Struct CrfOptimizer

Source

pub struct CrfOptimizer;

Expand description

CRF optimizer using binary search over the CRF space.

Implementations§

Source §

impl CrfOptimizer

Source

pub fn new() -> Self

Creates a new CrfOptimizer.

Source

pub fn find_optimal( target: &QualityTarget, crf_range: CrfRange, content_complexity: f32, ) -> CrfOptimizerResult

Finds the optimal CRF for the given quality target using binary search.

The bitrate model is: bitrate = complexity * base * 2^((28 - crf) / 6). Higher CRF → lower quality → lower bitrate. Searches for the lowest CRF (best quality) that keeps bitrate ≤ max_bitrate_kbps.

Source

pub fn estimate_psnr(crf: u8, _complexity: f32) -> f32

Estimates PSNR for a given CRF.

Simple heuristic: lower CRF → higher PSNR. CRF=0 → ~50dB, CRF=51 → ~30dB.
