### Milestone review:   {#milestone-review}

any changes to: https://datatracker.ietf.org/wg/cellar/about/  
<del>Jul 2022</del> Submit specification for FFV1 video codec version 4
to IESG (Standards Track)

## Agenda Items   {#agenda-items}

### New business: Email to mailing list, on ffv1/PNG as a format.   {#new-business-email-to-mailing-list-on-ffv1png-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   {#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   {#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][2]   {#flac-iesg-ballot}

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

## AOB?   {#aob}

    * The »No Time to Wait« conference is back for its eighth edition, taking place from September 11 to 13, 2024 at the ZKM | Center for Art and Media Karlsruhe.

Next meeting is 2024-06-25.
