Prerequisites

To develop applications using the GStreamer SDK for OS X you will need OS X Snow Leopard (10.6) or later and XCode 3.2.6 or later.

The recommended system is Mac OS X Lion with XCode 4

Installing the SDK for 32-bits platforms requires approximately 145MB of free disk space for the runtime and 193MB for the development files.

Installing the SDK for 64-bits platforms requires approximately 152MB of free disk space for the runtime and 223MB for the development files.

Download and install the SDK

There are 3 sets of files in the SDK:

  • The runtime files are needed to run GStreamer applications. You probably want to distribute these files with your application (or the installer below).
  • The development files are additional files you need to create GStreamer applications.
  • Mac OS X packages that you can use with PackageMaker to deploy GStreamer with your application

Get both the runtime and the development installers from here:

On Mac OS X 10.6 (Snow Leopard) you have to install Python 2.7 manually. It is included in later versions of OS X already. You can get it from here.

Due to the size of these files, usage of a Download Manager is highly recommended. Take a look at this list if you do not have one installed. If, after downloading, the installer reports itself as corrupt, chances are that the connection ended before the file was complete. A Download Manager will typically re-start the process and fetch the missing parts.

The downloads are Apple Disk Images (.dmg) containing an Installer Package (.pkg). Double click in the installer to start the installation process.

These are some paths of the GStreamer framework that you might find useful:

  • /Library/Frameworks/GStreamer.framework/: Framework's root path 
  • /Library/Frameworks/GStreamer.framework/Versions: path with all the versions of the framework
  • /Library/Frameworks/GStreamer.framework/Versions/Current: link to the current version of the framework
  • /Library/Frameworks/GStreamer.framework/Headers: path with the development headers
  • /Library/Frameworks/GStreamer.framework/Commands: link to the commands provided by the framework, such as gst-inspect-0.10 or gst-launch-0.10

Configure your development environment

Building the tutorials

The tutorial's code, along with project files and a solution file for them all are included in the SDK. The source code and the XCode project files are located in /Library/Frameworks/GStreamer.framework/Current/share/gst-sdk/tutorials.

To start building the tutorials, create a new folder in your Documents directory and copy the folder /Library/Frameworks/GStreamer.framework/Current/share/gst-sdk/tutorials.

You can fire up XCode and load the project file.

Press the Run button to build and run the first tutorial. You can switch the tutorial to build selecting one of the available schemes. 

Creating new projects

The GStreamer SDK provides a framework that you can drag and drop to XCode to start using it, or using the linker option -framework GStreamer.

There is a small exception to the regular use of frameworks, and you will need to manually include the headers search path  /Library/Frameworks/GStreamer.framework/Headers

  • XCode: Add the headers path to Search Paths-> Header Search Paths
  • GCC: Using the compiler option -I/Library/Frameworks/GStreamer.framework/Headers
