1300	Possibility of PredFlagL1 to be 1 in P Slice when subblokc-based temporal merging candidate is chosen	ksthey		"In 8.5.5.3:
The derivation process for collocated motion vectors as specified in subclause 8.5.2.12 is invoked with currCb, colCb, ( xColCb, yColCb ), refIdxL1 set equal to 0 and sbFlag set equal to 1 as inputs and the output being assigned to the motion vector of the subblock '''mvL1SbCol'''[ xSbIdx ][ ySbIdx ] and '''availableFlagL1SbCol'''.

In 8.5.5.4:
The derivation process for collocated motion vectors specified in subclause 8.5.2.12 is invoked with currCb, colCb, (xColCb, yColCb), refIdxL1 set equal to 0, and sbFlag set equal to 1 as inputs and the output being assigned to '''ctrMvL1''' and '''ctrPredFlagL1'''.

The abovementioned texts are invoked regardless of the slice type. 
As the result, it is possible to have '''predFlagL1'''[ xSbIdx ][ ySbIdx ] '''equals to 1''', even if current slice is a '''P slice''', when subblockMergeCandList[ merge_subblock_idx[ xCb ][ yCb ] ] is equal to SbCol in 8.5.5.2 ."	defect	closed	minor		spec		fixed		ksuehring bbross XiangLi fbossen jvet@…
