Sets our main struct and passes it to the parent class.
Checks whether the given plugin feature is at least the required version
Get the plugin that provides this feature.
Get the main Gtk struct
Get the name of the plugin that provides this feature.
Gets the rank of a plugin feature.
the main Gtk struct as a void*
Loads the plugin containing @feature if it's not already loaded. @feature is unaffected; use the return value instead.
Specifies a rank for a plugin feature, so that autoplugging uses the most appropriate feature.
Copies the list of features. Caller should call @gst_plugin_feature_list_free when done with the list.
Debug the plugin feature names in @list.
Unrefs each member of @list, then frees the list.
Compares the two given #GstPluginFeature instances. This function can be used as a #GCompareFunc when sorting by rank and then by name.

Checks to see if there is any object named @name in @list. This function does not do any locking of any kind. You might want to protect the provided list with the lock of the owner of the list. This function will lock each #GstObject in the list to compare the name, so be careful when passing a list with a locked object.
A default deep_notify signal callback for an object. The user data should contain a pointer to an array of strings that should be excluded from the notify. The default handler will print the new value of the property using g_print.
Increase the reference count of @object, and possibly remove the floating reference, if @object has a floating reference.
Atomically modifies a pointer to point to a new object. The reference count of @oldobj is decreased and the reference count of @newobj is increased.
Attach the #GstControlBinding to the object. If there already was a #GstControlBinding for this property it will be replaced.
A default error function that uses g_printerr() to display the error message and the optional debug sting..
Gets the corresponding #GstControlBinding for the property. This should be unreferenced again after use.
Obtain the control-rate for this @object. Audio processing #GstElement objects will use this rate to sub-divide their processing loop and call gst_object_sync_values() inbetween. The length of the processing segment should be up to @control-rate nanoseconds.
Gets a number of #GValues for the given controlled property starting at the requested time. The array @values need to hold enough space for @n_values of #GValue.
Returns a copy of the name of @object. Caller should g_free() the return value after usage. For a nameless object, this returns %NULL, which you can safely g_free() as well.
Returns the parent of @object. This function increases the refcount of the parent object so you should gst_object_unref() it after usage.
Generates a string describing the path of @object in the object hierarchy. Only useful (or used) for debugging.
Gets the value for the given controlled property at the requested time.
Gets a number of values for the given controlled property starting at the requested time. The array @values need to hold enough space for @n_values of the same type as the objects property's type.
Check if the @object has an active controlled properties.
Check if @object has an ancestor @ancestor somewhere up in the hierarchy. One can e.g. check if a #GstElement is inside a #GstPipeline.
Check if @object has an ancestor @ancestor somewhere up in the hierarchy. One can e.g. check if a #GstElement is inside a #GstPipeline.
Check if @parent is the parent of @object. E.g. a #GstElement can check if it owns a given #GstPad.
Increments the reference count on @object. This function does not take the lock on @object because it relies on atomic refcounting.
Removes the corresponding #GstControlBinding. If it was the last ref of the binding, it will be disposed.
This function is used to disable the control bindings on a property for some time, i.e. gst_object_sync_values() will do nothing for the property.
This function is used to disable all controlled properties of the @object for some time, i.e. gst_object_sync_values() will do nothing.
Change the control-rate for this @object. Audio processing #GstElement objects will use this rate to sub-divide their processing loop and call gst_object_sync_values() inbetween. The length of the processing segment should be up to @control-rate nanoseconds.
Sets the name of @object, or gives @object a guaranteed unique name (if @name is %NULL). This function makes a copy of the provided name, so the caller retains ownership of the name it sent.
Sets the parent of @object to @parent. The object's reference count will be incremented, and any floating reference will be removed (see gst_object_ref_sink()).
Returns a suggestion for timestamps where buffers should be split to get best controller results.
Sets the properties of the object, according to the #GstControlSources that (maybe) handle them and for the given timestamp.
Clear the parent of @object, removing the associated reference. This function decreases the refcount of @object.
Decrements the reference count on @object. If reference count hits zero, destroy @object. This function does not take the lock on @object as it relies on atomic refcounting.
The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.
This is a base class for anything that can be added to a #GstPlugin.
