Notes added to action-399 Review disposition text for inline space/ipd for smpte.
14:16:37 [Zakim]
+Plh
14:16:38 [nigel]
glenn: I'll take a quick look at that now.
14:17:06 [nigel]
... I'll comment that it would be useful to comment that in horizontal mode ipd means width and in
14:17:14 [nigel]
... vertical mode it means height. Otherwise it's okay.
14:17:35 [nigel]
nigel: Looks like there's some editorial work to do to close off Action-399 and Action-378.
14:17:51 [nigel]
action-390?
14:17:51 [trackbot]

14:18:37 [nigel]

14:18:37 [trackbot]

14:19:34 [nigel]
nigel: I've sent the details - I think that pal had a question for plh?
14:19:51 [nigel]
pal: Yes. Mercurial is good for text files - here there's a relatively large video file to support the
14:20:04 [plh]
media.w3.org
14:20:07 [nigel]
... completion of those tests. Can W3C host those? How best to proceed?
14:20:27 [nigel]
plh: Send me the files or links and I'll upload them to the dedicated server.
14:21:02 [nigel]
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.

14:22:33 [nigel]
nigel: These particular videos happen to be .flv - I'm not sure why. Is there any problem with that format?
14:22:47 [nigel]
plh: No problem for us to host it, but not all players might be able to play it back.
14:23:09 [nigel]
nigel: I've played it successfully with VLC and on at least one browser (can't remember which).
14:23:34 [nigel]
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]
nigel: I see there are open actions from the F2F on glenn, tmichel, Andreas, Courtney and David Singer.

pal: On Action-378 there's one comment remaining, from nigel. Can we close that?
14:27:52 [nigel]
nigel: Yes, it used to say that fontVariantPosition does apply to nested spans, and I thought it did not.
14:28:05 [nigel]
glenn: Logically it should apply - it's used for example in maths equations.
14:28:28 [nigel]
nigel: I've removed my erroneous addition in the Google doc and the clarification note.
14:28:35 [nigel]
pal: Now this is ready for the chairs to process.

Topic: WebVTT review feedback
14:31:48 [nigel]
dsinger: We've got the preliminary comments from the a11y group as well as css and i18n and mpeg
14:32:06 [nigel]
... My next step is to move the spreadsheet onto the wiki and add a column for the final disposition
14:32:20 [nigel]
... 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 [nigel]
... dispositions on all the ones on the list.
14:32:38 [nigel]
... We need to have a discussion on them all now.
14:33:17 [nigel]
nigel: Some of the dispositions are currently questions. I'm not sure if they're for us or the commenter.
14:33:37 [nigel]
dsinger: They'll have to get turned into statements otherwise they're not dispositions. Some of them
14:34:02 [nigel]
... are for us to resolve, others for the commenter.
14:35:23 [nigel]
nigel: I wonder what the minimum width is for 'wide review' - for example Andreas's good comments
14:35:27 [nigel]
... are from a WG member.
14:35:43 [plh]
zakim, drop plh
14:35:43 [Zakim]

-Plh
14:35:48 [Zakim]
+Plh
14:35:59 [nigel]
dsinger: There isn't a definition of width here - this is recognised at AB level. The best evidence for
14:36:15 [nigel]
... review is that the spec has been implemented, so I'd like the implementors to comment to the list
14:36:20 [nigel]
... that they have done that.
14:36:41 [nigel]
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 [nigel]
... get the feedback as well as showing what feedback was received, and the dispositions.
14:37:03 [nigel]
dsinger: I will document where I asked for feedback.
14:37:41 [nigel]
dsinger: Courtney, anything more on TTML WebVTT conversion?
14:37:55 [nigel]
Courtney: I met with Andreas and Loretta last week. We now have an updated outline for the mapping
14:38:07 [nigel]
... document. We've divided it up between the three of us. We're hoping to have a first draft to show
14:38:25 [nigel]
... the working group by early July, with the goal of having a final draft for Sapporo.
14:39:18 [nigel]
dsinger: I'm also aware that Kaltura and an open source project (TCF) have some work here.
14:39:36 [nigel]
nigel: What's the plan for working with them? We've already seen some comms with Kaltura.
14:39:56 [nigel]
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 [nigel]
... to get their review as a minimum, so we're informed by the practices of implementation.
14:40:47 [nigel]
Topic: TTML2 Editorial actions
14:40:59 [nigel]
https://dvcs.w3.org/hg/ttml/raw-file/tip/ttml2/spec/ednotes.xlsx
14:42:05 [nigel]
nigel: Glenn put together the above spreadsheet and shared it at the F2F. The idea is to share out
14:42:34 [nigel]
... some of those tasks so that we can get to the next WD of TTML2. We particularly want to share out
14:42:49 [nigel]
... the editorial and example lines, but if anyone wants to volunteer for the technical items that's okay too?
14:42:54 [nigel]
glenn: I've no problem with that.
14:43:17 [Dsinger_]
Dsinger_ has joined #tt
14:43:24 [nigel]
nigel: I sent this out with the agenda - does anyone want first go at taking some of those tasks?
14:44:23 [Dsinger_]
Zakim, who is here?
14:44:23 [Zakim]
On the phone I see Frans, pal, nigel, glenn, Plh, dsinger, Courtney
14:44:25 [Zakim]
On IRC I see Dsinger_, Zakim, RRSAgent, nigel, pal, plh, Frans_EBU, glenn, trackbot
14:44:56 [nigel]
glenn: If someone wants to volunteer without going to the trouble of building the spec with ant, etc
14:45:04 [nigel]
... then giving me the content directly would be fine also.
14:45:22 [nigel]
nigel: I've made it work I think, and it was pretty straightforward, but good to have both options.
14:46:26 [nigel]
nigel: On the "revise system model" do we have an original for that?
14:46:49 [nigel]
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 [Dsinger_]
It is nice to make pictures svg...they can be annotated for accessibility
14:47:11 [nigel]
nigel: I'm happy to revise that - is it just a matter of removing "DFXP" or is there a more fundamental
14:47:13 [nigel]
... change?
14:47:21 [nigel]
glenn: I'll consider that before answering.
14:48:03 [nigel]
nigel: I can also have a go at a bpd and ipd example. Disparity might be better covered by someone
14:48:08 [nigel]
... with more experience in 3D.
14:48:34 [nigel]
glenn: I need to update the disparity section based on our resolution to remove the requirement to use
14:48:51 [nigel]
... the conditional mechanism, so there's a few details there before the example can be completed.
14:49:41 [nigel]
nigel: I think we can base the examples for enhanced padding and text align on span on the IMSC 1
14:49:47 [nigel]
... linePadding and multiRowAlign examples.
14:49:58 [nigel]
glenn: Yes, very likely though the syntax would differ.
14:50:02 [nigel]
nigel: I'm happy to have a go at those.
14:50:27 [nigel]
nigel: I've already done the work on requirement numbers and satisfaction so I don't mind doing those
14:50:29 [nigel]
... as well.
14:51:15 [nigel]
nigel: I didn't understand the note on tts:opacity - it says to show it on content elements.
14:51:30 [nigel]
glenn: In TTML1 opacity only applies to region - for TTML2 we have introduced the use of opacity on
14:51:45 [nigel]
... content elements, so each time an element gets painted into the region it gets the alpha value from
14:51:59 [nigel]
... the opacity value applied to it as the index layers of the region are composited. For example you
14:52:12 [nigel]
... could have different opacity on region, body, div, p and span and they would all composite with
14:52:17 [nigel]
... different alphas.
14:52:39 [nigel]
... It applies to all of the markings created by the element including padding, background, borders, text etc.
14:53:40 [nigel]
nigel: Can I ask everyone to have a look at that spreadsheet and ask any questions or volunteer for
14:53:45 [nigel]
... anything you can do.
