Struct EncodeMetrics 

pub struct EncodeMetrics {
    pub name: String,
    pub encode_time: Duration,
    pub file_size_bytes: u64,
    pub bitrate_kbps: f64,
    pub duration_secs: f64,

}

Quality and performance metrics from a single encode run.

Fields

name: String

Candidate name.

encode_time: Duration

Wall-clock encoding time.

file_size_bytes: u64

Encoded file size in bytes.

bitrate_kbps: f64

Average bitrate in kbps (computed from size and duration).

duration_secs: f64

Content duration in seconds.

speed_factor: f64

Encoding speed factor (content_duration / encode_time).

psnr_db: Option<f64>

Peak signal-to-noise ratio (dB) — None if not measured.

ssim: Option<f64>

Structural similarity (0.0–1.0) — None if not measured.

vmaf: Option<f64>

Video Multi-Method Assessment Fusion score — None if not measured.

Implementations

impl EncodeMetrics

pub fn new( name: impl Into<String>, encode_time: Duration, file_size_bytes: u64, duration_secs: f64, ) -> Self

Creates a new EncodeMetrics from timing / size data alone.

pub fn with_psnr(self, psnr: f64) -> Self

Attaches PSNR.

pub fn with_ssim(self, ssim: f64) -> Self

Attaches SSIM.

pub fn with_vmaf(self, vmaf: f64) -> Self

Attaches VMAF.

pub fn bits_per_pixel_per_frame( &self, width: u32, height: u32, fps_num: u32, fps_den: u32, ) -> f64

Returns a “BD-Rate proxy” — bits-per-pixel-per-frame.

Lower is more efficient.

Trait Implementations

impl Clone for EncodeMetrics

fn clone(&self) -> EncodeMetrics

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EncodeMetrics

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

Formats the value using the given formatter.
