1371	Incorrect subpicture boundaries	bheng		"
In equation 113, I believe SubpicRightBoundaryPos and SubpicBotBoundaryPos should be derived using the actual picture size from the PPS, not the maximum picture size from the SPS:

   SubpicRightBoundaryPos = Min( sps_pic_width_max_in_luma_samples - 1, ... )

   SubpicBotBoundaryPos = Min( sps_pic_height_max_in_luma_samples - 1, ... )			

These boundaries are used in several TMVP equations, such as the following:

   rightBoundaryPos = sps_subpic_treated_as_pic_flag[ CurrSubpicIdx ] ? SubpicRightBoundaryPos : pps_pic_width_in_luma_samples - 1	(585)			

When not present, the value of sps_subpic_treated_as_pic_flag[ i ] is inferred to be equal to 1.  So, the subpicture boundaries need to be derived correctly above, even if subpictures are not used. "	defect	closed	minor		spec	VVC D10 vG	fixed		ksuehring bbross XiangLi fbossen jvet@…
