sturmflut's Introduction

Sturmflut

Sturmflut is a very fast pixelflut client with full IPv6 support written entirely in C. It can handle both ordinary image files and animations.

Compiling

Dependencies

pkg-config
pthread
ImageMagick
MagickWand

On debian-based systems all required dependencies can be installed using

apt-get install build-essential pkg-config libmagick++-dev libmagickwand-dev

Use make.

Usage

./sturmflut <host> [file to send] [-p <port>] [-a <source ip address>] [-i <0|1>] [-t <number of threads>] [-m] [-o <offset-spec>] [-O] [-s <percentage>] [-S] [-h]

host: IP address of pixelflut server
file to send: Image/Animation to show

-p: Server port
-i: Ignore broken broken pipe
-t: Number of threads used for flooding
-m: Monochrome mode (send only 0|1 instead of RRGGBBAA)
-o: Offset at which to draw, format: <x-offset>:<y-offset>
-O: Optimize animations, send only pixels that have changed between frames
-s: Sparse mode, send only <percentage> of pixels
-S: Data saver mode, transmit every frame of an animation only once instead of flooding it
-h: Show usage

Example

./sturmflut 127.0.0.1 animation.gif

Errors compiling Sturmflut

Quick rundown of what i tried:

CentOS, Fedora, Ubuntu and Debian
Always running into the exact same Magickwand error
Tried numerous versions of Imagemagick from both their website and repo's
Tried removing version check

Nothing helped. Am i doing something wrong?

rm -f sturmflut /bin/sh: 1: pkg-config: not found gcc -Ofast -Wall -march=native -DIMAGICK= image.c network.c main.c progress.c -lpthread pkg-config --cflags --libs MagickWand-o sturmflut /bin/sh: 1: pkg-config: not found In file included from image.c:9: image.h:6:13: error: operator '<' has no left operand #if IMAGICK < 7 ^ image.h:9:11: fatal error: MagickWand/MagickWand.h: No such file or directory #include <MagickWand/MagickWand.h> ^~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated.

Global Offfsets for Images

If contained in the data.txt the Offset should be pushed over each connection first

Some flags are not implemented

Documentation talks about -a flag for source ip address, but this is not implemented

Compiling-Instructions for macos

Not really an issue, because I found the solution, but when trying to build on MacOS, the build failes, because MacOS doesn't have sys/sendfile.h.

I was still able to compile sturmflut aufter replacing sys/sendfile.hwith importing sys/types.h, sys/socket.h and sys/uio.h.
I haven't looked much into the code, so I don't know which of those three are really necessary, but it does work on MacOS now.

UDP support

Does this utility support pixelflut over UDP?
