cannot install many things.
For example, I ran
for i in faad2-libs liba52.so.0 libaa.so.1 libartsc.so.0 libass.so.4 
libaudio.so.2 libavcodec.so.53 libavcodec.so.53 libavformat.so.53 
libavformat.so.53 libavutil.so.51 libavutil.so.51 
libBasicUsageEnvironment.so.0 libbluray.so.0 libbs2b.so.0 libcaca.so.0 
libcdio_cdda.so.0 libcdio_cdda.so.0 libcdio_paranoia.so.0 
libcdio_paranoia.so.0 libcdio.so.10 libdca.so.0 libdirac_decoder.so.0 
libdirac_encoder.so.0 libdirectfb-1.7.so.4 libenca.so.0 libesd.so.0 
libfaac.so.0 libfaad.so.2 libgroupsock.so.0 libjack.so.0 
liblirc_client.so.0 libliveMedia.so.0 libmad.so.0 libmp3lame.so.0 
libmpeg2.so.0 libmpg123.so.0 libnemesi.so.1 libopenal.so.1 
libopencore-amrnb.so.0 libopencore-amrwb.so.0 libportaudio.so.2 
libpostproc.so.52 libpostproc.so.52 librtmp.so.0 
libschroedinger-1.0.so.0 libswscale.so.2 libswscale.so.2 libtwolame.so.0 
libUsageEnvironment.so.0 libvga.so.1 libx264.so.120 libx264.so.142 
libxmms.so.1 libxvidcore.so.4 mencoder mplayer-fonts mplayer-skins ; do

yum provides $i
done

It found no match for any of these which required for installing:
yum install mplayer-common-1.1-33.20150505svn.el7.nux.x86_64.rpm

So, please, if you have safe and reliable repos for linux MM tools, 
please share.
