◆ dct_tokens

int16_t* Vp3DecodeContext::dct_tokens[3][64]

This is a list of all tokens in bitstream order.

Reordering takes place by pulling from each level during IDCT. As a consequence, IDCT must be in Hilbert order, making the minimum slice height 64 for 4:2:0 and 32 otherwise. The 32 different tokens with up to 12 bits of extradata are collapsed into 3 types, packed as follows: (from the low to high bits)

2 bits: type (0,1,2) 0: EOB run, 14 bits for run length (12 needed) 1: zero run, 7 bits for run length 7 bits for the next coefficient (3 needed) 2: coefficient, 14 bits (11 needed)

Coefficients are signed, so are packed in the highest bits for automatic sign extension.
