Struct PassOneResult

Source

pub struct PassOneResult {
    pub complexity_map: Vec<f64>,
    pub avg_complexity: f64,
    pub peak_complexity: f64,
    pub duration_analyzed_ms: u64,
}

Expand description

Results from the first pass of a two-pass encode.

Fields§

§complexity_map: Vec<f64>

Per-frame complexity scores (0.0 = very simple, 1.0 = very complex).

§avg_complexity: f64

Mean complexity across all analyzed frames.

§peak_complexity: f64

Peak (maximum) complexity observed.

§duration_analyzed_ms: u64

How many milliseconds of content were analyzed.

Implementations§

Source §

impl PassOneResult

Source

pub fn allocate_bits(&self, frame_idx: usize, total_bits: u64) -> u64

Allocates a bit count for the frame at frame_idx from the total bit budget.

Frames with higher complexity receive proportionally more bits. Falls back to an equal allocation if the sum of complexities is zero.

Source

pub fn is_complex_region(&self, idx: usize) -> bool

Returns true if the frame at frame_idx is in a complex region.

A region is considered complex if its complexity score is above the average by more than one standard deviation.

Source

pub fn complex_region_fraction(&self) -> f64

Returns the fraction of frames classified as complex regions.
