Static methods:

• public static Quark error_quark ()
  Get the error quark.
• public static Plugin? load_by_name (string name)
  Load the named plugin. Refs the plugin.
• public static Plugin? load_file (string filename) throws Error
  Loads the given plugin and refs it. Caller needs to unref after use. reference to the newly-loaded GstPlugin, or NULL if an error occurred.
• public static bool register_static (int major_version, int minor_version, string name, string description, PluginInitFunc init_func, string version, string license, string source, string package, string origin)
  Registers a static plugin, ie. a plugin which is private to an application or library and contained within the application or library (as opposed to being shipped as a separate module file). You must make sure that GStreamer has been initialised (with init or via init_get_option_group) before calling this function.
• public static bool register_static_full (int major_version, int minor_version, string name, string description, PluginInitFullFunc init_full_func, string version, string license, string source, string package, string origin)
  Registers a static plugin, ie. a plugin which is private to an application or library and contained within the application or library (as opposed to being shipped as a separate module file) with a PluginInitFullFunc which allows user data to be passed to the callback function (useful for bindings). You must make sure that GStreamer has been initialised (with init or via init_get_option_group) before calling this function.

Creation methods:

• protected Plugin ()

Methods:

• public void add_dependency (string?[] env_vars, string?[] paths, string?[] names, PluginDependencyFlags flags)
  Make GStreamer aware of external dependencies which affect the feature set of this plugin (ie. the elements or typefinders associated with it). GStreamer will re-inspect plugins with external dependencies whenever any of the external dependencies change. This is useful for plugins which wrap other plugin systems, e.g. a plugin which wraps a plugin-based visualisation library and makes visualisations available as GStreamer elements, or a codec loader which exposes elements and/or caps dependent on what external codec libraries are currently installed.
• public void add_dependency_simple (string? env_vars, string? paths, string? names, PluginDependencyFlags flags)
  Make GStreamer aware of external dependencies which affect the feature set of this plugin (ie. the elements or typefinders associated with it). GStreamer will re-inspect plugins with external dependencies whenever any of the external dependencies change. This is useful for plugins which wrap other plugin systems, e.g. a plugin which wraps a plugin-based visualisation library and makes visualisations available as GStreamer elements, or a codec loader which exposes elements and/or caps dependent on what external codec libraries are currently installed. Convenience wrapper function for add_dependency which takes simple strings as arguments instead of string arrays, with multiple arguments separated by predefined delimiters (see above).
• public unowned Structure get_cache_data ()
  Gets the plugin specific data cache. If it is null there is no cached data stored. This is the case when the registry is getting rebuilt.
• public unowned string get_description ()
  Get the long descriptive name of the plugin
• public unowned string get_filename ()
  get the filename of the plugin
• public unowned string get_license ()
  get the license of the plugin
• public unowned Module get_module ()
  Gets the Module of the plugin. If the plugin isn't loaded yet, NULL is returned. plugin isn't loaded yet.
• public unowned string get_name ()
  Get the short name of the plugin
• public unowned string get_origin ()
  get the URL where the plugin comes from
• public unowned string get_package ()
  get the package the plugin belongs to.
• public unowned string get_source ()
  get the source module the plugin belongs to.
• public unowned string get_version ()
  get the version of the plugin
• public bool is_loaded ()
  queries if the plugin is loaded into memory
• public Plugin? load ()
  Loads plugin. Note that the *return value* is the loaded plugin; plugin is untouched. The normal use pattern of this function goes like this:
• public bool name_filter (Plugin plugin, string name)
  A standard filter that returns TRUE when the plugin is of the given name.
• public void set_cache_data (owned Structure cache_data)
  Adds plugin specific data to cache. Passes the ownership of the structure to the plugin. The cache is flushed every time the registry is rebuilt.
