GObject +----GstObject +----GstElement +----GstBin +----GnlObject +----GnlComposition
A GnlComposition contains GnlObjects such as GnlSources and GnlOperations, and connects them dynamically to create a composition timeline.
"update"
property"update" gboolean : Read / Write
If TRUE
, then all modifications to objects within the composition will
cause a internal pipeline update (if required).
If FALSE
, then only the composition's start/duration/stop properties
will be updated, and the internal pipeline will only be updated when the
property is set back to TRUE
.
It is recommended to temporarily set this property to FALSE
before doing
more than one modification in the composition (like adding/moving/removing
several objects at once) in order to speed up the process, and then setting
back the property to TRUE
when done.
Default value: TRUE
