[−][src]Struct gstreamer_editing_services::Group
A Group
controls one or more Container
-s (usually Clip
-s,
but it can also control other Group
-s). Its children must share
the same Timeline
, but can otherwise lie in separate Layer
-s
and have different timings.
To initialise a group, you may want to use Container::group
,
and similarly use GESContainerExt::ungroup
to dispose of it.
A group will maintain the relative TimelineElement:start
times of
its children, as well as their relative layer Layer:priority
.
Therefore, if one of its children has its TimelineElement:start
set, all other children will have their TimelineElement:start
shifted by the same amount. Similarly, if one of its children moves to
a new layer, the other children will also change layers to maintain the
difference in their layer priorities. For example, if a child moves
from a layer with Layer:priority
1 to a layer with priority 3, then
another child that was in a layer with priority 0 will move to the
layer with priority 2.
The Group:start
of a group refers to the earliest start
time of its children. If the group's Group:start
is set, all the
children will be shifted equally such that the earliest start time
will match the set value. The Group:duration
of a group is the
difference between the earliest start time and latest end time of its
children. If the group's Group:duration
is increased, the children
whose end time matches the end of the group will be extended
accordingly. If it is decreased, then any child whose end time exceeds
the new end time will also have their duration decreased accordingly.
A group may span several layers, but for methods such as
TimelineElementExt::get_layer_priority
and
TimelineElementExt::edit
a group is considered to have a layer
priority that is the highest Layer:priority
(numerically, the
smallest) of all the layers it spans.

Implementations
impl Group
[src]
pub fn new() -> Group
[src]
Created a new empty group. You may wish to use
Container::group
instead, which can return a different
Container
subclass if possible.
Returns
The new empty group.
