Element metadata

The Element metadata provides extra element information. It is configured with gst_element_class_set_metadata or gst_element_class_set_static_metadata which takes the following parameters:

• A long, English, name for the element.

• The type of the element, see the docs/design/draft-klass.txt document in the GStreamer core source tree for details and examples.

• A brief description of the purpose of the element.

• The name of the author of the element, optionally followed by a contact email address in angle brackets.

For example:

gst_element_class_set_static_metadata (klass,
  "An example plugin",
  "Example/FirstExample",
  "Shows the basic structure of a plugin",
  "your name <your.name@your.isp>");
    

The element details are registered with the plugin during the _class_init () function, which is part of the GObject system. The _class_init () function should be set for this GObject in the function where you register the type with GLib.

static void
gst_my_filter_class_init (GstMyFilterClass * klass)
{
  GstElementClass *element_class = GST_ELEMENT_CLASS (klass);

[..]
  gst_element_class_set_static_metadata (element_klass,
    "An example plugin",
    "Example/FirstExample",
    "Shows the basic structure of a plugin",
    "your name <your.name@your.isp>");

}
