Struct gstreamer_editing_services::Track
source · #[repr(transparent)]pub struct Track { /* private fields */ }
Expand description
A Track
acts an output source for a Timeline
. Each one
essentially provides an additional gst::Pad
for the timeline, with
property::Track::restriction-caps
capabilities. Internally, a track
wraps an nlecomposition
filtered by a capsfilter
.
A track will contain a number of TrackElement
-s, and its role is
to select and activate these elements according to their timings when
the timeline in played. For example, a track would activate a
Source
when its property::TimelineElement::start
is reached by outputting
its data for its property::TimelineElement::duration
. Similarly, a
Operation
would be activated by applying its effect to the source
data, starting from its property::TimelineElement::start
time and lasting for
its property::TimelineElement::duration
.
For most users, it will usually be sufficient to add newly created
tracks to a timeline, but never directly add an element to a track.
Whenever a Clip
is added to a timeline, the clip adds its
elements to the timeline’s tracks and assumes responsibility for
updating them.

Implementations
sourceimpl Track
impl Track
pub const NONE: Option<&'static Track> = None
sourcepub fn new(type_: TrackType, caps: &Caps) -> Track
pub fn new(type_: TrackType, caps: &Caps) -> Track
Creates a new track with the given track-type and caps.
If type_
is TrackType::VIDEO
, and caps
is a subset of
“video/x-raw(ANY)”, then a VideoTrack
is created. This will
automatically choose a gap creation method suitable for video data. You
will likely want to set property::Track::restriction-caps
separately. You may
prefer to use the VideoTrack::new()
method instead.
If type_
is TrackType::AUDIO
, and caps
is a subset of
“audio/x-raw(ANY)”, then a AudioTrack
is created. This will
automatically choose a gap creation method suitable for audio data, and
will set the property::Track::restriction-caps
to the default for
AudioTrack
. You may prefer to use the AudioTrack::new()
method
instead.
Otherwise, a plain Track
is returned. You will likely want to set
the property::Track::restriction-caps
and call
ges_track_set_create_element_for_gap_func()
on the returned track.
type_
The property::Track::track-type
for the track
caps
The property::Track::caps
for the track
Returns
A new track.
