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>"); } |
