Required Methods

fn add_asset(
    &self,
    asset: &impl IsA<Asset>,
    start: impl Into<Option<ClockTime>>,
    inpoint: impl Into<Option<ClockTime>>,
    duration: impl Into<Option<ClockTime>>,
    track_types: TrackType
) -> Result<Clip, BoolError>

See add_asset_full(), which also gives an error.

asset

The asset to extract the new clip from

start

The 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 in-point value to set on the new clip

duration

The duration value to set on the new clip

track_types

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

Returns

The newly created clip.
