16:21:10 <Zakim> agendum 5 -- Discuss Media Stream Content Hints https://lists.w3.org/Archives/Public/public-apa/2021Jun/0001.html -- taken up [from becky]
16:21:30 <janina> scribe: janina
16:21:58 <janina> Lionel_Wolberger: Media Stream Content Hints
16:22:18 <janina> Lionel_Wolberger: Provides an optional hint to give consumers info on making choices
16:22:52 <janina> Lionel_Wolberger: e.g. your audio codec in a Zoom call, phps a different codec?
16:23:01 <janina> Lionel_Wolberger: same for video
16:23:29 <janina> Lionel_Wolberger: Content hint definitely helpful for decoders
16:23:49 <janina> Lionel_Wolberger: phps should be clearer this could be beneficial to AT users
16:24:20 <janina> Lionel_Wolberger: Also, these hints are actually authored, so the hints could be authored with pwd in mind
16:24:33 <janina> Lionel_Wolberger: Also, spec makes no mention of support files
16:25:03 <janina> Lionel_Wolberger: No support for possibly linked media, e.g. 3rd party described video
16:25:25 <janina> becky: Is this hint for people who create/modify UI? How provided to user?
16:25:32 <janina> Lionel_Wolberger: Don't think in the UI
16:25:41 <janina> becky: not for end users?
16:25:44 <janina> Lionel_Wolberger: Yes
16:25:52 <janina> becky: so at would take advantage
16:25:53 <janina> Lionel_Wolberger: yes
16:26:13 <janina> Lionel_Wolberger: not an UI/UX spec, but great impact on UI/UX
16:26:26 <janina> Lionel_Wolberger: also thought of 2 use cases not covered ...
16:27:12 <janina> Lionel_Wolberger: e.g. video content hints -- motion, you want to preserve display of motion
16:27:34 <janina> Lionel_Wolberger: so if motion with transcription/caption, those could become blurry
16:27:53 <janina> q+ to talk about captions
16:28:39 <JF> Q+
16:28:58 <becky> ack janina
16:28:58 <Zakim> janina, you wanted to talk about captions
16:29:15 <becky> ack JF
16:29:15 <janina> janina: asks about captions, still burned in?
16:29:24 <janina> jf: still far too common, e.g. facebook
16:29:34 <janina> jf: So agree with this use case
16:30:08 <janina> Lionel_Wolberger: suggests can make the observation that we prefer not burned in
16:30:22 <Fazio> good point
16:30:25 <janina> jf: Notes it's possible to have the one atop the other--a mess
16:30:57 <janina> Lionel_Wolberger: also thinking of ua and dom ...
16:31:11 <janina> Lionel_Wolberger: does the aapi pass this on?
16:31:34 <janina> Lionel_Wolberger: should we require ua passes hint to aapi
16:31:49 <janina> becky: not necessarily the specification's responsibility?
16:33:14 <JF> Q+ to ask about metadata schemes?
16:33:23 <janina> janina: so it's exposed somewhere
16:33:28 <janina> Lionel_Wolberger: yes, in the ua player
16:33:41 <becky> ack jf
16:33:41 <Zakim> JF, you wanted to ask about metadata schemes?
16:34:02 <janina> jf: perhaps it should be addressed in metadata -- via the containing document
16:34:19 <janina> jf: maybe we need to promote a better authoring pattern
16:34:24 <becky> q?
16:34:49 <janina> Joshue108: at may variously use, or not info from the dom
16:35:22 <janina> Joshue108: still variants, the old osm plus aapi still out there
16:35:46 <janina> becky: you wouldn't know at the doc level
16:36:03 <janina> becky: video may be coming from elsewhere, and containing page wouldn't know
16:36:11 <janina> becky: so it has to be part of the stream
16:36:18 <janina> jf: good point
16:36:29 <janina> jf: maybe embedded in the stream container
16:37:37 <janina> [discussion on next steps]
16:39:35 <JF> MP4 files can contain metadata as defined by the format standard, and in addition, can contain Extensible Metadata Platform (XMP) metadata. (source:: https://en.wikipedia.org/wiki/MPEG-4_Part_14)

16:45:17 <JF> Metadata Pt. 3 https://schema.org/caption
16:45:47 <Lionel_Wolberger> becky: Permissions can limit browser features
16:46:02 <Lionel_Wolberger> ... concern that this spec might be too low level
16:46:24 <Lionel_Wolberger> ... APA concern if browser capabilities are turned off
16:46:39 <Lionel_Wolberger> ... since turned off for everyone, it's not an a11y issue
16:46:56 <Lionel_Wolberger> janina: USB can be turned off? What if the AT is relying on USB?
16:47:11 <Lionel_Wolberger> becky: spatial tracking, picture in picture are both in there
16:49:40 <Lionel_Wolberger> q?
16:51:01 <becky> https://www.w3.org/TR/permissions-policy-1/#examples
16:52:38 <Lionel_Wolberger> Lionel_Wolberger: There are examples in the policy spec
16:53:42 <Lionel_Wolberger> becky: Add that implementers should be aware of the possibility of accessibilty features that rely on features that are switched off, e.g. an AT relying on USB
16:53:52 <Lionel_Wolberger> janina: If they are focused on iFrames thats fine
16:54:01 <Lionel_Wolberger> becky: They are talking about cross-browser issues as well
16:55:23 <Lionel_Wolberger> janina: Can we use this to disallow automatic audio auto-play
16:55:36 <Lionel_Wolberger> Lionel says to Janina and becky +1 to no audio and +1 to no auto-play
