# If you installed the codecs package according to the instructions at
# the MPlayer website, you'll probably want to change this variable
# to /usr/local/lib/codecs.  Otherwise, you'll want to leave it alone
# (if you installed the codecs using our SlackBuild script for them)

# The default MPlayer theme is Blue
# http://www.mplayerhq.hu/MPlayer/skins/Blue-1.7.tar.bz2
# Others may work fine here, but the script has not been tested with them
# Even so, it's probably better to leave this alone and install additional
# themes to $HOME/.mplayer/skins/
THEME=Blue
THEME_VERSION=1.7

# The fonts listed below should exist on a stock Slackware 11.0 system.
# If you want to change the default font after installation, that is probably 
# best done by making a link to your preferred font in $HOME/.mplayer/ by:
#   cd $HOME/.mplayer
#   ln -s /path/to/preferred/font subfont.ttf 
OSDFONTS="Arialuni.ttf arial.ttf DejaVuSans.ttf Vera.ttf"

# This will build documentation for all languages - if you don't want some
# of the, either change this or pass what you do want on the command line
# when running the script:  LANGUAGES=en ./MPlayer.SlackBuild
