Rate control output for a single frame.

Fields

qp: u8

Quantization parameter to use.

qp_f: f32

QP as floating point (before rounding).

target_bits: u64

Target bits for this frame.

min_bits: u64

Minimum bits (for underflow prevention).

max_bits: u64

Maximum bits (for overflow prevention).

drop_frame: bool

Whether to drop this frame.

force_keyframe: bool

Whether to force a keyframe.

qp_offsets: Option<Vec<f32>>

Block-level QP offsets for AQ.

lambda: f64

Lambda for RDO (rate-distortion optimization).

lambda_me: f64

Lambda for motion estimation.

Implementations

impl RcOutput

pub fn with_qp(qp: u8) -> Self

Create a new rate control output with the given QP.

pub fn drop() -> Self

Create output that drops the frame.

pub fn qp_to_lambda(qp: f32) -> f64

Calculate lambda from QP using standard formula. Lambda = 0.85 * 2^((QP-12)/3)

pub fn lambda_to_lambda_me(lambda: f64) -> f64

Calculate motion estimation lambda from lambda.

pub fn compute_lambda(&mut self)

Set lambda values based on QP.

Trait Implementations

impl Clone for RcOutput

fn clone(&self) -> RcOutput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RcOutput

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

Formats the value using the given formatter.

impl Default for RcOutput

fn default() -> RcOutput

Returns the “default value” for a type.
