}

Aggregate (pooled) quality scores, with optional per-frame breakdown.

Each score is 0.0 when its metric was not requested or is unavailable.

Fields

vmaf: f64

Mean VMAF score.

psnr: f64

Mean luma (Y) PSNR (dB).

psnr_u: f64

Mean Cb/U-plane PSNR (dB); 0.0 when per-component PSNR is unavailable.

psnr_v: f64

Mean Cr/V-plane PSNR (dB); 0.0 when per-component PSNR is unavailable.

psnr_avg: f64

Weighted PSNR (6·Y + U + V) / 8 (dB); falls back to luma when chroma is absent.

ssim: f64

Mean SSIM.

ssimulacra2: f64

SSIMULACRA2 score (mean over sampled frames).

butteraugli: f64

Butteraugli distance (mean over sampled frames).

ms_ssim: f64

Mean multi-scale SSIM; 0.0 when not requested.

vif: f64

Mean VIF (visual information fidelity); computed alongside VMAF.

cambi: f64

Mean CAMBI banding score (lower is better); 0.0 when not requested.

xpsnr: f64

Mean weighted XPSNR (6·Y + U + V) / 8 (dB); 0.0 when not requested.

pooled: Pooled

Distribution statistics (mean, harmonic mean, percentiles, …) per metric.

frames: Vec<FrameResult>

Per-frame scores; populated only when MeasureOpts::per_frame is set.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Result

fn default() -> Result

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Result

where Result: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,
