# Contains non-trivial handling of option variables
# and build environment. Must be included after
# bsd.port.pre.mk

# Some of the knobs are not tunable by the OPTIONS framework. These are
# explained here in detail.

# $FreeBSD$
#
# Feature options:
# These options influence some general behaviour of mplayer. Almost all of the featues,
# for example all the codecs, are selected via the OPTIONS framework.
# The following options WITH_DVD_DEVICE, WITH_CDROM_DEVICE, are *not*
# selected via the options framework and must be set via make.conf or by passing
# the variable to make during build, e.g. make WITH_DVD_DEVICE=/dev/cd0
#
# WITH_DVD_DEVICE=/path/to/desired/device
# default: /dev/cd0
# This option changes the default device where mplayer looks for
# a DVD medium
#
# WITH_CDROM_DEVICE=/path/to/desired/device
# default: /dev/cd0
# This option changes the default cdrom device, maybe useful for VCDs
