the files in the codecs folder you made, i believe, should just be the contents
of the essential-20061022 folder. ill try and make this easier.
lets assume my home folder is /home/me, and i have downloaded this codec file to /home/me/essential-20061022.tar.bz2. open a terminal window and use 'su' to become root, and enter the following commands (double check what you type before pressing enter as root prompt isnt forgiving!!!):
rm -R /usr/local/lib/codecs/essential-20061022
tar jxf essential-20061022.tar.bz2
mv * /usr/local/lib/codecs/
now lets install MPlayer, with the option of having a GUI. lets assume i downloaded the MPlayer source code to my home folder, the file is: /home/me/MPlayer-1.0rc1.tar.bz2. again, at your root prompt run:
tar jxf MPlayer-1.0rc1.tar.bz2
you can now delete this new MPlayer-1.0rc1 folder if you want. to play a file with MPlayer open a terminal and run the command 'mplayer fileName' or look at 'man mplayer' for info on how to use it. to run the GUI, you need to execute 'gmplayer', however you have to set up your skin. to do that read this page
hope it helps
edit: ill try and narrow down what you have to do to install the skin.
after downloading one (here
), extract using a similar 'tar' command as above. then use 'mv' to move the entire folder to the MPlayer skins folder. lets say ive downloaded a skin called 'foo' and the file is /home/me/foo.tar.bz2. at your root terminal run:
tar jxf foo.tar.bz2
mv foo /usr/local/share/mplayer/skins
you have to edit the file /home/me/.mplayer/config and add this line:
substituting the appropriate filenames when necessary, of course.
