Opened 10 years ago Closed 10 years ago #1294 closed defect (fixed)444, derivation of scanIdx and predModeIntra, mismatch between specification and software
Description
In section 7.4.9.11, "Residual coding semantics" in derivation of scanIdx the following condition:  If CuPredMode[ x0 ][ y0 ] is equal to MODE_INTRA and one or more of the following conditions are true:  log2TrafoSize is equal to 2.  log2TrafoSize is equal to 3 and cIdx is equal to 0.
differs from the one in reference software HM14.0+RExt7.2, when chromaArrayType is 3, log2TrafoSize is 3, and cIdx is different from 0. Condition in specification gives false, while condition in software gives true.  If CuPredMode[ x0 ][ y0 ] is equal to MODE_INTRA and one or more of the following conditions are true:  log2TrafoSize is equal to 2.  log2TrafoSize is equal to 3 and cIdx is equal to 0.  log2TrafoSize is equal to 3 and chromaArrayType is equal to 3.
