Disabling the indexers and URI handler code will only reduce the required amount of memory by a very small amount but on the other hand requires much more maintaince work. Apart from that many places of code are broken when disabling them. Disabling the enum types doesn't reduce the required amount of memory by more than a few bytes and makes it hard to fix bugs like #539772, i.e. use the enums as GObject properties.

/**

|
* 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>
