JVET-AP1016 AVC with extensions and corrections (Draft 6) [K. Sühring, J. Boyce, G. J. Sullivan, Y.-K. Wang] (2026-04-30)

Primary editor: K. Sühring.

This was submitted to ITU consent on H.264 16th ed. It is noted that this may not be identical with the final version published by ITU-T.

Changes relative to JVET-AO1016 are as follows:

It is noted that the list above may not be complete; if some adoption is missing that is recorded somewhere else in the meeting notes it shall also be considered included.

Remains valid – not updated: JVET-AO1017 Support for additional SEI messages in AVC (Draft 5) [K. Sühring, J. Boyce, G. J. Sullivan, Y.-K. Wang] (2026-02-27)

Primary editor: K. Sühring

This was integrated into the text of the 12th edition of AVC, ISO/IEC FDIS 14496-10 (also including the changes mentioned under JVET-AP1016) which was submitted for ballot as WG 5 N 398 (with editing period of 2026-06-26). DoC WG 5 N 397 on the DAM was reviewed (identifying no need for changes relative to the preliminary version N 384, and approved on Friday 1 May at 1155-1200.

Remains valid – not updated: JVET-AN1018 HEVC with extensions and corrections (Draft 3) [Y.-K. Wang, B. Bross, S. Deshpande, G. J. Sullivan, A. Tourapis] (2025-10-17)

Primary editor: Y.-K. Wang.

This had been submitted to ITU consent on H.265 11th ed. It is noted that this may not be identical with the final version published by ITU-T.

Remains valid – not updated: JVET-AN1019 VSEI with extensions and corrections (Draft 1) [J. Boyce, J. Chen, S. Deshpande, M. M. Hannuksela, S. McCarthy, G. J. Sullivan, H. Tan, Y.-K. Wang] (2025-10-17)

Primary editor: J. Boyce.

This was submitted to ITU consent on H.274 4th ed. It is noted that this may not be identical with the final version published by ITU-T.

No output: JVET-Axx1020 through JVET-Axx1099
Remains valid – not updated JVET-AA1100 Common Test Conditions for HM Video Coding Experiments [K. Sühring, K. Sharman]

This specifies only the CTC for non-4:2:0 colour formats. The corresponding document for VVC is JVET-T2013, with no unification yet. See note under JCTVC-P1006 above.

Links to test sequences need to be updated due to the change of the content server.

Remains valid – not updated: JVET-AN2001 VVC with extensions and corrections (Draft 1) [Y.-K. Wang, B. Bross, M. M. Hannuksela, G. J. Sullivan] (2025-10-17)

Primary editor: Y.-K. Wang.

This was submitted to ITU consent on H.266 4th ed. It is noted that this may not be identical with the final version published by ITU-T

Remains valid – not updated: JVET-AO2002 Algorithm description for Versatile Video Coding and Test Model 23 (VTM 23) [Y. Ye, A. Browne, S. Kim]

Primary editor: Y. Ye.

New elements from notes elsewhere in this report (kept for future use):

It is noted that the list above may not be complete; if some adoption is missing that is recorded somewhere else in the meeting notes it shall also be considered included.

Remains valid – not updated: JVET-AJ2003 Guidelines for VTM-based software development [F. Bossen, X. Li, K. Sühring]
Remains valid – not updated: JVET-T2004 Algorithm descriptions of projection format conversion and video quality metrics in 360Lib (Version 12) [Y. Ye, J. Boyce]
Remains valid – not updated: JVET-AM2005 Additions and corrections for VVC version 4 (Draft 13) [G. J. Sullivan, B. Bross, M. M. Hannuksela, Y.-K. Wang] (2025-08-01)

Primary editor: G. J. Sullivan.

Remains valid – not updated: JVET-AM2006 Additional SEI messages for VSEI version 4 (Draft 7) [J. Boyce, J. Chen, S. Deshpande, M. M. Hannuksela, S. McCarthy, G. J. Sullivan, H. Tan, Y.-K. Wang] (2025-08-01)

Primary editor: J. Boyce.

Remains valid – not updated: JVET-AJ2007 Guidelines for NNVC software development [F. Galpin, S. Eadie, L. Wang, Z. Xie, Y. Li]

This might benefit from an update in the future, regarding some details of SADL implementation.

Remains valid – not updated: JVET-AN2008 Conformance testing for versatile video coding (Draft 8) [I. Moccagatta, F. Bossen, S. Iwamura, P. de Lagrange]

Primary editor: I. Moccagatta

Remains valid – not updated: JVET-AJ2009 Reference software for versatile video coding 2nd edition (Draft 2) [F. Bossen, K. Sühring, X. Li] [WG 5 DIS N 322)]

Software relating to H.266.2 and ISO/IEC 23090-16 can be found at https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_VTM/-/tree/2nd-edition.

Primary editor: F. Bossen.

[kept for future meetings] A request for next edition(s) of reference software(s) could be issued in the next meeting, and also CD(s) could be produced by the same meeting, as SC 29 is meeting beginning of February and could approve such projects without issuing a ballot. Issuing CD(s) by the January meeting (if mature enough) could avoid that an ISO version would lag behind an ITU version which might be submitted for consent in July 2026. Another consideration could be to start the process for ISO early enough in 2026, such that FDIS and ITU consent could be synchronized in April 2027.

JVET-AP1016 AVC with extensions and corrections (Draft 6) [K. Sühring, J. Boyce, G. J. Sullivan, Y.-K. Wang] (2026-04-30)

This was submitted to ITU consent on H.264 16th ed. It is noted that this may not be identical with the final version published by ITU-T.

Changes relative to JVET-AO1016 are as follows:

Errata / minor corrections related to interface text based on elements from JVET-AP0058, JVET-AP0091, JVET-AP0217

It is noted that the list above may not be complete; if some adoption is missing that is recorded somewhere else in the meeting notes it shall also be considered included.
