Struct BitrateEstimator 

pub struct BitrateEstimator {
    pub mode: RateControlMode,
    pub history: Vec<u32>,
}

Tracks per-frame sizes and derives a rolling bitrate estimate.

Fields

mode: RateControlMode

Rate-control mode in use.

history: Vec<u32>

History of frame sizes in bytes (most recent last).

Implementations

impl BitrateEstimator

pub fn new(mode: RateControlMode) -> Self

Creates a new estimator for the given mode.

pub fn add_frame_size_bytes(&mut self, size: u32)

Appends a frame’s encoded size (in bytes) to the history.

pub fn current_kbps(&self, fps: f32) -> f32

Estimates the current bitrate in kbps given the encoding frame rate.

Returns 0.0 if no frames have been recorded or fps is zero/negative.

pub fn variance(&self) -> f32

Returns the variance of frame sizes (in bytes²).

Returns 0.0 if fewer than two frames have been recorded.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for BitrateEstimator

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