Robert Sparks has joined the WG as an incoming co-chair.
(not actually in the errata system)
application/x-font-otf (#921) which should probably be added to
Matroska v5 instead, but it’s just describing legacy Media Types
that should not be used
Action Spencer to fill out the registration form and begin the
process
We still need to do some analysis on what's actually needed in PR 946
(https://github.com/ietf-wg-cellar/matroska-specification/pull/946)
PR 932 isn't controversial, we can just merge this now
What document to work on next?
What are low-hanging fruit that can advance quickly?
need to add tag for latest EBU recommendations, but we don't have all
the information we need to describe the tag yet
https://tech.ebu.ch/publications/r128/
Jerome will check with the right person (bb010g on GitHub regarding
https://github.com/ietf-wg-cellar/matroska-specification/pull/865)
Action Spencer can start heading toward Working Group Last Call for
tags-15
*** codec-14 has some pull requests
PR 937 - SMPTE12 time code bit order needs to be clarified
PR 745 - needs a rebase and edit
PR 446 needs to be rebased
These aren't controversial, just need some attention
Have not done much work on this recently (focus has been on first two
Mastroska extension documents)
We do have a reference to a specification that is not public (DVD1 will
always be private)
Action Spencer to chase this reference so we can do the right thing
(we might have a solution as of the end of January 2025!)

https://www.dvdfllc.co.jp/notice.html "DVD Format Books (DVD
Specifications) will be deposited to the National Diet Library (NDL),
Japan (https://www.ndl.go.jp/en/index.html) as technology assets, early
2025."
This was taken out of the main Matroska specification because we thought
it was underspecified.
We may want to drop this document in the future. The document is not a
priority right now - no one is using it.
Next meeting is 2025-02-25.
