GESFillTrackObjectUserFunc ()

gboolean            (*GESFillTrackObjectUserFunc)       (GESTimelineObject *object,
                                                         GESTrackObject *trobject,
                                                         GstElement *gnlobj,
                                                         gpointer user_data);

A function that will be called when the GNonLin object of a corresponding track object needs to be filled.

The implementer of this function shall add the proper GstElement to gnlobj using gst_bin_add().

object :

the GESTimelineObject controlling the track object

trobject :

the GESTrackObject

gnlobj :

the GNonLin object that needs to be filled.

user_data :

the gpointer to optional user data

Returns :

TRUE if the implementer succesfully filled the gnlobj, else FALSE.

ges_custom_timeline_source_new ()

GESCustomTimelineSource * ges_custom_timeline_source_new
                                                        (GESFillTrackObjectUserFunc func,
                                                         gpointer user_data);

Creates a new GESCustomTimelineSource.

func :

The GESFillTrackObjectUserFunc that will be used to fill the track objects.

user_data :

a gpointer that will be used when func is called.

Returns :

The new GESCustomTimelineSource.
