#33 | fixed | typo in DV derivation process | tech | lizhang |
Description |
In subcluase H.8.5.4,the following equation: MvDisp[ x ][ y ] = ivpMvFlagLX (H-236) shall be replaced by: MvDisp[ x ][ y ] = mvDisp (H-236) |

#41 | fixed | problem in cross-references | tech | lizhang |
Description |
The sub-clause H.8.5.2.2.5 (i.e., Illumination compensated sample prediction process) is never invoked. |

#112 | fixed | output_layer_flag conformance restriction in MV-HEVC encoding | tech | Tomohiro Ikai |
Description |
In Multiview Main profile, there is the following conformance restiction. "– When NumLayersInIdList[ OlsIdxToLsIdx[ olsIdx ] ] is equal to 2, output_layer_flag[ olsIdx ][ j ] derived according to any active VPS shall be equal to 1 for j in the range of 0 to 1, inclusive, for subBitstream." In HTM encoding with the current cfg files, the restriction fails: Solving this issue, we should remove the following two lines in cfg/MV-HEVC/baseCfg_2view.cfg OutputLayerSetIdx : 1 # Indices of layer sets used to derive additional output layer sets LayerIdsInAddOutputLayerSet_0 : 1 # Indices in VPS of output layers in additional output layer set 0 And we should replace the following lines in cfg/MV-HEVC/baseCfg_3view.cfg OutputLayerSetIdx : 1 2 # Indices of layer sets used to derive additional output layer sets LayerIdsInAddOutputLayerSet_0 : 1 # Indices in VPS of output layers in additional output layer set 0 LayerIdsInAddOutputLayerSet_1 : 2 # Indices in VPS of output layers in additional output layer set 1 with OutputLayerSetIdx : 2 # Indices of layer sets used to derive additional output layer sets LayerIdsInAddOutputLayerSet_1 : 2 # Indices in VPS of output layers in additional output layer set 1 Note: For 2 view case, I've conducted simulation with cfg change and confirmed the result but for 3 view case, I haven't conducted the simulation. In addition, we may have the checks in decoder/encoder. Decoder sides's check code may be as follows: Void TDecCavlc::parseVPSExtension( TComVPS* pcVPS ) {
#if NH_MV_FIX_TICKET_XXX
assert(pcVPS->getOutputLayerFlag(i, j));
#endif
