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
