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?

  • 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?
