Struct MvCost 

pub struct MvCost {
    pub lambda: f32,
    pub mv_weight: f32,
    pub ref_mv: MotionVector,
}

Motion vector cost calculator for rate-distortion optimization.

Fields

lambda: f32

Lambda for rate-distortion tradeoff.

mv_weight: f32

Weight for MV bits.

ref_mv: MotionVector

Reference motion vector for differential coding.
