GESCustomTimelineSource allows creating GESTimelineSource(s) without the need to subclass.
Its usage should be limited to testing and prototyping purposes.
typedef struct _GESCustomTimelineSource GESCustomTimelineSource;
Debugging custom timeline source
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().
|
the GESTimelineObject controlling the track object |
|
the GESTrackObject |
|
the GNonLin object that needs to be filled. |
|
the gpointer to optional user data |
Returns : |
TRUE if the implementer succesfully filled the gnlobj, else FALSE. |
GESCustomTimelineSource * ges_custom_timeline_source_new (GESFillTrackObjectUserFunc func,gpointer user_data);
Creates a new GESCustomTimelineSource.
|
The GESFillTrackObjectUserFunc that will be used to fill the track objects. |
|
a gpointer that will be used when func is called. |
Returns : |
The new GESCustomTimelineSource. |
