Struct gstreamer_editing_services::Timeline[−][src]

pub struct Timeline(_);

crate::Timeline is the central object for any multimedia timeline.

A timeline is composed of a set of crate::Track-s and a set of crate::Layer-s, which are added to the timeline using crate::prelude::TimelineExt::add_track() and crate::prelude::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 crate::gst::Pad.

Most usage of a timeline will likely only need a single [crate::AudioTrack] and/or a single [crate::VideoTrack]. You can create such a timeline with Self::new_audio_video(). After this, you are unlikely to need to work with the tracks directly.

A timeline’s layers contain crate::Clip-s, which in turn control the creation of crate::TrackElement-s, which are added to the timeline’s tracks. See [crate::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 crate::prelude::TimelineExt::move_layer().

Editing

See crate::TimelineElement for the various ways the elements of a timeline can be edited.

If you change the timing or ordering of a timeline’s crate::TimelineElement-s, then these changes will not actually be taken into account in the output of the timeline’s tracks until the crate::prelude::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 [crate::Source]-s may overlap in a crate::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 [crate::Source]-s, A and B, with start times startA and startB, and end times endA and endB, respectively. The start time refers to their [crate::TimelineElement:start], and the end time is their [crate::TimelineElement:start] + [crate::TimelineElement:duration]. These two sources overlap if:

they share the same [crate::TrackElement:track] (non None), which belongs to the timeline;
they share the same GES_TIMELINE_ELEMENT_LAYER_PRIORITY; and
startA < endB and startB < 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 [crate::Source]-s may overlap at that position. So triple or more overlaps are not allowed.

If you switch on [crate::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 crate::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 crate::prelude::TimelineExt::load_from_uri() and crate::prelude::TimelineExt::save_to_uri() methods that use the default format.

Playing

A timeline is a crate::gst::Bin with a source crate::gst::Pad for each of its tracks, which you can fetch with [crate::prelude::TimelineExt::get_pad_for_track()]. You will likely want to link these to some compatible sink crate::gst::Element-s to be able to play or capture the content of the timeline.

You can use a crate::Pipeline to easily preview/play the timeline’s content, or render it to a file.
