-> https://www.w3.org/calendar/tpac2026/grid/ Draft TPAC schedule

15:09:06 [cpn]

Nigel: There's a draft TPAC schedule. TTWG meets most of the day on the Thursday (29 Oct), after the MEIG + TTWG + APAWG joint meeting

15:09:31 [cpn]

... But that joint meeting is at the same time as AGWG, and ??. There might be an overlap of people

15:09:52 [cpn]

... Media WG meets on Friday, no overlap

15:10:31 [cpn]

... On Monday, MEIG is the first half, then there's a joint meeting after lunch. Audio WG meets all day Monday

15:11:00 [cpn]

... This means we meet Monday, then Thursday and Friday. If this doesn't work for anybody, this is the time to give feedback

15:11:24 [cpn]

Gary: I won't be there in person, which means I'll only be able to join remotely in the afternoon (in TPAC time)

15:12:00 [cpn]

Nigel: Andreas said he'd prefer to meet towards the end of the week, so it works out for him

15:12:20 [cpn]

Gary: Demuxed hasn't been announced yet, and there's a possibility it will overlap

15:12:29 [cpn]

Nigel: I'll ask Phil not to do that!

15:13:19 [cpn]

Nigel: I'm not hearing reasons to ask for changes

15:13:46 [cpn]

... I think they only want feedback if there are issues

15:13:47 [cpn]

Chris: Yes

15:13:54 [cpn]

Nigel: Anything else on TPAC?

Topic: WebVTT

15:16:43 [nigel]

Subtopic: Interop update

15:17:00 [cpn]

Gary: We met last week and we're going to try to meet about every other week

15:17:30 [cpn]

... In the last meeting, the WPT group want scoring criteria to be able to show whether we're making progress or not

15:17:47 [cpn]

... The current rendering tests should cover about 75% of the score, with the other API and parsing tests being the other 25%

15:18:07 [cpn]

... Rendering is the big interop issue, and that exercises the entire stack, which is helpful

15:18:48 [cpn]

... The other thing, is to have people looking at the tests to see if anything is wrong, in their own time. Instead we'll spend meeting time on that, which should work better

15:18:55 [nigel]

15:19:20 [cpn]

... Having people be able to discuss in a meeting is helpful

15:19:57 [cpn]

Nigel: It's interesting that some things are subjective, does that point to things that need to be defined objectively in the spec, or is that by design?

15:20:51 [cpn]

Gary: Sometimes it's unclear what the tests are trying to do, until you look into them a bit more

15:20:58 [cpn]

Nigel: So you don't envisage changes to the spec?

15:21:27 [cpn]

Gary: This interop work is identifying the tests that are definitely failing. Are the tests wrong, are the browsers rendering incorrectly, or is the spec incorrect and needs to be updated?

Nigel: Are there notes?

15:22:31 [cpn]

Gary: Not really, last time only a few of us joined, myself, Dana, and Romain

15:23:20 [cpn]

Nigel: How do people find out about the meetings?
