Description
After generating a multi-layer bitstream with VTM 11.0, an error is thrown at the decoder side.
ERROR: In function "checkRPL" in ~/VVCSoftware_VTM/source/Lib/CommonLib/Slice.cpp:718: Either of the following conditions shall apply for the picture referred to by each ILRP entry, when present, in RefPicList[ 0 ] or RefPicList[ 1 ] of a slice of the current picture:-The picture is a GDR picture with ph_recovery_poc_cnt equal to 0 or an IRAP picture.-The picture has TemporalId less than vps_max_tid_il_ref_pics_plus1[ currLayerIdx ][ refLayerIdx ], where currLayerIdx and refLayerIdx are equal to GeneralLayerIdx[ nuh_layer_id ] and GeneralLayerIdx[ refpicLayerId ], respectively.
The CHECK is throwing the error when either of the conditions in the description are met:
(cond1 && cond2) || cond3 || cond4
But the error should be thrown in the negative case:
(!cond1 || !cond2) && !cond3 && !cond4
