15:03:23 [nigel]
.. IMSC-HRM
15:03:27 [nigel]
.. DAPT
15:03:40 [nigel]

15:03:51 [nigel]
no other business
15:03:56 [nigel]
Topic: TPAC Planning
15:04:12 [nigel]
Nigel: This is our last call before we meet at TPAC
15:04:45 [nigel]
.. Would be good to have as many agenda topics as needed for Chairs to wrangle.
15:05:14 [nigel]
Agenda: https://github.com/w3c/ttwg/issues/261
15:05:33 [nigel]
Github: https://github.com/w3c/ttwg/issues/262
15:06:16 [nigel]
Nigel: Specific requested topics:
15:06:34 [nigel]
.. To discuss webvtt issue 511 about metadata cue formats
15:06:36 [nigel]
.. and
15:07:00 [nigel]
.. Eric Carlson and Marcos Caceres asked for time to talk about a Text Track Cue proposal they are planning to work on.
15:07:36 [nigel]
Present+ Atsushi

15:07:55 [nigel]
.. That one is about cues that insert HTML fragments. I think Pierre had some involvement with that
15:08:01 [nigel]
.. several years ago.
15:08:10 [nigel]
.. It's in the Safari Developer Preview and has been for a while.
15:08:28 [nigel]
.. Looks like they want to take it to the next stage and discuss actual spec changes, and TTWG
15:08:33 [nigel]
.. is one of the affected groups I think.
15:08:54 [nigel]
.. They asked for it to be later in the day so US folk can dial in. Eric will be there in person.
15:08:57 [nigel]
Gary: I will not be.
15:09:20 [nigel]
Nigel: Are there any other specific agenda topic requests right now?
15:10:25 [nigel]
.. The other two agenda topics that I recalled DAPT and IMSC-HRM implementations
15:10:42 [nigel]
.. As last year for DAPT I would hope to make some progress if Cyril is present.
15:11:00 [nigel]
Cyril: I will not be there in person but can wake up early to join discussions.
15:11:40 [nigel]
.. The Media WG meets from 1400-1900 (on whichever day of the week) to accommodate people on the West Coast.
15:12:01 [nigel]
Gary: I just checked - they meet on Monday afternoon, and MEIG meets on Monday morning.
15:12:48 [nigel]
Nigel: I don't think I've received feedback on DAPT or IMSC-HRM yet
15:13:00 [nigel]
Pierre: I've had some interest from folks who want me to bug them in September.
15:13:13 [nigel]
.. One major platform ran imschrm on a big part of their library.
15:13:22 [nigel]
.. It turns out that a bunch of their IMSC documents were actually invalid.
15:13:36 [nigel]
.. We're in the process of making sure that all the failures were not due to HRM failures.
15:13:50 [nigel]
Cyril: Syntactically?
15:14:06 [nigel]
Pierre: Yes, they were invalid syntactically - all the failures were not HRM related.
15:14:39 [nigel]
Nigel: Were they the sort of syntax errors you might expect to be valid reasonably?
15:15:12 [nigel]
Pierre: One of the issues was that 29.97 framerate content had frame counts of 30 occasionally.
15:15:16 [nigel]
.. We're working through that.
15:15:22 [nigel]
.. I expect mid-late September to have additional results.
15:15:45 [nigel]
Nigel: Does that mean we have no IMSC or IMSC-HRM topics for TPAC?
15:15:50 [nigel]
Pierre: I'm not aware of anything.
15:16:43 [nigel]
Andreas: One more possible topic. Currently some standards orgs are working on liaisons that may
15:16:55 [nigel]
.. reach TTWG and cause an agenda topic. We can decide when it arrives.
15:17:01 [nigel]
Nigel: Thank you for the warning.
15:17:14 [nigel]
.. In that case we have a small number of topics for the Chairs to arrange into a schedule.
15:17:16 [nigel]
.. Thanks all.
15:17:25 [nigel]
.. Anything else on TPAC planning?
15:18:20 [nigel]
Subtopic: Joint meetings
15:19:05 [irc]
irc has joined #tt
15:19:19 [nigel]
Nigel: On the Monday 11:50-12:35 Spanish time, joint between TTWG, MEIG and (I thought) Media WG.
15:19:32 [cpn]
cpn has joined #tt
15:19:56 [nigel]
.. Chris has put together an agenda for the whole MEIG session, still a little fluid in terms of the details on the slides.
15:20:08 [nigel]
-> https://docs.google.com/presentation/d/1sadWsW1NZkfjlUdZ5FkXa_taUCzp1jyBNtemqY2WXgE/edit?usp=sharing MEIG agenda slides
15:20:55 [nigel]
Gary: We had previously brought up a discussion about the Text Track API but
15:21:02 [nigel]
.. I don't think anyone is ready to talk about that because I think,
15:21:11 [nigel]
.. especially because of my circumstances, it fell on the floor.
15:21:45 [nigel]
Nigel: Yes, that is a shame, however the Text Track Cue API discussion might help that along potentially.
15:21:59 [nigel]
Gary: Yes, that definitely covers a portion of our big ideals.
15:22:22 [nigel]
Nigel: Let us know if there's anything else to discuss in that joint meeting.
15:22:49 [nigel]
.. The next joint call we have is on the Thursday afternoon, with APA and MEIG, 14:30-16:30 Spanish time.
15:23:22 [nigel]
.. Chris previously put together a short agenda of bullet points which I think we've circulated here before.
15:23:29 [nigel]
.. I don't have it to hand right now.
15:23:58 [nigel]
.. I propose we re-circulate that offline.
15:25:22 [nigel]
.. I think we normally put together an agenda page that's more easily consumable in one place by attendees
15:25:28 [nigel]
.. so I should give myself the action to do that.
15:26:17 [nigel]
-> https://github.com/w3c/ttwg/issues/265 Prepare agenda page for TPAC
15:26:34 [nigel]
Topic: IMSC-HRM
15:26:51 [nigel]
Nigel: Pierre, you mentioned this at the front of the meeting. Anything more to say?
15:27:03 [nigel]
Pierre: No, based on encouraging commitments I expect results at the end of September.
15:27:07 [nigel]
Nigel: Great, thank you.
15:27:25 [nigel]
Pierre: Unless we discover that everyone has invalid IMSC libraries! That would be a bigger issue.
15:27:41 [nigel]
.. It is an issue because it makes testing the HRM difficult.
15:29:05 [nigel]
Nigel: There's a wider point here about the technical quality of tools.
15:29:11 [nigel]
.. I often see issues that need ironing out.
15:29:25 [nigel]
Pierre: Maybe there's an opportunity to make further progress on fixing invalid file production.
15:29:39 [nigel]
[Pierre drops off the call]
15:29:51 [nigel]
Topic: DAPT
15:30:19 [nigel]
Nigel: I haven't seen anything over the last few weeks. Cyril, have you?
15:30:33 [nigel]
Cyril: No, I stopped on this after the HR forms. I need to pick it up again.
15:30:47 [nigel]
.. You had some suggestions about the explainer, Nigel, which I need to action.
15:31:40 [nigel]
.. Maybe I could do the internationalisation request pointing to the draft explainer and then fix it?
15:31:53 [nigel]
Nigel: I don't think the changes I suggested were huge.
15:32:08 [nigel]
Cyril: In that case I can do them today or tomorrow and then make the request.
15:32:28 [nigel]
.. Also I sent messages to studio contacts to see if they have any opinions and can contribute comments.
15:32:35 [nigel]
.. I don't know if it will lead to anything.
15:32:48 [nigel]
.. I reached out to Disney, Warner, Apple, CableLabs and I think one more.
15:33:05 [nigel]
Nigel: Would you be able to add those to the Outreach log on the wiki page?
15:33:08 [nigel]
Cyril: Yes, I will.
15:33:30 [nigel]
Nigel: I also got around to contacting MESA today - thank you to both Matt and Pierre for providing details.
15:33:55 [nigel]
.. I added that to the Outreach log also.
15:34:31 [nigel]
.. We have a bunch of open pull requests that need some work too, most are for you Cyril, at least one is for me.
15:34:58 [nigel]
.. For the time being though I haven't received any responses to our liaisons other than acknowledgement, as far as I am aware.
15:35:14 [nigel]
.. We asked for responses by 10th September.
15:35:19 [cpn]
cpn has joined #tt
15:35:35 [nigel]
Cyril: You will not get a response from MPEG - I can tell you the request was received and reviewed,
15:35:38 [nigel]
.. and no action taken.
15:35:51 [nigel]
Nigel: That's fine, we've done what we needed.
15:37:03 [nigel]
.. I think I am expecting a response from ITU though, need to check.
15:37:17 [nigel]
.. I know they received the message and I think they discussed it.
15:37:44 [nigel]
.. Anything else to discuss re DAPT right now?
15:37:50 [nigel]
Cyril: I can't think of anything at the moment.
15:38:34 [nigel]
Topic: Meeting close
15:38:41 [nigel]
Nigel: We've completed our agenda, thank you everyone.
15:38:50 [nigel]
.. Next meeting will be in Seville, see you there, in person or remotely.
