Configuration for one decode pump.

Fields

codec_name: String

Source video codec label (e.g. "h264").

info_for_decoder: StreamInfo

Stream info handed to the decoder.

source_color_metadata: ColorMetadata

Source color metadata (drives HDR-aware tonemap vs SDR passthrough).

source_pixel_format: PixelFormat

Source pixel format.

needs_downsample: bool

Whether to run the 4:4:4 → 4:2:0 downsample per frame.

tonemap_to_sdr: bool

Tonemap policy (from the OutputSpec): when true, HDR (PQ/HLG) sources are mapped down to 8-bit SDR BT.709; when false, the source color/transfer/bit-depth passes through unchanged. The pump does not decide this on its own — the caller sets it from the spec’s ColorPolicy.

gpu_index: Option<u32>

Pin the decoder to this physical GPU; None = first matching adapter.

filters: Arc<FilterChain>

Prepared per-frame video filter chain (crop/pad/flip/rotate/grayscale/ overlay/colour), applied after colorspace normalize and before the frame is fanned out to the per-rung scalers. Overlay images are loaded once at prepare time. Arc so the per-GPU pump configs clone it cheaply.

Trait Implementations

impl Clone for DecodePumpConfig

fn clone(&self) -> DecodePumpConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.
