Struct Ffv1Config 

pub struct Ffv1Config {
    pub level: Ffv1Level,
    pub coder: Ffv1Coder,
    pub slice_count: u8,
    pub context_model: u8,
    pub checksum: bool,
}

FFV1 lossless video codec configuration.

Fields

level: Ffv1Level

FFV1 level (1 or 3).

coder: Ffv1Coder

Entropy coder selection.

slice_count: u8

Number of slices for multithreaded encoding (1, 4, 9, 16, 24).

context_model: u8

Context model complexity (0=simple, 1=complex/better compression).

checksum: bool

Enable per-slice CRC checksums for error detection.

Implementations

impl Ffv1Config

pub fn new() -> Self

Creates a new FFV1 configuration with sensible defaults.

pub fn lossless_archive() -> Self

Best-compression archival preset.

Uses Level 3, Range coder, 16 slices, complex context model, and checksums. Ideal for long-term preservation where file size and integrity matter most.

pub fn lossless_fast() -> Self

Fastest lossless encoding preset.

Uses Level 1, Golomb-Rice coder, 4 slices, simple context model, no checksums. Ideal for fast ingest or intermediate encoding.

pub fn with_slices(self, count: u8) -> Self

Sets the number of encoding slices.

Valid values: 1, 4, 9, 16, 24. More slices enable better multithreading.

pub fn build(self) -> CodecConfig

Builds a CodecConfig from this FFV1 configuration.

Trait Implementations

impl Clone for Ffv1Config

fn clone(&self) -> Ffv1Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ffv1Config

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

Formats the value using the given formatter.

impl Default for Ffv1Config

fn default() -> Self

Returns the “default value” for a type.
