#8 | fixed | Bug in All Intra configuration with inter-layer prediction disabled | Vadim | bugdayci |
Description |
Encoder crashes in all intra configuration due to wrong slice type while encoding enhancement layers when inter-layer prediction is disabled. SHM2.0 was able to code all intra but the problem occurs in SHM3.0.1 and SHM4.0. Below piece of code in initEncSlice function, TEncSlice.cpp line 431, sets the slice type of enhancement layers to B_SLICE. #if SVC_EXTENSION
#endif In SHM2.0, some later process was correcting the slice type, however in the later versions of the software, slice type is not set correctly. The issue is resolved by changing the code as:
But I am not sure whether it should be corrected at this stage or at a later process as in SHM2.0. |

#9 | fixed | On editorial fixes on Profile, tier and level semantics in subclause F.7.4.4 | jlchen | tsukuba.takeshi |
Description |
Regarding Profile, tier and level semantics in subclause F.7.4.4, there exist several editorial bugs as follows: 1) Expression of inferring rule for profile_tier_level() syntax structure in VPS extension is incorrect. 2) syntax name "profile_layer_set_ref_minus1" should be "profile_ref_minus1". 3) Variable "lsIdx" should not be used for referring elements of "profile_ref_minus1[]". For more details, please see the attached modified WD. |

#10 | fixed | Derivation F-2 and F-3 | jlchen | eeehey |
Description |
The derivation of VpsInterLayerSamplePredictionEnabled and VpsInterLayerMotionPredictionEnabled is not right in the text. VpsInterLayerSamplePredictionEnabled[ i ][ j ] = direct_dependency_type[ i ][ j ] & 0x1 (F 2) VpsInterLayerMotionPredictionEnabled[ i ][ j ] = direct_dependency_type[ i ][ j ] & 0x2 (F 3) VpsInterLayerSamplePredictionEnabled and VpsInterLayerMotionPredictionEnabled shall also be true when direct_dependency_type[ i ][ j ] is equal to 0. |
