    /// VideoAggregator can accept AYUV, ARGB and BGRA video streams. For each of the requested
    /// sink pads it will compare the incoming geometry and framerate to define the
    /// output parameters. Indeed output video frames will have the geometry of the
    /// biggest incoming video stream and the framerate of the fastest incoming one.
    ///
    /// VideoAggregator will do colorspace conversion.
    ///
    /// Zorder for each input stream can be configured on the
    /// [`VideoAggregatorPad`][crate::VideoAggregatorPad].

    /// ## Properties
    ///
    ///
    /// #### `force-live`
    ///  Causes the element to aggregate on a timeout even when no live source is
    /// connected to its sinks. See [`min-upstream-latency`][struct@crate::gst_base::Aggregator#min-upstream-latency] for a
    /// companion property: in the vast majority of cases where you plan to plug in
    /// live sources with a non-zero latency, you should set it to a non-zero value.
    ///
    /// Readable | Writeable | Construct Only
    /// <details><summary><h4>Aggregator</h4></summary>
    ///
    ///
    /// #### `emit-signals`
    ///  Enables the emission of signals such as [`samples-selected`][struct@crate::gst_base::Aggregator#samples-selected]
    ///
    /// Readable | Writeable
    ///
    ///
    /// #### `latency`
    ///  Readable | Writeable
    ///
    ///
    /// #### `min-upstream-latency`
    ///  Force minimum upstream latency (in nanoseconds). When sources with a
    /// higher latency are expected to be plugged in dynamically after the
    /// aggregator has started playing, this allows overriding the minimum
    /// latency reported by the initial source(s). This is only taken into
    /// account when larger than the actually reported minimum latency.

    ///
    /// #### `parent`
    ///  The parent of the object. Please note, that when changing the 'parent'
    /// property, we don't emit [`notify`][struct@crate::glib::Object#notify] and [`deep-notify`][struct@crate::gst::Object#deep-notify]
    /// signals due to locking issues. In some cases one can use
    /// `GstBin::element-added` or `GstBin::element-removed` signals on the parent to
    /// achieve a similar effect.
