    /// ## Properties
    ///
    ///
    /// #### `uri`
    ///  The uri of the file/resource to use. You can set a start index,
    /// a stop index and a sequence pattern.
    /// The format is <multifile://start:stop\`location`-pattern>.
    /// The pattern uses printf string formating.
    ///
    /// Example uris:
    ///
    /// multifile:///home/you/image\`03d`
    ///
    /// multifile://20:50@/home/you/sequence/\`04d`
    ///
    /// Readable | Writeable | Construct Only
    /// <details><summary><h4>TrackElement</h4></summary>
    ///
    ///
    /// #### `active`
    ///  Whether the effect of the element should be applied in its
    /// [`track`][struct@crate::TrackElement#track]. If set to [`false`], it will not be used in
    /// the output of the track.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `auto-clamp-control-sources`
    ///  Whether the control sources on the element (see
    /// [`TrackElementExt::set_control_source()`][crate::prelude::TrackElementExt::set_control_source()]) will be automatically
    /// updated whenever the [`in-point`][struct@crate::TimelineElement#in-point] or out-point of the
    /// element change in value.
    ///
    /// See [`TrackElementExt::clamp_control_source()`][crate::prelude::TrackElementExt::clamp_control_source()] for how this is done
    /// per control source.
    ///
    /// Default value: [`true`]
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `has-internal-source`
    ///  This property is used to determine whether the 'internal time'
    /// properties of the element have any meaning. In particular, unless
    /// this is set to [`true`], the [`in-point`][struct@crate::TimelineElement#in-point] and
    /// [`max-duration`][struct@crate::TimelineElement#max-duration] can not be set to any value other
    /// than the default 0 and `GST_CLOCK_TIME_NONE`, respectively.
    ///
    /// If an element has some *internal* *timed* source [`gst::Element`][crate::gst::Element] that it
    /// reads stream data from as part of its function in a [`Track`][crate::Track], then
    /// you'll likely want to set this to [`true`] to allow the
    /// [`in-point`][struct@crate::TimelineElement#in-point] and [`max-duration`][struct@crate::TimelineElement#max-duration] to
    /// be set.
    ///
    /// The default value is determined by the `GESTrackElementClass`
    /// `default_has_internal_source` class property. For most
    /// `GESSourceClass`-es, this will be [`true`], with the exception of those
    /// that have a potentially *static* source, such as `GESImageSourceClass`
    /// and `GESTitleSourceClass`. Otherwise, this will usually be [`false`].
    ///
    /// For most [`Operation`][crate::Operation]-s you will likely want to leave this set to
    /// [`false`]. The exception may be for an operation that reads some stream
    /// data from some private internal source as part of manipulating the
    /// input data from the usual linked upstream [`TrackElement`][crate::TrackElement].
    ///
    /// For example, you may want to set this to [`true`] for a
    /// [`TrackType::VIDEO`][crate::TrackType::VIDEO] operation that wraps a `textoverlay` that reads
    /// from a subtitle file and places its text on top of the received video
    /// data. The [`in-point`][struct@crate::TimelineElement#in-point] of the element would be used
    /// to shift the initial seek time on the `textoverlay` away from 0, and
    /// the [`max-duration`][struct@crate::TimelineElement#max-duration] could be set to reflect the
    /// time at which the subtitle file runs out of data.
    ///
    /// Note that GES can not support track elements that have both internal
    /// content and manipulate the timing of their data streams (time
    /// effects).
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `track`
    ///  The track that this element belongs to, or [`None`] if it does not
    /// belong to a track.
    ///
    /// Readable
    ///
    ///
    /// #### `track-type`
    ///  The track type of the element, which determines the type of track the
    /// element can be added to (see [`track-type`][struct@crate::Track#track-type]). This should
    /// correspond to the type of data that the element can produce or
    /// process.
    ///
    /// Readable | Writeable | Construct
    /// </details>
    /// <details><summary><h4>TimelineElement</h4></summary>
    ///
    ///
    /// #### `duration`
    ///  The duration that the element is in effect for in the timeline (a
    /// time difference in nanoseconds using the time coordinates of the
    /// timeline). For example, for a source element, this would determine
    /// for how long it should output its internal content for. For an
    /// operation element, this would determine for how long its effect
    /// should be applied to any source content.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `in-point`
    ///  The initial offset to use internally when outputting content (in
    /// nanoseconds, but in the time coordinates of the internal content).
    ///
    /// For example, for a [`VideoUriSource`][crate::VideoUriSource] that references some media
    /// file, the "internal content" is the media file data, and the
    /// in-point would correspond to some timestamp in the media file.
    /// When playing the timeline, and when the element is first reached at
    /// timeline-time [`start`][struct@crate::TimelineElement#start], it will begin outputting the
    /// data from the timestamp in-point **onwards**, until it reaches the
    /// end of its [`duration`][struct@crate::TimelineElement#duration] in the timeline.
    ///
    /// For elements that have no internal content, this should be kept
    /// as 0.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `max-duration`
    ///  The full duration of internal content that is available (a time
    /// difference in nanoseconds using the time coordinates of the internal
    /// content).
    ///
    /// This will act as a cap on the [`in-point`][struct@crate::TimelineElement#in-point] of the
    /// element (which is in the same time coordinates), and will sometimes
    /// be used to limit the [`duration`][struct@crate::TimelineElement#duration] of the element in
    /// the timeline.
    ///
    /// For example, for a [`VideoUriSource`][crate::VideoUriSource] that references some media
    /// file, this would be the length of the media file.
    ///
    /// For elements that have no internal content, or whose content is
    /// indefinite, this should be kept as `GST_CLOCK_TIME_NONE`.
    ///
    /// Readable | Writeable | Construct
    ///
    ///
    /// #### `name`
    ///  The name of the element. This should be unique within its timeline.
    ///
    /// Readable | Writeable | Construct
    ///
    ///
    /// #### `parent`
    ///  The parent container of the element.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `priority`
    ///  The priority of the element.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `serialize`
    ///  Whether the element should be serialized.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `start`
    ///  The starting position of the element in the timeline (in nanoseconds
    /// and in the time coordinates of the timeline). For example, for a
    /// source element, this would determine the time at which it should
    /// start outputting its internal content. For an operation element, this
    /// would determine the time at which it should start applying its effect
    /// to any source content.
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `timeline`
    ///  The timeline that the element lies within.
