Description

The text provided with document JVET-M0908 adds the following steps 2 and 3 in section 8.6.2.5:

– If the sample p0 or q0 is in the coding block of a coding unit coded with intra prediction mode, bS[ xDi ][ yDj ] is set equal to 2.
– Otherwise, if the block edge is also a transform block edge and the sample p0 or q0 has ciip_flag equal to 1, bS[ xDi ][ yDj ] is set equal to 2.
– Otherwise, if the sample p0 or q0 has ciip_flag equal to 1, bS[ xDi ][ yDj ] is set equal to 1.
– Otherwise, if the block edge is also a transform block edge and the sample p0 or q0 is in a transform block which contains one or more non-zero transform coefficient levels, bS[ xDi ][ yDj ] is set equal to 1.

In the software provided in https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM/merge_requests/215/diffs
the order of steps 3 and 4 is reversed, which may lead to different results when combined with the changes from M0471
