/**

* 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>
|
|
* <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>
