Milestone review:

Previous status: Jerome is now able to focus on FFV1-v4, since we've published FFV1. ACTION Spencer to send e-mail to DISPATCH when we submit a (small) update. We should wait until we have a bit more text, or bigger issues, to publish as a draft.
Are we ready to submit a working group draft for EBML updates (errata plus additions) yet? (https://github.com/ietf-wg-cellar/ebml-specification/tree/corrections-doc)
- we can still wait for more feedback/bigger changes before submitting anything - ETA is "after we get Matroska out, so we know everything Matroska needs will be covered"
- also have some implementation/experience reports.

FLAC as Standards Track or Informational

PR #135 is OK to push
Closed for now

errata to acknowledge the MP4 registry work for FFV1

as listed in https://mailarchive.ietf.org/arch/msg/cellar/kcchQqo6aq2veXijhwVmozQDLCc/.
Steve will enter errata for this
Need to add same material for FFV1-V4 but we do this in GitHub, because that's not a published RFC
https://github.com/FFmpeg/FFV1/blob…master/ffv1.md#matroska-file-format=
See https://mp4ra.org/#/codecs and search FFV1

?? email on #matroska-user with the subject "[Matroska-users] Video Coding History questions”

Postponed to April meeting

push matroska-09 and submit it for review to the higher powers

One remaining issue, and it's unrelated
Ready to push this one now.
We'll initiate WGLC and forward email to appropriate mailing lists outside IETF.
Will be four week WGLC with two-week reminder

publish codec-08 and tags-08 as well since they seem to expire in April

(but "Codec changes include proper reference to the (renamed) UncompressedFourCC element and AVS3 codec" and "Tags have the new TVDB2 tag")
will publish when they expire - they're not being WGLCed

FLAC issues - Discussion on the call

Two new issues, please review
Issues #145 and #146

Matroska issues - Discussion on the call

Can defer this and focus on codecs and tags until after WGLC

FFV1 v4 issues - Discussion on the call

No updates on this call
We need to discuss directions on the April call

AOB?
