For WebVTT, we had questions whether we could call vendor prefixes as implemented/implementable for the IR. It would be good to get input from the CSS WG in regard to whether a vendor-prefixed property could be considered acceptable.

The Timed Text Working Group just discussed Discussion points for CSS WG at TPAC 2019 #52.

The full IRC log of that discussion

<cyril> Topic: Discussion points for CSS WG at TPAC 2019 #52
<cyril> github: https://github.com//issues/52
<cyril> nigel: the list as it stands has a bunch of CSS issues and one TTML one at the moment
<cyril> ... the TTML one is about text-combine
<cyril> ... then shearing
<cyril> ... then equivalent of multiRowAlign
<cyril> ... then about background area with fillLineGap
<cyril> ... and for that one there is a proposed solution
<cyril> ... then padding at start and end of line
<cyril> ... but the issue is closed
<cyril> ... and last one is images with layout information, like Apple Pay logo
<cyril> ... I think there is another one about accessibility
<cyril> ... there is a CSS WG issue which concerns making something invisible on a visual presentation but visible to screen readers
<cyril> ... there seem to be quite a few requirement on this
<cyril> ... CSS WG issue 560
<nigel> -> https://github.com/w3c/csswg-drafts/issues/560 [css-display] create a display property value for visually hiding an element while making it available for AT #560
<cyril> ... and that is connected to an IMSC issue that I raised recently
<cyril> ... to expose burned-in narrative text to a screen reader
<cyril> ... sighted people can see it but we want to put that in a ARIA live region
<cyril> rrsagent, pointer
<RRSAgent> See https://www.w3.org/2019/09/05-tt-irc#T15-02-25
<nigel> rrsagent, make minutes
<RRSAgent> I have made the request to generate https://www.w3.org/2019/09/05-tt-minutes.html nigel
<nigel> Regrets- Glenn
<nigel> Regrets+ Glenn_first_hour
<cyril> pal: we also issue 44 from IMSC
<cyril> nigel: it is in the GitHub list
<cyril> nigel: about TPAC planning, I have an email from Alan, one of the CSS WG chairs
<cyril> ... proposing at 9:30 on Tuesday morning
<cyril> ... I'm going to say yes
<cyril> nigel: regarding the M&E IG, they listed 2 topics
<cyril> ... but there are lot more topics we could talk about
<cyril> ... live, karaoke, danmaku, ...
<cyril> ... and we could think about MSE and text tracks
<cyril> ... because MSE only supports audio/video
<cyril> ... those are my suggestions
<cyril> ... but we have a limited amount of time
<cyril> ... are there other topics or prioritization views?
<cyril> cyril: when will the new text track api be discussed
<nigel> -> https://www.w3.org/2011/webtv/wiki/Face_to_face_meeting_during_TPAC_2019#16:00_-_17:00_Timed_Text_Working_Group_joint_meeting M&E IG agenda
<cyril> pal: on wednesday
<cyril> nigel: there is a request for break out sessions and a request for demo
<cyril> ... do we want to raise the text track api with the M&E IG?
<cyril> cyril: no
<cyril> gkatsev: we need to check what is the overlap between the M&E IG, the Media WG and the TTWG
<cyril> nigel: that's exactly the sort of thing that the M&E IG should discuss, I'll ping Chris
