Port MiniDLNA to Windows / OS X

I am looking for someone to port the MiniDLNA server program to Windows

and Mac OS X. MiniDLNA is a minimal, open-source DLNA server for Linux. The

goal of this job is to port MiniDLNA so that it can be run and conveniently

used on both OS X and a modern Windows PC (Windows XP and newer). Further

the external dependencies of MiniDLNA should be reduced to simplify the

build process.

You can obtain MiniDLNA from here: [url removed, login to view]

More information on DLNA is here: [url removed, login to view]

The two targets OS X and Windows require a very different amount of work:

OS X is a much closer target to Linux than Windows. And most important: A

working MiniDLNA port to OS X already exists! It just resides in a separate

branch and was not yet integrated into MiniDLNA's main branch.

I therefore propose to tackle the project by the following four sub-steps:

1) Integrate existing OS X port into main branch

The existing MiniDLNA OS X port resides in the "osx_port" development branch.

You can read more about it here:

I'm not sure by how far the osx_port branch is out of sync with the main

branch but it should be ok. Some code of the osx_port branch might be

OS X specific and the build script probably incomplete. See here:

Goal of this first step is to merge the code of the osx_port and the main

branch as well as update the build scripts so that MiniDLNA can be compiled

out of the box on both Linux and OS X from one code base.

2) Windows CLI port

MiniDLNA can run as a daemon under Linux or as a normal command-line

application (for debug purposes). In this first step, the MiniDLNA server

just needs to properly run in application-mode on Windows - not as a


MiniDLNA's makefile and build scripts should be extended so that they also

support a MinGW target and the MiniDLNA CLI application becomes compilable

for win32 target using MinGW compiler.

Preliminary analysis indicates that the major hurdle to achieve the initial

Windows port should be the inotify syscall()'s used in the MiniDLNA source

code. This functionality must be re-implemented using the Windows

ReadDirectoryChangesW API.

3) Porting to Windows Service

Implement the MiniDLNA server as a Windows Service: Just as MiniDLNA can

be started as a deamon under Linux the windows port should also run as a

windows service. In addition, there should be the possibility to check the

status or start/stop/restart the MiniDLNA server either via a tray icon or

shortcuts under Start->Programs menu.

Because MiniDLNA is an open-source program under GPL license you could

reuse code from other GPLed programs that run as Windows Service. There

are several such open-source projects that seem to use code derived from

sample code in the Windows Platform SDK.

4) Trim down external dependencies

In the source file "metadata.c", MiniDLNA parses input media files for meta

data like title, artist or playback duration. MiniDLNA requires a rather

large number of external libraries for this task like libjpeg, libid3tag,

libexif, libavformat and libavcodec. Especially, libavformat and libavcodec

are full-featured (and large!) container muxing/demuxing and video/audio de-

and encoder libraries. MiniDLNA however doesn't use any de- or encoding

functionality at all.

Therefore, the meta data parsing in "metadata.c" should be changed to

interface with libmediainfo, which provides the necessary functionality:

At least the references to libavformat and libavcodec should be replaced

by libmediainfo. However, libmediainfo has potential to replace also other

dependencies (like libid3tag, libjpeg, libvorbis, etc.). So the goal of this

step is to reduce the number of external dependencies as much as

reasonably possible.

Please only bid if you have read and understood the project description!

As there seems to be common misunderstanding: The OS X port of MiniDLNA already exists and it is functional. So I don't expect any further work on the existing OS X code. Just MiniDLNA for OS X and MiniDLNA for Linux currently reside in two distinct code branches. The task of this project is to merge the branches into one code base. This should actually represent just a minor fraction of the total complexity of the project.

Also note that the integration of the existing OS X code is of minor importance to me. So if you refrained from considering this project so far because you have only experience with Windows but not with OS X this shouldn't prevent you from bidding. If you are otherwise convincing we can drop the OS X requirement and you have good chances to be awarded with the project.

And with regard to the skills you should have: MiniDLNA is a program written in C language and using some lower-level interfaces (like inotify). So this is not about scripting! Therefore, I expect that you at least have skills in C programming...

Meanwhile, MiniDLNA has been ported to Windows using Cygwin. The patches are available upstream at:

This should significantly simplify this project - especially Task 2). Please consider.
