- Nigel: Today we have WebVTT headers, IMSC 1.2 PR.
- 15:08:11 [nigel]
- .. We also have the ARIB liaison tickets to complete our iteration over, and TTML2 2nd Ed IR,
- 15:08:23 [nigel]
- .. but I note that we have no Editor of IMSC or TTML2 present.
- 15:08:30 [nigel]
- .. Any other business, or points to raise?
- 15:08:54 [nigel]
- Topic: Where should "headers" go relative to the `WEBVTT` magic string? webvtt#485
- 15:08:59 [nigel]
- github: https://github.com/w3c/webvtt/issues/485
- 15:09:12 [nigel]
- Gary: We discussed this last week. We put it back on this week because Roger Pantos,
- 15:09:27 [nigel]
- .. the main editor of HLS, replied saying that they should specify the header location in HLS.
- 15:09:51 [nigel]
- .. I kinda agree with him except that there are some feature requests for WebVTT for the
- 15:10:06 [nigel]
- .. future that might use headers. We don't want to be in a situation where there are
- 15:10:20 [nigel]
- .. incompatible header specifications in different specs. At the same time, until we add
- 15:10:30 [nigel]
- .. features that use headers I'm not sure that WebVTT should describe what headers are.
- 15:10:37 [nigel]

- 15:11:04 [nigel]
- Nigel: I agree with the concern that incompatible definitions would be a bad thing.
- 15:11:22 [nigel]
- .. Since WebVTT previously defined this, I think it would make sense at least for WebVTT
- 15:11:39 [nigel]
- .. to define header conceptually even if with a note saying it isn't directly used by WebVTT
- 15:11:53 [nigel]
- .. yet, but may be in the future, and is available as an extension point for other uses.
- 15:13:20 [nigel]
- Gary: Yes, actually having it as an extension/feature and calling it out as that makes sense.
- 15:13:25 [nigel]
- .. I hadn't thought of that as a possibility.
- 15:13:44 [nigel]
- .. Then HLS could potentially still specify it but also still point to WebVTT.
- 15:13:51 [nigel]
- .. We could also try going with the most minimal definition of header.
- 15:14:26 [nigel]
- .. As I said last time, it was removed because someone was asking for clarification of usage,
- 15:14:40 [nigel]
- .. and it was removed rather than trying to iron out the issues. We either need to iron
- 15:14:49 [nigel]
- .. out the issues or pare down the definition so it doesn't really matter.
- 15:14:56 [nigel]
- Nigel: Makes sense to me.
- 15:15:50 [nigel]
- Gary: I'll take a look at that as Editor.
- 15:16:43 [nigel]
- .. I'll try to reply to the HLS mailing list (I have to join it first!)
- 15:17:56 [nigel]
- SUMMARY: @gkatsev to draft pull request bringing pared-down header definition back into WebVTT.
- 15:18:24 [nigel]
- Topic: IMSC 1.2 PR Published
- 15:18:52 [nigel]
- Nigel: We published the PR on 16th June.
- 15:18:56 [nigel]
- -> https://www.w3.org/TR/2020/PR-ttml-imsc1.2-20200616/ IMSC 1.2 PR
- 15:19:17 [nigel]
- .. Need to make the group aware of some late changes.
- 15:19:32 [nigel]
- .. First the link to Liberation Mono fonts no longer worked so had to be changed.
- 15:20:02 [nigel]
- .. Second, the URLs to EBU specs seem to be wrong. There was an email thread with
- 15:20:19 [nigel]
- .. Frans from EBU who advised us. This change has not yet been made but I believe we can
- 15:20:34 [nigel]
- .. make it prior to Rec publication, since it is only URLs that are changing, not the referenced
- 15:20:38 [nigel]
- .. documents themselves.
- 15:20:55 [nigel]
- .. That's w3c/imsc#561.
- 15:21:13 [nigel]
- .. Also the BBC's AC rep, Chris Needham proposed some editorial changes to the Changes
- 15:21:25 [nigel]
- .. section to clarify them. They are in w3c/imsc#560.
- 15:21:45 [nigel]
- .. I am not expecting any process issue with those changes.
- 15:24:56 [nigel]
- Topic: CSS font-matching algorithm may introduce fingerprinting issues w3c/ttml2#1202 (PING review)
- 15:25:07 [nigel]
- github: https://github.com/w3c/ttml2/issues/1202
- 15:25:22 [nigel]
- Nigel: Just to note I did contact PING last week after the call and have not had a reply yet.
- 15:25:48 [nigel]
- .. Aside from that I'd note that we have no proposals on the table for resolving the impasse.
- 15:26:01 [nigel]
- .. The proposal from PING has objections from TTWG, and the proposal from TTWG that
- 15:26:11 [nigel]
- .. has consensus seems to have an objection from PING!
- 15:26:42 [nigel]
- .. I would really appreciate any other proposals if anyone can contribute them.
- 15:27:41 [nigel]
- SUMMARY: Awaiting PING response to the Chair, other proposals for resolving this issue are welcome.
