Description

Please replace

yColCb = Clip3( yCtb,

Min( CurPicHeightInSamplesY − 1, yCtb + ( 1 << CtbLog2SizeY ) +3 ),

yColCtrCb + ( tempMv[1] >> 4 ) ) (8-164)

with

yColCb = Clip3( yCtb,

Min( CurPicHeightInSamplesY − 1, yCtb + ( 1 << CtbLog2SizeY ) -1 ),

yColCtrCb + ( tempMv[1] >> 4 ) )

to match the VTM3.0 reference code.

The temporal motion vectors should not go beyond the current CTU row.
