[−][src]Struct gstreamer_editing_services::Timeline
Timeline is the central object for any multimedia timeline.
A timeline is composed of a set of Track-s and a set of
Layer-s, which are added to the timeline using
TimelineExt::add_track and TimelineExt::append_layer, respectively.
The contained tracks define the supported types of the timeline
and provide the media output. Essentially, each track provides an
additional source gst::Pad.
Most usage of a timeline will likely only need a single AudioTrack
and/or a single VideoTrack. You can create such a timeline with
Timeline::new_audio_video. After this, you are unlikely to need to
work with the tracks directly.
A timeline's layers contain Clip-s, which in turn control the
creation of TrackElement-s, which are added to the timeline's
tracks. See Timeline::select-tracks-for-object if you wish to have
more control over which track a clip's elements are added to.
The layers are ordered, with higher priority layers having their
content prioritised in the tracks. This ordering can be changed using
TimelineExt::move_layer.
Editing
See TimelineElement for the various ways the elements of a timeline
can be edited.
If you change the timing or ordering of a timeline's
TimelineElement-s, then these changes will not actually be taken
into account in the output of the timeline's tracks until the
TimelineExt::commit method is called. This allows you to move its
elements around, say, in response to an end user's mouse dragging, with
little expense before finalising their effect on the produced data.
Overlaps and Auto-Transitions
There are certain restrictions placed on how Source-s may overlap
in a Track that belongs to a timeline. These will be enforced by
GES, so the user will not need to keep track of them, but they should
be aware that certain edits will be refused as a result if the overlap
rules would be broken.
Consider two Source-s, A and B, with start times startA and
startB, and end times endA and endB, respectively. The start
time refers to their TimelineElement:start, and the end time is
their TimelineElement:start + TimelineElement:duration. These
two sources overlap if:
- they share the same
TrackElement:track(nonNone), which belongs to the timeline; - they share the same
GES_TIMELINE_ELEMENT_LAYER_PRIORITY; and startA < endBandstartB < endA.
Note that when startA = endB or startB = endA then the two sources
will touch at their edges, but are not considered overlapping.
If, in addition, startA < startB < endA, then we can say that the
end of A overlaps the start of B.
If, instead, startA <= startB and endA >= endB, then we can say
that A fully overlaps B.
The overlap rules for a timeline are that:
- One source cannot fully overlap another source.
- A source can only overlap the end of up to one other source at its start.
- A source can only overlap the start of up to one other source at its end.
The last two rules combined essentially mean that at any given timeline
position, only up to two Source-s may overlap at that position. So
triple or more overlaps are not allowed.
If you switch on Timeline:auto-transition, then at any moment when
the end of one source (the first source) overlaps the start of another
(the second source), a TransitionClip will be automatically created
for the pair in the same layer and it will cover their overlap. If the
two elements are edited in a way such that the end of the first source
no longer overlaps the start of the second, the transition will be
automatically removed from the timeline. However, if the two sources
still overlap at the same edges after the edit, then the same
transition object will be kept, but with its timing and layer adjusted
accordingly.
Saving
To save/load a timeline, you can use the TimelineExt::load_from_uri
and TimelineExt::save_to_uri methods that use the default format.
Playing
A timeline is a gst::Bin with a source gst::Pad for each of its
tracks, which you can fetch with TimelineExt::get_pad_for_track. You
will likely want to link these to some compatible sink gst::Element-s to
be able to play or capture the content of the timeline.
You can use a Pipeline to easily preview/play the timeline's
content, or render it to a file.
