1223	No CABAC contexts reset in WPP when slice segments starts on a new row	gregory		"In WPP mode for CTB at the start of a row CABAC contexts should be loaded from top-right CTB or reset in case top-right CTB is not available (e.g. in a different slice). In case of dependent slice segments reset is done only when top-right CTB is outside of the frame.

I attached a 1-frame stream which reproduces this problem and a patch which fixes it for decoder.

Looking at the source code I think the same problem exists in encoder."	defect	closed	major		HM	HM-12.1	invalid		fbossen ksuehring davidf jct-vc@…
