<kaz> bob: explains his view, esp. existing features of HTML5 related this proposal

<Zakim> kaz, you wanted to suggest we include a bit more detailed example scenario (including actual video image :) and to

HTML5 LCWD comments

<kaz> bob: 5 comments so far

<kaz> ... one of them was reject, 13333

-> http://www.w3.org/Bugs/Public/show_bug.cgi?id=13333 Bug 13333

<kaz> bob: no discussion on the other 4

-> http://www.w3.org/Bugs/Public/show_bug.cgi?id=13357 Bug 13357

<kaz> mav: we went through couple of the comments

<kaz> clarke: we did 13333 and 13357 last week

<kaz> Clarke's message on HTML5 LC comments

<kaz> bob: explains 13358

<kaz> bug 13358

<kaz> bob: had discussion with accessibility guys as well

<kaz> ... they said this requirement is valid

<kaz> giuseppe: no objection, but question about "endorsement"

<kaz> clarke: acknowledging this is a comment from the IG

<kaz> unmute me

<kaz> mute me

<kaz> kaz: explains the situation about HTML5 LC comments

<kaz> ... all the 5 comments have submitted to HTML WG before the deadline and are under review

<kaz> ... although the comment period for the first LCWD ended yesterday, we can send more comments to the HTML WG

<kaz> ... those comments will be for the 2nd LCWD

<kaz> ... we can also send a message to the chairs of the HTML WG and Hypertext Coordination Group saying we as the whole IG endorse these comments

<kaz> giuseppe: fine to send a message

<kaz> bug 13359

<kaz> bob: A way is needed to identify the type of data in a track element

<kaz> giuseppe: use case here is regarding user script

<kaz> bob: right

<kaz> bob: type attribute is populated as mime type

<kaz> fd: even though the HTML WG refuse to add type attribute, it would be useful to have mechanism to handle IDL attribute from UA

<kaz> RESOLUTION: everybody is fine to endorse 13359

<kaz> bug 13625

<kaz> bob: There is no way to pass audio and video content metadata to the user agent that is required in some cases for playback.

<kaz> ... specifically, protocol, size and content protection mechanism

<kaz> ... would propose those three are added as attributes for HTMLMediaElement

<kaz> igarashi: it would be better to have a metadata attribute which can handle all those three than adding three separate attributes

<kaz> bob: you think so mainly because some more metadata would be added later

<kaz> igarashi: RFC defines content type and content feature

<kaz> bob: might be a good comment to be added to our comment 13625 itself

<kaz> giuseppe: media element has too many parameters...

<kaz> clarke: would suggest the IG co-Chairs to draft a message acknowledging these 5 comments

<Clarke> Thanks everybody

<kaz> [ adjourned ]
