First of all i have to mention that comping software i am very new to had just compiled ffmpeg and imagic for my Dev MAMP work field. But after got hot with image and video processing software like MLT . I just found the gorgeous branch stills2dv . Zooming probably is not the big thing but how the lib speed and slow up the pans and zooms is the best and most intuitive i have seen. Building the workfile is like writing a Text script how to zoom and Pan . Very simple if you have a bit of feeling for Pans & Zooms .
This stills2dv package have some very sweet Zoom and Pan options for still images but was build for Linux and some outdated lybs and commands made it a bit hard for me compile. for future i will note here what i change to get it work .Last but not least dropped in as i would like huge panorama images and return a video that can be shared on social media platforms like Facebook or Instagram. That as a terminal batch proces without opening any editing software.
Future idea is to create the workfile for pan zoom with a html editor.
First of all watch the video to get a impression what is the still2dv can do
First make sure you have the needed libs Installed
X11 installed
most likely this packages are already on your machine
libc
gcc
make
libjpeg-dev
libpng-dev
Some changes for the PATH to work on OSX below my make file with corrected paths. The only change was in the first lines -lXext and -lX11 made me some trouble till i installed XQuartz .
PREFIX = /usr CC = gcc COPTIONS = -Wall -g -O4 CLIBS = -ljpeg -lpng -lm -I/opt/X11/include -L/opt/X11/lib/ -lXext -lX11 all: stills2dv hash: hash.c stills2dv.h $(CC) -o hash $(COPTIONS) hash.c stills2dv: s2d_main.o s2d_ppm.o s2d_jpg.o s2d_png.o s2d_smoothing.o x_lowlevel.o $(CC) -o stills2dv $(COPTIONS) s2d_smoothing.o s2d_ppm.o s2d_jpg.o s2d_png.o s2d_main.o x_lowlevel.o $(CLIBS) echo You may try the command: make example s2d_main.o: s2d_main.c stills2dv.h $(CC) $(COPTIONS) -c s2d_main.c s2d_jpg.o: s2d_jpg.c stills2dv.h $(CC) $(COPTIONS) -c s2d_jpg.c s2d_png.o: s2d_png.c stills2dv.h $(CC) $(COPTIONS) -c s2d_png.c s2d_ppm.o: s2d_ppm.c stills2dv.h $(CC) $(COPTIONS) -c s2d_ppm.c s2d_smoothing.o: s2d_smoothing.c stills2dv.h $(CC) $(COPTIONS) -c s2d_smoothing.c x_lowlevel.o: x_lowlevel.c $(CC) $(COPTIONS) -c x_lowlevel.c clean: rm -f *.o stills2dv hash Example/out.mpg tmp/* out.mpg tmp.mpg ffmpeg2pass*.log *~ clean_temp: rm -f *.o tmp/* tmp.mpg ffmpeg2pass*.log example: stills2dv mkdir -p tmp rm -f tmp.mpg out.mpg ./stills2dv -tmpdir tmp -showoutput exampleworkfile.s2d ffmpeg -r 30.00 -f image2 -i tmp/%05d.jpg -i example_data_files/09_1_2_3_4.mp3 -vcodec mpeg4 -vb 9000k -ab 128k -aspect 16:9 -pass 1 tmp.avi ffmpeg -r 30.00 -f image2 -i tmp/%05d.jpg -i example_data_files/09_1_2_3_4.mp3 -vcodec mpeg4 -vb 9000k -ab 128k -aspect 16:9 -pass 2 out.avi rm -f tmp/* tmp.avi mplayer out.avi -fs install: stills2dv cp -f stills2dv $(PREFIX)/bin chmod 755 $(PREFIX)/bin/stills2dv chown root:root $(PREFIX)/bin/stills2dv
To run the Install you need also to adapt the install part since root:root doesn’t exist on osx .The install done manually in the terminal
One more change on s2d_png.c since libpng updated some commands will not work. My s2d_png.c following error found on stackoverflow
Chances are you are compiling IM with png.h from libpng-1.5.x but
* Bugs png_longjmp” only exists inlibpng-1.5.x.
* libpng-1.6.17 already installed
changeds2d_png.c to following . Mostly replaced the old format to the new strukture
png_create_info_struct

Now we are at the point that make and sudo make install works without any error.
IMPORTANT
We need XQuartz works fromOS X 10.6.3 till El Capitan , Download and install this part output the images to the window and will get started from the terminal as soon Showoutput get executed.
Run in Terminal
stills2dv -tmpdir tmp -showoutput workfil_pano.s2d
Terminal returns and start prozessing your workfile and place all images in the tmp folder. My workfil_pano is a simple pan from left to right
resolution 1200×830
fps 25
type jpg
img Kaiserpano.jpg zoom FITHEIGHT startpoint LEFT endpoint RIGHT duration 29.00Creating framCreating fCreaCreating frame #00024 at x= 244.22 y= 165.00 and zoom 4.06
After all Zoom Pan prozessed the tmp is full of single images now combine them with ffmpeg to get the final movie
ffmpeg -r 25.00 -f image2 -i tmp/%05d.jpg -i myaudiofile.mp3 -target pal-dvd -s 1920x1080 -vb 9000k outvid.mpg
I hope i dont forget anything , its already some days ago
