Description

Range of cpIdx in the output of process 8.5.5.8 should be modified from numCpMv - 1 to 2. Because in step 7 of 8.5.5.7, cpIdx from 2 to 0 is used.

In 8.5.5.8, change from:
Output of this process are:
– the constructed affine control point motion vector prediction candidiates cpMvLX[ cpIdx ] with cpIdx = 0..numCpMv − 1 and X being 0 or 1.

To:
– the constructed affine control point motion vector prediction candidiates cpMvLX[ cpIdx ] with cpIdx = 0..2 and X being 0 or 1.

In 8.5.5.7, change from:

  1. When numCpMvpCandLX is less than 2, the following applies

– The derivation process for constructed affine control point motion vector prediction candidate as specified in clause 8.5.5.8 is invoked with the luma coding block location ( xCb, yCb ), the luma coding block width cbWidth, the luma coding block height cbHeight, and the reference index of the current coding unit refIdxLX as inputs, and the availability flag availableConsFlagLX, the availability flags availableFlagLX[ cpIdx ] and cpMvpLX[ cpIdx ] with cpIdx = 0..numCpMv − 1 as outputs.

To:

  1. When numCpMvpCandLX is less than 2, the following applies
