Struct BitrateTarget 

pub struct BitrateTarget {
    pub mode: RcMode,
    pub target_kbps: u32,
    pub min_kbps: u32,
    pub max_kbps: u32,
    pub quality_param: f32,
}

Describes the desired bitrate (or quality) target for an encoder.

Fields

mode: RcMode

Rate-control mode.

target_kbps: u32

Target bitrate in kbps (for CBR/VBR modes).

min_kbps: u32

Minimum bitrate in kbps (VBR lower bound; 0 = no limit).

max_kbps: u32

Maximum bitrate in kbps (VBR upper bound; 0 = no limit).

quality_param: f32

Quality parameter: CRF value or QP index (ignored for CBR/VBR).

Implementations

impl BitrateTarget

pub fn cbr(kbps: u32) -> Self

Create a CBR target at kbps kilobits per second.

pub fn vbr(target_kbps: u32, min_kbps: u32, max_kbps: u32) -> Self

Create a VBR target with min/max bounds.

pub fn crf(crf: f32) -> Self

Create a CRF target with a given CRF value (lower = higher quality).

pub fn effective_kbps(&self) -> u32

Returns the effective bitrate in kbps.

For quality-based modes, returns 0 (no hard bitrate target).

pub fn has_bitrate_budget(&self) -> bool

Returns true when a hard bitrate budget is set.

Trait Implementations

impl Clone for BitrateTarget

fn clone(&self) -> BitrateTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BitrateTarget

impl Debug for BitrateTarget

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

Formats the value using the given formatter.

impl PartialEq for BitrateTarget

fn eq(&self, other: &BitrateTarget) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
