Gst.Object.prototype.sync_values

function sync_values(timestamp:Gst.ClockTime):Boolean {
    // Gjs wrapper for gst_object_sync_values()
}

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.
