Methods

  • Attach the #GstControlBinding to the object. If there already was a #GstControlBinding for this property it will be replaced.

    The object's reference count will be incremented, and any floating reference will be removed (see gst_object_ref_sink())

    Parameters

    Returns boolean

  • 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

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: 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

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transformTo: TClosure<any, any>

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

    • transformFrom: TClosure<any, any>

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

  • emit(sigName: string, ...args: any[]): void
  • forceFloating(): 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

  • freezeNotify(): 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

  • getAudioVideoOffset(): number
  • Get a copy of the current configuration of the player. This configuration can either be modified and used for the gst_player_set_config() call or it must be freed after usage.

    Returns Gst.Structure

  • getControlRate(): number
  • 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() in between. The length of the processing segment should be up to control-rate nanoseconds.

    If the object is not under property control, this will return %GST_CLOCK_TIME_NONE. This allows the element to avoid the sub-dividing.

    The control-rate is not expected to change if the element is in %GST_STATE_PAUSED or %GST_STATE_PLAYING.

    Returns number

  • getCurrentVisualization(): string
  • getData(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

  • getDuration(): number
  • Retrieves the duration of the media stream that self represents.

    Returns number

  • getGValueArray(propertyName: string, timestamp?: number, interval?: number, values?: any[]): boolean
  • 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.

    This function is useful if one wants to e.g. draw a graph of the control curve or apply a control curve sample by sample.

    Parameters

    • propertyName: string

      the name of the property to get

    • Optional timestamp: number

      the time that should be processed

    • Optional interval: number

      the time spacing between subsequent values

    • Optional values: any[]

      array to put control-values in

    Returns boolean

  • getMute(): boolean
  • getName(): string
  • 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.

    Free-function: g_free

    Returns string

  • Returns the parent of object. This function increases the refcount of the parent object so you should gst_object_unref() it after usage.

    Returns Gst.Object

  • getPathString(): string
  • Generates a string describing the path of object in the object hierarchy. Only useful (or used) for debugging.

    Free-function: g_free

    Returns string

  • getPosition(): number
  • getProperty(propertyName?: 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 propertyName: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • getQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • getRate(): number
  • getSubtitleUri(): string
  • getSubtitleVideoOffset(): number
  • getUri(): string
  • getValue(propertyName: string, timestamp?: number): any
  • Gets the value for the given controlled property at the requested time.

    Parameters

    • propertyName: string

      the name of the property to get

    • Optional timestamp: number

      the time the control-change should be read from

    Returns any

  • Get a snapshot of the currently selected video stream, if any. The format can be selected with format and optional configuration is possible with config Currently supported settings are:

    • width, height of type G_TYPE_INT
    • pixel-aspect-ratio of type GST_TYPE_FRACTION Except for GST_PLAYER_THUMBNAIL_RAW_NATIVE format, if no config is set, pixel-aspect-ratio would be 1/1

    Parameters

    Returns Sample

  • getVolume(): number
  • Returns the current volume level, as a percentage between 0 and 1.

    Returns number

  • 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

  • hasActiveControlBindings(): boolean
  • Check if object has an ancestor ancestor somewhere up in the hierarchy. One can e.g. check if a #GstElement is inside a #GstPipeline.

    Parameters

    • ancestor: Gst.Object

      a #GstObject to check as ancestor

    Returns boolean

  • Check if object has an ancestor ancestor somewhere up in the hierarchy. One can e.g. check if a #GstElement is inside a #GstPipeline.

    Parameters

    • ancestor: Gst.Object

      a #GstObject to check as ancestor

    Returns boolean

  • Check if parent is the parent of object. E.g. a #GstElement can check if it owns a given #GstPad.

    Parameters

    • parent: Gst.Object

      a #GstObject to check as parent

    Returns boolean

  • hasColorBalance(): boolean
  • Checks whether the player has color balance support available.

    Returns boolean

  • isFloating(): boolean
  • notify(propertyName: 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

    • propertyName: 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.

  • pause(): void
  • play(): void
  • ref(...args: any[]): any
  • Increments the reference count on object. This function does not take the lock on object because it relies on atomic refcounting.

    This object returns the input parameter to ease writing constructs like : result = gst_object_ref (object->parent);

    Parameters

    • Rest ...args: any[]

    Returns any

  • 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

  • runDispose(): 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(position: number): void
  • Seeks the currently-playing stream to the absolute position time in nanoseconds.

    Parameters

    • position: number

      position to seek in nanoseconds

    Returns void

  • setAudioTrack(streamIndex: number): boolean
  • setAudioTrackEnabled(enabled: boolean): void
  • Enable or disable the current audio track.

    Parameters

    • enabled: boolean

      TRUE or FALSE

    Returns void

  • setAudioVideoOffset(offset: number): void
  • Sets audio-video-offset property by value of offset

    Parameters

    • offset: number

      #gint64 in nanoseconds

    Returns void

  • Sets the current value of the indicated channel type to the passed value.

    Parameters

    • type: PlayerColorBalanceType

      #GstPlayerColorBalanceType

    • value: number

      The new value for the type, ranged [0,1]

    Returns void

  • Set the configuration of the player. If the player is already configured, and the configuration haven't change, this function will return %TRUE. If the player is not in the GST_PLAYER_STATE_STOPPED, this method will return %FALSE and active configuration will remain.

    config is a #GstStructure that contains the configuration parameters for the player.

    This function takes ownership of config.

    Parameters

    Returns boolean

  • setControlBindingDisabled(propertyName: string, disabled: boolean): void
  • 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.

    Parameters

    • propertyName: string

      property to disable

    • disabled: boolean

      boolean that specifies whether to disable the controller or not.

    Returns void

  • setControlBindingsDisabled(disabled: boolean): void
  • This function is used to disable all controlled properties of the object for some time, i.e. gst_object_sync_values() will do nothing.

    Parameters

    • disabled: boolean

      boolean that specifies whether to disable the controller or not.

    Returns void

  • setControlRate(controlRate: number): void
  • 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() in between. The length of the processing segment should be up to control-rate nanoseconds.

    The control-rate should not change if the element is in %GST_STATE_PAUSED or %GST_STATE_PLAYING.

    Parameters

    • controlRate: number

      the new control-rate in nanoseconds.

    Returns void

  • setData(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

  • setMute(val: boolean): void
  • %TRUE if the currently-playing stream should be muted.

    Parameters

    • val: boolean

      Mute state the should be set

    Returns void

  • setName(name: string): boolean
  • 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.

    Parameters

    • name: string

      new name of object

    Returns boolean

  • 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()).

    Parameters

    Returns boolean

  • setProperty(propertyName: string, value?: any): void
  • Sets a property on an object.

    Parameters

    • propertyName: string

      the name of the property to set

    • Optional value: any

      the value

    Returns void

  • setRate(rate: number): void
  • Playback at specified rate

    Parameters

    • rate: number

      playback rate

    Returns void

  • setSubtitleTrack(streamIndex: number): boolean
  • setSubtitleTrackEnabled(enabled: boolean): void
  • Enable or disable the current subtitle track.

    Parameters

    • enabled: boolean

      TRUE or FALSE

    Returns void

  • setSubtitleUri(uri: string): void
  • Sets the external subtitle URI. This should be combined with a call to gst_player_set_subtitle_track_enabled(player, TRUE) so the subtitles are actually rendered.

    Parameters

    • uri: string

      subtitle URI

    Returns void

  • setSubtitleVideoOffset(offset: number): void
  • Sets subtitle-video-offset property by value of offset

    Parameters

    • offset: number

      #gint64 in nanoseconds

    Returns void

  • setUri(uri: string): void
  • Sets the next URI to play.

    Parameters

    • uri: string

      next URI to play.

    Returns void

  • setVideoTrack(streamIndex: number): boolean
  • setVideoTrackEnabled(enabled: boolean): void
  • Enable or disable the current video track.

    Parameters

    • enabled: boolean

      TRUE or FALSE

    Returns void

  • setVisualization(name: string): boolean
  • setVisualizationEnabled(enabled: boolean): void
  • Enable or disable the visualization.

    Parameters

    • enabled: boolean

      TRUE or FALSE

    Returns void

  • setVolume(val: number): void
  • Sets the volume level of the stream as a percentage between 0 and 1.

    This volume is a linear factor. For showing the volume in a GUI it might make sense to first convert from a different format. Volume sliders should usually use a cubic volume. See gst_stream_volume_convert_volume().

    Parameters

    • val: number

      the new volume level, as a percentage between 0 and 1

    Returns void

  • stealData(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

  • stealQdata(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

  • stop(): void
  • Stops playing the current stream and resets to the first position in the stream.

    Returns void

  • suggestNextSync(): number
  • syncValues(timestamp: number): boolean
  • Sets the properties of the object, according to the #GstControlSources that (maybe) handle them and for the given timestamp.

    If this function fails, it is most likely the application developers fault. Most probably the control sources are not setup correctly.

    Parameters

    • timestamp: number

      the time that should be processed

    Returns boolean

  • thawNotify(): 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

  • unparent(): void
  • Clear the parent of object, removing the associated reference. This function decreases the refcount of object.

    MT safe. Grabs and releases object's lock.

    Returns void

  • unref(): void
  • 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 unref method should never be called with the LOCK held since this might deadlock the dispose function.

    Returns void

  • watchClosure(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

  • checkUniqueness(list: Gst.Object[], name: string): boolean
  • 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.

    Parameters

    • list: Gst.Object[]

      a list of #GstObject to check through

    • name: string

      the name to search for

    Returns boolean

  • compatControl(what: number, data: object): number
  • configGetPositionUpdateInterval(config: Gst.Structure): number
  • Return the user agent which has been configured using gst_player_config_set_user_agent() if any.

    Parameters

    Returns string

  • configSetPositionUpdateInterval(config: Gst.Structure, interval: number): void
  • set interval in milliseconds between two position-updated signals. pass 0 to stop updating the position.

    Parameters

    • config: Gst.Structure

      a #GstPlayer configuration

    • interval: number

      interval in ms

    Returns void

  • configSetSeekAccurate(config: Gst.Structure, accurate: boolean): void
  • Enable or disable accurate seeking. When enabled, elements will try harder to seek as accurately as possible to the requested seek position. Generally it will be slower especially for formats that don't have any indexes or timestamp markers in the stream.

    If accurate seeking is disabled, elements will seek as close as the request position without slowing down seeking too much.

    Accurate seeking is disabled by default.

    Parameters

    • config: Gst.Structure

      a #GstPlayer configuration

    • accurate: boolean

      accurate seek or not

    Returns void

  • configSetUserAgent(config: Gst.Structure, agent: string): void
  • Set the user agent to pass to the server if player needs to connect to a server during playback. This is typically used when playing HTTP or RTSP streams.

    Parameters

    • config: Gst.Structure

      a #GstPlayer configuration

    • agent: string

      the string to use as user agent

    Returns void

  • 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.

    MT safe. This function grabs and releases object's LOCK for getting its path string.

    Parameters

    • object: GObject.Object

      the #GObject that signalled the notify.

    • orig: Gst.Object

      a #GstObject that initiated the notify.

    • pspec: ParamSpec

      a #GParamSpec of the property.

    • excludedProps: string[]

      a set of user-specified properties to exclude or %NULL to show all changes.

    Returns void

  • 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

    • gIface: TypeInterface

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

    • propertyName: 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

    • gIface: 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

    • gIface: TypeInterface

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

    Returns ParamSpec[]

  • Creates a new #GstPlayer instance that uses signal_dispatcher to dispatch signals to some event loop system, or emits signals directly if NULL is passed. See gst_player_g_main_context_signal_dispatcher_new().

    Video is going to be rendered by video_renderer, or if %NULL is provided no special video set up will be done and some default handling will be performed.

    Parameters

    Returns GstPlayer.Player

  • 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

    • objectType: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object

  • 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.

    Either newobj and the value pointed to by oldobj may be %NULL.

    Parameters

    • oldobj: Gst.Object

      pointer to a place of a #GstObject to replace

    • newobj: Gst.Object

      a new #GstObject

    Returns [boolean, Gst.Object]
