This document is a list of reported errata issues for the current version of the text of the HEVC standard (Rec. ITU-T H.265 v4 of 12/2016 and ISO/IEC FDIS 23008-2:201x) for consideration and corrective action. Reference software problems are not included in this report. It is an inclusive collection, and may contain some items that do not apply to the final current published text of the parent bodies.

Published in meeting:

It has been reported that there is an error in the AVC text specification for the recently added levels 6, 6.1, and 6.2 (which were added to support very large picture sizes such as “8K” pictures). The problem is that the current specification requires the decoder to support a 17-bit range of motion vector deltas, which is suggested to be an oversight and is reportedly not supported in the JM reference software.
