GESTimeline is the central object for any multimedia timeline.
Contains a list of GESTimelineLayer which users should use to arrange the various timeline objects through time.
The output type is determined by the GESTrack that are set on the GESTimeline.
To save/load a timeline, you can use the ges_timeline_load_from_uri()
and
ges_timeline_save_to_uri()
methods to use the default format. If you wish
to specify the format to save/load the timeline from, please consult the
documentation about GESFormatter.
GESTimeline *
ges_timeline_new_audio_video (void
);
Creates a new GESTimeline containing a raw audio and a raw video track.
GESTimeline *
ges_timeline_new_from_uri (gchar *uri
);
Creates a timeline from the given URI.
gboolean ges_timeline_add_layer (GESTimeline *timeline
,GESTimelineLayer *layer
);
Add the layer to the timeline. The reference to the layer
will be stolen
by the timeline
.
gboolean ges_timeline_remove_layer (GESTimeline *timeline
,GESTimelineLayer *layer
);
Removes the layer from the timeline. The reference that the timeline
holds on
the layer will be dropped. If you wish to use the layer
after calling this
method, you need to take a reference before calling.
gboolean ges_timeline_add_track (GESTimeline *timeline
,GESTrack *track
);
Add a track to the timeline. The reference to the track will be stolen by the pipeline.
gboolean ges_timeline_remove_track (GESTimeline *timeline
,GESTrack *track
);
Remove the track
from the timeline
. The reference stolen when adding the
track
will be removed. If you wish to use the track
after calling this
function you must ensure that you have a reference to it.
gboolean ges_timeline_load_from_uri (GESTimeline *timeline
,gchar *uri
);
Loads the contents of URI into the given timeline.
gboolean ges_timeline_save_to_uri (GESTimeline *timeline
,gchar *uri
);
Saves the timeline to the given location
GList *
ges_timeline_get_tracks (GESTimeline *timeline
);
Returns the list of GESTrack used by the Timeline.
A list of GESTrack. The caller should unref each track once he is done with them.
[transfer full][element-type GESTrack]
GList *
ges_timeline_get_layers (GESTimeline *timeline
);
Get the list of GESTimelineLayer present in the Timeline.
the list of GESTimelineLayer present in the Timeline. The caller should unref each Layer once he is done with them.
[transfer full][element-type GESTimelineLayer]
GESTrack * ges_timeline_get_track_for_pad (GESTimeline *timeline
,GstPad *pad
);
Search the GESTrack corresponding to the given timeline
's pad
.
