Struct EncoderConfig 

pub struct EncoderConfig {
    pub width: usize,
    pub height: usize,
    pub profile: Profile,
    pub chroma: ChromaFormat,
    pub level_idc: u8,
    pub qp: u8,
    pub gop_size: u32,

    pub preset: Preset,
}

Configuration for an crate::Encoder.

Fields

width: usize

Picture width in luma samples. Arbitrary (not restricted to /16).

height: usize

Picture height in luma samples.

profile: Profile

Target profile. Only Profile::ConstrainedBaseline is implemented.

chroma: ChromaFormat

Chroma format. Only ChromaFormat::Yuv420 is implemented.

level_idc: u8

level_idc (e.g. 30 = level 3.0). Caller is responsible for choosing a level that admits the resolution/bitrate; not yet validated.

qp: u8

Quantization parameter (0..=51). With rate control off this is the fixed QP for every frame; with it on, the base/fallback QP and pic_init_qp.

gop_size: u32

Frames between IDR pictures. 1 = all-intra (every frame an IDR).

bitrate: u32

Target bitrate in bits per second. 0 disables rate control (constant QP); any positive value enables average-bitrate control, which varies the per-frame QP around qp to converge on this rate.

framerate: f32

Frame rate (frames per second), used by rate control to turn the bitrate target into a per-frame bit budget.

num_ref_frames: u32

Number of reference frames the encoder may use for P-pictures (1..=16). 1 keeps the single-reference bitstream; higher values let P-macroblocks pick an older reference (ref_idx), helping occlusion/periodic motion.

preset: Preset

Speed/quality trade-off. Defaults to Preset::Fast.

Implementations

impl EncoderConfig

pub fn new(width: usize, height: usize) -> Self

A minimal all-intra Constrained Baseline configuration at the given size.

pub fn mb_width(&self) -> usize

Picture width rounded up to whole macroblocks.

pub fn mb_height(&self) -> usize

Picture height rounded up to whole macroblocks.

Trait Implementations

impl Clone for EncoderConfig

fn clone(&self) -> EncoderConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncoderConfig

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

Formats the value using the given formatter.
