[CentOS] Multimedia codecs

The following steps will use yum to install all the packages needed to have full multimedia support. Note there will be a lot of dependencies.

yum install compat-libstdc++-33 libdvdcss libdvdread libdvdplay libdvdnav lsdvd libquicktime
 

yum install flash-plugin mplayerplug-in mplayer mplayer-gui gstreamer-ffmpeg gstreamer-plugins-bad gstreamer-plugins-ugly

Install the w32Codecs. (Required for xvid and other proprietary formats.)

wget www1.mplayerhq.hu/MPlayer/releases/codecs/mplayer-codecs-20061022-1.i386.rpm 

rpm -ivh mplayer-codecs-20061022-1.i386.rpm 

wget www1.mplayerhq.hu/MPlayer/releases/codecs/mplayer-codecs-extra-20061022-1.i386.rpm 
rpm -ivh mplayer-codecs-extra-20061022-1.i386.rpm


You should now have full multimedia and video support for most popular formats.
