4. WG status update
   * some documents expired:
   ** I-D was expired :draft-ietf-cellar-matroska-05.txt
   ** I-D was expired :draft-ietf-cellar-codec-04.txt
   ** I-D was expired :draft-ietf-cellar-tags-04.txt

   * FFV1 -- version 18 was posted 2020-10-07, waiting for revision

5. remaining FFV1 issues from DISCUSS
   * We talked about how to respond to DISCUSS ballots from area directors.
   Basically, we reply to their ballot e-mails and either point them to an
   update that should resolve their DISCUSSes and COMMENTS, or talk with them
   and resolve any confusion (on our part, or on theirs).

6. Matroska issues

Sampling accuracy:
Reuse TrackTimestampScale which was deprecated, but has running code to solve
the problem of time scaling.

<i didn't understand that second question>

Recurring Attribute of element:   what does it mean?
The answer is in the EBML document!

draft-ietf-cellar-tags-04.txt document is pretty much done, and won't change
very much. draft-ietf-cellar-codec-04.txt how deep do we want to describe codec
mappings?  We probably aren't going to do this for every codec, but maybe a few

8. FLAC issues

"ffv1" for audio.
(A bit related to ogg, when you mux it?)
We still want to do this at some point, but it is not a priority compared to
ffv1, (and ffv1-v4).


- From Spencer - when do we need to talk about 2021 meeting dates? :-)
- Answer - we'll put this on the December Agenda

Some revision to the WG milestones, to be confirmed with AD.

    NEXT MEETING December 1, 2020.
