Struct Vp9Config 

pub struct Vp9Config { /* private fields */ }

VP9 specific configuration.

Implementations

impl Vp9Config

pub fn new() -> Self

Creates a new VP9 configuration.

pub fn crf(crf_value: u8) -> Self

Creates a VP9 configuration in CRF (constant quality) mode.

CRF range for VP9 is 0–63; lower values produce higher quality. Typical values: 31 (good quality), 33 (balanced), 41 (lower quality).

pub fn cpu_used(self, cpu_used: u8) -> Self

Sets the CPU used (0-8, lower = slower/better).

pub fn tile_columns(self, columns: u8) -> Self

Sets the tile columns for parallel encoding (0–6, value is log2 of column count).

pub fn with_tile_columns(self, cols: u8) -> Self

Sets the tile columns for parallel encoding via builder pattern (0–6).

pub fn tile_rows(self, rows: u8) -> Self

Sets the tile rows (for parallel encoding).

pub fn frame_parallel(self, enable: bool) -> Self

Sets the frame parallel encoding.

pub fn with_frame_parallel(self, enabled: bool) -> Self

Enables or disables frame-parallel decoding hint via builder pattern.

pub fn auto_alt_ref(self, frames: u8) -> Self

Sets the auto alt reference frames.

pub fn lag_in_frames(self, lag: u32) -> Self

Sets the lag in frames (0–25).

Larger values allow better quality at the cost of encoding latency.

pub fn with_lag_in_frames(self, frames: u8) -> Self

Sets lag in frames via builder pattern (0–25).

pub fn row_mt(self, enable: bool) -> Self

Enables row-based multi-threading.

pub fn with_row_mt(self, enabled: bool) -> Self

Enables or disables row-based multi-threading via builder pattern.

pub fn screen_content() -> Self

Screen content encoding preset.

Optimised for screen recordings: fast cpu-used, tile columns for parallelism, and row-mt for throughput. Uses CRF 33 as a balanced starting point.

pub fn build(self) -> CodecConfig

Converts to base codec config.
