Struct FirstPassFrameStats 

pub struct FirstPassFrameStats {
    pub frame_index: u64,
    pub intra_cost: f32,
    pub inter_cost: f32,
    pub intra_inter_ratio: f32,
    pub mean_sad: f32,
    pub key_frame_bits: u64,
    pub is_scene_change: bool,
}

Per-frame statistics recorded during the first encoding pass.

Fields

frame_index: u64

Frame index (display order).

intra_cost: f32

Mean intra cost (bits per pixel at a reference QP).

inter_cost: f32

Mean inter cost (bits per pixel for the best motion prediction).

intra_inter_ratio: f32

Intra/inter cost ratio; values > 1.0 indicate scene-change candidates.

mean_sad: f32

Motion-compensated average block SAD.

key_frame_bits: u64

Estimated number of bits if encoded as a key frame.

is_scene_change: bool

Whether this frame was marked as a scene change in the first pass.

Implementations

impl FirstPassFrameStats

pub fn new(frame_index: u64, intra_cost: f32, inter_cost: f32) -> Self

Create a minimal stats record for a frame.

pub fn complexity_weight(&self) -> f32

Effective complexity weight for bit allocation.

Uses the inter cost as the primary signal; scene-change frames get a boost so that the I-frame receives proportionally more bits.

Trait Implementations

impl Clone for FirstPassFrameStats

fn clone(&self) -> FirstPassFrameStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FirstPassFrameStats

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

Formats the value using the given formatter.
