# The official name of this plugin.
# This name will be used in the '-P...' option of VDR to load the plugin.
# By default the main source file also carries this name.
#
PLUGIN = dxr3

### The version number of this plugin (taken from the main source file):

VERSION = $(shell grep 'static const char VERSION\[\] *=' $(PLUGIN).c | awk '{ print $$6 }' | sed -e 's/[";]//g')

### The C++ compiler and options:

CXX      = g++
CXXFLAGS = -O2 -fPIC -Wall -Woverloaded-virtual

### The directory environment:

VDRDIR = ../../..
LIBDIR = ../../lib
TMPDIR = /tmp

# Usually something like -I/path/to/ffmpeg, should work as is if FFmpeg was
# installed properly and pkg-config is available.
FFMPEG_INC = $(shell pkg-config --cflags-only-I libavcodec)

# Usually something like -L/path/to/ffmpeg/libavcodec -lavcodec, should work
# as is if FFmpeg was installed properly and pkg-config is available.
FFMPEG_LIBS = $(shell pkg-config --libs libavcodec)

ALSA_INC = $(shell pkg-config --cflags-only-I alsa)
ALSA_LIBS = $(shell pkg-config --libs alsa)

# Usually something like -I/path/to/em8300/include,should work as is (empty)
# if em8300 headers were installed properly.
EM8300_INC = 

### Allow user defined options to overwrite defaults:

-include $(VDRDIR)/Make.config

### The version number of VDR's plugin API (taken from VDR's "config.h"):

APIVERSION = $(shell sed -ne '/define APIVERSION/s/^.*"\(.*\)".*$$/\1/p' $(VDRDIR)/config.h)

### The name of the distribution archive:

ARCHIVE = $(PLUGIN)-$(VERSION)
PACKAGE = $(shell echo vdr-$(ARCHIVE) | sed -e 's/git$$/git'`date +%Y%m%d`/)

### Includes and Defines (add further entries here):

INCLUDES += -I$(VDRDIR)/include $(FFMPEG_INC) $(EM8300_INC) $(ALSA_INC)
LIBS      = $(FFMPEG_LIBS) $(ALSA_LIBS)
DEFINES  += -DPLUGIN_NAME_I18N='"$(PLUGIN)"'
DEFINES  += -D_GNU_SOURCE

# where is the microcode for the dxr3 located?  em8300 driver version 0.15.2
# and later installs it by default to /lib/firmware/em8300.bin, and earlier
# versions to /usr/share/misc/em8300.uc.
DEFINES += -DMICROCODE=\"/lib/firmware/em8300.bin\"

# use OSD scaler borrowed from the Xine plugin?
# comment this out to use the traditional vdr-dxr3 scaler
DEFINES += -DUSE_XINE_SCALER

### The object files (add further files here):

OBJS = $(PLUGIN).o dxr3multichannelaudio.o dxr3sysclock.o dxr3colormanager.o \
