This describes the configureation 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.
|
|

<para>
|
|
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>
