TTML2

Publication of updated CR

Status update @himorin

WebVTT

WebVTT Status

Currently, still CR. Output on https://w3c.github.io/webvtt/ and https://www.w3.org/TR/webvtt/ is different. Outstanding PRs mark more things as at-risk. Some of these features should come back, potentially in an evergreen feature addition.

Outstanding PRs

VTTRegion lines long and region lines +/- MAX_VALUE

I think these two are good to go but worth raising to see if anyone wanted to take a look and raise issues.

new snapshot

This was approved and potentially can go into a new CR but requires a CfC before requesting a transition, it also includes the two changes above, and we may want to include the new feature request of unbounded endTime

unbounded endTime

Any objections? How do we resolve the IPR.

Next steps

Likely:

• update and merge bikeshed PR
• merge VTTRegion lines long
• merge region lines +/- MAX_VALUE
• merge unbounded endTime change
• update snapshot PR
• request CfC for a new webvtt CR
• remove at-risk items
• Start process to bring to Proposed Rec?
  Also:
• Figure out how to mark new features for a Rec.
• Consolidate snapshot and index.bs?

GitHub Pages after switching master to main branch names

A couple of repos had issues with their GitHub pages publication after the branch name switch - one fix was to change the publication directory, save, then change it back and save again.

Agenda+ AOB

[gkatsev]

AOB would be DST, I don't remember if we've solved it officially forever last time it was brought up.

[himorin]

(sub-)agenda+ for master to main

• it seems we need to update configurations on imsc-tests, imsc-vnext-reqs, png-hdr-pq, tt-module-karaoke, tt-reqs, and tt-module-live
