    ///
    /// The default asset ID is GESTestClip, but the framerate and video

    /// ```text
    /// framerate=60/1, width=1920, height=1080, max-duration=5.0

    ///
    /// ## Properties
    ///
    ///
    /// #### `freq`
    ///  The frequency to generate for audio track elements.
    ///
    /// Readable | Writeable | Construct
    ///
    ///
    /// #### `mute`
    ///  Whether the sound will be played or not.
    ///
    /// Readable | Writeable | Construct
    ///
    ///
    /// #### `volume`
    ///  The volume for the audio track elements.
    ///
    /// Readable | Writeable | Construct
    ///
    ///
    /// #### `vpattern`
    ///  Video pattern to display in video track elements.
    ///
    /// Readable | Writeable | Construct
    /// <details><summary><h4>Clip</h4></summary>
    ///
    ///
    /// #### `duration-limit`
    ///  The maximum [`duration`][struct@crate::TimelineElement#duration] that can be *currently* set
    /// for the clip, taking into account the [`in-point`][struct@crate::TimelineElement#in-point],
    /// [`max-duration`][struct@crate::TimelineElement#max-duration], [`active`][struct@crate::TrackElement#active], and
    /// [`track`][struct@crate::TrackElement#track] properties of its children, as well as any
    /// time effects. If there is no limit, this will be set to
    /// `GST_CLOCK_TIME_NONE`.
    ///
    /// Note that whilst a clip has no children in any tracks, the limit will
    /// be unknown, and similarly set to `GST_CLOCK_TIME_NONE`.
    ///
    /// If the duration-limit would ever go below the current
    /// [`duration`][struct@crate::TimelineElement#duration] of the clip due to a change in the above
    /// variables, its [`duration`][struct@crate::TimelineElement#duration] will be set to the new
    /// limit.
    ///
    /// Readable
    ///
    ///
    /// #### `layer`
    ///  The layer this clip lies in.
    ///
    /// If you want to connect to this property's [`notify`][struct@crate::glib::Object#notify] signal,
    /// you should connect to it with `g_signal_connect_after()` since the
    /// signal emission may be stopped internally.
    ///
    /// Readable
    ///
    ///
    /// #### `supported-formats`
    ///  The [`TrackType`][crate::TrackType]-s that the clip supports, which it can create
    /// [`TrackElement`][crate::TrackElement]-s for. Note that this can be a combination of
    /// [`TrackType`][crate::TrackType] flags to indicate support for several
    /// [`track-type`][struct@crate::TrackElement#track-type] elements.
    ///
    /// Readable | Writeable | Construct
    /// </details>
    /// <details><summary><h4>Container</h4></summary>
    ///
    ///
    /// #### `height`
    ///  The span of the container's children's [`priority`][struct@crate::TimelineElement#priority]
    /// values, which is the number of integers that lie between (inclusive)
    /// the minimum and maximum priorities found amongst the container's
    /// children (maximum - minimum + 1).
    ///
    /// Readable
    /// </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.
