#
# Makefile for a Video Disk Recorder plugin
#

# 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 = vaapidevice

### Configuration (edit this for your needs)

#CONFIG := -DDEBUG			# enable debug output+functions
CONFIG += -DAV_INFO -DAV_INFO_TIME=3000	# info/debug a/v sync

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

VERSION = $(shell grep 'static const char \*const VERSION *=' $(PLUGIN).cpp | awk '{ print $$7 }' | sed -e 's/[";]//g')
GIT_REV = $(shell git describe --always 2>/dev/null)

### The directory environment:

# Use package data if installed...otherwise assume we're under the VDR source directory:
PKGCFG = $(if $(VDRDIR),$(shell pkg-config --variable=$(1) $(VDRDIR)/vdr.pc),$(shell PKG_CONFIG_PATH="$$PKG_CONFIG_PATH:../../.." pkg-config --variable=$(1) vdr))
LIBDIR = $(call PKGCFG,libdir)
LOCDIR = $(call PKGCFG,locdir)
PLGCFG = $(call PKGCFG,plgcfg)
#
TMPDIR ?= /tmp

### The compiler options:

export CFLAGS	= $(call PKGCFG,cflags)
export CXXFLAGS = $(call PKGCFG,cxxflags)

ifeq ($(CFLAGS),)
$(warning CFLAGS not set)
endif
ifeq ($(CXXFLAGS),)
$(warning CXXFLAGS not set)
endif

_CFLAGS += $(shell pkg-config --cflags alsa libva libavcodec libswscale libswresample x11 x11-xcb xcb xcb-icccm xcb-screensaver xcb-dpms)
LIBS += -lrt $(shell pkg-config --libs alsa libva libavcodec libswscale libswresample x11 x11-xcb xcb xcb-icccm xcb-screensaver xcb-dpms)

### The version number of VDR's plugin API:

APIVERSION = $(call PKGCFG,apiversion)

### Allow user defined options to overwrite defaults:

-include $(PLGCFG)

### The name of the distribution archive:

ARCHIVE = $(PLUGIN)-$(VERSION)
PACKAGE = vdr-$(ARCHIVE)

### The name of the shared object file:

SOFILE = libvdr-$(PLUGIN).so

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

INCLUDES +=

DEFINES += -DPLUGIN_NAME_I18N='"$(PLUGIN)"' -D_GNU_SOURCE $(CONFIG) \
	$(if $(GIT_REV), -DGIT_REV='"$(GIT_REV)"')

### Make it standard

override CXXFLAGS += $(_CFLAGS) $(DEFINES) $(INCLUDES) \
    -g -W -Wall -Wextra -Winit-self -Werror=overloaded-virtual -Wno-unused-parameter
override CFLAGS	  += $(_CFLAGS) $(DEFINES) $(INCLUDES) \

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

OBJS = $(PLUGIN).o vaapidev.o video.o audio.o codec.o ringbuffer.o

SRCS = $(wildcard $(OBJS:.o=.c)) $(PLUGIN).cpp

### The main target:
