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)

Agenda Items

New business: Email to mailing list, on ffv1/PNG as a format.

• "Proposal to embed FFV1 as a compression method into PNG or another
  format"

• FFV1 compression to be used within PNG container.

  • That would require a new PNG compression ID for FFV1.

• Who is responsible for the "IANA" considerations for getting a new
  compression ID for FFV1?

  • PNG WAS RFC 2083, but that's not authoritative. PNG went to W3C,
    but ISO/IEC JTC 1/SC 24 is now the owner.
  • will need liason help with this.
  • github: https://github.com/w3c/PNG-spec/issues
    https://www.w3.org/TR/png-3/

• This is interesting, but maybe not in scope for Cellar?

  • An excellent question to discuss with our new AD, Orie Steele
  • Is this our problem? Only because FFV1 is our problem, and we'd
    like for FFV1 to be everywhere.
  • Can the people who are interested in adding FFV1 to PNG make
    that happen without help from Cellar?

• Jérôme will follow up with bloodysword=40gmx.net@dmarc.ietf.org.

• if we need help, we can follow up with liaison-coordination@iab.org
  (if this needs to happen at ISO) or Martin Thomson at
  https://datatracker.ietf.org/person/Martin%20Thomson (as our W3C
  liaison manager)

AUTH48 status report on Matroska edits

I propose that we change section 20.3 as follows:

The menu features are handled like a chapter codec.
This is the subject of future work. [informative: chapter-codec]

Next steps for additional Matroska specifications

• which document to start on next?
• there is a google summer of code student working on interactive
  movie, and chapter codec will get many updates over the summer.
• cellar-codec now has a milestone associated with it now.

FLAC IESG ballot

• Document was approved for publication by IESG.
• No action required until this document appears in AUTH48

AOB?
