Struct VideoLayer 

pub struct VideoLayer {
    pub source: PathBuf,
    pub x: AnimatedValue<f64>,
    pub y: AnimatedValue<f64>,
    pub scale_x: AnimatedValue<f64>,
    pub scale_y: AnimatedValue<f64>,
    pub rotation: AnimatedValue<f64>,
    pub opacity: AnimatedValue<f64>,
    pub z_order: u32,
    pub time_offset: Duration,
    pub in_point: Option<Duration>,
    pub out_point: Option<Duration>,
}

A single video layer in a MultiTrackComposer composition.

Layers are composited in ascending z_order, with 0 rendered first (bottom of the stack).

The x, y, scale_x, scale_y, rotation, and opacity fields accept either a constant (AnimatedValue::Static) or a time-varying keyframe track (AnimatedValue::Track). The initial filter graph is built from the value at Duration::ZERO; per-frame updates are added in issue #363.

Fields

source: PathBuf

Source media file path.

x: AnimatedValue<f64>

X offset on the canvas in pixels (top-left origin).

y: AnimatedValue<f64>

Y offset on the canvas in pixels.

scale_x: AnimatedValue<f64>

Horizontal scale factor applied to the source frame (1.0 = original width).

scale_y: AnimatedValue<f64>

Vertical scale factor applied to the source frame (1.0 = original height).

rotation: AnimatedValue<f64>

Clockwise rotation in degrees (0.0 = no rotation).

opacity: AnimatedValue<f64>

Opacity (0.0 = fully transparent, 1.0 = fully opaque).

z_order: u32

Compositing order (0 = bottom layer; higher values render on top).

time_offset: Duration

Start offset on the output timeline (Duration::ZERO = at the beginning).

in_point: Option<Duration>

Optional trim start within the source file.

out_point: Option<Duration>

Optional trim end within the source file.

Trait Implementations
