"Poster Issue http://lists.w3.org/Archives/Public/public-html-a11y/2010Dec/0054.html" taken up [from janina] 22:43:14 janina: is there anyone that thinks that alt text needs to distinguish poster form media 22:43:23 s/form/from/ 22:44:12 janina: seems that the poster behaviour functions as a static image and thats what the alt is abouy 22:44:28 eric: john is not here 22:44:44 and his opinion is we need something as a separate discription 22:45:25 judy: whats the point of discussing now? 22:45:46 janina: bringing out the positions 22:46:18 eric: if you are saying that we need a separate description of the 1st frame from the video, i dont agree 22:46:31 janina: we dont need a description of the elemnet 22:46:48 this is what we traditionallly have done is describe images 22:47:22 so if poster is an image then alt and longdesc apply to it 22:47:38 or 1st frame if its functioning as an image 22:48:04 no alt description for the element 22:48:14 eric: I meant a description of the resource 22:48:32 eric; agree author needs alt or longdesc of the media content 22:48:46 eric: but not describe the 1st frame separately 22:49:09 eric: if it needs to be destinct then it should be described as part of the media resource 22:49:39 eric; seems to me that a description of a video describes what you see in the first frame or poster 22:49:56 janina: how does this differ from a static image 22:50:12 eric: video is different tform a static image 22:50:57 janina: sighted user knows its a video how? 22:50:57 eric: if default controls arent shown then it looks the same as an image 22:51:13 if the controls are there then you see them overlaid 22:51:33 janian: browser + AT can recognize the controls 22:51:40 -Eric_Carlson 22:51:40 eric; yes 22:51:59 +Eric_Carlson 22:52:00 janina: so see no need to describe that 22:53:01 prgrammatically ccan determine image from video, so whatever is being shown is all that needs describing - which is a static image 22:53:40 functionally no different than describing an image 22:54:11 eric: johns point is that we need a new child element of the video containing the poster and a description of the poster 22:54:33 eric: agree with Janina, use existing attribute on the element itself 22:54:50 janina: true that alt as an attribute has some issues 22:54:56 for i18n 22:55:15 but thats a separate discussion on enhancing alt 22:56:13 eric: what about autoplay? 22:56:36 janina: can keep that from happening 22:57:20 eric: even if it starts playing on any user action. what does it mean if the description only cvers the static part and the AT gets to it after playback has started 22:57:32 janina: we should try to avoid that 22:58:08 eric: other controls on the page e.g. an element, can start the video playing 22:58:56 so thinking that doesnt make sense to just describe the static representation, should include description of the media and the first frame (if significant) 22:59:35 eric: we cant prevent it, but may be an edge case 22:59:57 image on another part of the screen which starts the video on hover 23:00:05 any script can trigger media element 23:00:24 janina: yes - a problem 23:01:04 wcag requirement is that you can disable that 23:01:11 or stop it 23:01:17 eric: hard to do 23:01:23 iOS has this behaviour 23:01:39 needs an explicit user gesture to start video 23:01:51 must be in a user initiated event handler 23:02:06 but hard to do on desktop, big change 23:02:12 would break content 23:03:03 Judy: I'm worried we might not have anything exlict on this in wcag 23:03:26 possible we have something adequately generic 23:03:34 and a technique would take care of it 23:03:46 eric: best we can do is an authoring guideline 23:03:57 janina: thinking we cant prevent it 23:04:17 judy: except if we have the ability to feed in UA guidelines 23:04:53 eric: my point is that its possible for a UA to prevent autoplay, not honor page authors trequest 23:05:05 but its difficult prevent any script 23:05:20 when is it OK, thats the issue 23:05:52 janina: its a common behaviour, and people like it; but for some its an accessibility issue 23:06:06 eric: but whats to prevent a script running> 23:06:35 kenny: difficult for engineers, but could filter out based on events 23:06:41 eric: wont prevent it 23:06:57 they are attached to media loading 23:07:25 very difficult to determine automatically when its ok and when its not 23:07:39 on iOS script has to be triggered from user gesture 23:07:50 but its hard to implement; and breaks a lot of content 23:08:26 lots of bug reports on iphone because of this 23:08:43 causes authors to write new scriptsa for the phone 23:08:54 wont get buy in on such a change 23:09:15 janina: maybe its a new user requirment 23:09:42 judy: wcag doesnt say anything directly relevant to preventing autoplay 23:10:10 the relevant place is UAAG, and has a clause on separate selection form activation 23:10:14 as a user option 23:10:45 partial relevance 23:10:53 and another one about event handlers 23:11:17 maybe needs to revisited if we have feedback on autoplay 23:11:56 kenny: Q: is there a possibility of dealing with it in browser to give screen reader user a means to stop the video on request 23:12:18 judy: both probably, but we dont have both covered 23:12:26 eric; technically possible 23:12:44 but custom controls wuld have to have a case to deal with it 23:13:27 on page with default controls tho could work 23:13:53 janina: strayed form the poster issue? but identified an important issue 23:14:02 need to articulate it better 23:14:36 janina: that media does not start automatically unless user asks for it 23:15:03 not bringing focus on another element etc. setting for specific users 23:15:20 eric: this is a problem that cant be solved cleanly 23:15:35 we will prevent people from writing custom controls 23:16:14 kenny: so if browsers give a keystrok to stop, it should be possible now that video is native 23:16:35 may be a more robust solution 23:16:43 and its only one new gesture to learn 23:16:54 eric; could work. 23:17:39 sean: but if the video starts then the poster is no longer visible 23:17:51 eric: so the description needs ot be of the whole resource 23:18:05 so its always relevant 23:18:21 janina: ok, hadnt thought of that 23:18:44 kenny: alt text for the video must describe the video, but not frame by frame 23:19:25 janina: description for poster would need to dissapear 23:19:46 would make sense if the video is paused on different frame 23:19:51 wouldnt 23:20:25 janina: more fruitful conversation tan expected 23:20:45 summary: 1 mechanism or multiple mechanisms 23:20:54 point of disagreement 23:21:53 point 2: jf and janina have discussed offline, he's cncernd that the poster may be irrlevant to what the movie is 23:22:18 if thats the case then its the case for the sighted user too 23:23:14 expecting there is some thing which tells you what the video is, separate from any poster image 23:23:20 like a title 23:23:29 judy: a name is the most consistent thing 23:23:47 eric: majority of web content just has the first frame of the file 23:23:57 so not that helpful to sighted user either 23:24:12 janina: should try to solve bad authoring 23:24:20 should not 23:24:38 but john may have a different perspective 23:24:46 have we missed anything?
