I am using Trixbox (AAH) which runs on Centos. I need to install mplayer, but I am a new user to Linux. I do not have a GUI front end so I just have command line access. The reason I would like to download it is I want to be able to stream an mms:// file from an extension in Trixbox (Asterisk@Home). If someone could detail out the steps how to do this and any codecs which might be needed and how to install those.
