# Compiling
|
|
|
|
This section talks about the different things you can do when building
|
|
and shipping your applications and plugins.
|
|
|
|
## Embedding static elements in your application
|
|
|
|
The [Plugin Writer's Guide](plugin-development/index.md)
|
|
describes in great detail how to write elements for the GStreamer
|
|
framework. In this section, we will solely discuss how to embed such
|
|
elements statically in your application. This can be useful for
|
|
application-specific elements that have no use elsewhere in GStreamer.
|
|
|
|
Dynamically loaded plugins contain a structure that's defined using
|
|
`GST_PLUGIN_DEFINE ()`. This structure is loaded when the plugin is
|
|
loaded by the GStreamer core. The structure contains an initialization
|
|
function (usually called `plugin_init`) that will be called right after
|
|
that. It's purpose is to register the elements provided by the plugin
|
|
with the GStreamer framework. If you want to embed elements directly in
|
|
your application, the only thing you need to do is to replace
|
|
`GST_PLUGIN_DEFINE ()` with a call to `gst_plugin_register_static ()`.
|
|
As soon as you call `gst_plugin_register_static ()`, the elements will
|
|
from then on be available like any other element, without them having to
|
|
be dynamically loadable libraries. In the example below, you would be
|
|
able to call `gst_element_factory_make
|
|
("my-element-name", "some-name")` to create an instance of the element.
|
|
|
|
``` c
|
|
|
|
/*
|
|
* Here, you would write the actual plugin code.
|
|
*/
|
|
|
|
[..]
|

|
|
register_elements (GstPlugin *plugin)
|
|
{
|
|
return gst_element_register (plugin, "my-element-name",
|
|
GST_RANK_NONE, MY_PLUGIN_TYPE);
|
|
}
|
