GstElementFactory
Create GstElements from a factory
GstElementFactory is used to create instances of elements. A GstElementfactory
can be added to a #GstPlugin as it is also a #GstPluginFeature.
Use gst_element_factory_new() to create a new factory which can be added to a plugin
with gst_plugin_add_feature().
gst_element_factory_add_pad_template() is used to add a padtemplate to the factory.
This function will enable the application to query for elementfactories that handle
a specific media type.
Use the gst_element_factory_find() and gst_element_factory_create() functions
to create element instances or use gst_element_factory_make() as a convenient
shortcut.
The following code example shows you how to create a GstFileSrc element.
#include <gst/gst.h>
GstElement *src;
GstElementFactory *srcfactory;
gst_init(&argc,&argv);
srcfactory = gst_element_factory_find("filesrc");
g_return_if_fail(srcfactory != NULL);
src = gst_element_factory_create(srcfactory,"src");
g_return_if_fail(src != NULL);
...
An elementfactory can be assigned a rank with gst_element_factory_set_rank()
so that the autopluggers can select a plugin more appropriatly
#GstElement, #GstPlugin, #GstPluginFeature, #GstPadTemplate.
