15:00:18 RRSAgent has joined #tt 15:00:22 logging to https://www.w3.org/2023/08/31-tt-irc 15:00:22 RRSAgent, make logs Public 15:00:23 Meeting: Timed Text Working Group Teleconference 15:00:32 MattS has joined #tt 15:01:24 Present: Andreas, Nigel, Gary, Matt, Pierre, Chris 15:01:27 Regrets: none 15:01:37 Agenda: https://github.com/w3c/ttwg/issues/257 15:02:06 Previous meeting: https://www.w3.org/2023/08/03-tt-minutes.html 15:02:18 Present+ Cyril 15:02:42 Topic: This meeting 15:02:47 scribe: nigel 15:03:19 Nigel: TPAC planning 15:03:23 .. IMSC-HRM 15:03:27 .. DAPT 15:03:40 .. Is any other business, or points to make sure we cover? 15:03:51 no other business 15:03:56 Topic: TPAC Planning 15:04:12 Nigel: This is our last call before we meet at TPAC 15:04:45 .. Would be good to have as many agenda topics as needed for Chairs to wrangle. 15:05:14 Agenda: https://github.com/w3c/ttwg/issues/261 15:05:33 Github: https://github.com/w3c/ttwg/issues/262 15:06:16 Nigel: Specific requested topics: 15:06:34 .. To discuss webvtt issue 511 about metadata cue formats 15:06:36 .. and 15:07:00 .. 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 Present+ Atsushi 15:07:39 pal has joined #tt 15:07:55 .. That one is about cues that insert HTML fragments. I think Pierre had some involvement with that 15:08:01 .. several years ago. 15:08:10 .. It's in the Safari Developer Preview and has been for a while. 15:08:28 .. Looks like they want to take it to the next stage and discuss actual spec changes, and TTWG 15:08:33 .. is one of the affected groups I think. 15:08:54 .. 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 Gary: I will not be. 15:09:20 Nigel: Are there any other specific agenda topic requests right now? 15:10:25 .. The other two agenda topics that I recalled DAPT and IMSC-HRM implementations 15:10:42 .. As last year for DAPT I would hope to make some progress if Cyril is present. 15:11:00 Cyril: I will not be there in person but can wake up early to join discussions. 15:11:40 .. The Media WG meets from 1400-1900 (on whichever day of the week) to accommodate people on the West Coast. 15:12:01 Gary: I just checked - they meet on Monday afternoon, and MEIG meets on Monday morning. 15:12:48 Nigel: I don't think I've received feedback on DAPT or IMSC-HRM yet 15:13:00 Pierre: I've had some interest from folks who want me to bug them in September. 15:13:13 .. One major platform ran imschrm on a big part of their library. 15:13:22 .. It turns out that a bunch of their IMSC documents were actually invalid. 15:13:36 .. We're in the process of making sure that all the failures were not due to HRM failures. 15:13:50 Cyril: Syntactically? 15:14:06 Pierre: Yes, they were invalid syntactically - all the failures were not HRM related. 15:14:39 Nigel: Were they the sort of syntax errors you might expect to be valid reasonably? 15:15:12 Pierre: One of the issues was that 29.97 framerate content had frame counts of 30 occasionally. 15:15:16 .. We're working through that. 15:15:22 .. I expect mid-late September to have additional results. 15:15:45 Nigel: Does that mean we have no IMSC or IMSC-HRM topics for TPAC? 15:15:50 Pierre: I'm not aware of anything. 15:16:43 Andreas: One more possible topic. Currently some standards orgs are working on liaisons that may 15:16:55 .. reach TTWG and cause an agenda topic. We can decide when it arrives. 15:17:01 Nigel: Thank you for the warning. 15:17:14 .. In that case we have a small number of topics for the Chairs to arrange into a schedule. 15:17:16 .. Thanks all. 15:17:25 .. Anything else on TPAC planning? 15:18:20 Subtopic: Joint meetings 15:19:05 irc has joined #tt 15:19:19 Nigel: On the Monday 11:50-12:35 Spanish time, joint between TTWG, MEIG and (I thought) Media WG. 15:19:32 cpn has joined #tt 15:19:56 .. 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 -> https://docs.google.com/presentation/d/1sadWsW1NZkfjlUdZ5FkXa_taUCzp1jyBNtemqY2WXgE/edit?usp=sharing MEIG agenda slides 15:20:55 Gary: We had previously brought up a discussion about the Text Track API but 15:21:02 .. I don't think anyone is ready to talk about that because I think, 15:21:11 .. especially because of my circumstances, it fell on the floor. 15:21:45 Nigel: Yes, that is a shame, however the Text Track Cue API discussion might help that along potentially. 15:21:59 Gary: Yes, that definitely covers a portion of our big ideals. 15:22:22 Nigel: Let us know if there's anything else to discuss in that joint meeting. 15:22:49 .. The next joint call we have is on the Thursday afternoon, with APA and MEIG, 14:30-16:30 Spanish time. 15:23:22 .. Chris previously put together a short agenda of bullet points which I think we've circulated here before. 15:23:29 .. I don't have it to hand right now. 15:23:58 .. I propose we re-circulate that offline. 15:25:22 .. I think we normally put together an agenda page that's more easily consumable in one place by attendees 15:25:28 .. so I should give myself the action to do that. 15:26:17 -> https://github.com/w3c/ttwg/issues/265 Prepare agenda page for TPAC 15:26:34 Topic: IMSC-HRM 15:26:51 Nigel: Pierre, you mentioned this at the front of the meeting. Anything more to say? 15:27:03 Pierre: No, based on encouraging commitments I expect results at the end of September. 15:27:07 Nigel: Great, thank you. 15:27:25 Pierre: Unless we discover that everyone has invalid IMSC libraries! That would be a bigger issue. 15:27:41 .. It is an issue because it makes testing the HRM difficult. 15:29:05 Nigel: There's a wider point here about the technical quality of tools. 15:29:11 .. I often see issues that need ironing out. 15:29:25 Pierre: Maybe there's an opportunity to make further progress on fixing invalid file production. 15:29:39 [Pierre drops off the call] 15:29:51 Topic: DAPT 15:30:19 Nigel: I haven't seen anything over the last few weeks. Cyril, have you? 15:30:33 Cyril: No, I stopped on this after the HR forms. I need to pick it up again. 15:30:47 .. You had some suggestions about the explainer, Nigel, which I need to action. 15:31:40 .. Maybe I could do the internationalisation request pointing to the draft explainer and then fix it? 15:31:53 Nigel: I don't think the changes I suggested were huge. 15:32:08 Cyril: In that case I can do them today or tomorrow and then make the request. 15:32:28 .. Also I sent messages to studio contacts to see if they have any opinions and can contribute comments. 15:32:35 .. I don't know if it will lead to anything. 15:32:48 .. I reached out to Disney, Warner, Apple, CableLabs and I think one more. 15:33:05 Nigel: Would you be able to add those to the Outreach log on the wiki page? 15:33:08 Cyril: Yes, I will. 15:33:30 Nigel: I also got around to contacting MESA today - thank you to both Matt and Pierre for providing details. 15:33:55 .. I added that to the Outreach log also. 15:34:31 .. 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 .. 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 .. We asked for responses by 10th September. 15:35:19 cpn has joined #tt 15:35:35 Cyril: You will not get a response from MPEG - I can tell you the request was received and reviewed, 15:35:38 .. and no action taken. 15:35:51 Nigel: That's fine, we've done what we needed. 15:37:03 .. I think I am expecting a response from ITU though, need to check. 15:37:17 .. I know they received the message and I think they discussed it. 15:37:44 .. Anything else to discuss re DAPT right now? 15:37:50 Cyril: I can't think of anything at the moment. 15:38:34 Topic: Meeting close 15:38:41 Nigel: We've completed our agenda, thank you everyone. 15:38:50 .. Next meeting will be in Seville, see you there, in person or remotely. 15:38:59 .. [adjourns meeting] 15:39:35 i/..
