Calling GStreamer from within Java. Applications using gstreamer-java can bind to GStreamer by adding the following startup code, e.g. in main():

if (com.sun.jna.Platform.isMac()) {
   final String jnaLibraryPath = System.getProperty("jna.library.path");
   final StringBuilder newJnaLibraryPath = new StringBuilder(jnaLibraryPath != null ? (jnaLibraryPath + ":") : "");
   newJnaLibraryPath.append("/System/Library/Frameworks/GStreamer.framework/Versions/0.10-" + (com.sun.jna.Platform.is64Bit() ? "x64" : "i386") + "/lib:");
   System.setProperty("jna.library.path", newJnaLibraryPath.toString());
}

Instructions for building the installer package

GStreamer was built separately for 32-bit and 64-bit platforms due to problems with the source code for GStreamer that prevented the --with-universal-archs setting from being used.

1. Download, compile and install a 32-bit version of GStreamer using MacPorts.

(a) Install MacPorts from source:

./configure --build=i386 --prefix=/System/Library/Frameworks/GStreamer.framework/Versions/0.10.29-i386
make
make install


(b) (Optional.) Add a local mirror to /System/Library/Frameworks/GStreamer.framework/Versions/0.10.29-i386/etc/macports/sources.conf to speed up the package downloading process.

(c) Install GStreamer using MacPorts:

sudo port install gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-ffmpeg gnonlin

Note: You may encounter some errors when compiling for 32-bit mode in Snow Leopard. See Andres Colubri's directions for workarounds.

2. Remove the MacPorts files that are not required in the GStreamer binary distribution.

(a) Delete (or temporarily relocate) all of the folders in /System/Library/Frameworks/GStreamer.framework/Versions/0.10.29-i386 EXCEPT the folders bin, include, lib, and libexec, and share.

(b) Delete (or temporarily relocate) all of the files in /System/Library/Frameworks/GStreamer.framework/Versions/0.10.29-i386/bin EXCEPT the gst-* files.

(c) Delete (or temporarily relocate) all of the files in /System/Library/Frameworks/GStreamer.framework/Versions/0.10.29-i386/libexec EXCEPT the libexec/gstreamer-0.10/ files.

(d) Delete (or temporarily relocate) all of the files in /System/Library/Frameworks/GStreamer.framework/Versions/0.10.29-i386/share EXCEPT the share/gstreamer-0.10/ files.

3. Repeat the above steps for the 64-bit build of GStreamer.

(a) Install MacPorts from source:

./configure --build=x86_64 --prefix=/System/Library/Frameworks/GStreamer.framework/Versions/0.10.29-x64
make
make install


(b) Install GStreamer using MacPorts as above in Step 1.

(c) Delete the unnecessary files as in Step 2.

4. Create symlinks to this version of GStreamer:

cd /System/Library/Frameworks/GStreamer.framework/Versions
sudo ln -Ffs 0.10.29-i386 0.10-i386
sudo ln -Ffs 0.10.29-x64 0.10-x64

sudo ln -Ffs 0.10.29-i386 0.10
sudo ln -Ffs 0.10 Current

cd 0.10.29-i386
sudo ln -Ffs lib Library
sudo ln -Ffs bin Commands
sudo ln -Ffs include Headers

cd ../0.10.29-x64
sudo ln -Ffs lib Library
sudo ln -Ffs bin Commands
sudo ln -Ffs include Headers

sudo ln -Ffs /System/Library/Frameworks/GStreamer.framework/Versions/Current/Commands/gst-feedback-0.10 /usr/bin/gst-feedback
sudo ln -Ffs /System/Library/Frameworks/GStreamer.framework/Versions/Current/Commands/gst-inspect-0.10 /usr/bin/gst-inspect
sudo ln -Ffs /System/Library/Frameworks/GStreamer.framework/Versions/Current/Commands/gst-launch-0.10 /usr/bin/gst-launch
sudo ln -Ffs /System/Library/Frameworks/GStreamer.framework/Versions/Current/Commands/gst-typefind-0.10 /usr/bin/gst-typefind
sudo ln -Ffs /System/Library/Frameworks/GStreamer.framework/Versions/Current/Commands/gst-visualise-0.10 /usr/bin/gst-visualise
sudo ln -Ffs /System/Library/Frameworks/GStreamer.framework/Versions/Current/Commands/gst-xmlinspect-0.10 /usr/bin/gst-xmlinspect
sudo ln -Ffs /System/Library/Frameworks/GStreamer.framework/Versions/Current/Commands/gst-xmllaunch-0.10 /usr/bin/gst-xmllaunch


5. Use the XCode PackageMaker tool (located in /Developer/Applications/Utilities/PackageMaker) to create an installer package that includes the /System/Library/Frameworks/GStreamer.framework tree, along with the /usr/bin symlinks created in the previous step. This package is approximately 150 MB for GStreamer 0.10.29 (including both the 32-bit and 64-bit versions).
