EME status and bugs

glenn: EME draft last updated jul 16
... 15 bugs open

<glenn> http://tinyurl.com/7tfambo

<glenn> https://www.w3.org/Bugs/Public/show_bug.cgi?id=20944

Bug 20944 - EME should do more to encourage/ensure CDM-level interop

glenn: there were a couple of comments since the last meeting
... i proposed a way to resolve this bug
... Robert O'Callahan responded that it wasn't as strong as he desired
... i responded that he'd have to convince the group of his proposal
... he's requesting a fairly strong set of information about CDM
... i'm recommending a voluntary registry in the wiki

adrianba: i'd be okay with the wiki proposal

glenn: does anyone support robert's proposal?
... does anyone think we should keep it open for longer?

<glenn> https://www.w3.org/Bugs/Public/show_bug.cgi?id=20944#c15

glenn: can we get an action on the editors to implement the resolution in comment 15

johnsim: i'm a little unclear about what we're adding to the spec
... just a link to a wiki?

glenn: not suggesting making it a recommendation - in order to avoid collisions of key system names you can register here

johnsim: so it would just be a registry of the names?

glenn: there could be a comments field

adrianba: recommend glenn creates the wiki page, maybe with an example entry, and adds proposed spec text to the bug

<glenn> ACTION: glenn to draft wiki page to register CDM key system names [recorded in http://www.w3.org/2013/08/06-html-media-minutes.html#action01]

<glenn> Action glenn to draft spec language for inclusions as note to address comment #15 of bug 20944

Bug 20965 - EME results in a loss of control over security and privacy.

https://www.w3.org/Bugs/Public/show_bug.cgi?id=20965

glenn: i proposed a section called privacy concerns
... giving an example from webcrypto

<glenn> https://www.w3.org/Bugs/Public/show_bug.cgi?id=20965#c32

glenn: any input on this?

<glenn> adrianba: 2 parts to this issue

<glenn> ... specific information: what are privacy implications?

<glenn> ... does the design support take privacy into account?

<glenn> adrianba: so is api asynch at right time to be able to ask user for permissions, etc?

<johnsim> my microphone was muted at the time (???)

<glenn> adrianba: we've discussed this in relation to other topics

<glenn> ... between time session is created and session is ready, then user could be prompted if user decides not to allow use of EME

<glenn> ... but haven't exhaustively considered this topic

<glenn> ... henri's comment #9 also talks about storage of data

<glenn> glenn: to adrianba, do you have any recommendations on how to proceed with this bug?

<glenn> adrianba: prompt more discussion on ML ?

glenn: it seems to me that a better way would be to attempt to draft some minimal language that could be used to fill in a section on privacy considerations
... do we have a section in the document on this right now?
... any volunteers to draft this?
... i will go ahead an volunteer to draft language on potential privacy considerations

<glenn> Action glenn to draft language on potential privacy considerations

<trackbot> Error finding 'glenn'. You can review and register nicknames at <http://www.w3.org/html/wg/media/track/users>.

glenn: not an expert on this topic, will probably copy something from somewhere else and then put it on the list to solicit comments
... and also note other editorial comments, for example needing to look at API async

Bug 20966 - EME design trivializes the demanded loss of control of security and privacy demanded.

https://www.w3.org/Bugs/Public/show_bug.cgi?id=20966

glenn: in february, adrian asked for more information from the submitter
... comment 1 had asked for spec text to change
... i propose that we close this issue without prejudice because there is no information provided
... but it could be opened with new information
... any objection to this?

<ddorwin> Also note that privacy is being discussed/addressed in bug 20965.

<glenn> RESOLVED: close bug 20966 without prejudice due to lack of essential information; allow reopening only if substantive new info is provided;

glenn: any objections to this resolution?

<glenn> Action adrianba to implement closing 20966

<trackbot> Created ACTION-30 - Implement closing 20966 [on Adrian Bateman - due 2013-08-13].

Bug 21854 - Define MediaKeySession life cycle states and/or events

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21854

glenn: resolution that adrian would implement solution as discussed
... any progress?

adrianba: no progress yet - still a little discussion in the bug
... assume the resolution was without the state attribute
... i wasn't present at the end of the meeting last time

<ddorwin> I don't feel strongly about the state attribute (certainly not as strongly as I do about addressing the bug overall).

adrianba: not clear if the state attribute should be a separate bug or discussed here

<ddorwin> If people have use cases for the state attribute, that's fine. We could always add it later, though.

glenn: david, is there a way to resolve your comment?
... anyone proposing adding new information?
... then we should go ahead and act on the action and raise any issues

<glenn> https://www.w3.org/Bugs/Public/show_bug.cgi?id=21855#c5

Bug 21855 - Avoid network traffic and duplicate sessions for the same key(s)

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21855

glenn: sounds like this needs further thought
... if anyone has thoughts post to the mailing list
