Fields

profile: u8

Stream profile, 0 for 8-10 bits/component 4:2:0 or monochrome; 1 for 8-10 bits/component 4:4:4; 2 for 4:2:2 at any bits/component, or 12 bits/component at any chroma subsampling.

max_width: c_int

Maximum dimensions for this stream. In non-scalable streams, these are often the actual dimensions of the stream, although that is not a normative requirement.

max_height: c_int

Maximum dimensions for this stream. In non-scalable streams, these are often the actual dimensions of the stream, although that is not a normative requirement.

layout: Dav1dPixelLayout

< format of the picture

pri: Dav1dColorPrimaries

< color primaries (av1)

trc: Dav1dTransferCharacteristics

< transfer characteristics (av1)

mtrx: Dav1dMatrixCoefficients

< matrix coefficients (av1)

chr: Dav1dChromaSamplePosition

< chroma sample position (av1)

hbd: u8

0, 1 and 2 mean 8, 10 or 12 bits/component, respectively. This is not exactly the same as ‘hbd’ from the spec; the spec’s hbd distinguishes between 8 (0) and 10-12 (1) bits/component, and another element (twelve_bit) to distinguish between 10 and 12 bits/component. To get the spec’s hbd, use !!our_hbd, and to get twelve_bit, use hbd == 2.

color_range: u8

Pixel data uses JPEG pixel range ([0,255] for 8bits) instead of MPEG pixel range ([16,235] for 8bits luma, [16,240] for 8bits chroma).
