make latex media files

# Makefile to convert media files to formats usable
# by pdfletex and beamer

.PHONY: videos figures clean all

## Target files ##
# collect media files in current directory:
epsFiles := $(wildcard *.eps)
svgFiles := $(wildcard *.svg)
aviFiles := $(wildcard *.avi)
# replace original file extensions with target extension
epsFiles := $(patsubst %.eps,%.pdf,$(epsFiles))
svgFiles := $(patsubst %.svg,%.pdf,$(svgFiles))
aviFiles := $(patsubst %.avi,%.mp4,$(aviFiles))

## Figures ##
figures: $(epsFiles) $(svgFiles)

%.pdf: %.eps
	epstopdf $<
	
%.pdf: %.svg
	inkscape -A $*.pdf $*.svg

## Videos ## (mp4 files are required by the media9 package for beamer)
videos: $(aviFiles)

%.mp4: %.avi
	avconv -i $*.avi -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -c:v libx264 $*.mp4

## Main rule for the project, for example:
all: figures videos

#TODO "make clean" target 
# cleanup routine (carefull for files that have no other source than pdf!)
