Trait containing all Layer methods.

Layer

Required methods

See add_asset_full(), which also gives an error.

asset

The asset to extract the new clip from

start

The property::TimelineElement::start value to set on the new clip If start == GST_CLOCK_TIME_NONE``, it will be added to the end of self, i.e. it will be set to self’s duration

inpoint

The property::TimelineElement::in-point value to set on the new clip

duration

The property::TimelineElement::duration value to set on the new clip

track_types

The property::Clip::supported-formats to set on the the new clip, or TrackType::UNKNOWN to use the default

Returns

The newly created clip.
