| DECLARE_ALIGNED (8, uint8_t, non_zero_count_cache)[15 *8] | |
| non zero coeff count cache. More... | |
| DECLARE_ALIGNED (16, int16_t, mv_cache)[2][5 *8][2] | |

| DECLARE_ALIGNED (16, uint8_t, mvd_cache)[2][5 *8][2] | |
| DECLARE_ALIGNED (8, uint16_t, sub_mb_type)[4] | |
| as a DCT coefficient is int32_t in high depth, we need to reserve twice the space. | |
| DECLARE_ALIGNED (16, int16_t, mb)[16 *48 *2] | |
| DECLARE_ALIGNED (16, int16_t, mb_luma_dc)[3][16 *2] | |
| as mb is addressed by scantable[i] and scantable is uint8_t we can either check that i is not too large or ensure that there is some unused stuff after mb | |
