I'll comment that it would be useful to comment that in horizontal mode ipd means width and in 14:17:14 ... vertical mode it means height. Otherwise it's okay. 14:17:35 nigel: Looks like there's some editorial work to do to close off Action-399 and Action-378. 14:17:51 action-390? 14:17:51 action-390 -- Nigel Megitt to Update the multirowalign and linepadding ttml files to have shorter lines of text -- due 2015-04-17 -- PENDINGREVIEW 14:17:51 http://www.w3.org/AudioVideo/TT/tracker/actions/390 14:18:03 action-391? 14:18:03 action-391 -- Nigel Megitt to Update the multirowalign and linepadding pngs to match the ttml -- due 2015-04-17 -- PENDINGREVIEW 14:18:03 http://www.w3.org/AudioVideo/TT/tracker/actions/391 14:18:31 nigel: I've had an email from atai on this - he will review when he returns from vacation. 14:18:37 action-393? 14:18:37 action-393 -- Nigel Megitt to Send pal details of implementation and tests passed so he can create a table in the implementation report -- due 2015-04-17 -- PENDINGREVIEW 14:18:37 http://www.w3.org/AudioVideo/TT/tracker/actions/393 14:19:34 nigel: I've sent the details - I think that pal had a question for plh? 14:19:51 pal: Yes. Mercurial is good for text files - here there's a relatively large video file to support the 14:20:04 media.w3.org 14:20:07 ... completion of those tests. Can W3C host those? How best to proceed? 14:20:27 plh: Send me the files or links and I'll upload them to the dedicated server. 14:21:02 pal: I'll send plh links to the files, and if you send me the links I'll upload them and send you the links. 14:21:27 s/.../pal 14:22:33 nigel: These particular videos happen to be .flv - I'm not sure why. Is there any problem with that format? 14:22:47 plh: No problem for us to host it, but not all players might be able to play it back. 14:23:09 nigel: I've played it successfully with VLC and on at least one browser (can't remember which). 14:23:34 plh: As long as it plays where we want it to play we're good, as it's just for demonstrating the test suite. 14:24:49 nigel: I see there are open actions from the F2F on glenn, tmichel, Andreas, Courtney and David Singer. 14:25:22 +dsinger 14:25:34 Present+ dsinger 14:26:42 pal: On Action-378 there's one comment remaining, from nigel. Can we close that? 14:27:52 nigel: Yes, it used to say that fontVariantPosition does apply to nested spans, and I thought it did not. 14:28:05 glenn: Logically it should apply - it's used for example in maths equations. 14:28:28 nigel: I've removed my erroneous addition in the Google doc and the clarification note. 14:28:35 pal: Now this is ready for the chairs to process. 14:28:57 close action-399 14:28:57 Closed action-399. 14:29:14 -Courtney 14:29:18 close action-378 14:29:18 Closed action-378. 14:29:49 Action: nigel Send SMPTE dispositions from Action-378 to SMPTE (mdolan) 14:29:49 Created ACTION-400 - Send smpte dispositions from action-378 to smpte (mdolan) [on Nigel Megitt - due 2015-04-30]. 14:30:49 +[Apple] 14:31:01 zakim, [Apple] is Courtney 14:31:01 +Courtney; got it 14:31:17 Topic: WebVTT review feedback 14:31:48 dsinger: We've got the preliminary comments from the a11y group as well as css and i18n and mpeg 14:32:06 ... My next step is to move the spreadsheet onto the wiki and add a column for the final disposition 14:32:20 ... and add a trace of all the places I've asked for feedback. I've asked the WG and the CG to generate 14:32:29 ... dispositions on all the ones on the list. 14:32:38 ... We need to have a discussion on them all now. 14:33:17 nigel: Some of the dispositions are currently questions. I'm not sure if they're for us or the commenter. 14:33:37 dsinger: They'll have to get turned into statements otherwise they're not dispositions. Some of them 14:34:02 ... are for us to resolve, others for the commenter. 14:35:23 nigel: I wonder what the minimum width is for 'wide review' - for example Andreas's good comments 14:35:27 ... are from a WG member. 14:35:43 zakim, drop plh 14:35:43 Plh is being disconnected 14:35:43 -Plh 14:35:48 +Plh 14:35:59 dsinger: There isn't a definition of width here - this is recognised at AB level. The best evidence for 14:36:15 ... review is that the spec has been implemented, so I'd like the implementors to comment to the list 14:36:20 ... that they have done that. 14:36:41 plh: I agree with dsinger that there's no minimum width - the best we can do is show that we tried to 14:36:55 ... get the feedback as well as showing what feedback was received, and the dispositions. 14:37:03 dsinger: I will document where I asked for feedback. 14:37:41 dsinger: Courtney, anything more on TTML WebVTT conversion? 14:37:55 Courtney: I met with Andreas and Loretta last week. We now have an updated outline for the mapping 14:38:07 ... document. We've divided it up between the three of us. We're hoping to have a first draft to show 14:38:25 ... the working group by early July, with the goal of having a final draft for Sapporo. 14:39:18 dsinger: I'm also aware that Kaltura and an open source project (TCF) have some work here. 14:39:36 nigel: What's the plan for working with them? We've already seen some comms with Kaltura. 14:39:56 dsinger: Kaltura don't have time to work with the group - I'm talking with the TCF group too. I'd like 14:40:07 ... to get their review as a minimum, so we're informed by the practices of implementation. 14:40:47 Topic: TTML2 Editorial actions 14:40:59 https://dvcs.w3.org/hg/ttml/raw-file/tip/ttml2/spec/ednotes.xlsx 14:42:05 nigel: Glenn put together the above spreadsheet and shared it at the F2F. The idea is to share out 14:42:34 ... some of those tasks so that we can get to the next WD of TTML2. We particularly want to share out 14:42:49 ... the editorial and example lines, but if anyone wants to volunteer for the technical items that's okay too? 14:42:54 glenn: I've no problem with that. 14:43:17 Dsinger_ has joined #tt 14:43:24 nigel: I sent this out with the agenda - does anyone want first go at taking some of those tasks? 14:44:23 Zakim, who is here? 14:44:23 On the phone I see Frans, pal, nigel, glenn, Plh, dsinger, Courtney 14:44:25 On IRC I see Dsinger_, Zakim, RRSAgent, nigel, pal, plh, Frans_EBU, glenn, trackbot 14:44:56 glenn: If someone wants to volunteer without going to the trouble of building the spec with ant, etc 14:45:04 ... then giving me the content directly would be fine also. 14:45:22 nigel: I've made it work I think, and it was pretty straightforward, but good to have both options. 14:46:26 nigel: On the "revise system model" do we have an original for that? 14:46:49 glenn: If we do it would probably be in Visio - I'll look for it and see if I can find it. 14:47:00 It is nice to make pictures svg...they can be annotated for accessibility 14:47:11 nigel: I'm happy to revise that - is it just a matter of removing "DFXP" or is there a more fundamental 14:47:13 ... change? 14:47:21 glenn: I'll consider that before answering. 14:48:03 nigel: I can also have a go at a bpd and ipd example. Disparity might be better covered by someone 14:48:08 ... with more experience in 3D. 14:48:34 glenn: I need to update the disparity section based on our resolution to remove the requirement to use 14:48:51 ... the conditional mechanism, so there's a few details there before the example can be completed. 14:49:41 nigel: I think we can base the examples for enhanced padding and text align on span on the IMSC 1 14:49:47 ... linePadding and multiRowAlign examples. 14:49:58 glenn: Yes, very likely though the syntax would differ. 14:50:02 nigel: I'm happy to have a go at those. 14:50:27 nigel: I've already done the work on requirement numbers and satisfaction so I don't mind doing those 14:50:29 ... as well. 14:51:15 nigel: I didn't understand the note on tts:opacity - it says to show it on content elements. 14:51:30 glenn: In TTML1 opacity only applies to region - for TTML2 we have introduced the use of opacity on 14:51:45 ... content elements, so each time an element gets painted into the region it gets the alpha value from 14:51:59 ... the opacity value applied to it as the index layers of the region are composited. For example you 14:52:12 ... could have different opacity on region, body, div, p and span and they would all composite with 14:52:17 ... different alphas. 14:52:39 ... It applies to all of the markings created by the element including padding, background, borders, text etc. 14:53:40 nigel: Can I ask everyone to have a look at that spreadsheet and ask any questions or volunteer for 14:53:45 ... anything you can do. 14:55:32 -glenn 14:55:34 -Plh 14:55:34 -dsinger 14:55:34 -Courtney 14:55:35 -Frans 14:55:39 -nigel 14:56:01 nigel: I think we've hit all the topics we can discuss today, so let's adjourn and meet same time next week.
