| Summary | 0000077: Incorrect Stats: Stuffing Bits (no impact on compressed bitstream) | ||||
| Description | The encoder reports wrong amount Stuffing Bits in stats.dat when using CABAC. stats->bit_use_stuffingBits accumulates Stuffing Bits from RD optimization | ||||
| Additional Information | The following patch should fix the problem: Index: lencod/inc/global.h =================================================================== 155a156 > BITS_STUFFING, Index: lencod/src/macroblock.c =================================================================== 223a224 > stats->bit_use_stuffingBits[img->type] += bitCount[BITS_STUFFING]; Index: lencod/src/biariencode.c =================================================================== 194a195 > int* bitCount = img->mb_data[img->current_mb_nr].bitcounter; 200c201 < stats->bit_use_stuffingBits[img->type]+=(5-remaining_bits); --- > bitCount[BITS_STUFFING]+=(5-remaining_bits); 210c211 < stats->bit_use_stuffingBits[img->type]+=(13-remaining_bits); --- > bitCount[BITS_STUFFING]+=(13-remaining_bits); 230c231 < stats->bit_use_stuffingBits[img->type]+=(21-remaining_bits); --- > bitCount[BITS_STUFFING]+=(21-remaining_bits); | ||||

Forgot some lines which also need to be added. Index: lencod/src/macroblock.c =================================================================== 657a659 > currMB->bitcounter[BITS_STUFFING ] = 0; Index: lencod/src/slice.c =================================================================== 155a156 > int tmp_stuffingbits=img->mb_data[img->current_mb_nr].bitcounter[BITS_STUFFING];; 201a203,204 > stats->bit_use_stuffingBits[img->type] += img->mb_data[img->current_mb_nr].bitcounter[BITS_STUFFING] - tmp_stuffingbits; > |

I have merged the fix into my development tree. |
