# -- PATENT ALERT! --
# MPLayer can be built with AMR audio encoders
# (needed for FLV and .3GP videos) but these libraries are 'contaminated'
# with patents from 3GPP.
# Also, the AAC encoder has patent issues.
# You can build these patended algorithms into ffmpeg, and if you are an
# ordinary end user, no one will bother you for using them.
# For the binaries based on this SlackBuild that I distribute, it is a
# different story. I am not allowed to distribute binary packages that
# incorporate patented code. So here you go. My Slackware package was
# built with "USE_PATENTS=NO" i.e. without using
# the faac, AMR and dvdcss libraries.
# ---------------------------------------------------------------------------
USE_PATENTS=${USE_PATENTS:-"NO"}

# MPlayer will try to use one of the TrueType fonts present on the target
# system for it's On Screen Display (OSD) font.
# Slackware 11.0 ships with the Vera and DejaVu fonts, you may want to add
# more fonts to this list. The first font found will be used by creating a
# symbolic link "/usr/share/mplayer/subfont.ttf" to it.
# The use of bitmapped fonts is considered deprecated, but you can still use
# those if you want. Read http://www.mplayerhq.hu/DOCS/HTML/en/fonts-osd.html
# if you want to know more about OSD font configuration.
