21:51:28 Silvia its about adding ID and kind 21:51:53 to get a unique identifier to create a fragment url 21:53:05 Sean: should also have a getFragmentIRL function 21:53:17 Siliva: agree, but ID is still needed 21:53:30 Sean: have both 21:53:51 Eric: prefer to not have the function 21:54:14 problem is that there are files for which the URL for the track is not the same as the parent movie 21:54:23 which is another file on the server 21:55:36 asking a track for a URL, if its a reference to a different file; this needs to be resolved 21:55:57 it is also a problem that the fragment spec is not final 21:56:24 it seems to be something that could be done in a JS library/ 21:56:48 Silvia can find outr which tracks exist 21:57:04 composing the fragment url to combine in one URL 21:57:49 Sean: do we need additional information? 21:57:59 Eric: Asking a track for a reference to itself 21:59:02 refering to the track from the outside is unambiguous 21:59:12 from the inside there is a possibility of confusion 21:59:38 defintion of the attribute needs to say what it refers to 21:59:54 Silvia getID we definitley want 22:00:05 get URL may be a convenience 22:00:20 we dont need to agree on it now to resolve 152 22:03:00 we need to look at the current src to see if its adequate prefix to a #id 22:03:04 +1 to @kind 22:03:20 Silvia: kind is required to discover what the content is intended for 22:03:32 +1 to @kind 22:03:44 all: agree kind is necessary 22:04:12 Eric: one problem is how we define the media information to a kind 22:04:27 doesnt exist in in MP4 and Quicktime 22:04:36 we are working on a proposal 22:04:46 but hasnt been defined yet 22:04:57 secondly, no authoring tools to let you add it 22:05:10 maybe some command line tools 22:05:26 so it will be a while before this data shows up in files 22:05:41 but agree its important, but will be difficult for a while 22:05:56 Silvia: need it in the spec for interoperability 22:06:17 JF: if the additional data is in the wrapper, how is it exposed to the player 22:07:40 SIlvia : is the data- attribute appropriate? 22:08:08 eric: we need a mechanism to express a kind of an inband track 22:08:19 this is not on the markup 22:08:29 its in the media 22:09:18 Eric we have a bit of chicken and egg problem, but it will get solved 22:09:56 Silivia: there are slots in media files, but we need time to establish usage 22:10:23 -silvia 22:10:26 Eric: there are fields in Quicktime files, but not standard values 22:11:02 mark: in mpeg-DASH they have been looking at this, and will add the necessary annotations 22:11:02 +silvia 22:11:32 JF: so we do need @kind 22:11:43 did we not have other kinds 22:11:49 Silvia: thise were for text 22:11:54 this is AV 22:12:06 we need to think about other kinds 22:12:43 sean: clear audio sould be a kind 22:13:06 speech only 22:13:55 JF: lang, ISO language codes, there doesnt seem to be consistency 22:14:08 do we need to specify language codes for sign 22:14:24 Silvia: yes the latest ones are fairly complete for sign 22:14:37 so not a problem 22:15:06 Mark: are there others like no repetetive stimulis 22:15:11 non-strobe 22:15:33 Eric: that's not really a kind, but a characteristic of the asset 22:16:00 so slightly orthogonal issues 22:16:20 JF: +1 22:16:35 these issues need to be considered, but its not an @kind value 22:16:50 Eric: D Singer and I have never gotten any traction on it 22:17:04 we cant do it in the next 48 hrs 22:17:26 JF: do we have a final list 22:17:53 Sean: should this be an open ended list 22:17:59 Silvia: yes 22:18:04 JF: agree 22:18:25 Judy: can you restate the issue 22:19:13 eric: there is a need for content authors to decalre tha accessiility reqs that content meets, but also markup content to let the UA pick the content the user does not want 22:19:44 do the UAAG WG have anything relevant 22:20:53 Eric: the issue is that the content author needs to be able to describe the content 22:21:47 Mark: MPEG-DASH is defining these roles, and sent a liaason on this question and multiple roles can be assigned 22:22:01 Judy: can I be put on that htread 22:22:17 Mark: the liason should come formally soon 22:22:29 it was addressed to this group 22:23:16 Silvia: I think there are some open issues, but we can maybe pursue them separately 22:23:21 maybe as a media query 22:24:05 Judy: the restatement was helpful 22:24:21 can you send the materials 22:25:07 Silvia: added clear audio 22:25:17 JF: done with kind 22:25:23 next item, loop 22:25:43 Silvia: loop is currently disabled for a combined set of elements 22:26:01 we have discussed how it should work 22:26:17 maybe we can leave it for now and discuss with ian 22:26:29 do we actually want loop to be solved 22:26:50 JF: straw poll of opinion 22:27:01 Eric: we should hhave it 22:27:19 Frank : agree 22:27:26 Sean: no reason not to 22:27:37 mark, Judy: no opinio 22:27:44 consensus we should have it 22:28:01 net item : autoplay 22:28:37 Judy can we be clear on the question 22:28:58 eric: should we ever allow autoplay for a group of media resources 22:30:14 silvia: we have it in the requirements 22:30:31 its done by single and inband multi track 22:30:39 but not by slaved elements 22:30:50 do we want it 22:31:10 Judy: current wording?

22:39:24 Eric: no 22:39:47 its about user agent preferences 22:41:28 A http://www.whatwg.org/specs/web-apps/current-work/multipage/video.html#mediacontroller is a blocked media controller if the http://www.whatwg.org/specs/web-apps/current-work/multipage/video.html#mediacontroller is a http://www.whatwg.org/specs/web-apps/current-work/multipage/video.html#paused-media-controller, or if any of its http://www.whatwg.org/specs/web-apps/current-work/multipage/video.html#slaved-media-elements arehttp://www.whatwg.org/specs/web-apps/c 22:42:09 Judy: need to defer this and go to the other issues 22:42:26 item: some attributes are missing in the controller 22:43:07 Silvia. we had request to add some events, but these relate to the readyState, so we need to decide whether we need a combined readystate 22:43:19 it seems readystate is inconsistent 22:43:39 so perhaps we dont really need it, 22:43:55 but we can wait till the result of the bug 22:44:16 Eric: i think its useful 22:44:38 on the media controller, its not possible to find out the combined state otherwise 22:44:58 Frank: agree with Eric, but need more discussion 22:45:08 JF: does it go in the CP? 22:45:58 Frank : could it go in as a bug outside the CP 22:46:10 JF: not sure, 22:46:22 easier to delete it later 22:47:47 general consensus: should go on the controller 22:49:07 Silvia: will add to the CP 22:49:11 item 7 22:49:22 backup 22:49:25 ended state 22:50:05 Silvia:: the onended event is not included, as Ian not clear what it means 22:50:24 think it is necessary 22:50:37 Eric: ended is required 22:51:18 Bob: agree, Mark: no opinion 22:51:34 consensus : keep it in 22:51:49 item 7 22:52:02 how to create controls for the combined grou 22:52:29 Silvia: how are the automatic controls created for a combined resource 22:52:51 Ian seems to thin its possible on each video element, and they will control the controller 22:53:05 this seems like an OK solution 22:53:32 its probably not possible to create one over multiple elements 22:53:55 Eric: my interpretation is that if show for any element, it works for all the elements 22:54:35 from a display point of view they will cover only one video element 22:54:42 JF: so this is a solved problem 22:55:03 return to autoplay 22:55:16 Judy: can we restate the question 22:55:43 silvia: should the controller have an autoplay idl attribute representing all the slaves 22:55:55 Judy: I think so 22:58:35 Sean: concerned that we are not clear about the semantics of the idl attribute 22:58:52 ...will is be controlling all of the elements, or only the first?
