# You can change the compile options here or create a Make.config
# in the VDR directory an set them there.
#
### uncomment the following line, if you don't want to use swscale functions
### for scaling and color format conversions. Then deprecated img_convert and
### img_resample will be used instead.
#WITHOUT_SWSCALE=1
#
### uncomment the following line, if you have a recent FFMPEG version that
### has a changed structure of its header files.
#WITH_NEW_FFMPEG_HEADERS=1

# 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.

### 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 ?= -g -O2 -Wall -Woverloaded-virtual

### The directory environment:

DVBDIR = ../../../../DVB
FFMDIR = ../../../../ffmpeg-0.4.8
VDRDIR = ../../..
LIBDIR = ../../lib
TMPDIR = /tmp

### Allow user defined options to overwrite defaults:

-include $(VDRDIR)/Make.config

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

APIVERSION = $(shell grep 'define APIVERSION ' $(VDRDIR)/config.h | awk '{ print $$3 }' | sed -e 's/"//g')

### The name of the distribution archive:

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