| * SECTION:gstconfig |
| * @short_description: Build configuration options |
| * |
| * This describes the configuration options for GStreamer. When building |
| * GStreamer there are a lot of parts (known internally as "subsystems" ) that |
| * can be disabled for various reasons. The most common reasons are speed and |
| * size, which is important because GStreamer is designed to run on embedded |
| * systems. |
| * |
| * If a subsystem is disabled, most of this changes are done in an API |
| * compatible way, so you don't need to adapt your code in most cases. It is |
| * never done in an ABI compatible way though. So if you want to disable a |
| * suybsystem, you have to rebuild all programs depending on GStreamer, too. |
| * |
| * If a subsystem is disabled in GStreamer, a value is defined in |
| * <gst/gst.h>. You can check this if you do subsystem-specific stuff. |
| * <example id="example-gstconfig"> |
| * <title>Doing subsystem specific things</title> |
| * <programlisting> |
| * &hash;ifndef GST_DISABLE_GST_DEBUG |
| * // do stuff specific to the debugging subsystem |
| * &hash;endif // GST_DISABLE_GST_DEBUG |
| * </programlisting> |
| * </example> |
