Fields

rung_idx: usize

width: u32

height: u32

frame_rate: f64

quality: u8

Legacy CRF escape hatch (u8::MAX = derive from target).

speed_preset: u8

Speed preset escape hatch (u8::MAX = derive from tier).

target: QualityTarget

Perceptual quality target (used when quality is the sentinel).

tier: SpeedTier

Speed tier (used when speed_preset is the sentinel).

threads: usize

gpu_index: Option<u32>

gpu_vendor: Option<GpuVendor>

output_color_metadata: ColorMetadata

Resolved output color metadata + pixel format (the encoder’s input format and bitstream signaling). The engine computes these from the OutputSpec’s ColorPolicy / BitDepth via resolve_output, so the worker no longer folds HDR→SDR itself — it just encodes to this format.

output_pixel_format: PixelFormat

constant_qp: bool

Prefer constant-QP rate control (seam-flat chunked single-file under ChunkSeamMode::ParallelConstQp). Forwarded to EncoderConfig.constant_qp.

timescale: u32

per_frame_ticks: u32

keyframe_interval: u32

segment_target_ticks: u64

output_dir: PathBuf

rung_invariant: Arc<RwLock<Option<RungCodecInvariant>>>

Shared per-rung codec invariant slot. First worker on the rung SETS it; helpers (any vendor) COMPARE on their first packet. On mismatch the helper requeues its chunk and exits cleanly so the run continues without it — never aborts mission-critical jobs. See validate_or_set_rung_invariant + the requeue path in run_encoder_worker_blocking.

Trait Implementations

impl Clone for EncoderWorkerConfig

fn clone(&self) -> EncoderWorkerConfig
