Description

MER check (highlighted int the bellow) is missing for availableA2 and availableB3.

  1. When sps_affine_enabled_flag is equal to 1, the following applies:

– The derivation process for neighbouring block availability as in clause 6.4.4 is invoked with the current luma location ( xCurr, yCurr ) set equal to ( xCb, yCb ), the neighbouring luma location ( xNbA2, yNbA2 ), checkPredModeY set equal to TRUE, and cIdx set equal to 0 as inputs, and the output is assigned to the block availability flag availableA2.
– When xCb >> Log2ParMrgLevel is equal to xNbA2 >> Log2ParMrgLevel and yCb >> Log2ParMrgLevel is equal to yNbA2 >> Log2ParMrgLevel, availableA2 is set equal to FALSE.
– The derivation process for neighbouring block availability as in clause 6.4.4 is invoked with the current luma location ( xCurr, yCurr ) set equal to ( xCb, yCb ), the neighbouring luma location ( xNbB3, xNbB3 ), checkPredModeY set equal to TRUE, and cIdx set equal to 0 as inputs, and the output is assigned to the block availability flag availableB3.
– When xCb >> Log2ParMrgLevel is equal to xNbB3 >> Log2ParMrgLevel and yCb >> Log2ParMrgLevel is equal to yNbB3 >> Log2ParMrgLevel, availableB3 is set equal to FALSE.
