This page explains how to deploy GStreamer along your application. Thereare different mechanisms, which have been reviewed in Deploying your application. Fpso mac os. The details for someof the mechanisms are given here, and more options might be added tothis documentation in the future.
**FIXME: PackageMaker is dead we need a new solution **
This is the easiest way to deploy GStreamer, although most of the timeit installs unnecessary files which grow the size of the installer andthe target drive free space requirements. Since GStreamer might be sharedamong all applications that use it, though, the extra space requirementsare somewhat blurred.
With PackageMaker, simply add GStreamer **runtime ** disk image(the same one you used to install the runtime in your developmentmachine) inside your installerpackage and create a post-install script that mounts the disk image andinstalls GStreamer package. You can use the following example, where youshould replace $INSTALL_PATH
with the path where your installer copiedGStreamer's disk image files (the /tmp
directory is good place toinstall it as it will be removed at the end of the installation):
You can decide to distribute a private copy of GStreamer with yourapplication, although it's not the recommended method. In this case,simply copy the framework to the application's Frameworks folder asdefined in the bundle programmingguide:
Note that you can have several versions of GStreamer, and targetingdifferent architectures, installed in the system. Make sure you onlycopy the version you need and that you update accordingly the linkGStreamer.framework/Version/Current
:
Since GStreamer will be relocated, you will need to follow theinstructions on how to relocate GStreamer at the end of this page.
On the other side of the spectrum, if you want to reduce the spacerequirements (and installer size) to the maximum, you can manuallychoose which GStreamer libraries to deploy. Unfortunately, you are onyour own on this road, besides using the object file displaying tool:otool.Being a similar technique to deploying a private copy of GStreamer, keepin mind that you should relocate GStreamer too, as explained at the end ofthis page.
Bear also in mind that GStreamer is modular in nature. Plug-ins areloaded depending on the media that is being played, so, if you do notknow in advance what files you are going to play, you do not know whichplugins and shared libraries you need to deploy.
This will produce a smaller installer than deploying completeGStreamer, without the added burden of having to manually pick eachlibrary. You just need to know which packages your application requires.

In some situations we might need to relocate GStreamer, moving it to adifferent place in the file system, like for instance when we areshipping a private copy of GStreamer with our application.
On Darwin operating systems, the dynamic linker doesn't locate dependentdynamic libraries using their leaf name, but instead it uses full paths,which makes it harder to relocate them as explained in the DYNAMICLIBRARY LOADING section ofdyld'sman page:
Unlike many other operating systems, Darwin does not locate dependentdynamic libraries via their leaf file name. Instead the full path toeach dylib is used (e.g. /usr/lib/libSystem.B.dylib). But there aretimes when a full path is not appropriate; for instance, may want yourbinaries to be installable in anywhere on the disk.
We can get the list of paths used by an object file to locate itsdependent dynamic librariesusing otool:
As you might have already noticed, if we move GStreamer to a differentfolder, it will stop working because the runtime linker won't be able tofind gstreamer-1.0
in the previous location/Library/Frameworks/GStreamer.framework/Versions/0.10/x86/lib/libgstreamer-1.0.0.dylib
. Rock, paper, geometry! mac os.
This full path is extracted from the dynamic library install name, a path that is used by the linker to determine its location. Theinstall name of a library can be retrieved withotool too:
Any object file that links to the dynamic library gstreamer-1.0
willuse thepath /Library/Frameworks/GStreamer.framework/Versions/0.10/x86/lib/libgstreamer-1.0.0.dylib
tolocate it, as we saw previously with gst-launch-1.0
.
Since working exclusively with full paths wouldn't let us install ourbinaries anywhere in the path, the linker provides a mechanism of stringsubstitution, adding three variables that can be used as a path prefix.At runtime the linker will replace them with the generated path for theprefix. These variables are @executable_path
,@loader_path
and @rpath
, described in depth in the DYNAMIC LIBRARYLOADING sectionof dyld'sman page.
For our purpose we will use the @executable_path
variable, which isreplaced with a fixed path, the path to the directory containing themain executable: /Applications/MyApp.app/Contents/MacOS
.The @loader_path
variable can't be used in our scope, because it willbe replaced with the path to the directory containing the mach-o binarythat loaded the dynamic library, which can vary.
Therefore, in order to relocate GStreamer we will need to replace allpathscontaining /Library/Frameworks/GStreamer.framework/
with @executable_path/./Frameworks/GStreamer.framework/
, whichcan be done usingthe install_name_toolutility
As mentioned in the previous section, we can usethe install_name_tool
in combination with otool
to list all pathsfor dependant dynamic libraries and modify them to use the new location.However GStreamer has a huge list of binaries and doing it manually wouldbe a painful task. That's why a simple relocation script is providedwhich you can find in cerbero's repository(cerbero/tools/osxrelocator.py
). This scripts takes 3 parameters:
directory
: the directory to parse looking for binariesold_prefix
: the old prefix we want to change (eg:/Library/Frameworks/GStreamer.framework
)new_prefix
: the new prefix we want to use(eg: @executable_path/./Frameworks/GStreamer.framework/
)When looking for binaries to fix, we will run the script in thefollowingdirectories:
The application also needs to set the following environment variables tohelp other libraries finding resources in the newpath:
GST_PLUGIN_SYSTEM_PATH=/Applications/MyApp.app/Contents/Frameworks/GStreamer.framework/Versions/Current/lib/gstreamer-1.0
GST_PLUGIN_SCANNER=/Applications/MyApp.app/Contents/Frameworks/GStreamer.framework/Versions/Current/libexec/gstreamer-1.0/gst-plugin-scanner
GTK_PATH=/Applications/MyApp.app/Contents/Frameworks/GStreamer.framework/Versions/Current/
GIO_EXTRA_MODULES=/Applications/MyApp.app/Contents/Frameworks/GStreamer.framework/Versions/Current/lib/gio/modules
You can use the following functions:
C: putenv('VAR=/foo/bar')
Python: os.environ['VAR'] ='/foo/var'
Since the release of System 1 in January 1984, Apple has played an integral role in designing and implementing the graphical user interface (GUI) as we know it.
With the announcement of OS X Mountain Lion this week, Apple is continuing the process it started with Lion by streamlining the connection between the Mac and iOS.
We wanted to take a look at some of the biggest changes in the history of the Mac Operating System over the last 28 years. Looking back, I can't help but be struck by how many elements of the original Macintosh OS are still there more than 30 years after the project started taking shape.
It's a testament to the work of Bill Atkinson, Andy Hertzfeld, Bud Tribble and the other members of the original Macintosh team that so many aspects from System 1 have become integral to personal computing as we know it today.
There are a few phases in the evolution of the Mac OS that are of particular note. System 7 was the longest-running release for Apple (until OS X); it shipped with all Macintosh machines from 1991 to 1997. If you're in your mid-to-late 20s and used a Mac in elementary or middle school, chances are it was running some iteration of System 7.
One of the many challenges Apple faced in the 1990s was figuring out a new operating system strategy. As revolutionary as the original Mac OS work was, by 1994 it was starting to look stagnant and stale. This was especially true after the first release of Windows NT in 1993, which cemented Microsoft's place in the corporate and enterprise space.
After the Copland project was cancelled in 1996, Apple was left to search for an operating system it could acquire. That led to the purchase of NeXT and its NeXTSTEP operating system.
Split worlds mac os. Not only would NeXT technology serve as the foundation for the future of Apple as it is known today (OS X and iOS are direct descendants of NeXTSTEP), it was responsible for bringing Steve Jobs back to Apple.
It would end up taking ten years from the beginning of the search for a next-generation Mac OS. But the hunt finally reached its quarry with the release of Mac OS X in 2001. But it would take until Mac OS X 10.2 (Jaguar) before the system was really able to hold its own.
Over the last decade, OS X has evolved into a powerful desktop and server platform — while also serving as the core for iOS. With OS X Mountain Lion, Apple is bringing more of the elements and features of its mobile OS to the desktop.
