}

The CMP1 codec header of a CR3 raw track.

Fields

version: u16

0x100 (lossless RAW and C-RAW with per-line quantisation) or 0x200 (C-RAW with quantisation maps).

width: u32

Full sensor buffer size (all planes interleaved).

height: u32

tile_width: u32

tile_height: u32

bits: u8

planes: u8

4 (Bayer planes) or 1 (8-bit single plane).

cfa_layout: u8

Position of the four planes in the 2x2 CFA cell (0 = RGGB, 1 = GRBG, 2 = GBRG, 3 = BGGR).

enc_type: u8

0 = planes are CFA colours, 1 = signed samples, 3 = decorrelated colour planes.

levels: u8

Wavelet levels (0 = lossless).

mdat_header_size: u32

Size of the per-sample header in the media data.

median_bits: u8

Output precision of encoding type 3.
