Nigel: Apologies for the late start!

This meeting

Nigel: Today, we have: TPAC (including demos?), IMSC, TTML.

Thierry: Also David Singer requested I send a reminder for the WebVTT review. It sounds
... reasonable but I want everybody's opinion because it's a bit of a clash with the recent
... request we've had for TTML2, but I think we have no other solution.

Nigel: Okay we'll add WebVTT to the agenda.
... Any other business or particular points to cover today?

Pierre: I need to drop off no later than 1 hour from now.

Mike: I'm also conflicted at the top of the hour.

Nigel: Okay let's go then!

TPAC

Nigel: Dominique reminded me that in June I offered that the TTWG would like to present a demo during the TPAC demo session on the Wednesday.
... What I proposed originally was that we demonstrate the styling features in TTML that
... we have and would like to see implemented also in CSS, as it's a good forum for
... disseminating that information and driving interest.
... What do you think? Is that a good idea?
... I don't mind doing it, especially if I can have some help putting it together - I guess
... the thing to do would be to show the features that we think are somehow highest in
... priority.

Pierre: Okay, yes.
... What about using imsc.js as the basis for that? Showing all the workarounds we
... had to do to achieve the desired effects?

Nigel: Yes, sounds good.

Pierre: If we just complain for 30 minutes it wouldn't look great!

Nigel: +1

Pierre: We can think about that, find a way to make it both fun and instructive, and
... highlight things we'd like to do that are difficult now.

Nigel: Sounds good to me.

Pierre: We can work offline and see if we can find a way to do it.

Nigel: Okay, let's do it. Anyone else want to be involved?
... Moving on to the agenda.

TPAC TTWG schedule wiki page

Nigel: Thanks for adding your names!
... Looking at the agenda, I don't think anyone has added anything yet, so please could
... we focus on it next week?

<scribe> ACTION: nigel Add TTWG TPAC2017 wiki page to next agenda by 2017-09-12 [recorded in http://www.w3.org/2017/09/07-tt-minutes.html#action01]

<trackbot> Created ACTION-505 - Add ttwg tpac2017 wiki page to next agenda by 2017-09-12 [on Nigel Megitt - due 2017-09-14].

IMSC

Nigel: I wanted to note that on behalf of BBC I've posted our gstreamer patch as an
... implementation on the implementation report page for IMSC 1.0.1

Pierre: Thanks for posting that

Nigel: It'd be good to have another pair of eyes verify the screenshot, because there's
... subtlety there and it's good to have an independent view not from the contributing
... organisation.

Pierre: I'll have a look.

Nigel: Thank you

Glenn: The two screengrabs look fine to me.

Nigel: Great, thank you.
... Now the pressure is on to find a second implementation...

Glenn: We have support for activeArea already in TTV but it's just parsing it and verifying
... its correctness.

Nigel: Formally, I think that's all that's needed.
... If you could send notification of that formally to the group that would be really helpful.

Glenn: Okay, sure.

Nigel: Thank you.

TTML2 Review

action-503?

<trackbot> action-503 -- Thierry Michel to Send a reminder to groups for ttml2 review by 8th september -- due 2017-08-17 -- OPEN

<trackbot> http://www.w3.org/AudioVideo/TT/tracker/actions/503

Nigel: Thierry, I think you've done this?

Thierry: Yes I have.

Nigel: Thank you!

close action-503

<trackbot> Closed action-503.

Glenn: I've added horizontal review "comment disposed" to the 8 closed issues previously
... labelled "horizontal review comment". This marks disposal of comments received during
... the review process. For the others it wouldn't harm to have a label indicating that the
... WG has reviewed it.

Nigel: Do you mean to indicate the WG has agreed the disposition and we are awaiting confirmation from the commenter?

Glenn: It would probably be useful to note that the WG reviewed the non-review issues
... from within the group also. There were a number of issues posted by members that were
... not marked as review comments originally. I'd say most of our issues in the past have
... fallen into that category.
... The alternative is I change the new label just to "WG disposed" and use that for all of
... the items that the WG has reviewed.
... It was not my intent to mark that we have had confirmation of the disposition from the commenter,
... just that the WG has agreed what to do.

Nigel: My interpretation is that we need a different label for "WG disposition agreed" and the
... current "comment disposed" issue means that we have given a sufficient opportunity for
... the original commenter to feed back on the WG disposition.
... The main user for these labels will likely be Thierry. Does this make sense to you Thierry?

Thierry: Yes, I'll have a look and check it makes sense and tweak the labels if needed.

Nigel: It might be useful to put together a wiki page explaining the process we are using
... and what labels we are putting on GitHub issues to track the (not particularly changed)
... process instead of using Dom's old web tool.

Thierry: Okay, you can give me an action for that - I've done some work already on WebVTT similarly.

<scribe> ACTION: Thierry Draft a wiki page explaining our review and disposition steps and labels [recorded in http://www.w3.org/2017/09/07-tt-minutes.html#action02]

<trackbot> Created ACTION-506 - Draft a wiki page explaining our review and disposition steps and labels [on Thierry Michel - due 2017-09-14].

Thierry: Once we have these labels on GitHub we will be able to filter on the labels and
... generate automatic dispositions of comments, or at least a list of agreed and not agreed comments?

Nigel: Exactly, yes.

WebVTT review feedback

Thierry: Nothing really exciting here! As Nigel said last week, I had reminded the TTML2
... review to the W3C groups we have dependencies with and horizontal review and external
... groups, and TTML2 review ends on Sep 30. David Singer saw this and our discussion and
... asked me if I could do the same for WebVTT, and I think that's fair enough. The review
... ends on 22nd September for WebVTT, but last week Nigel you had raised a concern about
... having two reviews simultaneously and that it could be confusing to receive such requests
... for review for two different formats within the same week but I don't see how we can
... avoid that unfortunately.

Nigel: Neither do I!

Thierry: So far we have no comments from external groups either for TTML2 or WebVTT.
... One or two groups have responded that they will process it during an October meeting,
... but that's the only kind of answer we got (for both TTML2 and WebVTT), so a reminder
... is certainly necessary.
... My question is: is anyone against me taking that action?
... (but I think it would be unfair to say no!)

Nigel: It seems that nobody wishes to be unfair, so I think you can go ahead Thierry.

Thierry: Okay. Also Nigel just to mention that Daniel was a bit surprised about all the
... messages to team-liaisons, so he asked for a single summary email listing all the groups
... to which the reminders had been sent. So I will not copy team-liaisons on purpose this time.

Nigel: OK, thanks, that makes sense.

Meeting close

Nigel: We've completed our agenda for today, and have no other business so I'll adjourn
... the meeting. Thanks everyone. Next week, let's discuss TPAC agenda please.
