| Summary | 0000356: violated constraint in the section A.3.3 as specified in the point e) | ||||
| Description | Dear Karsten, Alexis, All, I'm thinking there is another 'similar' violation in the JM but this one probably looks like more easily to be cleanly fixed. Please take a look at statement in the section A.3.3 as specified in e): e) In bitstreams conforming to the Main, High, Progressive High, High 10, High 4:2:2, High 4:4:4 Predictive, or Extended profiles, the value of sub_mb_type[ mbPartIdx ] with mbPartIdx = 0..3 in B macroblocks with mb_type equal to B_8x8 shall not be equal to B_Bi_8x4, B_Bi_4x8, or B_Bi_4x4 for the levels in which MinLumaBiPredSize is shown as 8x8 in Table A-4 for the Main, High, Progressive High, High 10, High 4:2:2, High 4:4:4 Predictive profiles and in Table A-5 for the Extended profile. In my bitstreams, I’m certainly seeing ‘not to be used’ the B_Bi_8x4 and 4_8 subpartitions at the higher Levels >=3.1 per MinLumaBiPredSize = 8x8 After you’ll have a chance to confirm that the above check is not enforced in the JM19, I’ll report this into the BugTracker. Best regards, Andrew | ||||
