list_filter

function list_filter(list:[Gst.ElementFactory], caps:Gst.Caps, direction:Gst.PadDirection, subsetonly:Boolean):[Gst.ElementFactory] {
    // Gjs wrapper for gst_element_factory_list_filter()
}

Filter out all the elementfactories in list that can handle caps in the given direction.

If subsetonly is true, then only the elements whose pads templates are a complete superset of caps will be returned. Else any element whose pad templates caps can intersect with caps will be returned.

list: a GLib.List of Gst.ElementFactory to filter
caps: a Gst.Caps
direction: a Gst.PadDirection to filter on
subsetonly: whether to filter on caps subsets or not.
Returns: a GLib.List of Gst.ElementFactory elements that match the given requisits. Use #gst_plugin_feature_list_free after usage.
