JarCastingtagtraum FFmpeg package
The tagtraum FFmpeg package is a binary release of some of the libraries released by the FFmpeg project. Its purpose is to provide easy access to Windows and OS X binaries and sources for decoding audio via a Maven repository.
Thus it serves as an upstream project for Java JNI projects wishing to interface with the native libraries. Codecs with known patent problems are disabled (but can be enabled, see below). However, this obviously is no guarantee.
Also, as the focus lies on decoding audio, most encoders are disabled.
This distribution comes with absolutely no support, warranty etc. you name it.

Build
Currently you can only build this library on OS X.
To do so, you also need:
- Maven 3.0.5, http://maven.apache.org/
- a MinGW-w64 crosscompiler, http://mingw-w64.sourceforge.net/, e.g. via MacPorts
- Apple Command Line Tools, available via https://developer.apple.com/, or XCode, https://developer.apple.com/xcode/
- a JDK (to run Maven)
Once you have all this, you need to adjust some properties in the parent pom.xml. Or.. simply override them using -Dname=value notation. E.g. to build with another version of zlib, add
-Dzlib.version=1.2.7
to your mvn call. If you didn't add the bin folder of your crosscompiler to the PATH, you might also want to set -Dmingw.i386.path=... and -Dmingw.x86_64.path=...
If you would like to change the FFmpeg configuration, add
"-Dffmpeg.configure=--enable-static --disable-programs ... "
Note that you need to add quotes around the entire -D parameter to allow for spaces in the value part.
