25 * @short_description: Build configuration options
27 * This describes the configuration options for GStreamer. When building
28 * GStreamer there are a lot of parts (known internally as "subsystems" ) that
29 * can be disabled for various reasons. The most common reasons are speed and
30 * size, which is important because GStreamer is designed to run on embedded
33 * If a subsystem is disabled, most of this changes are done in an API
34 * compatible way, so you don't need to adapt your code in most cases. It is
35 * never done in an ABI compatible way though. So if you want to disable a
36 * suybsystem, you have to rebuild all programs depending on GStreamer, too.
38 * If a subsystem is disabled in GStreamer, a value is defined in
39 * <gst/gst.h>. You can check this if you do subsystem-specific stuff.
