Struct TranscodeSettings

    pub mode: Option<Mode>,
    pub rungs: Vec<(u32, u32)>,
    pub ladder: bool,
    pub max_short_side: Option<u32>,

    pub decode_gpu: Option<u32>,
    pub width: Option<u32>,
    pub height: Option<u32>,
    pub filters: Vec<VideoFilter>,
}

Every optional transcode knob, surface-agnostic. All-None/empty is “use the defaults” (source-resolution single file, AV1 + audio passthrough, SDR).

Fields

mode: Option<Mode>

rungs: Vec<(u32, u32)>

Explicit rungs as (width, height). Wins over ladder / width.

ladder: bool

Derive a standard ABR ladder from the source.

max_short_side: Option<u32>

segment_seconds: Option<f32>

crf: Option<u8>

speed: Option<u8>

audio: Option<AudioPolicy>

color: Option<ColorPolicy>

bit_depth: Option<BitDepth>

seam: Option<ChunkSeamMode>

max_fps: Option<f64>

gpu: Option<u32>

Pin encode to one GPU index.

gpu_family: Option<GpuFamily>

Restrict encode to one vendor family.

single_gpu: bool

Use a single GPU (serial), the first available.

decode_gpu: Option<u32>

Pin the decode pump to a GPU index.

width: Option<u32>

Single-output width/height (the pipe/ipc scaling knobs). Used only when neither rungs nor ladder is set; defaults to the source size.

height: Option<u32>

filters: Vec<VideoFilter>

Video filter chain (crop/pad/flip/rotate/grayscale) applied before per-rung scaling. The canonical structured form; string surfaces parse codec::filter::parse_chain at the edge.

Implementations

impl TranscodeSettings

pub fn into_spec(self, src_w: u32, src_h: u32) -> Result<OutputSpec>

Build an OutputSpec from these settings against a source resolution. This is the single spec-building implementation for all surfaces.

pub fn apply_kv(&mut self, key: &str, val: &str) -> Result<()>

Apply one key=value setting (the IPC header / generic string form). Keys mirror the CLI flags. Unknown keys error.

pub fn parse_kv_line(line: &str) -> Result<Self>

Parse a whole key=value key=value … line into settings.

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for TranscodeSettings

fn clone(&self) -> TranscodeSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TranscodeSettings

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

Formats the value using the given formatter.

impl Default for TranscodeSettings

fn default() -> TranscodeSettings

Returns the “default value” for a type.
