NumEntryPoints in R0481

In NumEntryPoints derivation, "&& sps_wpp_entry_point_offsets_present_flag" was removed in R0481. But I thinks just replace "&& sps_wpp_entry_point_offsets_present_flag" with "&& sps_entropy_coding_sync_enabled_flag" should be right description in this case.

Another issue can be gating flag (in R0481 sps_entry_point_offsets_present_flag in SPS while in P2001 entry_point_offsets_present_flag in PPS) but this could be beyond my report.

Thanks! Pleas take a look at JVET-R2001-v1, and let me know if there is still anything that should be changed regarding this item.

Thanks, but it seems JVET-R2001-v1 has the same issue in R0481.

The point is that "ctbAddrY != prevCtbAddrY" should only apply to wavefront as follows.

NumEntryPoints = 0
if( sps_entry_point_offsets_present_flag )

( ctbAddrY != prevCtbAddrY && sps_entropy_coding_sync_enabled_flag ) )

Got you. You are right. Added " && sps_entropy_coding_sync_enabled_flag" in R2001-v2 that's being worked on. Thanks!
