* #GstObject provides a root for the object hierarchy tree filed in by the
|
||||
* GStreamer library. It is currently a thin wrapper on top of
|
||||
* #GObject. It is an abstract class that is not very usable on its own.
|
||||
* #GInitiallyUnowned. It is an abstract class that is not very usable on its own.
|
||||
*
|
||||
* #GstObject gives us basic refcounting, parenting functionality and locking.
|
||||
* Most of the function are just extended for special GStreamer needs and can be
|
||||
* found under the same name in the base class of #GstObject which is #GObject
|
||||
* (e.g. g_object_ref() becomes gst_object_ref()).
|
||||
*
|
||||
* The most interesting difference between #GstObject and #GObject is the
|
||||
* "floating" reference count. A #GObject is created with a reference count of
|
||||
* 1, owned by the creator of the #GObject. (The owner of a reference is the
|
||||
* code section that has the right to call gst_object_unref() in order to
|
||||
* remove that reference.) A #GstObject is created with a reference count of 1
|
||||
* also, but it isn't owned by anyone; Instead, the initial reference count
|
||||
* of a #GstObject is "floating". The floating reference can be removed by
|
||||
* anyone at any time, by calling gst_object_sink(). gst_object_sink() does
|
||||
* nothing if an object is already sunk (has no floating reference).
|
||||
*
|
||||
* When you add a #GstElement to its parent container, the parent container will
|
||||
* do this:
|
||||
* <informalexample>
|
||||
* <programlisting>
|
||||
* gst_object_ref (GST_OBJECT (child_element));
|
||||
* gst_object_sink (GST_OBJECT (child_element));
|
||||
* </programlisting>
|
||||
* </informalexample>
|
||||
* This means that the container now owns a reference to the child element
|
||||
* (since it called gst_object_ref()), and the child element has no floating
|
||||
* reference.
|
||||
*
|
||||
* The purpose of the floating reference is to keep the child element alive
|
||||
* until you add it to a parent container, which then manages the lifetime of
|
||||
* the object itself:
|
||||
* <informalexample>
|
||||
* <programlisting>
|
||||
* element = gst_element_factory_make (factoryname, name);
|
||||
* // element has one floating reference to keep it alive
|
||||
* gst_bin_add (GST_BIN (bin), element);
|
||||
* // element has one non-floating reference owned by the container
|
||||
* </programlisting>
|
||||
* </informalexample>
|
||||
*
|
||||
* Another effect of this is, that calling gst_object_unref() on a bin object,
|
||||
* will also destoy all the #GstElement objects in it. The same is true for
|
||||
* calling gst_bin_remove().
|
||||
*
|
||||
* Special care has to be taken for all methods that gst_object_sink() an object
|
||||
* since if the caller of those functions had a floating reference to the object,
|
||||
* the object reference is now invalid.
|
||||
* Since #GstObject dereives from #GInitiallyUnowned, it also inherits the
|
||||
* floating reference. Be aware that functions such as gst_bin_add() and
|
||||
* gst_element_add_pad() take ownership of the floating reference.
|
||||
*
|
||||
* In contrast to #GObject instances, #GstObject adds a name property. The functions
|
||||
* gst_object_set_name() and gst_object_get_name() are used to set/get the name

|

* Pads have a #GstPadDirection, source pads produce data, sink pads consume
|

* data.
|
||||
*
|
||||
* Pads are typically created from a #GstPadTemplate with
|

* gst_pad_new_from_template().
|
||||
*
|
||||
* Pads have #GstCaps attached to it to describe the media type they are

* capable of dealing with. gst_pad_query_caps() and gst_pad_set_caps() are

* gst_pad_new_from_template() and are then added to a #GstElement. This usually

||||
* happens when the element is created but it can also happen dynamically based
|
||||
* on the data that the element is processing or based on the pads that the
|
||||
* application requests.
|
||||
*
|
||||
* Pads without pad templates can be created with gst_pad_new(),
|
||||
* which takes a direction and a name as an argument. If the name is NULL,
|
||||
* then a guaranteed unique name will be assigned to it.
|
||||
*
|
||||
* A #GstElement creating a pad will typically use the various

|

* linked to.
|

*
|

* Before dataflow is possible on the pads, they need to be activated with
|

* gst_pad_set_active().
|

*
|

* gst_pad_query() and gst_pad_peer_query() can be used to query various

|

* To send a #GstEvent on a pad, use gst_pad_send_event() and

* gst_pad_push_event(). Some events will be sticky on the pad, meaning that
|
||||
* after they pass on the pad they can be queried later with
|
||||
* gst_pad_get_sticky_event() and gst_pad_sticky_events_foreach().
|
||||
* gst_pad_get_current_caps() and gst_pad_has_current_caps() are convenience
|
