– The LY reference index of the history-based motion vector predictor candidate HmvpCandList[i] is equal to refIdxLX
should change to
– The LY reference index refIdxLY of the history-based motion vector predictor candidate HmvpCandList[i] and refIdxLX should match the following conidtion :
DiffPicOrderCnt( refPicListY[ refIdxLY], RefPicListX[ refIdxLX ] ) = 0
[WJ: condition is wrong, it should be POC based, eg. DiffPicOrderCnt( refPicListY[ refIdxLY], RefPicListX[ refIdxLX ] ) is equal to 0
