Struct Vp9Options 

pub struct Vp9Options {
    pub cpu_used: i8,
    pub cq_level: Option<u8>,
    pub tile_columns: u8,
    pub tile_rows: u8,
    pub row_mt: bool,
}

VP9 (libvpx-vp9) per-codec options.

Fields

cpu_used: i8

Encoder speed/quality trade-off: -8 = best quality / slowest, 8 = fastest.

cq_level: Option<u8>

Constrained Quality level (0–63).

Some(q) enables CQ mode: sets bit_rate = 0 and applies q as the crf option, producing variable-bitrate output governed by perceptual quality. None uses the bitrate mode configured on the builder.

tile_columns: u8

Log2 number of tile columns (0–6).

tile_rows: u8

Log2 number of tile rows (0–6).

row_mt: bool

Enable row-based multithreading for better CPU utilisation.
