Enum ChromaReconstruction 

pub enum ChromaReconstruction {
    Bilinear,
    LumaGuided,
}

How a renderer reconstructs full-resolution chroma from a 4:2:0 buffer’s half-resolution plane.

The producer’s hint, not the format’s: an Nv12 buffer is chroma-subsampled either way, and this says what to do about it. Bilinear is the honest default — it is what the format carries, and it keeps a wrong stride or plane size visible rather than plausible. LumaGuided weights the chroma taps by the full-resolution luma, so colour follows the luma edges instead of being low-passed across them. A renderer may ignore it.

Variants

Bilinear

Sample the chroma plane bilinearly, as the format carries it.

LumaGuided

Reconstruct chroma with the full-resolution luma as a guide.
