Clip
§duration-limit
The maximum duration that can be currently set
for the clip, taking into account the in-point,
max-duration, active, and
track properties of its children, as well as any
time effects. If there is no limit, this will be set to
GST_CLOCK_TIME_NONE.
Note that whilst a clip has no children in any tracks, the limit will
be unknown, and similarly set to GST_CLOCK_TIME_NONE.
If the duration-limit would ever go below the current
duration of the clip due to a change in the above
variables, its duration will be set to the new
limit.
Readable
§layer
The layer this clip lies in.
If you want to connect to this property’s notify signal,
you should connect to it with g_signal_connect_after() since the
signal emission may be stopped internally.
Readable
§supported-formats
The TrackType-s that the clip supports, which it can create
TrackElement-s for. Note that this can be a combination of
TrackType flags to indicate support for several
track-type elements.
Readable | Writeable | Construct
Container
§height
The span of the container’s children’s priority
values, which is the number of integers that lie between (inclusive)
the minimum and maximum priorities found amongst the container’s
children (maximum - minimum + 1).
Readable
TimelineElement
§duration
The duration that the element is in effect for in the timeline (a time difference in nanoseconds using the time coordinates of the timeline). For example, for a source element, this would determine for how long it should output its internal content for. For an operation element, this would determine for how long its effect should be applied to any source content.
Readable | Writeable
§in-point
The initial offset to use internally when outputting content (in nanoseconds, but in the time coordinates of the internal content).
For example, for a VideoUriSource that references some media
file, the “internal content” is the media file data, and the
in-point would correspond to some timestamp in the media file.
When playing the timeline, and when the element is first reached at
timeline-time start, it will begin outputting the
data from the timestamp in-point onwards, until it reaches the
end of its duration in the timeline.
For elements that have no internal content, this should be kept as 0.
Readable | Writeable
§max-duration
The full duration of internal content that is available (a time difference in nanoseconds using the time coordinates of the internal content).
This will act as a cap on the in-point of the
element (which is in the same time coordinates), and will sometimes
be used to limit the duration of the element in
the timeline.
For example, for a VideoUriSource that references some media
file, this would be the length of the media file.
For elements that have no internal content, or whose content is
indefinite, this should be kept as GST_CLOCK_TIME_NONE.
Readable | Writeable | Construct
§name
The name of the element. This should be unique within its timeline.
Readable | Writeable | Construct
§parent
The parent container of the element.
Readable | Writeable
§priority
The priority of the element.
Readable | Writeable
§serialize
Whether the element should be serialized.
Readable | Writeable
§start
The starting position of the element in the timeline (in nanoseconds and in the time coordinates of the timeline). For example, for a source element, this would determine the time at which it should start outputting its internal content. For an operation element, this would determine the time at which it should start applying its effect to any source content.
Readable | Writeable
§timeline
The timeline that the element lies within.

fn find_track_element( &self, track: Option<&impl IsA<Track>>, type_: Type, ) -> Option<TrackElement>
Finds an element controlled by the clip. If
track is given,
then only the track elements in track are searched for. If type_ is
given, then this function searches for a track element of the given
type_. Read moresource§fn find_track_elements(

fn find_track_elements( &self, track: Option<&impl IsA<Track>>, track_type: TrackType, type_: Type, ) -> Vec<TrackElement>
Finds the
TrackElement-s controlled by the clip that match the
given criteria. If track is given as None and track_type is given as
TrackType::UNKNOWN, then the search will match all elements in any
track, including those with no track, and of any
track-type. Otherwise, if track is not None, but
track_type is TrackType::UNKNOWN, then only the track elements in
track are searched for. Otherwise, if track_type is not
TrackType::UNKNOWN, but track is None, then only the track
elements whose track-type matches track_type are
searched for. Otherwise, when both are given, the track elements that
match either criteria are searched for. Therefore, if you wish to
only find elements in a specific track, you should give the track as
track, but you should not give the track’s track-type as
track_type because this would also select elements from other tracks
of the same type. Read moresource§fn duration_limit(&self) -> ClockTime

fn top_effect_index(&self, effect: &impl IsA<BaseEffect>) -> i32
Gets the internal index of an effect in the clip. The index of effects
in a clip will run from 0 to n-1, where n is the total number of
effects. If two effects share the same
track, the
effect with the numerically lower index will be applied to the source
data after the other effect, i.e. output data will always flow from
a higher index effect to a lower index effect. Read morefn top_effect_position(&self, effect: &impl IsA<BaseEffect>) -> i32

fn ungroup(self, recursive: bool) -> Vec<Container>
Ungroups the container by splitting it into several containers
containing various children of the original. The rules for how the
container splits depends on the subclass. A
Group will simply split
into its children. A Clip will split into one Clip per
TrackType it overlaps with (so an audio-video clip will split into
an audio clip and a video clip), where each clip contains all the
TrackElement-s from the original clip with a matching
track-type. Read moresource§fn height(&self) -> u32
fn height(&self) -> u32
The span of the container’s children’s
priority
values, which is the number of integers that lie between (inclusive)
the minimum and maximum priorities found amongst the container’s
children (maximum - minimum + 1).source§fn connect_child_added<F: Fn(&Self, &TimelineElement) + 'static>(

Edits the element within its timeline by adjusting its
start, duration or

other elements in the timeline. See EditMode for details about each
edit mode. An edit may fail if it would place one of these properties
out of bounds, or if it would place the timeline in an unsupported

Paste an element inside the same timeline and layer as

self is not placed in the timeline, instead a new element is created,

the point of copying and pasting. Read moresource§fn remove_child_property(
