Struct RdoEngine

Source

pub struct RdoEngine { /* private fields */ }

Expand description

RDO engine for mode decision.

Implementations§

Source §

impl RdoEngine

Source

pub fn new(config: &OptimizerConfig) -> OxiResult<Self>

Creates a new RDO engine.

Source

pub fn calculate_cost(&self, distortion: f64, rate: f64, qp: u8) -> f64

Calculates the rate-distortion cost for a decision.

§Parameters

distortion: Distortion metric (SSE, SAD, SATD)
rate: Bit rate for this decision
qp: Quantization parameter

§Returns

The RD cost: distortion + lambda * rate

Source

pub fn evaluate_modes<F>( &self, candidates: &[ModeCandidate], eval_fn: F, ) -> RdoResult
where F: Fn(&ModeCandidate) -> (f64, f64) + Send + Sync,

Evaluates multiple mode decisions and returns the best one.

Source

pub fn optimization_level(&self) -> OptimizationLevel

Gets the optimization level.

Source

pub fn should_perform_full_rdo(&self) -> bool

Checks if the engine should perform full RDO.

Source

pub fn should_use_satd(&self) -> bool

Checks if the engine should use SATD instead of SAD.
