Milestone review:

any changes to: https://datatracker.ietf.org/wg/cellar/about/

Jul 2022 Submit specification for FFV1 video codec version 4 to IESG
(Standards Track)

DISCUSSION 1: proposal is to remove this milestone.
agreed!

DISCUSSION 2: of codecs, tags, chapter-codecs and control...
a) which one(s) is next?
b) are we still committed to doing them all?

• codecs and tags are really important
• chapter-codecs is being worked on, have a Google Summer of Code
  student working on code.
  ** ECMAScript inside Matroska.
• control tracks might never get published? (Removed from Matroska).
  Might never use these features.

• matroska-v5, could start working on. Start at end of summer! This
  will be an extension document, not a -bis document.

• tags is probably the fastest, so work on it next.

• codecs will take more time, but is probably more relevant to people

AUTH48 status report

recap of IANA issues with Matroska document.

• are we done yet?
• Steve thinks he has agreed to all the Matroska proposed changes from
  the RFC Editor - it's good to reply to email and make sure they know
  we agree.
• We're just making sure the requirements in the document matches what
  will appear in the IANA registry.

FLAC IESG ballot

• still in RFC-editor queue.

FFv1 in PNG wrapper question

• Michael and Spencer talked to our new AD about this
• The work needs to be done in W3C, not in the IETF - they are
  responsible for PNG
• Our new AD, Orie, has experience as a W3C document editor
• We need a champion, who can take this forward
• We need at least one W3C member who can help with this - perhaps
  Library of Congress?

AOB?

• no other business.

Next meeting is 2024-08-27. (end of summer)
