Struct Ladder 

pub struct Ladder {
    pub rungs: Vec<Rung>,
}

Ordered set of rungs from lowest to highest quality.

Fields

rungs: Vec<Rung>

Rungs ordered by ascending bitrate.

Implementations

impl Ladder

pub fn bitrate_range(&self) -> (f64, f64)

Returns the (lowest, highest) bitrate in kbps, or (0.0, 0.0) if empty.

pub fn quality_range(&self) -> (f64, f64)

Returns the (lowest, highest) VMAF quality, or (0.0, 0.0) if empty.

pub fn savings(&self, fixed_bitrate: f64) -> f64

Percent bitrate savings of the top rung versus a fixed top-rung bitrate (kbps).

Returns 0.0 if the ladder is empty or the top rung is not cheaper.
