AOB? 14:07:52 group: no AOB 14:08:09 i/nigel: This/Topic: This meeting 14:08:50 nigel: I haven't managed to fix up the minutes from last week - hopefully I'll be able to do that tomorrow. 14:09:05 ... In the meantime did anyone have any changes to make based on the draft minutes? 14:09:10 group: No changes 14:09:23 nigel: In that case it's mainly a tidying job not an editorial one. 14:10:08 nigel: So for today we'll look at actions and I'll set aside some time for WebVTT as there's been progress there. 14:10:12 pal has joined #tt 14:11:25 + +1.650.458.aacc 14:11:26 -glenn 14:11:37 glenn: I'm going to have to drop off this meeting; no progress on actions or issues to report. 14:11:48 zakim, aacc is pal 14:11:48 +pal; got it 14:11:49 zakim, i am aacc 14:11:49 sorry, pal, I do not see a party named 'aacc' 14:13:36 Topic: Action items 14:13:50 action-378? 14:13:50 action-378 -- Pierre-Anthony Lemieux to Draft smpte request including dispositions from action-369 and backgroundcolor initial value question -- due 2015-03-05 -- OPEN 14:13:50 http://www.w3.org/AudioVideo/TT/tracker/actions/378 14:14:45 nigel: Pierre has posted a draft for review: https://docs.google.com/document/d/1ohVIVM_lcsWooOPIsfnjHS7PnbRdON_ygydgo2V7fB4/edit 14:15:12 nigel: Thanks for doing that. 14:15:26 pal: Inline space was missing from nigel's draft. Was that just an omission. 14:15:31 s/on./on? 14:16:12 nigel: No particular reason - most likely I just didn't notice it in the original message from SMPTE. 14:16:39 pal: I used the latest message from SMPTE from January that was sent to public-tt rather than the 14:16:47 ... earlier one that was sent to member-tt. 14:17:00 nigel: That may be the difference then. 14:18:07 pal: SMPTE ST428-7 specifies character rotation on any character but the TTML2 spec only allows it on 14:18:20 ... on normally horizontal characters in vertical writing modes. 14:19:37 nigel: We need to make clear that SMPTE can come back to us if they have use cases that we haven't 14:19:40 ... considered. 14:20:54 pal: Exactly. We could ask generally for SMPTE's responses or specifically request a request for each item. 14:21:14 nigel: I'd like to make it clear that we'd like a response on each item as this is very similar to a request 14:21:20 ... for wide review type response. 14:23:27 pal: We shouldn't hold open the issues until SMPTE has responded. 14:23:53 nigel: Agreed - we should close these issues and if SMPTE or anyone else comes back with new problems 14:23:57 ... we can open new issues. 14:24:12 pal: [drafts specific request] 14:26:43 nigel: The dispositions tool generates email text that looks like: 14:26:48 ... "The Working Group's response to your comment is included below. 14:27:21 ... Please review it carefully and *let us know by email at [address] if you agree with it or not 14:27:33 ... before [date]*. 14:28:12 pal: I would keep it less formal and provide this as a heads-up - if SMPTE has formal comments then 14:28:19 ... they can send them or wait until wide review. 14:28:49 nigel: Yes, the original comments predate the FPWD so they can't be construed as any kind of wide 14:28:56 ... review of TTML2, more of TTML1 if anything. 14:29:53 nigel: Okay let's keep it less formal for now. Current wording is 14:29:55 ... "W3C TTWG looks forward to SMPTE’s feedback on these actions, if any, and to a continued collaboration." 14:32:15 pal: I created the inline space text based on my understanding of ipd. 14:33:12 nigel: That disposition text looks good to me. 14:33:40 ... Since Glenn has written the ipd part of TTML2 it would be good to get his go-ahead for this disposition. 14:33:57 Action: glenn Review Disposition text for Inline space/ipd for SMPTE 14:33:57 Created ACTION-399 - Review disposition text for inline space/ipd for smpte [on Glenn Adams - due 2015-04-23]. 14:34:28 nigel: Once that action is complete then in my view we can send this to SMPTE via Mike and close the 14:34:32 ... outstanding issues. 14:35:11 nigel: I've marked action-378 as pending review. 14:35:28 Action-378: Action-399 created specifically for Glenn to review ipd response 14:35:28 Notes added to Action-378 Draft smpte request including dispositions from action-369 and backgroundcolor initial value question. 14:37:38 nigel: Let's quickly step through the next actions... 14:38:01 nigel: On Action-390 and 391 that's in progress - I'm held up with some CSS issues right now. 14:39:16 courtney: I think David Singer has the dispositions for WebVTT covered but haven't talked to him about it re Action-394. 14:39:26 nigel: He sent a spreadsheet around earlier in the week. 14:40:21 nigel: There's been a bit of email conversation between me, David, Thierry and Silvia about this, offlist. 14:40:33 ... So its safe to say progress is being made. 14:41:12 tmichel: The Accessibility WG said they're working on the WebVTT review and will come back with a date. 14:41:21 ... That was the last message from Julie I think. 14:41:27 nigel: So we don't have a date for a date? 14:41:33 tmichel: I'll wait a week and then ping them again. 14:42:54 issue-397? 14:42:54 Sorry, but issue-397 does not exist. 14:42:57 action-397? 14:42:57 action-397 -- Pierre-Anthony Lemieux to Prepare cr2 transition version (after closing one remaining issue on imsc 1) -- due 2015-04-17 -- OPEN 14:42:57 http://www.w3.org/AudioVideo/TT/tracker/actions/397 14:43:04 pal: On Action-397, we haven't resolved the outstanding issue with begin yet. I tried to go through 14:43:16 ... SMIL and the best I found is that if begin is not specified then it's up to the time container. If you 14:43:34 ... recursively follow that all the way to the top, then the begin of body is the begin of the external 14:43:42 ... time container. Is that your understanding too? 14:43:44 nigel: Yes. 14:45:04 pal: I expect to have a resolution to that very shortly. 14:46:06 nigel: There is a use case for no begin time, which is when you just want the document to be 14:46:22 ... processed as soon as possible. This might happen in live use cases. Of course you don't really know 14:46:40 ... when that display time will start. 14:46:55 pal: If you have multiple consecutive documents then it's a lot easier if you specify begin times. 14:47:24 nigel: Right, but that does give the container freedom to resolve the begin and end of each document. 14:48:55 nigel: Maybe we should leave IMSC 1 as it is or add a note saying that if you have a time container 14:49:59 ... then watch out for the unresolvable time scenario. 14:50:42 pal: Alternately an external time container that says 'start at 5s' should define when t=0 is. 14:51:26 nigel: For me, I think requiring a begin time is a bit too limiting, but highlighting the danger would be good. 14:53:50 pal: Okay then a note highlighting the time resolution feature of TTML and the potential danger could 14:53:54 ... be the way to go. 14:54:11 nigel: You could say that time containers that only indicate 'start playing 5s in' should treat the 14:54:28 ... resolved begin time as 'now - 5s' and step in as though that had happened. 14:55:08 pal: I'll draft something suggesting that an absent begin should be treated as begin at 0. 14:55:15 nigel: I'm happy to review that when I see the wording. 14:56:12 issue-382? 14:56:12 issue-382 -- Require a computed non-indefinite begin time -- open 14:56:12 http://www.w3.org/AudioVideo/TT/tracker/issues/382 14:56:23 nigel: By the way, that discussion above related to issue-382. 14:57:14 -tmichel 14:57:17 -[Apple] 14:57:22 -Frans 14:57:29 Topic: WebVTT 14:57:46 nigel: I just want to make sure that there's an opportunity to raise any further WebVTT points not already 14:57:49 ... raised? 14:57:56 courtney: Not from me just now. 14:58:43 nigel: We have no AOB, so I'll adjourn now.
