Methods

  • Creates a binding between source_property on source and target_property on target.

    Whenever the source_property is changed the target_property is updated using the same value. For instance:

      g_object_bind_property (action, "active", widget, "sensitive", 0);
    

    Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.

    If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

    The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call g_object_unref() on the returned #GBinding instance.

    Removing the binding by calling g_object_unref() on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use g_binding_unbind() instead to be on the safe side.

    A #GObject can have multiple bindings.

    Parameters

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • target_property: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    Returns Binding

  • Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

    This function is the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

    Parameters

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • target_property: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transform_to: TClosure<any, any>

      a #GClosure wrapping the transformation function from the source to the target, or %NULL to use the default

    • transform_from: TClosure<any, any>

      a #GClosure wrapping the transformation function from the target to the source, or %NULL to use the default

    Returns Binding

  • collect_streams(): void
  • Find all payloader elements, they should be named pay%d in the element of media, and create #GstRTSPStreams for them.

    Collect all dynamic elements, named dynpay%d, and add them to the list of dynamic elements.

    Find all depayloader elements, they should be named depay%d in the element of media, and create #GstRTSPStreams for them.

    Returns void

  • disconnect(id: number): void
  • emit(sigName: "new-state", object: number, ...args: any[]): void
  • emit(sigName: "new-stream", object: RTSPStream, ...args: any[]): void
  • emit(sigName: "prepared", ...args: any[]): void
  • emit(sigName: "removed-stream", object: RTSPStream, ...args: any[]): void
  • emit(sigName: "target-state", object: number, ...args: any[]): void
  • emit(sigName: "unprepared", ...args: any[]): void
  • emit(sigName: "notify::bind-mcast-address", ...args: any[]): void

  • emit(sigName: "notify::transport-mode", ...args: any[]): void
  • emit(sigName: string, ...args: any[]): void
  • force_floating(): void
  • This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().

    Returns void

  • freeze_notify(): void
  • Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

    This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

    Returns void

  • get_base_time(): number
  • Get the base_time that is used by the pipeline in media.

    media must be prepared before this method returns a valid base_time.

    Returns number

  • get_buffer_size(): number
  • get_data(key?: string): object
  • Gets a named field from the objects table of associations (see g_object_set_data()).

    Parameters

    • Optional key: string

      name of the key for that association

    Returns object

  • get_do_retransmission(): boolean
  • get_dscp_qos(): number
  • get_latency(): number
  • get_max_mcast_ttl(): number
  • get_multicast_iface(): string
  • get_property(property_name?: string, value?: any): void
  • Gets a property of an object.

    The value can be:

    • an empty #GValue initialized by %G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a #GValue initialized with the expected type of the property
    • a #GValue initialized with a type to which the expected type of the property can be transformed

    In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().

    Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

    Parameters

    • Optional property_name: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • get_qdata(quark: number): object
  • get_rate_control(): boolean
  • get_rates(): [boolean, number, number]
  • get_retransmission_time(): number
  • Get the #GstNetTimeProvider for the clock used by media. The time provider will listen on address and port for client time requests.

    Parameters

    • address: string

      an address or %NULL

    • port: number

      a port or 0

    Returns NetTimeProvider

  • getv(names: string[], values: any[]): void
  • Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • has_completed_sender(): boolean
  • is_bind_mcast_address(): boolean
  • is_eos_shutdown(): boolean
  • is_floating(): boolean
  • is_receive_only(): boolean
  • is_reusable(): boolean
  • is_shared(): boolean
  • is_stop_on_disconnect(): boolean
  • is_time_provider(): boolean
  • Check if media can provide a #GstNetTimeProvider for its pipeline clock.

    Use gst_rtsp_media_get_time_provider() to get the network clock.

    Returns boolean

  • lock(): void
  • Lock the entire media. This is needed by callers such as rtsp_client to protect the media when it is shared by many clients. The lock prevents that concurrent clients alters the shared media, while one client already is working with it. Typically the lock is taken in external RTSP API calls that uses shared media such as DESCRIBE, SETUP, ANNOUNCE, TEARDOWN, PLAY, PAUSE.

    As best practice take the lock as soon as the function get hold of a shared media object. Release the lock right before the function returns.

    Returns void

  • n_streams(): number
  • notify(property_name: string): void
  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    • property_name: string

      the name of a property installed on the class of object.

    Returns void

  • Emits a "notify" signal for the property specified by pspec on object.

    This function omits the property name lookup, hence it is faster than g_object_notify().

    One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:

      enum
    {
    PROP_0,
    PROP_FOO,
    PROP_LAST
    };

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
    0, 100,
    50,
    G_PARAM_READWRITE);
    g_object_class_install_property (gobject_class,
    PROP_FOO,
    properties[PROP_FOO]);
    }

    and then notify a change on the "foo" property with:

      g_object_notify_by_pspec (self, properties[PROP_FOO]);
    

    Parameters

    • pspec: ParamSpec

      the #GParamSpec of a property installed on the class of object.

    Returns void

  • Prepare media for streaming. This function will create the objects to manage the streaming. A pipeline must have been set on media with gst_rtsp_media_take_pipeline().

    It will preroll the pipeline and collect vital information about the streams such as the duration.

    Parameters

    • thread: RTSPThread

      a #GstRTSPThread to run the bus handler or %NULL

    Returns boolean

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

  • Increase the reference count of object, and possibly remove the [floating][floating-ref] reference, if object has a floating reference.

    In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.

    Since GLib 2.56, the type of object will be propagated to the return type under the same conditions as for g_object_ref().

    Returns GObject.Object

  • run_dispose(): void
  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • Seek the pipeline of media to range with the given flags and rate, and trickmode_interval. media must be prepared with gst_rtsp_media_prepare(). In order to perform the seek operation, the pipeline must contain all needed transport parts (transport sinks).

    Parameters

    • range: RTSPTimeRange

      a #GstRTSPTimeRange

    • flags: Gst.SeekFlags

      The minimal set of #GstSeekFlags to use

    • rate: number

      the rate to use in the seek

    • trickmode_interval: number

      The trickmode interval to use for KEY_UNITS trick mode

    Returns boolean

  • seekable(): number
  • set_bind_mcast_address(bind_mcast_addr: boolean): void
  • Decide whether the multicast socket should be bound to a multicast address or INADDR_ANY.

    Parameters

    • bind_mcast_addr: boolean

      the new value

    Returns void

  • set_buffer_size(size: number): void
  • set_data(key: string, data?: object): void
  • Each object carries around a table of associations from strings to pointers. This function lets you set an association.

    If the object already had an association with that name, the old association will be destroyed.

    Internally, the key is converted to a #GQuark using g_quark_from_string(). This means a copy of key is kept permanently (even after object has been finalized) — so it is recommended to only use a small, bounded set of values for key in your program, to avoid the #GQuark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optional data: object

      data to associate with that key

    Returns void

  • set_do_retransmission(do_retransmission: boolean): void
  • set_dscp_qos(dscp_qos: number): void
  • Configure the dscp qos of attached streams to dscp_qos.

    Parameters

    • dscp_qos: number

      a new dscp qos value (0-63, or -1 to disable)

    Returns void

  • set_eos_shutdown(eos_shutdown: boolean): void
  • Set or unset if an EOS event will be sent to the pipeline for media before it is unprepared.

    Parameters

    • eos_shutdown: boolean

      the new value

    Returns void

  • set_latency(latency: number): void
  • set_max_mcast_ttl(ttl: number): boolean
  • set_multicast_iface(multicast_iface: string): void
  • set_pipeline_state(state: Gst.State): void
  • set_property(property_name: string, value?: any): void
  • set_rate_control(enabled: boolean): void
  • Define whether media will follow the Rate-Control=no behaviour as specified in the ONVIF replay spec.

    Parameters

    • enabled: boolean

    Returns void

  • set_retransmission_time(time: number): void
  • set_reusable(reusable: boolean): void
  • Set or unset if the pipeline for media can be reused after the pipeline has been unprepared.

    Parameters

    • reusable: boolean

      the new value

    Returns void

  • set_shared(shared: boolean): void
  • Set or unset if the pipeline for media can be shared will multiple clients. When shared is %TRUE, client requests for this media will share the media pipeline.

    Parameters

    • shared: boolean

      the new value

    Returns void

  • Set the state of media to state and for the transports in transports.

    media must be prepared with gst_rtsp_media_prepare();

    Parameters

    Returns boolean

  • set_stop_on_disconnect(stop_on_disconnect: boolean): void
  • Set or unset if the pipeline for media should be stopped when a client disconnects without sending TEARDOWN.

    Parameters

    • stop_on_disconnect: boolean

      the new value

    Returns void

  • Control how @ media will be suspended after the SDP has been generated and after a PAUSE request has been performed.

    Media must be unprepared when setting the suspend mode.

    Parameters

    Returns void

  • steal_data(key?: string): object
  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • Optional key: string

      name of the key

    Returns object

  • steal_qdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

    void
    object_add_to_user_list (GObject *object,
    const gchar *new_string)
    {
    // the quark, naming the object data
    GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
    // retrieve the old string list
    GList *list = g_object_steal_qdata (object, quark_string_list);

    // prepend new string
    list = g_list_prepend (list, g_strdup (new_string));
    // this changed 'list', so we need to set it again
    g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
    }
    static void
    free_string_list (gpointer data)
    {
    GList *node, *list = data;

    for (node = list; node; node = node->next)
    g_free (node->data);
    g_list_free (list);
    }

    Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • suspend(): boolean
  • Suspend media. The state of the pipeline managed by media is set to GST_STATE_NULL but all streams are kept. media can be prepared again with gst_rtsp_media_unsuspend()

    media must be prepared with gst_rtsp_media_prepare();

    Returns boolean

  • thaw_notify(): void
  • Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

    Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.

    It is an error to call this function when the freeze count is zero.

    Returns void

  • unlock(): void
  • unprepare(): boolean
  • Unprepare media. After this call, the media should be prepared again before it can be used again. If the media is set to be non-reusable, a new instance must be created.

    Returns boolean

  • unref(): void
  • Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

    If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.

    Returns void

  • unsuspend(): boolean
  • use_time_provider(time_provider: boolean): void
  • vfunc_constructed(): void
  • vfunc_dispatch_properties_changed(n_pspecs: number, pspecs: ParamSpec): void
  • vfunc_dispose(): void
  • vfunc_finalize(): void
  • vfunc_get_property(property_id: number, value?: any, pspec?: ParamSpec): void
  • vfunc_handle_message(message: Gst.Message): boolean
  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    virtual

    Parameters

    Returns void

  • Prepare media for streaming. This function will create the objects to manage the streaming. A pipeline must have been set on media with gst_rtsp_media_take_pipeline().

    It will preroll the pipeline and collect vital information about the streams such as the duration.

    virtual

    Parameters

    • thread: RTSPThread

      a #GstRTSPThread to run the bus handler or %NULL

    Returns boolean

  • vfunc_prepared(): void
  • vfunc_query_position(position: number): boolean
  • vfunc_query_stop(stop: number): boolean
  • vfunc_set_property(property_id: number, value?: any, pspec?: ParamSpec): void
  • vfunc_suspend(): boolean
  • Suspend media. The state of the pipeline managed by media is set to GST_STATE_NULL but all streams are kept. media can be prepared again with gst_rtsp_media_unsuspend()

    media must be prepared with gst_rtsp_media_prepare();

    virtual

    Returns boolean

  • vfunc_target_state(state: Gst.State): void
  • vfunc_unprepare(): boolean
  • Unprepare media. After this call, the media should be prepared again before it can be used again. If the media is set to be non-reusable, a new instance must be created.

    virtual

    Returns boolean

  • vfunc_unprepared(): void
  • vfunc_unsuspend(): boolean
  • Unsuspend media if it was in a suspended state. This method does nothing when the media was not in the suspended state.

    virtual

    Returns boolean

  • watch_closure(closure: TClosure<any, any>): void
  • This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

    Parameters

    • closure: TClosure<any, any>

      #GClosure to watch

    Returns void

  • compat_control(what: number, data: object): number
  • Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • g_iface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    • property_name: string

      name of a property to look up.

    Returns ParamSpec

  • Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

    This function is meant to be called from the interface's default vtable initialization function (the class_init member of #GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface.

    If pspec is a floating reference, it will be consumed.

    Parameters

    • g_iface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface.

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • g_iface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    Returns ParamSpec[]

  • Create a new #GstRTSPMedia instance. element is the bin element that provides the different streams. The #GstRTSPMedia object contains the element to produce RTP data for one or more related (audio/video/..) streams.

    Ownership is taken of element.

    Parameters

    Returns RTSPMedia

  • Creates a new instance of a #GObject subtype and sets its properties.

    Construction parameters (see %G_PARAM_CONSTRUCT, %G_PARAM_CONSTRUCT_ONLY) which are not explicitly specified are set to their default values.

    Parameters

    • object_type: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
