Struct Quality 

pub struct Quality {
    pub crf: Option<u8>,
    pub speed_preset: Option<u8>,
    pub target: QualityTarget,
    pub tier: SpeedTier,
    pub keyframe_interval: Option<u32>,
}

Encoder quality knobs for a rung.

Fields

crf: Option<u8>

Constant rate factor in the encoder-native scale (rav1e/NVENC 0..=255). None derives the quantizer from Quality::target.

speed_preset: Option<u8>

Encoder-native speed preset. None derives it from Quality::tier.

target: QualityTarget

Perceptual quality target (used when crf is None).

tier: SpeedTier

Speed/efficiency tier (used when speed_preset is None).

keyframe_interval: Option<u32>

GOP length in frames. None → 2 × frame_rate (a 2-second GOP).

Implementations

impl Quality

pub fn crf(crf: u8) -> Self

A constant-rate-factor quality.

pub fn target(target: QualityTarget) -> Self

A perceptual-target quality.

Trait Implementations

impl Clone for Quality

fn clone(&self) -> Quality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Quality

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

Formats the value using the given formatter.

impl Default for Quality

fn default() -> Self

Returns the “default value” for a type.
