Description

GESCustomTimelineSource allows creating GESTimelineSource(s) without the need to subclass.

Its usage should be limited to testing and prototyping purposes.

Functions

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().

Parameters

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.

Parameters

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.
